A water solution contains 60% Na2S2O2 together with 1% soluble impurity. Upon cooling to 10oC, Na2S2O2· 5H2O crystallizes out. The solubility ofthis hydrate is 1.4Ib Na2S2O2· 5H2O/lb crystal free water.
The crystals removed carry as adhering solution 0.06 lbsolution/lb crystals. When dried to remove theremaining water (but not the water of hydration), the final dry Na2S2O2· 5H2O crystals must not contain more than 0.1 %impurity. To meetthis specification, the original solution, before cooling, is further diluted with water, On the basis of 100 lb of the original solution, calculate:
(a) The amount of water added before cooling.
(b) The percentage recovery of the Na2S2O2in the dried hydrated crystals.
For a reversible liquid phase reaction A-^R, the conversion is 33.3% after 8 minutes and equilibrium conversion is 66.7%. Find the rate equation for the reaction.
A vapor rate of 2500 kg/h is required and the vaporizer will operate at 6 bara. Size the vessel to restrict the carryover of liquid droplets. The liquid hold-up time need not be considered, as the liquid level will be a function of the thermal des..
A preliminary (Class 4) estimate of the ISBL capital cost of building a 200,000 ton per year ethanol plant by corn dry milling has been stated as $130 MM -30%/+50%.
Suppose that R2 is decreased to 0.5 min/ft2. Compare the old and new values of the ultimate gain and the critical frequency. Would you expect the control system performance to become better or worse, justify your answer.
