Zeolite molecular sieves gaw shingra wan hpe galaw shapraw ai hta ahkyak ai lit nga ai, ahkyak ai san seng ai magam bungli ni hpe (hka n-gun yawm mat ai, n-gun yawm mat ai, decarbonization zawn re ai) hpe lata la ai adsorption hku nna galaw ai, dai majaw shingra wan a hkamja lam hpe grau kaja hkra galaw ya nna, shim lum ai hku htaw sa lu na matu galaw ya lu ai.
Shingra wan hka n-gun yawm mat ai
Natural gas hpe hka n-gun hte shapraw ai rai nna, hka n-gun loi mi hpe pyi htaw sa ai. Natural gas hta hka nga ai gaw grai n kaja ai lam langai rai nna, dai gaw natural gas hpe hka n-gun yawm mat hkra galaw ra ai lam byin shangun nga ai. Ga shadawn:
Hka hte methane gaw hka - zawn re ai solid hydrates ni hpe n-gun n law ai hte n-gun kaba ai npu hta byin shangun ai (pipeline htaw sa ai lam (sh) hka lim ai lam hta zawn re ai), dai gaw valve, pipeline, hte arung arai ni hpe pat kau ya nna, htaw sa ai lam hpe pat shingdang kau ya lu ai.
Hka gaw shingra wan hta lawm ai hydrogen sulfide (sh) carbon dioxide hte shingdaw nna, acid rawng ai arung arai ni (sulfuric acid, carbonic acid) hpe shapraw ya ai majaw, magri pipe ni hte jak ni a n-gun hpe lawan ladan hten za shangun nna, shanhte a bungli galaw ai aten hpe kadun shangun ai.
Shingra wan hpe sung sung katsi shangun ra ai shaloi, liquefied shingra wan (LNG) hpe -162℃du hkra katsi shangun ra ai zawn, ngam nga ai hka gaw katsi mat nna, cryogenic heat exchangers zawn re ai ahkyak ai arung arai ni hpe jahten kau na re.
Molecular sieves ni gaw, shanhte a pore size langai sha re ai majaw, hka molecule ni hpe grau ra sharawng ai hku hkap la lu ai.

Shingra wan sau hpe galaw shapraw na matu Zeolite Molecular Sieves ni
Type 3A zeolite molecular sieve: Shi a n-gup magap kaba ai gaw 3Å rai nna, madung hku nna 2.8Å daram galu ai hka molecule ni hpe hkap la na matu lang ai. Shi gaw shingra wan kaw na hka hpe atsawm sha shapraw kau lu ai sha n-ga, hydrocarbon ni hpe n hkap la ai sha, shingra wan hpe hka n-gun yawm mat hkra galaw na matu htuk manu ai.
4A amyu zeolite molecule sieve: Shi a n-gup magap kaba ai gaw 4Å rai nna, hka molecule ni hpe lata la nna hkap la lu ai (diameter 2.8Å).
