Abstract

The invention relates to a tail gas processing device and method, concretely a tail gas processing device and method in the CS2 preparing course, adopting a mode of integrating multistage Claus combustion furnace with low-temperature Claus process to process the tail gas, and makes gross recovery of S up to 99.5% above; and in the whole operating course, the catalyst regeneration and cooling are both completed by the system itself, so that the energy comsuption is low, pollution is less, and the exhausted tail gas can completely meet the requirements of national related effluent stardards, and the whole operating course is controlled by PLC program controller, thus implementing continous operation and reducing workers'labor strength.

Description

technical field [0001] The invention relates to a tail gas treatment equipment and method, in particular to a tail gas treatment equipment and method in the carbon disulfide preparation process. Background technique [0002] As we all know, the methane method to produce carbon disulfide production equipment has a large output and a large amount of tail gas. During the reaction, one ton of carbon disulfide is produced at the same time about one ton of hydrogen sulfide. At present, the Claus process is used to recover sulfur at home and abroad, and then the sulfur is returned to the production of carbon disulfide. The device is used as a raw material, and it is also a traditional process that has been used all the time. Claus combustion furnace uses artificial alumina catalyst instead of natural aluminum ore to recover hydrogen sulfide, which improves the efficiency. The original one-stage conversion of Claus combustion furnace is changed to multi-stage Conversion, the convers...
