Process for the recovery of carbon disulfide from a steam/carbon disulfide mixture

摘要

In the process for recovering carbon disulfide from a steam/carbon disulfide mixture, which is produced when the wastewater from the yarn cutters and the suspension water are treated with steam during the manufacture of viscose rayon, the vapors so produced are cooled by means of a liquid spray, drawn out of the vapor condenser and then condensed. The non-condensable constituents are removed via a trap and the liquefied carbon disulfide is separated from the remaining water. Specifically, the liquid used to spray the vapors is preheated by the thermal energy recovered from the cooling of these vapors, and the hot water thus obtained is then used for other purposes.
