It is determined that the inlet temperature should be 268 oF (based on preheat exchanger limitations—see Reactor Feed Preheat/Effluent Cooler section) with an outlet temperature of 482 oF. The reactor operates at 231 psia. Literature sources indicate that typical reactor conditions are with temperatures of 230-260 oC and pressure at around 147-367 psia (12) The feed contains ethylene at 99.5% purity and oxygen at 99.5% purity. The inlet is 33% ethylene and 8% oxygen.
The following table gives the reactor inlet and outlet conditions and compositions:
