ChE Thermo Aspen Homework 1. Use Aspen to do a liquid-liquid flash calculation for the mixture 0.5 mole fraction water in ethyl acetate separated at 1 atm pressure and 25C. The experimental results are given in the table below for comparison. Try various thermodynamic packages. Which package fits the experimental data best. Organic Compound Solubility in Water Solubility of water in (Mole%) (Mole%) Ethyl acetate 1.7 14.3 2. In the manufacture of ultra pure silicon, we have a reaction that converts metallurgical grade silicon, silicon tetrachloride and hydrogen to trichlorosilane with some impurities. The reaction takes place in a fluid bed reactor with powdered silicon being fluidized. After reaction in a fluid bed reactor the silicon solids are removed with a cyclone and we are left with the following gas phase mixture at 600 F and 410 psia: Component H2 Silicon Tetrachloride (SiCl4) Trichlorosilane (SiCl3H) Dichlorosilane (SiCl2H2) HCl Mole % 57.7610479438 28.13081650139 13.00813555481 1.07000000 0.030000 Determine the temperature needed for a flash to separate out a stream that is 0.96 mole fraction in hydrogen for recycle to the fluid bed reactor keeping the pressure constant so that the little compression is needed for the recycle. The liquid mixture produced with this flash should also be listed.
