Vinyl chloride is used to make polyvinyl chloride, or PVC a widely used plastic with many
applications. As part of the process to produce vinyl chloride, ethylene is reacted with
chlorine gas to produce dichloroethane. dichloroethane is then heated to produce
vinyl chloride. You are tasked with designing a flash drum to remove unreacted ethylene
from dichloroethane before the heating step so the ethylene can be recycled to the
reactor. of a mixture of moldichloroethane DCE and mol ethylene
E at is to be flashed from bar to bar. The desired liquid composition is
moldichloroethane. Assume Raoult's Law applies an ideal mixture Antione's
Equation parameters are given below for and
a Draw a process flow diagram and do a degree of freedom analysis.
b Calculate the temperature of the flash drum and the molar flow rates
and compositions of the produc
t streams analytically.
Ethylene: A B C
dichloromethane: A B C
