Nkhani Zamakampani

Kukonza gasi wachilengedwe ndi njira yochotsera mpweya wamadzi, hydrogen sulfide, mercaptan, ndi mpweya woipa kuchokera ku gasi wachilengedwe. Zida zazikulu zikuphatikizapodehydration unit,gawo la desulfurization,gawo la decarbonization,ndi kuwala kwa hydrocarbon kuchiraunit.

Kuphatikiza pa mayamwidwe ndi ma adsorption,Membrane dehydration unit akuyamba kutchuka m'mafakitale ochotsa madzi m'thupi mwa gasi. Izi zimaphatikizapo kugwiritsa ntchito nembanemba zotha kutha pang'ono kuti muchotse mpweya wamadzi mumtsinje wa gasi. Ma nembanembawa amalola kuti mamolekyu amadzi adutse pamene akusunga mpweya wouma. Kutaya madzi m'thupi kwa Membrane kumadziwika chifukwa cha kuphweka kwake, kaphazi kakang'ono, komanso kugwiritsa ntchito mphamvu zochepa. Ndikoyenera makamaka pazigawo zing'onozing'ono zopangira gasi ndi ntchito zomwe malo ndi mphamvu zowonjezera ndizofunikira. Komabe, kutaya madzi m'thupi kwa membrane sikungakhale kothandiza pakukwaniritsa kuchuluka kwamadzi otsika kwambiri poyerekeza ndi mayamwidwe ndi njira zotsatsa.

Zomera zowononga mpweya wachilengedwe, amadziwikanso kutimayunitsi oyanika gasi kapena kuyanika zomera, ndi zipangizo zofunika mu gasi gasi. Iwo ali ndi udindo wochotsa mpweya wamadzi mu gasi kuti ateteze dzimbiri, mapangidwe a hydrate, ndi zina zomwe zingabwere panthawi yoyendetsa ndi kukonza. Pali njira zingapo zochepetsera madzi m'thupi zomwe zimagwiritsidwa ntchito muzomerazi, chilichonse chili ndi zabwino zake komanso zolephera zake. Kumvetsetsa kusiyana pakati pa njirazi n'kofunika kwambiri posankha njira yoyenera kwambiri yogwiritsira ntchito.

BOG yotsika kutentha imayamba kulowa m'bokosi lozizira kuti itenthedwenso kutentha kwa chipinda ndikulowa mu BOG compressor chifukwa cha kupanikizika. BOG yopanikizidwa imalowa m'bokosi lozizira la liquefaction, itakhazikika, imasungunuka, ndikutenthedwa bwino mu mbale-fin heat exchanger, ndikubwerera ku tanki yosungiramo LNG ngati chinthu cha LNG pambuyo powombera.Mtengo wa LNG.

Thegasi decarbonization chomera akukonzekera kuti aziyendetsedwa ndi magetsi a mains. Magetsi a chipangizo choyeretsera gasi amagwiritsidwa ntchito makamaka pamapampu ozungulira a MDEA, zida ndi machitidwe owongolera, etc. Mafuta amafuta amagwiritsidwa ntchito makamaka pang'anjo zamafuta otentha.

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.

TheLNG process technology yakhala ikupita patsogolo kwambiri pamakampani opanga gasi, zomwe zachitika posachedwa zikuwonetsa kupita patsogolo kwaukadaulo wamafakitale a LNG. Pomwe kufunikira kwa gasi kukukulirakulira padziko lonse lapansi, kuyang'ana paukadaulo wowongolera wa LNG wakhala wofunikira kwambiri. Chimodzi mwazotsogola zaposachedwa kwambiri muukadaulo wa LNG ndikutukuka kwa njira zotsogola zamadzimadzi zomwe zimapangitsa kuti zomera za LNG zizigwira ntchito bwino komanso zachilengedwe.
