REMEDIATION PROCESS AND APPARATUS

摘要

Process for remediation of a fluid contaminated with alkylene oxide, comprising contacting the contaminated fluid with an aqueous absorbent to yield a fat absorbent having absorbed fluid, conferring intimate contact of fat absorbent and alkylene oxide and conversion of alkylene oxide; preferably a process which is part of a process for the conversion of ethylene to ethylene oxide with formation of byproducts, water and C02, wherein the product EO is isolated from the recycle gas and C02 is removed from the recycle in the C02 removal section and is remediated by the process as defined; apparatus for remediation of said fluid which comprises a converter having inlet means connected to the outlet of a fluid absorber for contacting fluid and aqueous absorbent, a holding unit having a volume V for the fat absorbent, and outlet means connected to the inlet of a fluid desorber; preferably as part of an apparatus for the conversion of ethylene to E0, more preferably part of an EO/EG apparatus, for the conversion of ethylene to ethylene oxide in which the apparatus is positioned in the vent stream.
