Khase ke lentsoe le akaretsang bakeng sa libeso tsa khase tse tukang le ho ntša mocheso bakeng sa ho sebelisoa ke baahi ba litoropo le likhoebo tsa indasteri. Ho na le mefuta e mengata ea khase, haholo-holo khase ea tlhaho, khase ea maiketsetso, khase ea petroleum e metsi le biogas.

Ho na le mefuta e 4 ea khase e tloaelehileng ea toropo: Khase ea Tlhaho, Khase ea Maiketsetso, Liquefied Petroleum Gas, Substitute Natural Gas.

1. Liquefied Petroleum Gas:

LPG e hlahisoa haholo-holo ho tloha lihlahisoa tsa oli nakong ea ts'ebetso ea ho phunyeha ha oli, likarolo tsa eona tse ka sehloohong ke propane le butane, tse nang le propylene le butene tse nyenyane.

2. Sebaka sa Khase ea Tlhaho:

LPG e futhumatsoa 'me e fetoha boemo ba khase ka lisebelisoa tse khethehileng,' me ka nako e ts'oanang moea o mongata (hoo e ka bang 50%) o kopanngoa ho atolosa molumo oa oona, ho fokotsa mahloriso a oona le ho fokotsa boleng ba lik'halori e le hore o ka fuoa khase ea tlhaho.

3. Khase ea Maiketsetso:

Likhase tse entsoeng ka mafura a tiileng a kang mashala le coke kapa mafura a metsi a kang oli e boima ka mekhoa e kang distillation e omileng, vaporization kapa cracking, eo likarolo tsa eona tsa sehlooho e leng hydrogen, nitrogen, carbon monoxide le carbon dioxide.

4. Khase ea Tlhaho:

Khase ea tlhaho e tukang e teng ka tlas'a lefatše e bitsoa khase ea tlhaho 'me haholo-holo e entsoe ka methane, empa hape e na le ethane e nyenyane, butane, pentane, carbon dioxide, carbon monoxide, hydrogen sulfide, joalo-joalo.

Ho na le mefuta e mehlano ea khase ea tlhaho, ho itšetlehile ka hore na e thehoa le ho ntšoa joang:

1. Khase e hloekileng ea tlhaho: Khase ea tlhaho e ntšoa masimong a ka tlas’a lefatše.

2. Khase e Amanang le Oli: Mofuta ona oa khase o ntšoa sekotong sa oli o bitsoa khase e amanang le oli.

3. Khase ea morafo: Khase ea morafo e bokelloa nakong ea merafo ea mashala.

4. Condensate field gas: Khase e nang le likaroloana tse bobebe tsa petroleum.

5. Coalbed methane Gas Mine: E ntšoa ka tlas'a lefatše seam ea mashala

Ha o tsamaisa khase,li-valve tsa bolo ea lipeipi tsa khaseli sebelisetsoa ho laola liteishene tsa liheke tsa khase, ha li ntse lili-valve tsa metha ea khaseli sebelisetsoa ho laola khase ea ntlo.
