Biogas zuwa CNG/LNG Shuka

Biogas zuwa CNG/LNG Bayanin

Ta hanyar jerin jiyya na tsarkakewa irin su desulfurization, decarbonization da dehydration na biogas, ana iya samar da iskar gas mai tsabta da gurɓataccen gurɓataccen iska, wanda ke ƙara ƙimar ƙimar kuzari. Gas ɗin wutsiya da aka lalatar kuma na iya samar da ruwa carbon dioxide, ta yadda za a iya amfani da iskar gas gabaɗaya kuma yadda ya kamata, kuma ba zai haifar da gurɓataccen gurɓataccen abu ba.

Dangane da bukatun samfurin ƙarshe, ana iya samar da iskar gas daga iskar gas, wanda za'a iya kai shi kai tsaye zuwa cibiyar sadarwar bututun iskar gas a matsayin iskar gas; Ko CNG (dankakken iskar gas don ababen hawa) ana iya yin shi azaman man abin hawa ta hanyar matsa iskar gas zuwa 20 ~ 25MPa; Hakanan yana yiwuwa a sanya iskar gas ɗin da ake kira cryogenically kuma a ƙarshe samar da LNG (gas ɗin da aka ɗora).

Tsarin biogas zuwa CNG shine ainihin jerin hanyoyin tsarkakewa da tsarin matsi na ƙarshe.
1. Babban abun ciki na sulfur zai lalata kayan aiki da bututu kuma ya rage rayuwar sabis;
2. Mafi girman adadin CO₂, ƙananan ƙimar calorific na gas;
3. Tunda ana samar da iskar gas a cikin yanayin anaerobic, O₂abun ciki ba zai wuce ma'auni ba, amma ya kamata a lura cewa O₂abun ciki kada ya zama sama da 0.5% bayan tsarkakewa.
4. A cikin aikin jigilar bututun iskar gas, ruwa yana taruwa cikin ruwa a cikin ƙananan zafin jiki, wanda zai rage ƙetare yanki na bututun, ƙara juriya da amfani da makamashi a cikin tsarin sufuri, har ma daskarewa da toshe bututun; Bugu da ƙari, kasancewar ruwa zai hanzarta lalata sulfide akan kayan aiki.

Bisa ga dacewa sigogi na raw biogas da bincike na samfurin bukatun, raw biogas iya zama nasara desulfurization, pressurization bushewa, decarbonization, CNG pressurization da sauran matakai, da samfurin za a iya samu: matsa CNG ga abin hawa.
