摘要:
A process for extracting a phosgene compound, comprising providing a membrane extracting unit comprising at least one extracting cell that comprises at least one membrane contactor module having at least two sides, a gas side and a liquid side; letting an initial gas stream comprising a phosgene compound flow on the gas side of the membrane contactor module; and letting an extractant liquid stream, suitable for dissolving a phosgene compound, flow on the liquid side of the membrane contactor module so that the extractant liquid stream absorbs the phosgene compound from the initial gas stream and provides a second extractant liquid stream enriched with the phosgene compound.

摘要:
A process according to the invention is a process to separate an initial fluid stream comprising phosgene and hydrogen chloride in at least a first and a second fluid stream, said first fluid stream being a hydrogen chloride enriched and phosgene depleted gaseous stream, said second fluid stream being a hydrogen chloride depleted and phosgene enriched stream. The separation is performed by feeding said initial fluid stream to a membrane separation unit, said membrane separation unit separating said initial fluid stream in a first and a second fluid stream
