Title:
PROCESS METHOD AND SYSTEM FOR CO-PRODUCTION OF PROPANE DEHYDROGENATION DEVICE AND ETHYLENE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/232453
Kind Code:
A1
Abstract:
The present invention relates to a process method and system for co-production of a propane dehydrogenation device and an ethylene device. The system comprises an oil-gas water scrubber, a rich gas compressor, a rich gas compressor outlet cooler, a steam-water separator, a rich gas dryer, a cold box, a gas-liquid separation tank and a condensate delivery pump. The process method eliminates the need for a rectification system for propane dehydrogenation, and uses a rectification system of the ethylene device to separate materials of an ethylene device and a propane dehydrogenation device. The investment in equipment is reduced, the area occupied by the apparatus is decreased, and great practical value and economic benefit are achieved.
