Abstract

The invention discloses a recycling equipment and method of carbon disulfide in the hydrogen sulfide, which is characterized by the following: injecting hydrogen sulfide with carbon disulfide in the Claus recycling system directly; maintaining inner catalyst active property in the Claus reactor; sending the hydrogen sulfide with carbon disulfide in the adsorbing reactor to proceed adsorb and desorb operations alternately; transmitting the desorbed carbon disulfide in the refining unit to recycle carbon disulfide.

Description

technical field [0001] The invention relates to a separation method of a gas mixture, in particular to a device and a method for recovering carbon disulfide in hydrogen sulfide gas during the preparation of carbon disulfide. Background technique [0002] At present, during the preparation of carbon disulfide, the mixture of sulfur, carbon disulfide and hydrogen sulfide (process gas) from the reactor enters the preliminary separation tower for separation, and the unreacted sulfur is discharged from the bottom of the tower, while the mixed gas of carbon disulfide and hydrogen sulfide is produced by The top of the tower is discharged and cooled, wherein the condensed carbon disulfide is refluxed to the separation tower for washing and cooling the residual sulfur, and the hydrogen sulfide gas with about 0.5-8% carbon disulfide is directly discharged to the Claus tail gas recovery system, like this, On the one hand, part of the finished product of carbon disulfide was converted i...
