Lits'ebetsong tsa biogas desulfurization, marang-rang a marang-rang a marang-rang a bapala karolo ea bohlokoa ka ho ntlafatsa ts'ebetso, polokeho, le ho latela tikoloho. Lisebelisoa tsa bona tsa bohlokoa ke tsena:
- Tlhokomelo ea Mokelikeli oa Mokelikeli oa Desulfurization
Ka biogas desulfurization e metsi, tharollo ea alkaline e sebelisoa ho tlosa hydrogen sulfide (H₂S) ka ho kopana le countercurrent. Bongata ba mokelikeli oa desulfurization bo tsamaellana le letsoalo la lona, leo limithara tsa marang-rang li ka li shebellang ka nako ea nnete.

Leha haholo-holo li-flow metres tsa Coriolis, li ka boela tsa lekanya boima ba 'mele ka ho nepahala ho phahameng lits'ebetsong tse kenyelletsang maro a nang le matla a fapaneng. Li ka tšeptjoa bakeng sa biogas desulfurization moo taolo e nepahetseng ea karabelo ea lik'hemik'hale e bohlokoa.
Tharollo bakeng sa biogas desulfurization e lokela ho totobatsa karolo ea bohlokoa ea liindasteri le taolo e nepahetseng ho ntlafatsa ts'ebetso. Ka ho kenya ts'ebetsong lisebelisoa tsa ho lekola nako ea 'nete, joalo ka li-inline density metres, liindasteri li khona ho laola ka nepo likhahla tsa metsi a desulfurization ho netefatsa ts'ebetso e phahameng le botsitso ba sistimi. Sena ha se thibele feela ho bola ha lisebelisoa le litšitiso empa hape se fokotsa litšenyehelo tsa ts'ebetso le ho matlafatsa boitlamo ba tikoloho ka ho fokotsa mesi e kotsi joalo ka hydrogen sulfide.
Ho feta moo, ho iketsetsa ts'ebetso ea desulfurization ho fokotsa haholo matla a mosebetsi, ho eketsa polokeho, le ho netefatsa ts'ebetso e tsoelang pele, e tšepahalang. Taolo e nepahetseng ea mokelikeli oa desulfurization e thusa ho hlophisa hantle maemo a karabelo, qetellong ea ntlafatsa tšebeliso ea matla le boleng ba biogas. Likhatelo-pele tsena li bontša tsoelo-pele ea mekhoa e tsitsitseng ea indasteri, e ikamahanyang le lipakane tsa sejoale-joale tsa matla le tlhokomelo ea tikoloho.
