At a plant that manufactures styrene, the reactor outlet operates at 100 kgmol/hr, 760 mmHg, and 500oC. It contains 50 mol% hydrogen (H2), 30 mol% ethylbenzene (C8H10), and 20 mol% styrene (C8H8). The reactor outlet is then cooled and partially condensed, then separated into vapor and liquid streams in a flash drum. This operates as a single equilibrium stage. The hydrogen-rich vapor stream is sent to a desulfurization process. This stream must contain no more than 0.2 mol% styrene. You need to find the operating temperature to achieve this and the mole fraction of ethylbenzene in the hydrogen-rich stream under this condition. Assume that hydrogen is negligibly soluble in the liquid leaving the condenser. In order to achieve 0.2 mol% styrene in the hydrogen-rich vapor stream, to what temperature (in oC) must the condenser be cooled? What mole fraction of ethylbenzene is in the hydrogen-rich stream?
