The document presents a project on the production of L-phenylacetylcarbinol (L-PAC) through fermentation. It includes a literature review on the fermentation process and usage of L-PAC. An economy analysis of the global demand and supply of L-PAC from 2006-2013 is presented. The process description includes fermentation in a bioreactor, centrifugation, precipitation, filtration and drying. Mass and energy balances are calculated for the bioreactor and distillation column. The pressure vessel designs for the bioreactor and distillation column are discussed. Heat exchanger designs and heat integration are analyzed. Control loops for bioreactor level, feed rate and antifoam are proposed. Wastew
