Njira yobwezeretsanso ma hydrocarbons opepuka kuchokera ku gasi wogwirizana nawo m'minda yamafuta (1)

Thekubwezeretsedwa kwa ma hydrocarbons owala kuchokera ku gasi wogwirizana nawo m'minda yamafuta ndi njira yofunika kwambiri pamakampani amafuta ndi gasi. Mpweya wophatikizana, womwe nthawi zambiri umapezeka pafupi ndi mafuta osaphika, uli ndi zinthu zofunika kwambiri monga zamadzimadzi achilengedwe (NGL) ndi gasi wamafuta amafuta (LPG). Kupezanso ma hydrocarbon owalawa kumangowonjezera mtengo wa gasi komanso kumathandizira kuchepetsa kutulutsa mpweya wowonjezera kutentha. M'nkhaniyi, tiwona kufunikira kwa NGL ndi LPG kuchira ku gasi wogwirizana ndi matekinoloje omwe akukhudzidwa ndi njirayi.

Kuchira kwa NGL kuchokera ku gasi wogwirizana kumakhudza kulekanitsa ndi kuchotsa zinthu za gasi zachilengedwe monga ethane, propane, ndi butane. Zidazi zimakhala ndi phindu lalikulu pazamalonda ndipo zimagwiritsidwa ntchito ngati chakudya chamafuta amafuta, komanso kupanga mapulasitiki, mphira wopangira, ndi zinthu zina zamafakitale. Kuchira kwaNGL kuchokera ku gasi wogwirizana nawondikofunikira kuti pakhale mwayi wopeza chuma cha gasi ndikuchepetsa kuwononga zinthu zamtengo wapatali.

Kufotokozera mwachidule za ndondomekoyi ndi:

1) Kusakaniza kwa gasi ndi njira yolimbikitsira

1) Kufotokozera ndondomeko

Mpweya wodyetserako umakanikizidwa ku 0.3 MPaG ndiyeno umasakanizidwa ndi Low Pressure stream ndiyeno kukakamizidwa ku 3.9 MPaG. Mtsinje wosakanikirana umasakanizidwa ndi High Pressure ndikulowa mu chipangizo chapansi.

2) Mapangidwe a magawo

Mphamvu yopangira gasi:

Kuthamanga Kwambiri: 12500 Nm³/h;

Kuthamanga Kwambiri: 16166.7 Nm³/h;

2) Njira yowonongeka kwa gasi

1) Kufotokozera ndondomeko

Kukhalapo kwa chinyezi mu gasi wachilengedwe nthawi zambiri kumabweretsa zowopsa: chinyezi ndi gasi zimatha kupanga ma hydrates kapena ayezi kuti atseke mapaipi pansi pamikhalidwe ina.

Kutaya madzi m'thupi kwa gasi kumatengera njira yoyezera sieve adsorption. Popeza sieve ya molekyulu imakhala ndi kusankhidwa kwamphamvu kwa adsorption komanso mawonekedwe apamwamba adsorption pansi pa mpweya wochepa wa madzi pang'onopang'ono, chipangizochi chimagwiritsa ntchito 4A molecular sieve monga dehydration adsorbent.

Chigawochi chimagwiritsa ntchito njira ya nsanja ziwiri kuti itenge chinyezi, imagwiritsa ntchito njira ya TSA kuti ifufuze chinyezi chomwe chili mu sieve ya maselo, ndipo imagwiritsa ntchito njira ya condensation kuti isungunuke ndikulekanitsa chinyezi chosungunuka kuchokera ku adsorbent.

2) Mapangidwe a magawo

Kudyetsa gasi processing mphamvu 70 × 10⁴Nm³/d

Kuthamanga kwa Adsorption 3.5MPaG

Adsorption kutentha 35 ℃

Kusintha kwamphamvu 3.5MPaG

Kusintha kutentha ~ 260 ℃

Regenerative kutentha gwero matenthedwe mafuta

Zomwe zili mu H₂O mu gasi woyeretsedwa ＜ 5 ppm
