Kutsekemera kwa Gasi Kumaphatikiza Kuchotsa Sulphurization ya Molecular Sieve ndi Kutaya Madzi M'thupi kwa Zomera za LNG za M'badwo Wotsatira
Pamene makampani apadziko lonse lapansi opanga gasi wachilengedwe wosungunuka (LNG) akupitilizabe kuyeretsa bwino mu 2026, chotsukira mpweya Yasanduka malo ogwirira ntchito yokonzekera chithandizo, kuphatikiza njira yapamwamba yochotsera sulphurization ya Molecular sieve ndi chipangizo chochotsera madzi m'thupi cha TEG gas kuti ipereke mpweya wouma kwambiri, wopanda sulfure wothira madzi m'madzi.
Mwachikhalidwe, machitidwe okhala ndi amine ankagwira ntchito yochotsa mpweya wa asidi wambiri, koma njira yamakono yochepetsera shuga tsopano ikuphatikizapoKuchotsa sulfurization ya sieve ya maselo layer—pogwiritsa ntchito ma zeolite opangidwa okhala ndi kukula koyenera kwa ma pore—kuti apukutire mpweya mwa kusakaniza ma residual mercaptans, COS, ndi kutsitsa H₂S mpaka milingo ya sub-ppm. Kuchotsa sulfure mozama kumeneku ndikofunikira kwambiri pa zosinthira kutentha za LNG plant cryogenic, komwe ngakhale mankhwala ang'onoang'ono a sulfure angayambitse mapangidwe olimba ndi kuipitsa pa -162 °C.
Kuphatikiza pa sieve iyi ya molecular pali chipangizo choyeretsera mpweya cha TEG, chomwe chimagwiritsa ntchito triethylene glycol kuyamwa nthunzi ya madzi, zomwe zimapangitsa kuti madzi achepetse kutentha kwa 40–60 °C ndikuchepetsa madzi kufika pa 0.1 lb/MMscf. Zikakonzedwa motsatizana pa sieve imodzi yokometsera mpweya, kusakaniza kwa Molecular sieve ndi TEG dehydration sequence kumatsimikizira kuti mpweya wokonzedwayo ukukwaniritsa zofunikira zonse za mapaipi ndi zolowera za LNG plant popanda kufunikira ziwiya zosiyana, zogwiritsa ntchito malo.
Zambiri zaposachedwa kuchokera ku fakitale yayikulu ya LNG ku Southeast Asia zikuwonetsa kuti kusintha mayunitsi odziyimira pawokha ndi njira yolumikizirana yochepetsera kutsekemera kwa gasi kunachepetsa mphamvu yobwezeretsanso ndi 35% ndikuchepetsa kugwiritsa ntchito mphamvu yobwezeretsanso ndi pafupifupi 20%. Ogwiritsa ntchito amapindulanso ndi zida zogawana, ma valve osinthira okha, ndi kuzungulira kwa gasi wobwezeretsanso komwe kumathandizira kuti kutentha kugwire bwino ntchito.
"Popeza malire okhwima a mpweya woipa akuyamba kugwira ntchito chaka chino, kutsika kwa mpweya wotsekemera sikulinso chinthu chongowonjezera—ndipo ndi maziko a ntchito zodalirika za fakitale ya LNG," anatero injiniya wamkulu wa makina ku kampani yotchuka ya EPC. "Kuchotsa sulphurization ya molecular sieve kumapereka kunyezimira komaliza, pomwe Chipinda choyeretsera mpweya cha TEG zimatsimikizira kuti sizingaume mufiriji; pamodzi, amapanga njira yolimba yokonzekera chithandizo chomwe chimawonjezera nthawi yogwira ntchito yothira madzi.
Pamene mphamvu ya LNG padziko lonse lapansi ikuwonjezeka ndi matani opitilira 60 miliyoni pachaka mu 2026-2027, kufunikira kwa ma skid otsekemera a gasi ang'onoang'ono komanso ogwira ntchito bwino okhala ndi sieve yophatikizika ya molecular ndi glycol dehydration kukuyembekezeka kuwonjezeka, zomwe zikuyambitsa luso la kapangidwe ka modular kokhazikika pa skid komanso kuthekera kowunikira patali.
