對煤氣脫硫工藝的認識！

首頁- 新聞資訊 > 公司新聞

2021-06-05

焦爐煤氣是寶貴的資源，作為工業或民用燃料，是一種清潔能源。在煉焦過程中，原料煤中有30%～35%的硫轉化成硫化氫等硫化物，與氨氣、氮硫化物一起形成煤氣中的雜質，硫化氫具有很強的腐蝕性，焦爐煤氣若不脫除硫化氫會嚴重腐蝕設備，作為民用燃料會污染環境，損害人們身體健康；下面讓我們來了解一下有關煤氣脫硫工藝的相關知識吧。

Coke oven gas is a valuable resource, as an industrial or civil fuel, is a kind of clean energy. In the coking process, 30% - 35% of sulfur in raw coal is converted into sulfide such as hydrogen sulfide, which forms impurities in the gas together with ammonia and nitrogen sulfide. Hydrogen sulfide is highly corrosive. If hydrogen sulfide is not removed from coke oven gas, it will seriously corrode the equipment. As a civil fuel, it will pollute the environment and damage people's health; Now let's learn about the relevant knowledge of gas desulfurization process.

焦爐煤氣脫硫工藝，經過幾十年的發展形成了一些傳統流程，該流程簡單，易操作，生產穩定，在焦化生產中發揮了重要作用；焦爐煤氣脫硫，有其特殊性，從工藝上講，在脫硫反應過程中，同時伴隨氧化再生析硫過程，解析的硫能及時分離出來，使反應成硫與帶出的硫成正比，達到物料平衡，將生產納入良性循環的控制，追求高能、低耗、長周期、安全、經濟運行。

After decades of development, coke oven gas desulfurization process has formed some traditional processes, which are simple, easy to operate, stable in production and play an important role in coking production; Coke oven gas desulfurization has its particularity. In terms of process, in the desulfurization reaction process, accompanied by oxidation regeneration sulfur evolution process, the analyzed sulfur can be separated in time, so that the reaction sulfur is proportional to the sulfur carried out, achieving material balance, bringing production into a virtuous cycle control, and pursuing high-energy, low consumption, long-term, safe and economic operation.

近幾年，隨著焦化技術的不斷進步，為了達到更好的脫硫效果，很多廠在實際運行中都有了一些變化。對于焦爐煤氣脫硫由一進口含量硫化氫含量很高，在脫硫工藝的設計上一般都設計成雙系統，即可并聯操作，又可串聯運行，雙脫硫塔并聯操作時，脫硫系統阻力小，單塔負荷低，不易堵塔；但脫硫效果不如雙塔串聯運行時高，考慮到焦爐煤氣入口硫化氫含量較高，脫硫裝置采用雙塔串聯運行方式。

In recent years, with the continuous progress of coking technology, in order to achieve better desulfurization effect, many plants have some changes in the actual operation. For the desulfurization of coke oven gas, the content of hydrogen sulfide in one inlet is very high. In the design of desulfurization process, it is generally designed as two systems, which can be operated in parallel or in series. When the two desulfurization towers are operated in parallel, the resistance of desulfurization system is small, the load of single tower is low, and it is not easy to block the tower; Considering the high content of hydrogen sulfide in the inlet of coke oven gas, the desulfurization device adopts double tower series operation mode.

隨著環保的重視，焦爐煤氣脫硫工藝的地位越來越高，希望通過不斷的優化調整，使整個系統能實現經濟、高能、長周期穩定運行。

With the attention of environmental protection, the status of coke oven gas desulfurization process is getting higher and higher. It is hoped that through continuous optimization and adjustment, the whole system can achieve economic, high-energy, long-term stable operation.
