High Quality China Yakakura LNG Liquefaction Factory - 10~30 ×104Nm3/d Hombe LNG Liquefaction - Rongteng

Nhanganyaya

Liquefaction gasi rechisikigo, richangodaidzwa kuti LNG, riri kudzoreredza gasi rechisikigo kuita mvura nekutonhodza gasi rine gasi rechisikigo pasi pekumanikidzwa kwakajairika kusvika - 162 ℃. Natural gasi liquefaction inogona kuchengetedza zvakanyanya kuchengetedza uye nzvimbo yekufambisa, uye ine zvakanakira hombe calorific kukosha, kushanda kwepamusoro, kunobatsira kuenzana kwekutonga kwemutoro wemaguta, kunobatsira kuchengetedza kwezvakatipoteredza, kuderedza kusvibiswa kwemaguta uye zvichingodaro.

Liquefaction ndiyo musimboti weLNG kugadzirwa uye skid yakaiswa LNG chirimwa. Parizvino, iwo akakura echisikigo gasi liquefaction maitiro anonyanya kusanganisira cascade liquefaction process, yakasanganiswa refrigerant liquefaction process uye liquefaction process ine expander.

Cascade natural gasi liquefaction process inoshandisa akasiyana mafiriji mapoinzi efiriji pasi pekumanikidzwa kwakajairwa kudzikisa tembiricha yefiriji nhanho nhanho kuzadzisa chinangwa chegasi rechisikigo liquefaction.

Mixed refrigerant cycle (MRC) inzira umo marudzi anopfuura mashanu emafiriji akavhenganiswa akawanda, akadai seC1 ~ C5 Hydrocarbons neN2, anoshandiswa semvura inoshanda kudzikamisa, kubuda uye kuwedzera nhanho nhanho kuwana firiji inokwana patembiricha dzakasiyana, uyezve zvishoma nezvishoma kutonhora nekunyungudutsa gasi rechisikigo. Yakasanganiswa refrigerant liquefaction process yakakamurwa kuva akawanda akasiyana marudzi efiriji kutenderera.

Iyo liquefaction process ine expander inoreva maitiro ekunyungudika kwegasi echisikigo nekushandisa yakanyanya kudzvanywa refrigerant kuona reverse Claude kutenderera firiji ine adiabatic kuwedzera kweturbo expander.

Iyo process scheme inonyanya kusanganisira: yekudyisa gasi kudzvanywa inodzora uye metering unit, yakasikwa gasi yekuchenesa unit uye yakasikwa gasi liquefaction unit, refrigerant yekuchengetedza system, refrigerant inotenderera compression system, LNG kuchengetedza uye kurodha unit.

Dhizaini parameter

Kugadzira aLNG Plant Skid, tinoda iyo inotevera parameter.

1) Basic mamiriro ekugadzirwa kwechirimwa:

Kudyisa gasi kuyerera

Kudyisa gasi pressure

Feed gasi tembiricha

Mvura yemahara yegasi yekudya

2) Yakadzama gasi kuumbwa (mole%)

3) Product specifications:

Liquefied natural gas:

Outlet pressure

Subcooling tembiricha pasi pekubuda kwekumanikidza

Maximum nitrogen content

Maximum carbon dioxide content
