Natural Gasi Kuyeretsa System Molecular sieve desulphurization

Ndi chitukuko cha anthu athu, timalimbikitsa mphamvu zoyera, choncho kufunikira kwa gasi wachilengedwe monga mphamvu yoyera kukuwonjezekanso. Komabe, pogwiritsira ntchito gasi wachilengedwe, zitsime zambiri za gasi nthawi zambiri zimakhala ndi hydrogen sulfide, yomwe imayambitsa dzimbiri ndi mapaipi, kuipitsa chilengedwe ndikuyika thanzi la anthu pachiwopsezo. Ndi chitukuko cha sayansi ndi luso, Kugwiritsa ntchito kwambiri gasi desulfurization luso lathetsa mavutowa, koma pa nthawi yomweyo, mtengo wa kuyeretsa gasi ndi chithandizo chawonjezeka moyenerera.

Molecular sieve desulphurization (yomwe imatchedwanso desulfurization) skid, yomwe imatchedwanso molecular sieve sweeting skid, ndi chipangizo chofunikira kwambiri pakuyeretsa gasi kapena pulojekiti yowongolera gasi.

Sieve ya maselo ndi alkali zitsulo aluminosilicate kristalo yokhala ndi chigoba komanso mawonekedwe a microporous yunifolomu. Ndi adsorbent yokhala ndi magwiridwe antchito abwino kwambiri, kutsatsa kwakukulu komanso kusankha kwa adsorption. Choyamba, pali njira zambiri zokhala ndi kukula kwa pore ndi mabowo okonzedwa bwino mu dongosolo la sieve ya maselo, zomwe sizimangopereka malo aakulu kwambiri, komanso zimalepheretsa kulowa kwa mamolekyu akuluakulu kuposa mabowo; Kachiwiri, pamwamba pa sieve ya maselo imakhala ndi polarity yayikulu chifukwa cha mawonekedwe a ma ionic lattice, chifukwa chake imakhala ndi mphamvu zambiri zotsatsa mamolekyu opanda unsaturated, mamolekyu a polar ndi mamolekyu owuluka. Madzi ndi hydrogen sulfide ndi mamolekyu a polar, ndipo kukula kwake kwa molekyulu ndi kocheperako poyerekeza ndi m'mimba mwake wa sieve ya maselo. Pamene mpweya waiwisi womwe uli ndi madzi amadutsa pa bedi la sieve kutentha kwa firiji, kufufuza madzi ndi hydrogen sulfide zimatengedwa, motero, zomwe zili m'madzi ndi hydrogen sulfide mu mpweya wa chakudya zimachepetsedwa, ndipo cholinga cha kutaya madzi m'thupi ndi desulfurization chimakwaniritsidwa. The adsorption process of molecular sieve ikuphatikizapo capillary condensation ndi thupi adsorption chifukwa van der Waals force .Malinga ndi Kelvin equation, capillary condensation amachepetsa ndi kuwonjezeka kutentha, pamene thupi adsorption ndi njira exothermic, ndipo kutsekemera kwake kumachepa ndi kuwonjezeka kwa kutentha. ndi kuchuluka kwa kuthamanga kwa magazi; Choncho, ndondomeko ya adsorption ya sieve ya maselo nthawi zambiri imachitika pa kutentha kochepa komanso kuthamanga kwambiri, pamene kusinthika kwachangu kumachitika pa kutentha kwakukulu ndi kuchepetsa kupanikizika. Pansi pa kutentha kwapamwamba, mpweya woyeretsa komanso wochepetsetsa wotsitsimutsa, molecular sieve adsorbent imatulutsa adsorbate mu micropore mu mpweya wotsitsimutsa mpaka kuchuluka kwa adsorbent mu adsorbent kufika pamlingo wotsika kwambiri. Imakhalanso ndi mwayi wotsatsa madzi ndi hydrogen sulfide kuchokera ku mpweya wa chakudya, pozindikira kusinthika ndi kubwezeretsanso kwa sieve.

Zida zazikulu zikufotokozedwa motere.

Zindikirani: 1. Mndandanda wa zida zazikulu zogwirira ntchito zikugwirizana ndi dongosolo la PID

2. Mndandanda wa zida zopangira ntchito ndi zaka 2 zidzaperekedwa mu chikalata china.

3. Muyeso wa mawonekedwe akunja a chipangizocho ndi matako a gost, ndipo ma gaskets ndi zomangira zimaperekedwa pamalire a tanki yosungiramo ndi zida;

4.Deta yaukadaulo ya zida zomwe zafotokozedwa mu Annex iyi zidzakhazikitsidwa ndi mapangidwe omaliza.
