沼氣物理法脫硫技術的原理!

如果不對沼氣進行脫硫處理,那么將對沼氣設備造成很嚴重的腐蝕作用,所系說沼氣的脫硫工藝十分的有必要!下面小編就給大家普及一下沼氣物理法脫硫技術的原理!

If the biogas is not desulfurized, it will cause serious corrosion to the biogas equipment. So the desulfurization process of biogas is very necessary. The following edition will popularize the principle of biogas physical desulfurization technology for everyone!
物理法脫硫技術常常采用活性炭吸附法。活性炭具有多孔性,比表面積大,吸附性強,能脫硫、脫苯、脫臭、脫色等,可應用于化工、石油、天然氣、冶金、原子能、水處理、食品、紡織、醫(yī)藥、城建及環(huán)保等工業(yè)過程和人類生活中,是一種常用的吸附劑。
Activated carbon adsorption is often used in physical desulfurization technology. Activated carbon has porous, large specific surface area, strong adsorbability, can desulfurize, debenzene, deodorize, decolorize and so on. It can be used in industrial processes and human life such as chemical industry, petroleum, natural gas, metallurgy, atomic energy, water treatment, food, textile, medicine, urban construction and environmental protection. It is a commonly used adsorbent.
活性炭的吸附作用是一個催化反應,活性炭作為催化劑,吸附H2S后,催化H2S與其吸附的氧發(fā)生反應:
The adsorption of activated carbon is a catalytic reaction. Activated carbon acts as a catalyst. After adsorbing H2S, H2S reacts with the oxygen adsorbed by it.
2H2S + O2   2S + 2H2O
2H2S+O2 2S+2H 2O

生成的S元素被吸附到活性炭上。使用活性炭床(AS)吸附H2S可選用單床或雙床系統(tǒng),按H2S的濃度確定。雙床串聯(lián)吸附,個吸附床吸附H2S時,后面串聯(lián)的吸附床幾乎不起作用;當個吸附床穿透時(即個吸附床出口的H2S含量超標時),H2S會穿過進入第二個吸附床被吸附,此時個吸附床仍然起作用;當個吸附床飽和時(即個吸附床進口H2S含量和出口H2S含量基本相等時),需更換個吸附床的活性炭;更換后,新的吸附床作為第二個吸附床運行;如此更換,能夠大限度地利用活性炭進行吸附,保證脫硫精度且使使用壽命延長。
The formed S element is adsorbed on the activated carbon. Single-bed or double-bed system can be used to adsorb H2S by activated carbon bed (AS), which is determined by the concentration of H2S. When the first adsorption bed adsorbs H2S in series, the latter one hardly works; when the first adsorption bed penetrates (i.e. when the H2S content at the outlet of the first adsorption bed exceeds the standard), H2S will be adsorbed through the second adsorption bed, while the first adsorption bed still works; when the first adsorption bed is saturated (i.e., the H2S content at the inlet of the first adsorption bed and the H2S content at the outlet of the first adsorption bed). When the H2S content of the outlet is basically equal, the activated carbon of the first adsorption bed needs to be replaced; after replacing, the new adsorption bed operates as the second adsorption bed; thus, the activated carbon can be used for adsorption to the maximum extent, ensuring the desulfurization accuracy and prolonging the service life.
