焦?fàn)t煤氣是寶貴的資源，作為工業(yè)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(zhuǎn)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(zhì)，硫化氫具有很強的腐蝕性，焦?fàn)t煤氣若不脫除硫化氫會嚴(yán)重腐蝕設(shè)備，作為民用燃料會污染環(huán)境，損害人們身體健康；下面讓我們來了解一下有關(guān)煤氣脫硫工藝的相關(guān)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?fàn)t煤氣脫硫工藝，經(jīng)過幾十年的發(fā)展形成了一些傳統(tǒng)流程，該流程簡單，易操作，生產(chǎn)穩(wěn)定，在焦化生產(chǎn)中發(fā)揮了重要作用；焦?fàn)t煤氣脫硫，有其特殊性，從工藝上講，在脫硫反應(yīng)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(yīng)成硫與帶出的硫成正比，達到物料平衡，將生產(chǎn)納入良性循環(huán)的控制，追求高能、低耗、長周期、安全、經(jīng)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(shù)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?fàn)t煤氣脫硫由一進口含量硫化氫含量很高，在脫硫工藝的設(shè)計上一般都設(shè)計成雙系統(tǒng)，即可并聯(lián)操作，又可串聯(lián)運行，雙脫硫塔并聯(lián)操作時，脫硫系統(tǒng)阻力小，單塔負(fù)荷低，不易堵塔；但脫硫效果不如雙塔串聯(lián)運行時高，考慮到焦?fàn)t煤氣入口硫化氫含量較高，脫硫裝置采用雙塔串聯(lián)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(huán)保的重視，焦?fàn)t煤氣脫硫工藝的地位越來越高，希望通過不斷的優(yōu)化調(diào)整，使整個系統(tǒng)能實現(xiàn)經(jīng)濟、高能、長周期穩(wěn)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.
