Claims (2)

불화 이소부티릴을 함유하는 기체/액체 유출액을 생산하기 위해 프로필렌, 일산화 탄소 및 불화수소를 첫번째 카르보닐화 반응기에 도입시키는 방법에 있어서, 하기 (A)-(H)단계를 포함하는 것을 특징으로 하는 일산화탄소 및 다양한 순도를 갖는 프로필렌의 이용을 개선하는 방법 : (A) 상기 유출액을 첫번째 상분리기내로 옮기고 유출액을 반응되지 않은 일산화탄소를 함유하는 바닥 액체 스트림 및 상부 기체성 스트림으로 분리시키는 단계 ; (B)(A)단계에서 나온 바닥 액체 스트림을, 이것이 프로필렌을 함유하는 기체성 스트림과 접촉되는 곳인 두번째 반응기내로 옮기고 근본적으로 모든 일산화탄소를 반응시키는 단계 ; (C)(B)단계에서 두번째 반응기로부터 나온 유출액을 상부 기체들이 액체 바닥으로부터 분리되는 두번째 성분리기로 옮기는 단계; (D) 두번째 상 분리기(C)에서 부터 액체 바닥 스트림을 제거하고, 이 스트림을 상부 기체들이 제거되고 근본적으로 불화 이소부티릴인 액체 바닥 스트림이 회수되기 위해 취해지는 가스제거 포트로 옮기는 단계 ; (E)(D)로부터 나온 상부 기체성 스트림을 취하고, 원한다면 그것에 보충 비활성 기체들을 가한후 첫번째 반응기에 도입된 불화수소에 이 스트림을 재순환시키고/거나 이 스트림을 (B)의 기체성 스트림에 역으로 재순환시키는 단계 ; (F)(A)에서 나온 상부 기체성 스트림을 압축기에 옮긴 후 ; (E)에서 나온 재순환 기체성 스트림에 옮기는 단계 ; (G)(C)에서 나온 상부 기체들을 취하고, 첫번째 부분을 (E)에서 처럼 재순환시키기 위해 옮기고 두번째 부분을 냉각단위로 옮기고, 상기 두번째 부분을 보다 적은 휘발성 물질의 바닥 스트림과 휘발성 물질의 상부 스트림으로 분리하고, (D)에서 회수하기 위해 불화 이소부티릴 스트림에 바닥 스트림의 일부분을 가하는 단계 ; (H)(G)에서 나온 상부의 덜 휘발성인 물질 스트림을 폐기물처리 하기 위해 이송하는 단계.A process for introducing propylene, carbon monoxide and hydrogen fluoride into a first carbonylation reactor to produce a gas / liquid effluent containing isobutyryl fluoride, comprising the following steps (A)-(H): A method for improving the use of carbon monoxide and propylene of varying purity comprising: (A) transferring the effluent into a first phase separator and separating the effluent into a bottom liquid stream and a top gaseous stream containing unreacted carbon monoxide; (B) transferring the bottom liquid stream from step (A) into a second reactor where it is in contact with a gaseous stream containing propylene and reacting essentially all carbon monoxide; (C) transferring the effluent from the second reactor in step (B) to a second component which separates the upper gases from the liquid bottom; (D) removing the liquid bottoms stream from the second phase separator (C) and transferring the stream to a degassing port where the top gases are removed and the liquid bottoms stream, essentially isobutyryl fluoride, is taken to recover; Take the upper gaseous stream from (E) (D), if desired add supplementary inert gases and recycle this stream to the hydrogen fluoride introduced into the first reactor and / or reverse this stream to the gaseous stream of (B). Recycling to; (F) after transferring the upper gaseous stream from (A) to the compressor; Transferring to the recycle gaseous stream from (E); Take the top gases from (G) (C), transfer the first part to recycle as in (E) and transfer the second part to the cooling unit, and transfer the second part to the bottom stream of less volatiles and the top stream of volatiles Separating into and adding a portion of the bottoms stream to the isobutyryl fluoride stream for recovery in (D); (H) Transferring the upper, less volatile material stream from (G) for waste disposal. 제 1 항에 있어서, 유출액이 50-90 부피%의 기체들의 혼합물인 방법.The process of claim 1 wherein the effluent is a mixture of 50-90 vol% of gases. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
