1  Isishwankathelo seNkqubo

Igesi yokufunxa ingena kwinkqubo yonyango lwegesi yendalo emva kokuba ihluziwe, yahlulwe, ilawulwa uxinzelelo kwaye ilinganiswe. Emva kokususa i-CO2₂, H₂O, iihydrocarbons ezinzima kunye neHg, ingena kwibhokisi ebandayo yolwelo, ize ipholiswe, inyibilikiswe, ipholiswe ngaphantsi kwaye igxojwe kwi-plate-fin heat exchanger. Emva koko ingena kwitanki yokugcina i-LNG njengemveliso ye-LNG.

Iindlela eziphambili zobuchwepheshe zesi sixhobo zezi:

• Sebenzisa i-MDEA ukususa i-carbon dioxide;

• Ii-molecular seefs zisetyenziselwa ukususa amanzir
• Sebenzisa ikhabhoni esebenzayo ukususa iihydrocarbon ezinzima;

• Sebenzisa ikhabhoni esebenzayo efakwe kwi-sulfur ukususa i-mercury;

• Sebenzisa izinto zesihluzo esichanekileyo ukuze uhluze isihluzo semolekyuli kunye nothuli lwekhabhoni olusebenzayo;

• Yonke igesi yendalo ecociweyo inyibilikiswa yinkqubo yokufriji ejikelezayo ye-MRC (mixed refrigerant);

  Le nkqubo ibandakanya:

• Ukuhluzwa kunye nokwahlulwa kwegesi yokutya, ulawulo loxinzelelo kunye nenkqubo yokulinganisa;

• Inkqubo yonyango lwangaphambi konyango (kubandakanya ukususwa kwekhabhoni, ukuphelelwa ngamanzi emzimbeni, ukususwa kweehydrocarbon ezininzi, ukususwa kwemercury, kunye nokususwa kothuli);

• Inkqubo yokulinganisa i-MR kunye nenkqubo yomjikelo woxinzelelo lwe-MR;

• Inkqubo yokunyibilikisa ulwelo lwe-LNG;

• Inkqubo yokuphinda usebenzise i-BOG

2   Inkcazo yenkqubo nganye

2.1      Ukwahlulahlula ukuhluzwa kwegesi kunye neyunithi yokulawula uxinzelelo

1) Inkcazo yenkqubo

Igesi yokufunxa evela kumsinga ophezulu ilawulwa ngoxinzelelo ize ingene kwisihluzi sokufaka igesi yokufunxa, ize ingene kwinkqubo esezantsi emva kokuba icinezelwe, yahlulwe kwaye ilinganiswe.

Izixhobo zayo eziphambili zenkqubo yi-feed gas filter separator, i-flow meter, i-compressor njalo njalo.

2) Iiparamitha zoyilo

Umthamo wokuphatha: 10×10 ⁴ Nm ³ /usuku

Uluhlu lohlengahlengiso: 50% ~ 110%

Uxinzelelo lwe-outlet ye-compressor: 5. 2Mpa.g

2.2      Iyunithi yokukhupha iasidi kwigesi yokutya

1) Inkcazo yenkqubo

Igesi yokutya evela kumsinga ongasentla ingena kwiyunithi yokususa i-asidi, kwaye le yunithi isebenzisa indlela yesisombululo se-MDEA ukususa iigesi ze-asidi ezifana ne-CO2₂ kunye no-H₂S kwigesi yokutya.

Igesi yendalo ingena isuka kwinxalenye esezantsi yenqaba yokufunxa kwaye idlule kwinqaba yokufunxa ukusuka ezantsi ukuya phezulu; isisombululo se-MDEA esihlaziyiweyo ngokupheleleyo (ulwelo olungenamthungo) singena sisuka kwinxalenye ephezulu yenqaba yokufunxa, sidlula kwinqaba yokufunxa ukusuka phezulu ukuya ezantsi, kwaye isisombululo se-MDEA kunye negesi yendalo ehamba kwicala elichaseneyo zikwinqaba yokufunxa. Xa iqhagamshelwe ngokupheleleyo, i-CO2₂ kwigesi _yi ifunxwa kwisigaba solwelo, kwaye izinto ezingafunxwanga zikhutshwa phezulu kwinqaba yokufunxwa zingene kwi-decarburised gas cooler kunye ne-separator. Igesi ephuma kwi-decarburised gas separator ingena kwi-feed gas mercury removal unit, kwaye i-condensate iya kwi-flash tank.

i-CO₂ Umxholo kwi-natural treatment ungaphantsi kwe-50ppmv.

I-MEDA ithathe i-CO2₂ ibizwa ngokuba lulwelo olutyebileyo, kwaye ithunyelwa kwi-flash tower, kwaye igesi yendalo ekhutshwe phantsi koxinzelelo oluncitshisiweyo ithunyelwa kwinkqubo yamafutha. Emva kokutsha, ulwelo olutyebileyo lutshintsha ubushushu nesisombululo (ulwelo oluthambileyo) oluphuma ezantsi kwi-regeneration tower, kwaye emva koko ubushushu bunyuswa bube yi-~98 °C ukuya kwinxalenye ephezulu yenqaba yokuvuselela.

Ulwelo oluthambileyo oluvela kwinqaba yokuvuselela ludlula kwi-lean-rich liquid heat exchanger kunye ne-lean liquid cooler, ulwelo oluthambileyo luyapholiswa ukuya kuthi ga kwi-~40 ℃, kwaye emva kokuba lucinezelwe yipompo yolwelo oluthambileyo, lungena luvela kwinxalenye ephezulu yenqaba yokufunxa.

Igesi ekwindawo ephezulu yokuphuma kwenqaba yokuvuselela idlula kwi-acid gas cooler ize ingene kwi-acid gas separator. Igesi evela kwi-acid gas separator ithunyelwa kwinkqubo yokukhupha i-acid gas, kwaye i-condensate icinezelwa yipompo yokubuyisela emva koko ithunyelwe kwi-flash separator.

Umthombo wobushushu we-regeneration tower reboiler ufudunyezwa ngeoyile yokudlulisa ubushushu.

Izixhobo eziphambili zenkqubo zale yunithi yinqaba yokufunxa kunye nenqaba yokuvuselela.
