Title:
ACETYLENE SEPARATION METHOD AND ACETYLENE SEPARATION SYSTEM FOR SEPARATION OF ACETYLENE FROM RAW-MATERIAL ETHYLENE
Document Type and Number:
WIPO Patent Application WO/2017/086307
Kind Code:
A1
Abstract:
This acetylene separation method for separating acetylene from raw-material ethylene includes: an acetylene separation step of dissolving the acetylene in the raw-material ethylene in an absorbent, so as to separate the acetylene from the raw-material ethylene; and a carbon monoxide removal step of removing carbon monoxide from the absorbent, in which the acetylene separation step separates the acetylene from the raw-material ethylene using the absorbent from which carbon monoxide has been removed in the carbon monoxide removal step. Furthermore, this acetylene separation system (1) includes an acetylene absorption column (11) that separates acetylene from the raw-material ethylene by dissolving the acetylene in the raw-material ethylene in an absorbent, and a carbon monoxide removal device (12) which removes carbon monoxide from the absorbent. According to the present invention, when separating acetylene from raw-material ethylene by contacting an absorbent with the raw-material ethylene, carbon monoxide, with which contamination was inevitable, can be removed.
