Vulcanizing agent for removing hydrogen sulfide

Abstract

The invention relates to the field of desulfurizing agents, and specifically relates to a desulfurizing agent for removing hydrogen sulfide. The desulfurizing agent is prepared from the following raw materials in parts by weight: 70-90 parts of nanoscale zinc ferrite, 5-20 parts of a binder, and 5-10 parts of a transition metal accelerant; the desulfurizing agent, prepared from the nanoscale zinc ferrite, the binder and the transition metal accelerant according to a certain ratio, is compact in atomic arrangement and stable in crystal form, therefore the prepared desulfurizing agent has the advantages of high mechanical strength, little possibility of active component loss and good water resistance, and the hydrogen sulfide content in ammonia gas can be reduced to 0.01 mug / g or below, thereby meeting the sulfur-containing requirements of liquid ammonia for chemical industry and environmental protection.

Description

technical field

[0001] The invention relates to the field of desulfurizing agents, in particular to a desulfurizing agent for removing hydrogen sulfide. Background technique

[0002] In the industrial production process of petroleum smelting, because the raw materials contain more sulfur-containing substances, during the production process, the reaction of sulfur-containing substances will release a large amount of hydrogen sulfide, so sewage stripping devices are usually installed in refineries Purify the sulfur-containing and ammonia-containing sewage discharged from each production unit of the refinery, and recover hydrogen sulfide and ammonia at the same time. After the hydrogen sulfide is recovered, sulfur is produced by the sulfur recovery unit, and ammonia is compressed by the ammonia compressor to produce liquid ammonia or directly produced ammonia.

[0003] Since the recovered ammonia gas also contains water, hydrogen sulfide and other impurities, it will have a gr...
