there are many ways to perform a separation some of these including: distillation, absorption, stripping, and extraction. the science of separation revolves around the presence of two phases that are in contact and equilibrium (wankat, 2012). figure 1. separation methods by property.
process requires longer residence times and when the solutions are easily separated by gravity. they require a large facility footprint, but do not require much headspace, and need limited remote maintenance capability for occasional replacement of mixing motors.
design for manufacturing definition: dfm is the method of design for ease of manufacturing of the collection of parts that will form the product after assembly. ‘optimization of the manufacturing process…’ dfa is a tool used to select the most cost effective material and process to be used in the production in the early stages of product design.

for completion of the fermentation process is 15 –20 hours. the fermentation process is understood to be completed when the effervescence stops. other measurement like specific gravity etc., are also taken to assess the completion of fermentation process. fermentation is an exothermic reaction. hence, the temperature rises during the fermentation process. to maintain the temperature at 36 degree c., the

step 4 - lye separation the lye is added at the top of the washing column, and the soap removed from the column as overflow. as the lye is added near the overflow pipe the washed soap is about 20% fresh lye, giving the soap unacceptably high water and caustic levels. separating off the lye lowers the electrolyte levels to acceptable limits.

casting is a manufacturing process in which a solid is dissolved into a liquid, heated to appropriate temperature (sometimes processed to change its chemical formula), and is then added into a mold or cavity. thus, in just one step, complex or simple shapes can be crafted from any kind of metal that has the capability to be melted.
further processing to finished product takes place. process validation (active substance and finished product) the critical steps of the manufacture of the finished product have been validated using pilot scale and full-scale batches: influence of the mixing parameters during
