Kurapa kwedu gasi remuswe remamiriyoni zana nemakumi maviri eNm3/d uye pasuru yedu yekudzoreredza LPG iri kushanda zvakanaka muguta reGuizou, China.
Kurapa kwegasi rechisikigo chikamu chakakosha cheindasitiri yegasi rechisikigo, chinangwa chekuderedza kuburitswa kwezvinhu zvinokuvadza mugasi rinoburitsa utsi, kuchengetedza nharaunda nehutano hwevanhu. Chigadzirwa chekuchenesa gasi rechisikigo chinoshandisa tekinoroji yepamusoro yekurapa gasi rekumashure kuona kuti zvinhu zvine chepfu uye zvinokuvadza mugasi rekumashure zvinosanganiswa zvizere zvisati zvaburitswa, kuitira kusangana nezvinodiwa zvekusvibisa uye kudzivirira kusvibiswa kwemhepo. Heano mamwe maitiro akakosha ekugadzirisa uye mashandisirwo ehunyanzvi.
Nheyo yekudzora uye kushandiswa kwechinhu chinopisira gasi remuswe: Mukugadzirisa gasi remuswe pamiti yekuchenesa gasi rechisikigo, chinhu chinopisira gasi remuswe chishandiso chakakosha, icho basa guru nderekuomesa zvachose zvinhu zvine chepfu uye zvinokuvadza zviri mugasi remuswe chisati chaburitswa. Nekutora matanho akatevedzana, akadai sekutsiva pfuti yekupisa nekuona murazvo wakanyanya, kuwedzera mwero wekuyerera kwegasi rekudzivirira kutonhora, uye kubvisa mhepo inobuda padivi pechinhu chinopisira gasi remuswe, hupenyu hwebasa hwechinhu chinopisira gasi remuswe hwavandudzika zvikuru, zvichiita kuti chishande zvakanaka chechinhu chinopisira gasi remuswe.
Chirongwa chekugadzirisa gasi remuswe: Kuti kuderedze kuburitswa kwezvinhu zvinokuvadza mugasi remuswe, Moxi Natural Gas Purification Plant yakaita chirongwa chekugadzirisa gasi remuswe reunit recovery. Chinangwa chechirongwa ichi ndechekuderedza huwandu hwegasi remuswe resulfur dioxide kubva mugasi reutsi uye kupa vimbiso yekuwanikwa kwegasi rechisikigo munguva yechando munharaunda iyi. Chirongwa ichi chakapedzwa uye chakatanga kushanda, zvichiratidza kukosha kwekuchengetedzwa kwezvakatipoteredza nehutano hweveruzhinji.
Kugadzira gasi rechisikigo inzira yekubvisa utsi hwemvura, hydrogen sulfide, mercaptan, uye carbon dioxide kubva mugasi rechisikigo. Midziyo mikuru inosanganisira chikamu chekubvisa mvura mumuviri, chikamu chekubvisa sulfurization, chikamu chekubvisa kabhoniuye kudzoreredzwa kwemahydrocarbon echiedza chikwata.
Kudzoreredza mahydrocarbon zvishoma zvinoreva maitiro ekudzorera zvikamu zvinorema zvegasi rechisikigo, zvakaita semethane kana ethane, muchimiro chemvura. Pakati pazvo, musanganiswa wepropane butane unova liquefied petroleum gas (LPG), uye pentane nezvimwe zviri pamusoro zvinova mafuta akareruka. Kudzoreredza mahydrocarbon zvishoma zvinowanzoshandisa kutonhora kwepropane uye kutonhora kwakasanganiswa kuti zviwane mashandiro akasiyana ekudzoka.
