This paper introduced the basic principle of ethylene recovery from the vent gas of vinyl acetate plant with membrane separation technology, and optimized the process parameters like permeate/residue ratio, the flowrate of inert purge stream, temperature, and ethylene recovery rate.

Ethylene yields in cases of naphtha crack- ing,naphtha and ethane co-cracking and ethane cracking in millisecond furnace are compared with each other.

In the process of ethylene production,ethylene yield cannot be measured on-line via traditional approaches.
