High Quality China Natural Gasi Decarbonisation Factory - Molecular sieve kutaya madzi m'thupi skid - Rongteng

Kufotokozera

Molecular sieve dehydration skid ndi chida chofunikira kwambiri pakuyeretsa gasi kapena kukonza gasi. Sieve ya maselo ndi alkali chitsulo aluminosilicate krustalo ndi chimango dongosolo ndi yunifolomu microporous kapangidwe. Pamene mpweya wodyetsa womwe uli ndi madzi otsatizana umadutsa pa bedi la sieve ya maselo kutentha kwa firiji, madzi otsatiridwa ndi mercaptan amatengedwa, motero kuchepetsa madzi ndi mercaptan zomwe zili mu gasi wodyetsa, kuzindikira cholinga cha kutaya madzi m'thupi ndi desulfurization. njira ya adsorption ya sieve ya maselo nthawi zambiri imachitika pa kutentha kochepa komanso kuthamanga kwambiri, pamene kusinthika kwa desorption kumachitika pa kutentha kwakukulu komanso kutsika kochepa. Pansi pa kutentha kwakukulu, mpweya woyeretsa komanso wochepetsetsa wotsitsimutsa, molecular sieve adsorbent imatulutsa adsorbate mu micropore mu mpweya wotsitsimutsa mpaka kuchuluka kwa adsorbate mu adsorbent kufika pamlingo wochepa kwambiri, ndipo amatha kuyamwa madzi ndi mercaptan kuchokera ku gasi wodyetsa, pozindikira kusinthika kwa maselo ndi kubwezeretsanso ndondomeko ya sieve.
Molecular sieve njira ndi njira yakuya madzi m'thupi, amene nthawi zambiri ntchito otsika kutentha condensation ndondomeko kulekana, monga gasi condensate (NGL) kuchira ndi kutaya madzi m'thupi popanga liquefied gasi (LNG). Kuphatikiza apo, kuchepa kwa maselo a sieve kumagwiritsidwanso ntchito popanga gasi woponderezedwa wamafuta apagalimoto.

Kutaya madzi m'thupi kwa molecular sieve kumagwiritsidwa ntchito pazochitika zotsatirazi:
a. Kumene mame a gasi amayenera kukhala osachepera -40 ℃.
b. Ndiwoyenera kuwongolera mame a hydrocarbon powongolera mpweya wowonda kwambiri.
c. Mpweya wachilengedwe umakhala wopanda madzi komanso amayeretsedwa nthawi yomweyo.
d. Pamene gasi wachilengedwe wokhala ndi H2S watsitsidwa ndi kusungunuka mu glycol, zimayambitsa kutulutsa mpweya wosinthika.
e. Pamene LPG ndi NGL kuchepa madzi m'thupi ayenera kuchotsa trace sulfide (H2S, CO, COS, CS2, mercaptan) nthawi yomweyo.

Tchati choyenda

Fixed bedi adsorbers ntchito molecular sieve kuchepa madzi m'thupi, kotero unit ayenera kukhala ndi adsorbers osachepera awiri, mmodzi mu adsorption madzi m'thupi siteji, wina mu kusinthika ndi kuzirala siteji. Pamene mphamvu ya unit ndi yaikulu kwambiri, ndondomeko ya multi Tower ikhoza kukonzedwanso.
