Chemical engineering
Transcribed Image Text:Styrene (CSH8) is produced by the dehydrogenation of ethylbenzene (C8H10) in the
presence of steam at 600°C and 2.00 atm. Consider a tubular reactor operating with
15:1 steam to ethylbenzene feed ratio at the reactor entrance. At this temperature, the
reaction has an equilibrium constant Kp = 2.00 atm (K, is the equilibrium constant
based on partial pressures. For component a, the partial pressure is defined as pa =
YaP, where P is the operating pressure of the reactor and ya is the mole fraction of
component a. The chemical reaction is as follows:
C3H10 2 C3H3+H2
(a)
Determine the fractional conversion of the ethylbenzene to styrene at
equilibrium.
(b)
List two methods of varying the process variables for this process to
increase the fractional conversion of ethylbenzene to styrene across the reactor.
