METHOD FOR PRODUCING 2,3,3,3-TETRAFLUOROPROPENE |
摘要 |
The invention concerns a method for producing 2,3,3,3-tetrafluoropropene comprising: a fluoridation reaction of a halopropane and/or halopropene into 2,3,3,3-tetrafluoropropene by means of hydrogen fluoride; the recovery of a gas stream resulting from the reaction; the cooling and partial condensation of the gas stream resulting from the reaction into a partially condensed stream; the separation of the partially condensed stream into a gas fraction and a liquid fraction; the compression of the gas fraction into a compressed gas fraction; the compression of the liquid fraction into a compressed liquid fraction; the distillation of the compressed gas fraction and compressed liquid fraction in order to provide a stream of 2,3,3,3-tetrafluoropropene, a stream of hydrochloric acid, and a stream of unreacted hydrogen fluoride. The invention also concerns an installation suitable for implementing said method. |

1. A method for producing 2,3,3,3-tetrafluoropropene, comprising:
reactively fluorinating a halopropane and/or halopropene to 2,3,3,3-tetrafluoropropene using hydrogen fluoride; recovering a gaseous stream obtained from the reaction; cooling and partially condensing the gaseous stream obtained from the reaction, to give a partially condensed stream; separating the partially condensed stream into a gaseous fraction and a liquid fraction; compressing the gaseous fraction to give a compressed gaseous fraction; compressing the liquid fraction to give a compressed liquid fraction; distilling the compressed gaseous fraction and the compressed liquid fraction to give a 2,3,3,3-tetrafluoropropene stream, a hydrochloric acid stream, and a stream of unreacted hydrogen fluoride. |
