In a solid - liquid extraction process operated according to the principle of continuous reverse current, the oil of a nutrient will be extracted with pure hexane. A mixture containing 7000 kg of inert solid, 1500 kg of oil and 500 kg of hexane enters the process per hour. The upper stream leaving the total stage contains 65% hexane and 35% oil by weight. A total of 85% of the oil in the inlet current will be recovered. The underflow is constant at N=2.0 kg inert solid/kg solution; a. Find the amount and composition of the output current

The aqueous solution of acetic with a flow rate of 1000 kg/hr contains 30% acetic acid by mass and will be extracted in a countercurrent multistage process with pure isopropyl ether (IPE) to reduce the acetic acid concentration in the final raffinate phase (LN) to 2% by mass. a) Calculate the minimum solvent flow. b) Determine the theoretical number of steps required when using a solvent of 1.5 minimum solvent flow rate. c) Determine the number of theoretical steps using the McCabe-Thiele method.

A steady-state process to recover crystalline potassium chromate (K,CrOz) from an aqueous solution of this salt is required. Four thousand kilograms per hour of a solution that is one-third K,CrO, by mass is joined by a recycle stream containing 36.4% K2CrO7, and the combined stream is fed into an evaporator. The concentrated stream leaving the evaporator contains 49.4% K,CrO; 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,CrO, crystals and a solution that contains 36.4% K,CrO, 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,CrO,, is the recycle stream. 1- Draw the flowchart of the system and put all known information. 2- Calculate the rate of evaporation, the rate of production of crystalline K,CrO7, the feed rates that the evaporator and the crystallizer must be designed to handle, and…

Chemical process industries use complex equipments. Some of these are fractional distillation columns, catalytic cracking reactors, and bioreactors. In the bioreactor of one industry, the reactions below can occur to perform the fermentation process. The tank is initially charged with 7500 kg of 18% solution of glucose in water. After fermentation, 170 kg of CO2 produced and 100 kg of unreacted glucose left in the broth. Use atomic species balance in solving. C6H1206 - CzHsOH + CO2 CoH1206 - C2H;CO:H + H20 A.
