Hand Soap Manufacturing Executive Summary Hand soap manufacturing entails various processing and packaging activities. In thehand soap manufacturing plant under study, the complexity and also size of the production operations is large because of the large quantities and high quality of resources involved (Garzena and Marina, 2004). The first procedure in the manufacture of hand soaps entails identification and the selection of the most appropriate raw materials and other production inputs. Raw materials are properly selected through various procedures; for example human safety, environmental safety, characteristics of finished products, compatibility with different input resources and costs. Traditionally, hand soaps are manufactured from oils or fats. They can also be made from the fatty acids that undergo reactions with the water soluble bases which are inorganic. The principle sources of fats include; beef or mutton tallow. Likewise, the main sources of oils include; coconut or palm kernel substances (Wansbrough, 2013). These raw materials are usually subjected to pretreatment so as to eliminate impurities, and realize the desired color and odor; plus the performance features required in the finished products. The chemical processes in the production of soap are discussed in this research paper in further details (Wansbrough, 2013). Effective hand soap production entails use of adequate energy. The production plants utilize both the thermal and electrical energy in the production process. All the production units are equipped with steam generation broilers. The electrical energy is mostly utilized in operating the refrigeration, lighting, drives and compressed air generation. The thermal energy is mostly used for production of steam from the broilers. Electric energy is supplied through the national grid system; the production units also have diesel generators which supplements electrical power in case of power failure (Simmons & Appleton, 2007). Because hand soap production is an energy intensive industry, there is need to ensure energy efficiency, so as to reduce energy costs. The best way to achieve this energy efficiency goal is to implement appropriate energy management system in the hand soap manufacturing plant. This system entails a program that ensures continuous improvement in the energy efficiency process. For the system to be effective, the management of the production plant and the staffs must be adequately trained in how it works. The commitment of all stakeholders towards energy efficiency also ensures success of the energy management system (Garzena and Marina, 2004). Mass and Energy Balance Material and energy balance is an important aspect in the soap manufacturing industry. Material balances ensure processing control in the soap manufacturing industry. The initial material balances are found in exploratory stages of a process which is new. The material balances are then improved in the pilot experiments for the plant during which the process is being initiated and tested. The material balances are thereafter refined and maintained to act as a control instrument in the production stages. When changes affect the process, material balances should be determined again. The increasing energy costs has ensured that the soap making industries identify methods of minimizing energy in the production process. Energy balances are required in the examination of energy usage in the total system of production; from raw materials to finished hand soap products. Computerization of the soap processing industries has ensured that mass and energy balances are set up and controlled readily in process management in order to maximize production outputs and minimize production costs (Garzena and Marina, 2004). The basic principle of the mass and energy balance illustrates that mass and energy introduced into the soap production process must equal the mass and energy produced out of the process (Mass / energy in = Mass / energy out + mass / energy stored). Mass balance for the soap manufacturing process is; Raw materials = Products + wastes + stored materials. Required raw materials weigh 150tonnes/day, and the finished product weigh 100tonnes/day. This means that the total weigh of stored materials and wastes is 50tonnes/day. The mass of the stored materials that will be utilized in future production processes in 20tonnes/day. This means that the mass of wastes is 30tonnes/day. Energy balance for the soap manufacturing process is; Energy in = energy out + stored energy. The energy in represents electricity, steam and fossil fuels; and the stored energy are illustrated through environment management. Energy in = 3378.97 + 111.25 + 1256.17 = 4746.39 KJ. Energy stored = 320.70 KJ. Therefore, energy out or utilized = 4746.39 – 320.70 = 4425.69 KJ. Summary Table on Hand Soap Manufacturing Item Quantity Raw Materials (oil, fat, caustic soda, water, salt, additives, sidium silicate, lubrication oil, wrapper paper, cartos) 150tonnes/day Fossil Fuel Use 3378.97 KJ/Kg Steam Use 1256.17KJ/Kg Electricity 111.25 Kwh/Kg Water 0.54Kgwater/Kgproduct Environmental Management 320.70 KJ/Kg Several assumptions are illustrated in the mass and energy balance. Firstly, it is assumed that production process will run smoothly without technical hitches like power failure or systems upgrade. Secondly, it is assumed that that all resources utilized in the production process are of the correct quantity and quality. Thirdly, it is assumed that energy will not be utilized in activities other than the hand soap production. Mass and Energy Utilization in a Hand Soap Manufacturing Plant Hand soap is one of the basic amenities required in modern households, for sanitary purposes. The manufacture of soap goes through several stages, which can be used to best explicate energy consumption in this manufacturing process. The production phases include saponification, mixing and washing, filtration or lye separation, neutralization, drying, plodding or other soap design considerations, and finally packing. The soap industry, just like most other manufacturing industries utilizes thermal and electrical energy in production processes. Virtually all production units have boilers installed, in order to generate required steam. On the other hand, electrical energy is primarily utilized for lighting, refrigeration, generation of compressed air, and conveyance of raw materials and final products. Thermal energy could be generated from a wide array of boiler fuels, ranging from coal and firewood to diesel combustion. The main processes that utilize energy include those using thermal equipment like saponification, vacuum drying, mixing and plodding. In contrast, electric equipment constitutes air compressors, lighting system, and refrigeration plant, machines that handle material, boilers, electrical drives, and diesel generators, among others. Better understanding of energy consumption can be gained from consideration of the soap production processes individually (Wansbrough, 2013). The first process of significance is saponification. During this manufacturing phase, raw materials or fats are treated using thermal heat. The latter form of energy is usually in form of steam. Thermal treatment is conducted in presence of caustic soda, an alkali, resulting in formation of glycerin and soap. The thermal heat promotes reaction of raw fats with alkali forming grains of soap. Further boiling of the mixture with alkali makes it possible to create more soap grains. The resultant soap during this phase comprises of approximately 65% soap and 35% water, among other trace materials like salt and glycerin. The subsequent production stage involves soap washing. This is necessary to remove the excess glycerin and water presently in the soap mixture. The solution comprising of soap is poured into a column and lye is added at the top. When the latter flows down the column several rotating disks keep turning, effectively agitating the mixture. These disks are turned by electrical energy, and the resulting turbulence makes sure that the lye and soap solution are adequately mixed. The soap is allowed to overflow, while the remnant lye is channeled away from the bottom of the column through regulated pumping. This shows that electrical energy is required for the pumping machine (Simmons & Appleton, 2007). The fourth stage in soap production involves lye separation. The stated separation is crucial to ensure that the final soap is adequately pure and wielding the right texture. Lye and soap are set apart using a centrifuge. This refers to a machine, whose varying rotating speed allows components in a fluid to separate on the basis of their density. Since lye is denser than soap, it remains at the bottom from where it is effectively drained away. The crucial point to note in this case is that, the centrifuge is propelled by electrical energy. The other soap manufacturing phase that does not require immense energy is the fifth one, which entails neutralization of the soap, fresh from the lye separation stage. This stage is necessary to make soap usable, since its alkali levels are still high because of caustic soda (NaOH) used in preceding stages. Neutralization is achieved through use of a relatively weak acid for example, citric acid, phosphoric acid, and fatty acids from coconut oil. Addition of preservative is also necessary at this stage of production. During this phase, mixing is still imperative necessitating use of electrical energy. The sixth step in this process involves drying the soap. This is vital because water levels should be reduced to a percentage of twelve or lower. Drying also referred to as vacuum drying is done through heating soap to approximately 1250C under intense pressure. The high pressure prevents water from over boiling and flowing over when soap can still be found in the pipes (Simmons & Appleton, 2007). The soap is then sprayed into evacuation chamber, from where it is extracted and processed further. Other than saponification, this is the other soap manufacturing stage that requires immense thermal energy generated from combustion of diesel and other fuels. It is important to take note of the fact that, the latent heat of vaporization which is lost after water boils off, lowers the temperature of soap to about 450C. It is under this lower temperature that soap solidifies on the walls of evacuation chambers. The steam utilized in the drying stage is obtained from boilers powered mainly by thermal energy. After drying, the soap stuck on walls of evacuation chambers is scraped off and then squeezed into lumps, a process known as plodding. After collection, the soap can then be compressed, cut and designed as desired. Electrical energy is necessary to propel the remnant materials towards recycling sections. For example, the remaining wet soap is conveyed to barometric condensers allowing condensation of vapor while making sure that the necessary vacuum is not compromised (n.a., 2000). Energy Utilization at Each Production Station per Kg of Product Station Energy Utilized (KJ/Kg of Product) Raw materials storage 307.53 Oil melting and blending 619.21 Saponification 723.11 Crutcher 513.24 Soap based storage tank 541.45 Plodding 734.52 Embossing 482.54 Cake cutting 239.00 Packing 114.96 Product storing 150.13 Development of an Energy Management Philosophy in a Hand Soap Manufacturing Plant Soap is a crucial commodity in any society, this means that it is produced widely and is likely to have a great impact on the environment, in terms of emissions and disposal of waste materials. Further, modern soap manufacturers must show commitment to energy and environmental conservation in general, in order to retain market positions, comply fully with government regulations and safeguard surroundings for the benefit of future generations. This can best be achieved if a soap manufacturing industry establishes and develops an inclusive energy management philosophy and culture (Neelis, Worrell & Masanet, 2008). This would be invaluable in ensuring reduction of pollutants and dedication of staff to environmental protection. Additionally, adoption of an energy management philosophy would make sure that the company saves on costs likely to be incurred in unnecessary energy investments. The energy management corporate culture would also ensure that the company can invest savings from improved energy consumption can be redirected to other areas, hence increasing chances of accruing greater revenue. The initial step toward creating this energy efficiency philosophy and later culture would be to create a clear set of objectives and goals. For example, the prospective framework should be founded not just upon compliance with government regulations, but also commitment of the facility to energy saving (Bardey, 1999). Following clear definition of objectives, a manager can proceed to create awareness programs. These would communicate project intentions to different partisans and convince them why it is necessary to have energy efficient measures in the process of manufacturing soap. At the time of energy management philosophy establishment in such an industry plant, there are aspects that are very precise to the industry and should be put into consideration. For instance, a manager could make recommendations such as replacing leaking steam valves as well as using certified products. Additionally, the managers should try and reduce heating time for the fat storage tank. It is preferable that the manager should reduce the hours to three. The management philosophy should also include the right amount of water to be utilized in saponification, in order to minimize steam consumption in the cooling stage. The philosophy should also include recovery of soiled and spilled fat during material handling section by steam treatment. Therefore, the philosophy could include protocols which can be utilized in energy regulation. This is the reason why the philosophy should be inclusive of standards and reporting elements allowing comparisons across the firm facilities. Additionally, it should allow implementation of better environmental policies and compliance with governmental laws (Bardey, 1999). The other important things that should be considered in the philosophy is personnel training. This is why workers should be encouraged to develop their skills and in training campaigns and programs provided by the organization. This way, the employees will provide the organization with necessary skills to get specific needs. The training will help employees to be better committed towards energy management. The philosophy should be strategized towards improving energy management as well as making it an imperative part of the company’s culture and planning process. The workers should also be trained on assessing principal energy use in the in organization in order to develop a crucial foundation of energy utilization and also setting development targets. Energy management philosophy should have goals and indicators which will help them in developing and shaping action plans. Therefore, employees should be taught on energy utilization as well as performance goals. These are some of the elements that will help in energy improvement, consumptions and performance (Bardey, 1999). There is need to have transparency when establishing an energy management philosophy. This will facilitate communication on issues pertaining to managing energy resources. This will only be attained by promotion of suitable energy management aspects and reinforcement of good management activities. It is also important to consider facilities’ evaluation and prioritization of energy improvement technologies. For that reason, it is important to successfully implement energy management philosophy, and consider the management time. This is because any successful implementation does not take a few days (Neelis, Worrell & Masanet, 2008). The workers should include commitment, effort, time, expertise, and repetition of long-term rewards. It is extremely imperative for the management to have proper mechanisms which will make the philosophy sustainable. The latter could also entail financial support, preparation, as well as execution of a conscious environment for hand soap technology solutions. Analysis of a Hand Soap Manufacturing Industrial Facility Soap Saponification Vessel is an industrial facility. Soap manufacturing process is done in special designed equipment and in many cases they are heavy vessel. Saponification vessels have been designed for better expediency in operation and better saponification procedure. During the process the oil is heated in the vessels by use of steam from the boilers in proper quantities. The vessels are designed to withstand high heat and also cool to substantial degrees (Basu, Pranab, & Thakur, 2014). The Steam Boiler is another industrial facility.The steam boiler is utilized in steam generation from the water. The steam is imperative because it is needed for heating the oils in the soap saponification vessels. The steam boiler is also used in making sure hand soap manufacturing is done on time and with the right heat conditions. Soap chips machine is also a very important machine in the industry. This is because of its use in making soap chips of soap bars in different sizes as required. It is imperative to convert the soap bars into chips in order to have properly dried products. Bar Production The hand soap production process is tasking especially because of its use of "Finishing Line". There are different processes and equipment that comprise soap production and are discussed herein. A mixer is also called an Amalgamator. This is a machine that is utilized in the mixing of the soap base which is also called soap chips to integrate color, fragrance as well as other ingredients that are imperative to the production (Dunn, 2010). The 1st refiner machine is used to take soap chips mixture from the mixer into the fine mesh screen. This is a process that is used in making the soap have necessary factors which are more enjoyable to the customers. For instance, some of the users would like hand soap that has aspects become more homogeneous. The screen can have 10 mesh, 30 mesh or 50 mesh, but that depends on the application. The process takes bouts 3-n 4 roles (Dunn, 2010). The second refiner usually repeats the 1st refiner process for homogeneity increment. In some cases, the process is usually eliminated but that depends on its application. The Vacuum Duplex Plodder machine utilization comprises of two stages. The 1st stage in the vacuum duplex plodder is another refining which is the last step in the refining process. In the second stage, a machine called the extruder is used shape the bars in and continuous billet. This stage is connected via a vacuum chamber that acts as a de-aerate to the soap. The extruder is commonly known as a "Plodder". The plodder produces long continuous hand soap bars (Garzena and Marina, 2004). The Cutter is used in cutting the soaps into small pieces. The machine is fully automated and incessantly cuts the billet into small slugs. The stamper is also known as the "Press". The stamper gives the hand soap slug the final shape s well as embossing the logo of the hand soap. The Die Chiller is utilized in the last process to prevent the hand soap from sticking to the die. This can impend its removal thus the Chiller is utilized in circulating super chilled liquid throughout the die (Garzena and Marina, 2004). Energy Efficiency in the Hand Soap Manufacturing Industry Energy is a very significant cost factor in soap manufacturing industry. Energy efficiency enhancement is the most important procedure of reducing the energy costs (Simmons & Appleton, 2007). This research paper discusses the energy efficiency technologies and practices that can be utilized in the soap manufacturing industry. The first energy efficiency practice entails changes in staff attitudes or behaviors. Staffs should be given adequate training on their company’s approach to energy efficiency in daily work practices. All employees should understand effective energy use and strategies for energy efficiency enhancements; positive changes in employee behavior like switching off lights when not in use is important for long term energy efficiency. Secondly, the soap manufacturing industry engages in environmental management system like ISO 14001 and Six Sigma. These approaches ensure energy efficiency because they enable the company to track or monitor the energy usage. The industry combines the energy management strategy with ISO 14001 strategies and hence there is large impact in energy saving. Minimizing the green house gas emissions has an effect of reducing energy emissions and usage levels. Energy in the soap manufacturing plant should be managed effectively through energy management programs. These programs present the most cost effective and efficient methods of ensuring proper energy efficiency. Continuous improvements in energy efficiency occur where there is strong organizational commitment. Energy management programs ensure that there is a continuous and ongoing improvement in energy efficiency. The Energy Star program ensures that soap manufacturing plants identify the significant aspects in energy management programs. Successful energy program starts with a strong organizational commitment to energy efficiency. This entails giving energy management responsibilities to the Energy Director, formulating energy policy, and forming an interdepartmental energy team (Dunn, 2010). Procedures are thereafter established to analyze performance through continuous review of energy efficiency information, assessment and benchmarking. The technical assessment enables the organization to develop energy use baseline and improvement strategies (Simmons & Appleton, 2007). One Lined Diagram of the Production Facility Energy Management Recommendations Energy efficiency improvements ensure creates opportunity for savings on energy costs and minimization of CO2 emissions. Therefore, soap manufacturing plants must work hard to ensure energy efficiency. Several energy management efforts can be employed by the hand soap manufacturing plants. To begin with, the plants should install energy efficient control systems and lightening. The plants should have energy efficient lighting policies which they must strictly adhere to. Secondly, the plants should participate in third party energy surveys, which ensure implementation of several energy saving projects. Finally, the soap manufacturing plants should collectively form a global energy reduction team, which energy and environmental management experts. This team is responsible for leading the energy efficiency programs through identifying and communicating best practices in energy management. Conclusion The material and energy balances prove to be important for a hand soap manufacturing plant, or any other organization. This is because the balances enable us to understand emissions or losses which were previously unknown. The material and energy balances also helps in ensuring the identification of the improvements made in the soap production process, and evaluating the cost benefits. References Bardey, C. (1999).
