10~30 ×10⁴Nm³/d Kunyungudutsa kweLNG hombe

Nhanganyaya

Gasi rechisikigo rinonyungudutsa mvura, rinonzi LNG, rinoita kuti gasi rechisikigo rive mvura nekutonhodza gasi rechisikigo rinonyungudutsa mvura pasi pekumanikidzwa kwakajairika kusvika ku -162 ℃. Kunyungudutsa mvura muchisikigo kunogona kuchengetedza nzvimbo yekuchengetera nekufambisa, uye kune mabhenefiti ekuva nemafuta akawanda, kushanda kwepamusoro, kunobatsira pakuyera mutoro wemaguta, kunobatsira pakuchengetedzwa kwezvakatipoteredza, kuderedza kusvibiswa kwemaguta nezvimwewo.

Kunyungudutsa mvura ndiyo musimboti wekugadzirwa kweLNG uye fekitari yeLNG yakasungirirwa pasd. Parizvino, maitiro ekugadzira mvura negasi rechisikigo anosanganisira maitiro ekugadzira mvura necascade, maitiro ekugadzira mvura nefiriji yakasanganiswa uye maitiro ekugadzira mvura neexpander.

Maitiro ekunyungudutsa gasi rechisikigo anoshandisa mapoinzi akasiyana-siyana ekufashaira mufiriji pasi pekumanikidzwa kwakajairika kuderedza tembiricha yekutonhodza nhanho nhanho kuti azadzise chinangwa chekunyungudutsa gasi rechisikigo.

Mixed refrigerant cycle (MRC) inzira iyo mafiriji anodarika mashanu ane zvikamu zvakawanda, akadai seC1 ~ C5 Hydrocarbons neN2, anoshandiswa semvura inoshanda kuomesa, kupwanya uye kuwedzera nhanho nhanho kuti awane kugona kutonhora pamazinga akasiyana ekupisa, uye ozotonhodza zvishoma nezvishoma uye kunyungudutsa gasi rechisikigo. Maitiro ekudzikisa mvura mufiriji akakamurwa kuita mhando dzakasiyana dzemafiriji.

Maitiro ekunyungudutsa mvura ne expander zvinoreva maitiro ekunyungudutsa mvura negasi rechisikigo nekushandisa refrigerant ine pressure yakakwira kuti iite reverse Claude cycle refrigerator nekuwedzera adiabatic kwe turbo expander.

Chirongwa chemaitiro acho chinosanganisira: feed gas regulating and metering unit, natural gas cleansing unit uye natural gas liquefaction unit, refrigerant storage system, refrigerant circulating compression system, LNG storage and loading unit.

Kuti tigadzire LNG Plant Skid, tinoda parameter inotevera.

1) Mamiriro ekutanga ekugadzirwa kwemiti:

Kuyerera kwegasi rinodyisa

Kumanikidzwa kwegasi rekudya

Tembiricha yegesi yekudya

Mvura yakasununguka mugasi rekudya

2） Yakadzama chikafu gasi muchimiro (mole%)

3) Zvigadzirwa zvechigadzirwa:

Gasi rechisikigo rakanyungudika:

Kumanikidzwa kwekunze

Kupisa kwepasi pemvura pasi pekumanikidzwa kwekunze

nitrogen yakawanda
