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…arrow_forwardM Inbox (2,372) - ftantill@ude X → с ← berarrow_forward
- 4.64. The gas-phase reaction between methanol and acetic acid to form methyl acetate and water CH;OH + CH3COOH = CH3COOCH3 + H2O (A) (В) (C) (D) takes place in a batch reactor. When the reaction mixture comes to equilibrium, the mole fractions of the four reactive species are related by the reaction eqilibrium constant Ky : = 4.87 YAYB (a) Suppose the feed to the reactor consists of n40,NB0, NCo, NDO, and no gram-moles of A, B, C, D, and an inert gas, I, respectively. Let į be the extent of reaction. Write expressions for the gram-moles of each reactive species in the final product, nA(2), nB(3), nc(E), and np(3). Then use these expressions and the given equilibrium constant to derive an equation for , the equilibrium extent of reaction, in terms of n20,.., N1o. (see Example 4.6-2.)

The resulting reaction mixture, “barium black ash”, contains 65%w/w soluble BaS and is to be leached with water. Black ash is to be fedto a tube mill at 100 tonnes per day, together with the overflow from thesecond of a cascade of thickeners, and the effluent from the mill is fed tothe first thickener. All the barium is dissolved in the mill. The strongsolution leaving the first thickener contains 20% w/w BaS by weight.Each thickener delivers a sludge with 1.5 kg liquid per kg of insolublesolid. Both liquids leaving each thickener are to have the same BaSconcentration. BaS lost with the final sludge should not exceed 1 kg perday.How many thickeners are needed?arrow_forward
