1. Ethylene dioxide is produced by oxidation of ethylene as per the following reaction: 1 C,H, +02 → C,H,0 Fresh feed containing ethylene and air is mixed with recycle feed and mixed feed enters into a reactor. The proportion of C2H4: 02: Nzin mixed feed is 1:0.5:5.65 (on mole basis) 50% per pass conversion is achieved in the reactor are feed to the absorber where only all CaH«O formed removed by solvent absorption. The gases from the absorber containing C2H4, Oz and N2 are recycled each. To avoid built up of Nz in the system, small portions of recycle stream is continuously purged based on 100 mol ethylene is mixed feed, calculate the fresh feed to the process, the purge stream, recycle ratio, combined feed ratio and overall conversion of ethylene.

1. Ethylene dioxide is produced by oxidation of ethylene as per the following reaction: C„H, +502 → C,H,0 Fresh feed containing ethylene and air is mixed with recycle feed and mixed feed enters into a reactor. The proportion of C2H4 : O2: Nzin mixed feed is 1:0.5:5.65 (on mole basis) 50% per pass conversion is achieved in the reactor are feed to the absorber where only all C2H«O formed removed by solvent absorption. The gases from the absorber containing C2H4, O2 and N2 are recycled each. To avoid built up of N2 in the system, small portions of recycle stream is continuously purged based on 100 mol ethylene is mixed feed, calculate the fresh feed to the process, the purge stream, recycle ratio, combined feed ratio and overall conversion of ethylene.
