5046kg/hr mass flow rate of calcium fluoride (Caf2) with a purity of 99% by weight reacts with sulfuric acid to produce hydrofluoric acid (HF). The reaction occurs with 97% conversion and the reaction equation is given below: CaF2(solid)+H2SO4(gas)CaSO4(solid)+2HF(gas) Solid by-products, unreacted solid reagents, and impurities are taken from the bottom of the reactor. From the top of the reactor, the gas - phase HF and unreacted H2SO4 are taken and sent to the bottom of an absorption column. 99% of the HF and 99% of the H2SO4 are absorbed by the water sent from the top of the column, and the aqueous acid solution contraining 40% acid (HF+H2SO4) by weight is taken from below the column. 1% of each of the acid vapors comes out from the top of the column without bein absorbed. (ca:40, F:19, H:1, S:32, 0:16) A) Draw the block flow diagram B) Establish the mass balance for each device and for the entire system. 5046kg/hr mass flow rate of calcium fluoride (Caf2) with a purity of 99% by weight reacts with sulfuric acid to produce hydrofluoric acid (HF).
