1  Pfupiso yeSisitimu

Gasi rinodyisa rinopinda mugadziriro yekurapa gasi rechisikigo mushure mekusefa, kupatsanurwa, kudzorwa kwedzvinyiriro uye kuyerwa. Mushure mekubvisa CO2, gasi rinodyisa rinopinda mugadziriro yekurapa gasi rechisikigo mushure mekusefa, kupatsanurwa, kudzorwa kwedzvinyiriro uye kuyerwa.₂, H₂O, mahydrocarbon anorema neHg, inopinda mubhokisi rinotonhora remvura inotonhorera, yotonhodzwa, yonyungudika, yotonhodzwa zvishoma nezvishoma uye yoiswa muchina wekupisa weplate-fin. Zvadaro inopinda mutangi rekuchengetera LNG sechigadzirwa cheLNG.

Nzira huru dzetekinoroji dzechishandiso ichi ndeidzi:

• Shandisa MDEA kubvisa kabhoni dioksijeni;

• Masefa emamorekuru anoshandiswa kubvisa mvurar
• Shandisa kabhoni yakakangwa kubvisa mahydrocarbon anorema;

• Shandisa kabhoni yakasanganiswa nesarufa kubvisa mercury;

• Shandisa zvinhu zvinonyatso shandiswa pakusefa molecular sefa neguruva rekabhoni rakashandiswa;

• Gasi rechisikigo rese rakacheneswa rinonyungudutswa nemvura neMRC (mixed refrigerant) inotenderera mufiriji;

  Iyi sisitimu yemaitiro inosanganisira:

• Kusefa nekuparadzanisa gasi rekudyisa, mutemo wekumanikidzwa uye sisitimu yekuyera;

• Nzira yekurapa isati yatanga (kusanganisira kubvisa kabhoni mumhepo, kushaya mvura mumuviri, kubviswa kwemahydrocarbon akawanda, kubviswa kwemercury, uye kubviswa kweguruva);

• Sisitimu yekuyera MR uye sisitimu yekutenderera kwekumanikidza kweMR;

• Sisitimu yekunyungudutsa mvura yeLNG;

• Sisitimu yekudzokorodza yeBOG

2   Tsananguro yehurongwa hwega hwega

2.1      Kupatsanurana kwemafuta egasi uye kudzvinyirira kunodzora chikamu

1) Tsananguro yemaitiro

Gasi rinobuda mumhepo rinobva kumusoro kwerwizi rinodzorwa nekumanikidzwa uye robva rapinda muchikamu chinoparadzanisa firita rinopinda mumhepo, uye robva rapinda musystem iri pasi pemvura mushure mekumanikidzwa, kupatsanurwa uye kuyerwa.

Midziyo yayo mikuru yekugadzira zvinhu ndeyekuparadzanisa firita yegesi, flow meter, compressor nezvimwewo.

2) Magadzirirwo edhizaini

Kugona kubata: 10×10 ⁴ Nm ³ /zuva

Rudzi rwekugadzirisa: 50% ~ 110%

Kumanikidzwa kwemhepo inoburitsa compressor: 5. 2Mpa.g

2.2      Chigadziko chekubvisa asidhi yegesi inodyisa

1) Tsananguro yemaitiro

Gasi rinobuda murwizi rwunobuda richipinda muchikamu chekubvisa acid, uye chikamu ichi chinoshandisa nzira yeMDEA solution yekubvisa magasi ane acid akadai seCO2.₂ uye H₂S mugasi rinopa simba.

Gasi rechisikigo rinopinda kubva pasi peshongwe yekunyudza uye rinopfuura nepashongwe yekunyudza kubva pasi kuenda kumusoro; mhinduro yeMDEA yakagadziriswazve zvizere (mvura isina kusimba) inopinda kubva pamusoro peshongwe yekunyudza, inopfuura nepashongwe yekunyudza kubva kumusoro kuenda pasi, uye mhinduro yeMDEA negasi rechisikigo rinoyerera nenzira yakatarisana zviri mushongwe yekunyudza Kana zvasvika zvakazara, CO2₂ mugasi _iri inonyudzwa muchikamu chemvura, uye zvikamu zvisina kunyudzwa zvinoburitswa kubva pamusoro peshongwe yekunyudzwa uye zvinopinda muchinhu chinotonhorera gasi chakabviswa kabhoni uye chinoparadzanisa. Gasi rinobuda muchikamu chinoparadzanisa gasi chakabviswa kabhoni rinopinda muchikamu chinobvisa mercury gas feed, uye condensate inoenda kuflash tank.

CO₂ huwandu hwemvura inorapwa mumuviri wemunhu husingasviki 50ppmv.

MEDA yakatora CO2₂ inonzi mvura yakapfuma, uye inotumirwa kuflash tower, uye gasi rechisikigo rinobuda pasi pekuderedza kumanikidzwa rinotumirwa kusystem yemafuta. Mushure mekupenya, mvura yakapfuma inochinjana kupisa nemushonga (mvura yakakora) inoyerera ichibva pasi peshongwe yekuvandudza, uye tembiricha inokwidzwa kusvika ~98 °C kuenda kuchikamu chepamusoro cheshongwe yekudzoreredza.

Mvura isina kusimba inobva mushongwe yekudzoreredza inopfuura nemuchinochinja-chinja kupisa kwemvura ine mvura yakawanda uye muchinotonhodza mvura isina kusimba, mvura isina kusimba inotonhodzwa kusvika ~40 ℃, uye mushure mekumanikidzwa nepombi yemvura isina kusimba, inopinda ichibva kumusoro kweshongwe yekunyudza.

Gasi riri pamusoro penzvimbo yekubuditsa mweya we regeneration tower rinopfuura nepamuchina wekutonhodza mweya we acid gas ropinda mu acid gas separator. Gasi rinobva mu acid gas separator rinotumirwa ku acid gas discharge system, uye condensate inomanikidzwa nepombi yekudzoreredza mweya wozotumirwa ku flash separator.

Nzvimbo inodziya ye reboiler ye regeneration tower inodziiswa nemafuta e heat transfer.

Midziyo mikuru yemuchina uyu ishongwe yekunyudza uye shongwe yekudzoreredza.

2) Magadzirirwo edhizaini

Kugona kubata: 10×10 ⁴ Nm ³ /zuva

Gasi rekudya CO₂ poindi yekugadzira: 3%

Kumanikidzwa kwekushanda kweshongwe yekunyudza: 5Mpa.G

Tembiricha yekushanda kweshongwe yekunyudza: 40 ℃ ~ 60 ℃

Nhare yekuvandudza: 0.03 Mpa.G~0.05 Mpa.G

Kushandiswa kweshongwe yekuvandudza denga: 95 ℃ ~ 120 ℃

Kupisa kunodzoreredza: kupisa kuchinjisa mafuta kupisa

CO₂ gasi riri mugasi rakabviswa kabhoni riri ≤50ppm
