Problem 1: In a chromate crystal production process, a solution that is one-third K Cro, by mass is joined by a recycle stream containing 36.4% K_Croy, and the combined stream is fed into an evaporator. The concentrated stream leaving the evaporator contains 49.4% K Cr0s; this stream is fed into a crystallizer in which it is cooled (causing crystals of K CrO to come out of solution) and then filtered. The filter cake consists of K Crocrystals and a solution that contains 36.4% K Cro4 by mass; the crystals account for 95% of the total mass of the filter cake. The solution that passes through the filter, also 36.4% K,CrO4, is the recycle stream. Proposed flowchart is shown below to produce crystals from 4500 kg/hr of feed solution (mo). Solve for the following: 14 mo m2 x = 1 mz Evaporator ** = 0.494 m Crystallizer Xx = 0.33 Xs = 0.67 Filter Xx = 0.364 mo ** = 0.364 a) Complete process flow chart b) Determine process unknowns (m; and x) in all streams c) Determine the recycle ratio d) Determine the crystallization & filtration unit efficiency e) Amount of crystals that will be produced if the fresh feed flowrate is reduced to 1000 kg/hr f) Suggest two, at least, approaches to enhance the rate of crystal production. g) Determine rate of crystals production with the same feed flowrate ( 4500 kg/hr) if no recycle is considered h) Suggest two, at least, approaches to enhance the rate of crystal production. i) Determine rate of crystals production with the same feed flowrate ( 4500 kg/hr) if no recycle is considered
