沼氣濕法脫硫888法的技術(shù)特點
Technical characteristics of methane wet desulfurization 888 method
濕式氧化法脫硫的工藝流程中加入888脫硫催化劑后就稱為888法脫硫。888法的特點與888脫硫催化劑的特點是不相同的，比如“888”本身不脫硫，不存在工作硫容，但把“888”加入到弱堿溶液中組成脫硫循環(huán)液后，脫硫運作時，就存在工作硫容。
The process flow of wet oxidation desulfurization is called 888 desulfurization after 888 desulfurization catalyst is added. The characteristics of 888 method are different from those of 888 desulfurization catalyst. For example, "888" itself does not desulfurization and does not have working sulfur capacity. However, after "888" is added to weak alkali solution to form desulfurization circulating liquid, there will be working sulfur capacity during desulfurization operation.
可以歸納為888法的特點有十個。
It can be concluded that there are ten characteristics of 888 method.
1、工作硫容高，脫硫效率高
1. High working sulfur capacity and high desulfurization efficiency
2、具有**和解決硫磺堵塔的功能
2. It has the function of * * and solving sulfur tower blockage
3、具有脫有*硫的功能，脫硫率為50%到80%
3. It has the function of removing sulfur, and the desulfurization rate is 50% to 80%
4、有脫高硫氣的功能
4. It has the function of removing high sulfur gas
5、副反應(yīng)生成率低，純堿消耗低，硫回收率高，脫硫費用低
5. The side reaction generation rate is low, the consumption of soda ash is low, the sulfur recovery rate is high, and the desulfurization cost is low
一般副反應(yīng)生成率在3%以下，有些廠應(yīng)用“888” 后，溶液中Na2S2O3含量還出現(xiàn)下降值。6、溶液組成簡單，管理與操作方便
Generally, the generation rate of side reaction is less than 3%. After the application of "888" in some plants, the content of Na2S2O3 in the solution also decreases. 6. The solution has simple composition and convenient management and operation
脫硫液除了吸收劑外，脫硫催化劑只有一種即“888”。 所以溶液組份對脫硫過程的影響因素單純，容易調(diào)節(jié)。
In addition to absorbent, there is only one desulfurization catalyst, namely "888". Therefore, the influence factors of solution components on desulfurization process are simple and easy to adjust.
7、催化劑活*好，用量少，消耗低，運行經(jīng)濟(jì)
7. Good catalyst activity, less consumption, low consumption and economic operation
通常情況下每脫除1kg HS需耗“888”0.5-0.9克，有些比這個數(shù)還要低。
Generally, 0.5-0.9g of "888" is required to remove 1kg of HS, some of which are lower than this number.
8、貧液懸浮硫低，溶液清亮有利于節(jié)能
8. Low suspended sulfur in lean solution and clear solution are conducive to energy saving
9、應(yīng)用范圍廣
9. Wide application range
可應(yīng)用半水煤氣、富氧氣化的煤氣、甲醇原料氣、變換氣、焦?fàn)t氣、城市煤氣、
Semi water gas, oxygen enriched gasification gas, methanol feed gas, shift gas, coke oven gas, city gas
沼氣等含硫氣體的脫硫；加壓、常壓脫硫均可以應(yīng)用。
Desulfurization of sulfur-containing biogas; Pressurized and atmospheric desulfurization can be applied.
