Laundry energy consumption usually depends upon the type and quantity of clothes. Laundry services works in a way to maintain the quality of material required by customers. In our college, Laundry services start in the morning hours after collecting clothes from both ladies and men hostels. Our Laundry has power loads of 3 washing machines and 3 driers aligned opposite to each other for easy operation. Each motor in washing machine has a connected load of each 1.5 kW motors for washing and extraction. Dryer has two 1.5 kW motor with heat pump and blower motor. The plant has 6 tube lights, 1 fan load, with an elevator with 1.5kW motor. A uniform ironing press with 9 kW heater and 0.37 kW suction motor handles. All the uniforms like shirts, pants, overcoat, etc. [8]. Other non-uniforms are switched to vacuum table ironing with steam spray. An air compressor with 4 kW motor for pressurising air also used for door operation and extraction for washing machine and dryer as well as for operation of ironing press. The waste water coming out of the plant is passed to S. T. P.
Manufacture of Glycerine from Natural Fats and Oils
Published in Eric Jungermann, Norman O.V. Sonntag, Glycerine, 2018
Physical treatments used in the processing of crude glycerine include decantation, filtration, centrifuging, and evaporation/distillation. These physical operations are used to (a) remove fatty, insoluble, or precipitated solids, and (b) remove water. An important parameter for all physical operations is temperature: at low temperatures, glycerine is very viscous and difficult to handle or transfer (Table 3.8); at high temperatures, glycerine is unstable and subject to dehydration or polymerization. For these reasons, most glycerine processing is done at temperatures of 150–200°F. In this temperature range the water evaporation processes must be conducted under vacuum (Table 3.8).

A complete industrial steam ironing unit made for design rooms, tailors’ workshops, ironing services, alteration shops, small clothing manufactures, and so on comprising of a heated vacuum table, pressure steam generator and stream iron. The pressing station is designed as a compact industrial ironing unit with features similar to those of much bigger tables and generators. It is aimed at users who require professional finished results from compact equipment that is easy to set-up and use. It requires no special installation, uses standard tap water, and is powered by two standard 13-amp plugs.

The context in which the offer is taking place has a strong impact on the way a company is designing its commercial offers, both on the technical solution and on the delivery process. For this reason it is important to characterise the context with relevant information dedicated to (Figure 4): The current state of the market: For instance, some questions have to be answered, such as ‘Are there potential competitors?’, ‘Is it a market penetration strategy or an emerging market?’, ‘Is it a private or a public market?’,The customer's profile: Some questions about the potential client need to be addressed, such as ‘Is it a new or a regular customer?’, ‘Is it a strategic customer?’, ‘Are there any prices negotiated with this customer?’, ‘Have there been any problems with this customer in the past?’,The future state of the company in case of success: Some questions about the ability of the company to manufacture and deliver the technical solution in good conditions need to be answered, such as ‘What will the status of the order book be if we win the deal?’, ‘Will my human and material resources be available on D-Day?’, ‘Will the workshop be able to handle the workload of this business?’,The customer requirements: The needs, requirements or specifications must be carefully analysed to customise the solution that best suits the stakeholders. Customer requirements are considered non-negotiable and must be understood appropriately. In the same way than Shen, Wang, and Sun (2012), we consider that customer requirements can impact: a function of the technical solution, such as ‘a vacuum table is required for the CNC1 cutting machine’,a component, such as ‘the centrifugal vacuum pump referenced S55KFGTPO45 is the one to use’,a service, such as ‘the operators have to be trained to use this CNC cutting machine’,an economic indicator, such as ‘the price should not be over ’,a time indicator, such as ‘the CNC cutting machine must be delivered and installed within 6 weeks’.
