Muchikamu chekuchenesa gasi rechisikigo, kune nzira nhatu dzakajairika dzekuchenesa, dzinoti nzira yealcohol amine, nzira yepotassium inopisa (benfied) uye nzira ye sulfonol amine.
Mercury: kuvapo kwemercury kunogona kukanganisa midziyo yearuminiyamu zvakanyanya. Kana Mercury (kusanganisira elemental mercury, mercury ions uye organic mercury compounds), aruminiyamu inosangana nemvura kugadzira zvigadzirwa zvehupfu hwakachena, izvo zvinokuvadza zvakanyanya hunhu hwearuminiyamu. Hunhu hushoma hwemercury hwakakwana kukonzera kukuvara kwakanyanya kumidziyo yearuminiyamu, uye Mercury inokonzerawo kusvibiswa kwezvakatipoteredza uye kukuvara kuvashandi panguva yekugadzirisa. Naizvozvo, huwandu hwemercury hunofanira kuganhurirwa zvakanyanya. Bvisa mercury Nheyo yacho yakavakirwa pakuita kwemercury nesarufa mu catalytic reactor.
Hydrocarbon inorema: zvinoreva mahydrocarbon ari pamusoro peC5+. Mumahydrocarbon, kana huremu hwemamorekuru huchichinja kubva padiki kuenda pakuru, poindi yayo yekufashaira inochinja kubva pakaderera kuenda pakakwirira. Nokudaro, mukutenderera kwekupfapfaidza gasi rechisikigo, mahydrocarbon anorema anogara achipfapfaidzwa kutanga. Kana hydrocarbon inorema isina kupatsanurwa kutanga, kana kupatsanurwa mushure mekupfapfaidzwa, hydrocarbon inorema inogona kuomesa nechando ndokuvhara michina. Mahydrocarbon anorema anobviswa zvishoma nesefa yemorekuru nezvimwe zvinonyungudutsa panguva yekushaya mvura, uye mamwe anoparadzaniswa nekupatsanurwa kwecryogenic.
Cos: inogona kunyoroveswa nemvura shoma kuti igadzire H2S neCO2, zvichikonzera ngura kumidziyo. Zviri nyore kusanganisa nepropane yakawanikwa. Inowanzo bviswa pamwe chete neH2S neCO2 panguva yekubvisa acidity.
Helium: gasi rechisikigo ndiro rinonyanya kuburitsa helium uye rinofanira kupatsanurwa uye kushandiswa. Rinoshandiswa zvakanyanya nekubatanidzwa kwekupatsanurwa kwemembrane uye kupatsanurwa kwecryogenic.
Nitrogen: kuwedzera kwehuwandu hwayo kuchaita kuti kunyungudika kwegasi rechisikigo kuve kwakaoma. Nzira yekupedzisira yeflash inowanzo shandiswa kubvisa kubva kuLNG.
Chinhu chikuru chegasi rechisikigo imethane (CH4), uye poindi yayo yekufashaira i111k (-162 ℃).
Kuwanda kwemethane yemvura panzvimbo inofashaira i426kg / m3, uye kuwanda kwemethane yegesi panzvimbo inofashaira i0.717kg / m3, ine musiyano wekanenge ka600. Musiyano mukuru muhuwandu ndicho chikonzero chikuru chekuchengetwa nekutakurwa kwegasi rechisikigo rakanyungudika.
