Njira yobwezeretsera ma hydrocarbon opepuka kuchokera ku mpweya wogwirizana nawo m'minda yamafuta (1)
The kubwezeretsa ma hydrocarbons opepuka Kuchotsa mpweya wokhudzana ndi mafuta m'magawo amafuta ndi njira yofunika kwambiri mumakampani opanga mafuta ndi gasi. Gasi wogwirizana, womwe nthawi zambiri umapezeka pamodzi ndi mafuta osakonzedwa, uli ndi zinthu zofunika monga madzi achilengedwe a gasi (NGL) ndi gasi wamafuta osungunuka (LPG). Kubwezeretsa ma hydrocarbon opepuka awa sikuti kumangowonjezera phindu la mpweya komanso kumathandiza kuchepetsa mpweya woipa. M'nkhaniyi, tifufuza kufunika kwa kubwezeretsa NGL ndi LPG kuchokera ku gasi wogwirizana ndi mafuta komanso ukadaulo womwe umagwiritsidwa ntchito pankhaniyi.
Kubwezeretsa kwa NGL kuchokera ku mpweya wogwirizana nawo Zimaphatikizapo kulekanitsa ndi kutulutsa zakumwa za gasi wachilengedwe monga ethane, propane, ndi butane. Zigawozi zili ndi phindu lalikulu pamalonda ndipo zimagwiritsidwa ntchito ngati chakudya cha zomera za petrochemical, komanso popanga mapulasitiki, rabala yopangidwa, ndi zinthu zina zamafakitale. NGL kuchokera ku gasi wogwirizana ndikofunikira kwambiri pakukweza mphamvu ya mpweya komanso kuchepetsa kuwononga zinthu zofunika kwambiri.
Kufotokozera mwachidule za ndondomekoyi ndi:
1) Njira yosakaniza ndi kulimbitsa mpweya wachilengedwe
1) Kufotokozera njira
Mpweya wothira umapanikizika kufika pa 0.3 MPaG kenako umasakanikirana ndi mtsinje wa Low Pressure kenako umapanikizika kufika pa 3.9 MPaG. Kenako mtsinje wosakanikirana umasakanikirana ndi High Pressure ndikulowa mu chipangizo chotsikira.
2) Magawo a kapangidwe
Mphamvu yogwiritsira ntchito mpweya wothira chakudya:
Kupanikizika Kwambiri: 12500 Nm3/h;
Kupanikizika Kochepa: 16166.7 Nm3/h;
2) Dongosolo la madzi m'thupi la mpweya wachilengedwe
1) Kufotokozera njira
Kupezeka kwa chinyezi mu mpweya wachilengedwe nthawi zambiri kumabweretsa zotsatirapo zoopsa: chinyezi ndi mpweya wachilengedwe zimatha kupanga madzi kapena ayezi kuti atseke mapaipi pansi pa mikhalidwe ina.
Kutaya madzi m'thupi pogwiritsa ntchito mpweya wachilengedwe kumagwiritsa ntchito njira yopezera madzi m'thupi pogwiritsa ntchito sieve ya molecular. Popeza sieve ya molecular ili ndi njira yosankha madzi m'thupi komanso mphamvu zambiri zopezera madzi m'thupi pogwiritsa ntchito nthunzi yochepa ya madzi, chipangizochi chimagwiritsa ntchito sieve ya 4A molecular ngati njira yopezera madzi m'thupi.
Chipangizochi chimagwiritsa ntchito njira ya nsanja ziwiri kuti chitenge chinyezi, chimagwiritsa ntchito njira ya TSA kuti chisanthule chinyezi chomwe chimatengedwa mu sieve ya mamolekyu, ndipo chimagwiritsa ntchito njira ya condensation kuti chichepetse ndikulekanitsa chinyezi chomwe chimachotsedwa ku adsorbent.
2) Magawo a kapangidwe
Mphamvu yogwiritsira ntchito mpweya wothira chakudya 70 × 104 Nm3/d
Kuthamanga kwa madzi 3.5MPaG
Kutentha kwa madzi 35 ℃
Kuthamanga kwa kukonzanso 3.5MPaG
Kutentha kwa kusinthika ~260 ℃
Mafuta odzola odzola omwe amachokera ku kutentha kosinthika
Zomwe zili mu H2O mu mpweya woyeretsedwa ＜ 5 ppm
