Problem 1: In a chromate crystal production process, a solution that is one-third K Cr04 by mass is joined by a recycle stream containing 36.4% K2Cr04, and the combined stream is fed into an evaporator. The concentrated stream leaving the evaporator contains 49.4% K,Cr04; this stream is fed into a crystallizer in which it is cooled (causing crystals of K Cr04 to come out of solution) and then filtered. The filter cake consists of K2 CrO4crystals and a solution that contains 36.4% K2Cr04 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% K2Cr04, is the recycle stream. Proposed flowchart is shown below to produce crystals from 4500 kg/hr of feed solution (mo). Solve for the following: m2 Xs = 1 m4 mo m1 m3 Evaporator Crystallizer & Filter XK = 0.494 XK = 0.33 Xs = 0.67 XK = 0.364 mo XK = 0.364 a) Complete process flow chart b) Determine process unknowns (; 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
