Abstract:

The operation of front-end depropanization and front-end hydrogenation process in an 800 kt/a ethylene plant is introduced. The problems occurred during the operation of high pressure and low pressure depropanizer and front-end C2 hydrogenation system are analyzed, and some optimization measures and suggestions are proposed for the problems.
