Khetho ea mokhoa oa ho hloekisa khase ea tlhaho
Khase ea tlhaho e le khase ea phepelo e lokela ho hloekisoa hantle pele e tšeloa. Ke hore, tlosa khase ea asiti, metsi le litšila tse ka har'a khase ea phepelo, joalo ka H2S, CO2, H2O, Hg le di-hydrocarbon tse nkhang hamonate, e le ho di thibela ho hatsela mochesong o tlase le ho thibela le ho senya disebediswa le diphaephe.
A) Tafole ea 1-1 e thathamisa maemo a pele ho kalafo a khase ea phepelo fekthering ea LNG le litaba tse phahameng ka ho fetisisa tsa litšila.
Tafole ea 1-1 tekanyo e phahameng ka ho fetisisa ea litšila tse lumelletsoeng tsa khase ea phepelo ea LNG
| Litšila | Moeli oa litaba | Motheo |
| H2THE | 1ppmV | A (e lumelloa ho feta moedi wa ho qhalwa ntle le ho fokotsa tlhahiso) |

Boteng ba metsi ka hara khase ea tlhaho hangata bo lebisa liphellong tse tebileng: tlas'a maemo a itseng, metsi le khase ea tlhaho li theha hydrate ho thibela phaephe le ho ama ts'ebetso ea ho pholisa metsi a metsi; Ho phaella moo, boteng ba metsi bo tla boela bo bake tšebeliso e sa hlokahaleng ea matla; Ka lebaka la mocheso o tlase oa metsi a metsi a khase ea tlhaho le boteng ba metsi, lisebelisoa li tla hoamisoa le ho koaloa, kahoo li tlameha ho omisoa.
Mokhoa oa ho felloa ke metsi ha khase ea tlhaho ka kakaretso e kenyelletsa mekhahlelo e meraro: ho felloa ke metsi mochesong o tlase, ho monngoa ha desiccant e tiileng le ho monngoa ha solvent. Karohano ea ho hoamisa e sebelisoa haholo-holo ho qoba hydrate ha mocheso oa khase ea tlhaho o le tlase. Leha ho le joalo, mocheso o tlase oo e o lumellang o lekanyelitsoe 'me o ke ke oa fihlela litlhoko tsa ho qhibiliha ha khase ea tlhaho; Ho monngoa ha solvent hangata ho kenyelletsa asiti e kopaneng (hangata asiti ea organic joalo ka phosphoric acid e kopaneng), glycol (triethylene glycol e sebelisoang hangata), jj., empa mekhoa ena e na le botebo bo tlase ba ho felloa ke metsi 'me e ke ke ea sebelisoa liyuniting tsa cryogenic; Mekhoa e tloaelehileng ea ho felloa ke metsi mochesong oa desiccant e tiileng ke mokhoa oa silica gel, mokhoa oa sefe ea limolek'hule kapa motsoako oa mekhoa ena e 'meli.

C) Khetho ea mokhoa oa ho tlosa mercury
Hona jwale, ho na le mekgwa e mmedi e meholo ya ho tlosa mercury: mokgwa wa ho tlosa mercury ka ho sebedisa sefa ya hgsiv ya k'hamphani ya UOP United States le sebabole se kentsweng khabone e sebetsang ho etsa hore mercury e arabele ka sebabole ho hlahisa mercury sulfide le ho e monya khaboneng e sebetsang. Ya pele e na le ditjeo tse hodimo mme e loketse diketsahalong tse nang le ditjeo tse hodimo tsa mercury; Ya morao e na le ditjeo tse tlase tsa tshebetso mme e loketse diketsahalong tse nang le ditjeo tse tlase tsa mercury.
Ka lehlakoreng le leng, litšenyehelo tsa ts'ebetso ea sefe ea limolek'hule ea hgsiv li phahame haholo; Ka lehlakoreng le leng, litaba tsa mercury khaseng ea phepelo ea yuniti li tlase haholo. Ka hona, k'hamphani e na le boiphihlelo bo atlehileng ba ho sebelisa khabone e entsoeng ka sebabole e kenngoeng bakeng sa ho tlosa mercury.
