沼气脱硫应用络合铁脱硫技术，进行沼气中所含有的硫化氢气体的脱除，看似简单，实则也存在较多的工程要则在其中。
The complex iron desulfurization technology is applied to remove hydrogen sulfide gas contained in biogas. It seems simple, but there are many engineering essentials in it.
沼气的来源比拟多样，沼气是各种有机物质在隔绝空气，并在适合温度、湿度的条件下，经过微生物的发酵作用而产生的一种可燃性气体，普通是由多种气体组成的混合气体，含有甲烷、二氧化碳、硫化氢、一氧化碳、氢、氧、氮等气体，主要的成分是甲烷和二氧化碳，其它组成含量较低。
Biogas comes from various sources. Biogas is a kind of combustible gas produced by various organic substances through the fermentation of microorganisms under the conditions suitable for temperature and humidity. It is generally a mixture of gases, including methane, carbon dioxide, hydrogen sulfide, carbon monoxide, hydrogen, oxygen, nitrogen and other gases. The main components are methane and dioxygen The content of other components is low.
沼气熄灭能够供应能源，同时也能合成不需求的物质，所以应用发酵这个过程能够完成环保功用也能够回收应用能源。沼气应用过程普通都需求脱除硫化氢，这方面的脱除处置十分普遍和成熟。
Biogas extinguishment can supply energy, and at the same time, it can synthesize substances that are not needed, so the application of fermentation can complete the environmental protection function and can also recover energy. Generally, hydrogen sulfide removal is required in the application process of biogas, which is very common and mature.
传统的民用沼气池，采用氧化铁脱硫剂居多，量小，适用且便当。
The traditional civil biogas digesters mostly use iron oxide desulfurizer, which is small in quantity, suitable and convenient.
比照新近能够采用的络合铁脱硫技术，用于沼气脱硫时，我们倾向于讨论诸如范围化的中小企业发酵沼气池的处置。例如畜禽养殖沼气，城镇污水沼气净化，制药厂沼气，造纸厂沼气，酒厂，糖厂沼气，渣滓处置沼气池等都有沼气的处置需求。限制了络合铁脱硫应用于普遍沼气脱硫的缘由，主要还是在于，络合铁脱硫技术用于沼气，是在一定的范围段应用才有经济性，而同时络合铁脱硫技术用于沼气，是有一定的技术窍门在其中的。
Compared with the recently used complex iron desulfurization technology, we tend to discuss the treatment of fermentation biogas digesters in small and medium-sized enterprises. For example, biogas for livestock and poultry breeding, biogas purification for urban sewage, biogas for pharmaceutical plants, biogas for paper mills, biogas for distilleries, biogas for sugar factories, biogas digesters for waste disposal, etc. all have biogas disposal needs. The main reason that limits the application of complex iron desulfurization technology in general biogas desulfurization is that the application of complex iron desulfurization technology in biogas is economical only in a certain range, and at the same time, complex iron desulfurization technology in biogas has certain technical know-how.
从络合铁脱硫技术在国内应用的推行来看，国产化不断在相关研讨院停止，且主要在油田范畴，主要是早期络合铁脱硫催化剂由国外引进，价钱昂扬，技术费用较高，只能应用于价值较高的油气田才干支撑。但随着代理的开展，及大学，研讨院所，企业的推进，整个络合铁脱硫行业应用似乎步入快速开展。这其中做了较大奉献的唐山绿源环保公司，特地从事络合铁脱硫技术及硫化氢管理的民营企业做了较多的研发投入与市场耕耘。同时该企业也是国内络合铁脱硫范畴的探究者，开发培育者。
From the perspective of domestic application of complex iron desulfurization technology, localization has been stopped in relevant research institutes, and it is mainly in the field of oil field. The main reason is that the early complex iron desulfurization catalyst was introduced from abroad with high price and high technical cost. It can only be used in oil and gas fields with high value to support. However, with the development of agents, universities, research institutes and enterprises, the application of the whole complex iron desulfurization industry seems to be developing rapidly. Among them, Tangshan Lvyuan environmental protection Co., Ltd., which has made great contribution, has made more research and development investment and market cultivation for private enterprises specially engaged in complex iron desulfurization technology and hydrogen sulfide management. At the same time, the enterprise is also a researcher, developer and cultivator in the field of domestic complex iron desulfurization.
络合铁脱硫工艺在工程上应用碱性络合铁催化剂的氧化复原性质，吸收原料气中的H2S。H2S被络合铁催化剂直接氧化生成单质硫，络合铁转化为络合亚铁，然后在再生过程中鼓入空气，以空气氧化催化剂富液中的络合亚铁，使催化剂富液中的络合亚铁转化为络合铁，从而再生回用。产生的硫磺经过硫磺回收系统处置。
In the process of complex iron desulfurization, the oxidation recovery property of basic complex iron catalyst is applied to absorb H2S in feed gas. H2S is directly oxidized by iron complex catalyst to generate elemental sulfur, which is converted into iron complex. Then air is blown in the regeneration process to oxidize the iron complex in the rich solution of catalyst by air, so that the iron complex in the rich solution of catalyst can be converted into iron complex, so as to be recycled. The generated sulfur is disposed by sulfur recovery system.
沼气应用络合铁脱硫，特性有
Biogas is desulfurized by complex iron with the following characteristics

3. 可停止橇装一体化；

由于络合铁催化剂对硫化氢转化为硫磺的选择性到达99%以上，无副盐产生，也不存在要向外排放废液的状况，局部排放的气体经再生废气别离器分液回收携带的溶液后，是能够平安、无污染排放的。安装也不存在大的固废和噪声污染源。
As the selectivity of the complex iron catalyst for the conversion of hydrogen sulfide to sulfur reaches over 99%, there is no by-salt produced, and there is no need to discharge the waste liquid outward. The locally discharged gas can be discharged safely and without pollution after the solution carried by the regeneration waste gas separator is recovered. There is no large solid waste and noise pollution source in the installation.
