Kusonkhanitsa ndi kunyamula gasi wa m'munda wamafuta

Kusonkhanitsa ndi kukonza njira zoyendera mafuta (monga mafuta osakonzedwa) nthawi zambiri kumaphatikizapo: kusonkhanitsa mafuta, kukonza gasi; Kutumiza mpweya wouma ndi hydrocarbon yopepuka; Kutumiza mafuta osakonzedwa motsekedwa, kukhazikika kwa mafuta osakonzedwa, kusungidwa kwa hydrocarbon yopepuka, ndi zina zotero.

Kusonkhanitsa gasi wamafuta

Mafuta osaphika akatuluka m'chitsime cha mafuta ndipo akayesedwa ndi choyezera, mafuta ndi gasi zimanyamulidwa kupita ku choyezera mafuta ndi gasi cha siteshoni yotumizira mafuta. Gasi wa Oilfield amalekanitsidwa ndi mafuta osaphika ndipo amalowa mu netiweki yosonkhanitsa gasi. Nthawi zambiri, siteshoni yosonkhanitsa gasi yodzikakamiza kapena yowonjezera imamangidwa mu siteshoni yophatikizana ya fakitale yopanga mafuta. Ma compressor olimbikitsira mafuta nthawi zambiri amakhala ma compressor ambiri obwerezabwereza. Kuthamanga kwa kulowa kumatha kuyandama, ndipo kuthamanga kwa kutuluka kumadalira kuthamanga kwa dongosolo. Kuthamanga kwakukulu kwa kutuluka ndi 0.4MPa.

Kusonkhanitsa ndi kunyamula mafuta osakonzedwa bwino

Kusonkhanitsa ndi kunyamula mafuta osakonzedwa bwino ndiye chinthu chofunikira kwambiri chochotsera mafuta osakonzedwa bwino kuchokera ku mafuta osakonzedwa pogwiritsa ntchito njira yokhazikika ya mafuta osakonzedwa, ndipo ndi chimodzi mwa zinthu zofunika kwambiri kuti mafuta osakonzedwa asamatayike.

Pa siteshoni yosamutsira mafuta, mafuta osaphika omwe amadutsa mu cholekanitsa mafuta ndi gasi amalowa mu chotsukira madzi chopanda mafuta, kenako amatumizidwa ku siteshoni yochotsera madzi osaphika kudzera mu thanki yosungira madzi ndi ng'anjo yotenthetsera yotumizira kunja. Apa, mafuta osaphika amadutsa mu chotsukira madzi chopanda mafuta, kenako amalowa mu ng'anjo yotenthetsera madzi kuti atenthe, kenako amalowa mu chotsukira madzi chophatikizana. Mafuta osaphika akatha, mafuta osaphika amalowa mu thanki yosungiramo mafuta (madzi a mafuta osaphika ndi ochepera 0.5%), kenako amapopedwa mu unit yokhazikitsa mafuta osaphika, ndipo mafuta osaphika akatha, amalowa mu thanki yosungiramo mafuta kuti atumize kunja.

Mu njira yotsekedwa ya malo otumizira mafuta ndi malo ochotsera madzi m'thupi, madzi aulere amatulutsidwa pasadakhale ndikusakanizidwa ndi madzi olowetsedwa m'malo operekera mafuta kuti achepetse kugwiritsa ntchito mphamvu zopangira.

Kukonza gasi wa m'munda wamafuta

Mpweya wochokera ku siteshoni yodzipangira mphamvu umalowa mu unit yozizira pang'ono (kapena cryogenic), komwe umapanikizika, kuzizira ndikulekanitsidwa pamodzi ndi mpweya wosazizira kuchokera ku unit yokhazikika ya mafuta osakonzedwa kuti ubwezeretse zinthu zomwe zili pamwamba pa C3 (kapena C2), ndipo mpweya wouma umatumizidwa kunja.

Njira yosonkhanitsira ndi mayendedwe a hydrocarbon yopepuka

Kusonkhanitsa ndi mayendedwe a hydrocarbon pang'ono kumagwiritsa ntchito njira yoyendera mapaipi, ndipo dongosololi limapangidwa ndi malo osungira othandizira, malo otumizira, malo osungira ambiri, malo oyezera katundu kunja ndi netiweki yofananira ya mapaipi.

The chipangizo chobwezeretsa ma hydrocarbon ochepa Ili ndi thanki yosungiramo zinthu, yomwe imagwiritsidwa ntchito pokonza madzi m'thupi, kulumikiza zinthu, chotetezera pampu yotumizira kunja ndi mapaipi otumizira kunja kuti zitsimikizire kuti pakuchitika zinthu mwachizolowezi kapena kutseka chipangizocho pakagwa ngozi. Mphamvu yosungiramo zinthu ya thanki yosungiramo zinthu nthawi zambiri imakhala masiku 1 mpaka 2 a kupanga ma hydrocarbon ochepa.

Ntchito yaikulu ya malo osungiramo mafuta opepuka a hydrocarbon ndikugwiritsa ntchito malo osungiramo mafuta kuti agwirizane ndi kusalingana pakati pa kupanga mafuta opepuka a hydrocarbon ndi kutumiza kunja kwa dzikolo tsiku limodzi, komanso kusunga ndikuyeretsa madzi otuluka m'mapaipi ngati pachitika ngozi ya mapaipi.

Ntchito yaikulu ya malo osungiramo ma hydrocarbon opepuka ndikugwiritsa ntchito thanki yosungiramo zinthu kuti igwirizane ndi kusalingana pakati pa kupanga ndi kutumiza ma hydrocarbon opepuka, kuphatikizapo kusinthasintha kwa zotulutsa za chipangizo chopangira, kusinthasintha kwa zotulutsa zomwe zimachitika chifukwa cha nthawi zosiyanasiyana zosamalira chipangizocho, kukonza chomera cha ethylene popanda kukonza ammonia, ndipo gawo la mafuta liyenera kupitiliza kupereka kusungirako kwa ma hydrocarbon opepuka omwe atengedwa kuchokera ku mpweya wodyetsa.

Malo osungiramo ma hydrocarbon ochepa komanso malo oyezera zinthu zotumizira kunja ndi malo akuluakulu otulutsira zinthu zopangira ma hydrocarbon amadzimadzi zomwe zimaperekedwa ndi malo opangira mafuta a ethylene, malo osonkhanitsira ma hydrocarbon opepuka opangidwa ndi mayunitsi osiyanasiyana obwezeretsa ma hydrocarbon amagetsi, komanso malo osungira ndi mayendedwe a ma hydrocarbon amagetsi.

Kutumiza ndi kubweza mpweya wouma

Mpweya wouma umakonzedwa ndi kukonzedwanso ukatha kubwezeretsedwa. Mpweya wouma wambiri ukatha kubwezeretsedwanso umatumizidwa ku Dahua ndi mafakitale a methanol ngati zinthu zopangira mankhwala, ndipo gawo lina la mpweya wouma limatumizidwanso ku siteshoni yosamutsira mafuta pamunda wamafuta ngati mafuta otenthetsera uvuni ndi boiler. Kubwerera kwa mpweya wouma ndi njira yosiyana yosonkhanitsira mpweya. Nthawi yomweyo, mpweya wouma wina umalowetsedwa m'malo osungira mpweya nthawi yachilimwe. Umapangidwa m'nyengo yozizira kuti achepetse kusowa kwa mpweya wachilengedwe komanso kufunikira kwake.

Mpweya wina wouma umagwiritsidwa ntchito popanga magetsi ndi gasi kwa anthu okhala m'deralo.
