Title:
METHOD FOR PURIFYING OLEFIN GAS AND METHOD FOR PRODUCING POLYOLEFIN
Document Type and Number:
WIPO Patent Application WO/2023/182466
Kind Code:
A1
Abstract:
A method for purifying an olefin gas in which an olefin gas including an organoaluminum component is brought into contact with water in a scrubber to remove the organoaluminum component, wherein the surface of a peripheral portion of a gas outlet of a gas nozzle that supplies the olefin gas to the scrubber is made to have a contact angle with water of 80° or more. As a result, in a continuous process of precipitating and removing the organoaluminum component by contacting the olefin gas containing the organoaluminum component with water, blockage of the purification system that hinders long-term continuous operation can be suppressed.
