Abstract: Taking the revamping of a 1.1 MTA ethylene plant as an example, this paper introduces the process technical characteristics of the quench oil tower system for ethylene separation. It discusses the revamping scheme for the internals of the quench oil tower emphatically. After the application of a new type of high-throughput orthogonal wave tray, the problem of large increase of gas-liquid load in the pan oil section of the quench oil tower is solved successfully. This provides reference for the selection of revamping schemes for tower internals in similar devices in the future.
