Description
Affiliated technical field
The present invention relates to a kind of desulfurizing method of exhaust gas, particularly a kind of sulfur method of sulfide hydrogen mist.
Background technology
Developing rapidly of industry such as modern coal, oil, natural gas produces a large amount of sulfide hydrogen (H in this process
2S) mist.Typical this class mist is just like Crouse's gas (Claus), and no matter the needs from technology still are the needs of environmental protection, and the desulfur technology of wherein hydrogen sulfide is become extremely important industrial process spy.Be not the strict demand of environmental protection in modern age, various countries divide to divide study cheaply, non-secondary pollution, resource and high efficiency processing method become the target of research.
At present, the method for handling hydrogen sulfide containing mist both at home and abroad can be divided into two big classes: i.e. dry method and wet method.
Be divided into two big classes in the dry method again: i.e. absorption method and Crouse (Claus) method.
Absorption method: adopt as activated carbon, molecular sieve, polyvalent metal oxides, complexing molysite etc., the hydrogen sulfide in the mist is adsorbed.Many documents and patent report are arranged: as the preparation＜gas purification of efficient normal temperature iron oxide desulfurizing agent〉the 5th the 1st phase of volume in 2005; Nano-ZnO desulfurizing agent surface texture and room temperature remove H
2The research of S performance, in August, 2005 Chinese Journal of Inorganic Chemistry the 8th phase.Zhang Jinxing, Li Xueling, Wang Shudong etc.Modified activated carbon low temperature removes the experimental study [J] of COS. Liaoning chemical industry .1998; 27 (2): 102～104.BAGREEV A, BANDOSZ T J.On the mechanism of hydrogen sulfide removalfrom moist air on catalytic carbonaceous adsorbents[J] .Ind Eng Res, 2005,44 (3): 530-538.Tseng R-L, Tseng S-K.Pore structure and ad-sorption performance of the KOH---activated carbonsprepared formcorncob.Journal of Colloid and Inter-face Science.2005.287:428-437 etc.Yet, such processing mode, cost is very high beyond doubt, and can not or be difficult to the sulphur resource.Therefore, the desulfurization that this method is used for a large amount of gases is very uneconomic, also can produce secondary pollution; Certainly, handle still optionally for the stingy amount in producing as fine chemistry industry.
Claus method (Claus): be two sections doctor treatments again.Many patents and bibliographical information are arranged both at home and abroad, as: CN96100479.7 Holland VEG GRI; CN 99809986.4 Dutch Gastec N.

Wet method: wherein the method for CN86101352 Japan JGC Corporation merits attention very much, and mist is pressurized to 0.5Mpa to this method and sulfur dioxide feeds in the pressurized reactor in the lump, and the control pH value is 2, generates the sulphur of oil-in-water attitude.Become the sulfur dioxide retrieval system to handle at 200-350 ℃ with air burning in sulphur again.This method can obtain product sulphur or sulfur dioxide by the processing to mist, thereby realizes the resource of sulphur in the mist.But the compression of a large amount of gases is proposed high request to equipment and technology undoubtedly, and higher energy consumption also is an adverse factors very.
Document is more arranged: H in the liquid phase
2S and SO
2Kinetics research, the 17th volume colleges and universities' Chemical Engineering journal in June, 2003 the 3rd phase.Sulfur dioxide and hydrogen sulfide in bubbling reactor, have been studied at three kinds of pH value solution not, i.e. the aqueous solution, hydrochloric acid one sodium citrate buffer and sodium carbonate, the reflex action in the sodium bicarbonate buffer solution.
Chinese patent 201010276614.4 discloses TMG hydroxy-acid salt composite desulfurizing agent, but unexposed its is used for the sulfur removal technology and the method for sulfide hydrogen mist.
