Biogas shine gas mai ƙonewa wanda abubuwan halitta ke samarwa ta hanyar narkewar anaerobic. Halayensa suna kama da gas, kyakkyawan mai tsabta ne, kuma makamashi ne mai sabuntawa. Amma abun ciki na hydrogen sulfide (H2S) da ke cikin biogas yana da ƙarfin lalata, yana lalata kayan aikin ƙasa yayin amfani, kuma yana fitar da sulfur oxide yayin konewa, yana haifar da gurɓataccen muhalli, saboda haka yana iyakance amfani da biogas sosai.

Me ya sa za a desulfurize biogas?

A lokacin aikin narkewa na anaerobic, ana canza mahada masu dauke da sulfur zuwa H2S, kuma yawanci, abun ciki na H2S a cikin biogas yana tsakanin 0.1-0.2%. H2S yana da ƙarfin lalata, ba kawai zai haifar da lalata na bututun, bawul, ma'aunin kwarara ba, lalacewar injin ƙonawa na ciki tana da girma sosai. Bayan ƙonawa, H2S ya samar da sulfuric acid, yana rage sauyawar injin man fetur, yana rage rayuwar aikin kayan aiki, yana ƙara kuɗin gyaran kayan aiki, sauyawa da kulawa. A lokaci guda, bayan ƙonawa na H2S yana haifar da gurɓataccen yanayi. Cire H2S daga biogas ta hanyar amfani da hanyoyin halitta masu aminci ba kawai yana tabbatar da aikin kayan aikinka na dogon lokaci da inganci ba, amma mafi mahimmanci yana haɓaka inganci don adana lokaci da kuɗi.
