Abstract
The invention discloses a method for converting hydrogen sulfide gas in production of thiofide MTB-a novel single sulfur method secondary conversion process. The method is characterized in that: the hydrogen sulfide gas is introduced into a sulfur production furnace and is combusted. The combustion parameters are that: the ratio of the hydrogen sulfide gas to air is 1:2, the temperature is 800 to 1,000 DEG C, and the reaction is performed under the action of carbon serving as a catalyst. The sulfur is separated out through the secondary conversion. The method has the characteristics of: the recovery rate of the sulfur is over 95 percent, the recovery conversion rate of H2S acid gas is over 99 percent, the technology is mature, the investment is low, the operation is easy to control, the method is safe and reliable, the energy consumption is low and the production is safe.
Description
Technical field
The present invention relates to the method for transformation of hydrogen sulfide in a kind of rubber vulcanization accelerant MBT production, belong to the thiofide production technical field.
Background technology
Rubber Chemicals Industries is the part that reassembles into of China's rubber industry, has also become the important component part of China's fine chemistry industry.Captax is the important kind of thiazole accelerator, also is the raw materials for production of the numerous promotor in downstream.
Will adopt with aniline present domestic production corporate boss is that raw material and dithiocarbonic anhydride, Sulfur react and obtain, wherein be divided into high-pressure process and non-pressure process again, domesticly in recent years progressively begin to select high-pressure process, because high-pressure process can realize serialization production, the high pressure aniline process is synthetic under High Temperature High Pressure aniline, CS2 and three kinds of raw materials of S, separates, is purified to captax through a series of aftertreatments again.From the difference of aftertreatment, can be divided into acid-base method and solvent method again.Both common drawback are: high pressure synthetic waste gas H2S and superfluous CS2 do not reclaim, and consume high.H2S content is measured little but the concentration height more than 83% in the synthetic waste gas that produces of M.Rubber Chemicals Industries is successfully introduced claus process and has been solved this difficult problem.Shandong Shanxian Chemicals Co., Ltd. is on the basis that contrast is investigated repeatedly, adopted single flow partial combustion process to transform super claus process for three grades by the design of three-dimensional petrochemical industry project company limited, this is installed on formal some stove test run on September 27th, 2007, this technology characteristics such as maturation, operation control is simple, safe and reliable, energy consumption is low that possess skills have creatively been realized once succeeding in the test run.The online ratio Analysis instrument fine setting air output of this process using international most advanced level, thereby improve H2S sour gas recovery transformation efficiency and reach 99.6%, control the discharging of SO2 in the tail gas simultaneously, exhaust emissions reaches national GB16297-1996 " discharge standard of air pollutants ", the sulfur purity that reclaims is 99.99%, reaches GB GB/T2449-2006 premium grads specification.Puyang WeiLin chemical engineering Co., Ltd adopts " absorption condensation+two section Crouse " technology also effectively to administer acid H2S gas, and has recycled the CS2 in the tail gas, has realized environmental benefit and economic benefit preferably.We then provide a kind of single sulphur method secondary conversion technology.
Summary of the invention
Technical scheme of the present invention is to realize like this.1, the method for transformation of hydrogen sulfide during a kind of rubber vulcanization accelerant MBT is produced is characterized in that comprising following process:
(1) will burn in the hydrogen sulfide feeding system sulphur stove.
(2) above-mentioned (1) combustion parameter is: the proportion of hydrogen sulfide and air is 1: 2, and temperature is reacted under the effect of C catalyst at 800-1000 ℃.
(3) above-mentioned (1) burning was isolated sulphur with mixed gas through waste heat boiler and first-stage condenser after 0.5-1.5 hour.
(4) above-mentioned (3) condensed gas is referred and synthesized with the partial combustion mixed gas again, when promoting temperature to 800--900 ℃, enters secondary condenser through the one-level convertor and isolates sulphur.
(5) above-mentioned (4) condensed gas is referred and synthesized with the partial combustion mixed gas again, when promoting temperature to 800--850 ℃, enters three grades of condensers through the secondary convertor and isolates sulphur.
The invention has the advantages that: the rate of recovery of sulphur is more than 95%, and the H2S sour gas reclaims transformation efficiency and reaches more than 99%, and technology maturation, less investment, operation control is simple, safe and reliable, energy consumption is low, production safety.
