Abstract
An ethylene oxide (EO) production process comprising (a) introducing a first reactant mixture (CH, O) to a first reactor to produce a first effluent stream (CH, CH, O); (b) introducing a second reactant mixture to a second reactor to produce a second effluent stream (EO, CH, CH, O); wherein the second reactant mixture comprises at least a portion of first effluent stream; (c) separating the second effluent stream into an EO product stream (EO) and recycle stream (CH, CH, O); wherein ethylene is not separated from recycle stream and/or first effluent stream; and (d) recycling a first portion of recycle stream to the first reactor, and a second portion of recycle stream to the second reactor; wherein recycle split ratio <0.6; and wherein recycle split ratio is defined as ratio of volumetric flowrate of first portion of recycle stream divided by the sum of volumetric flowrates of first portion and second portion of recycle stream.
