High Quality China TEG Dehydration Unit Factories - PSA decarbonization skid pakuyeretsa gasi - Rongteng

Kufotokozera

Kutsetsereka kwa gasi wachilengedwe (decarbonization) skid, ndi chida chofunikira pakuyeretsa kapena kuchiza gasi.

Zomwe zili mu mpweya woipa mu mpweya wabwino wa gasi siziyenera kupitirira 3%. Ndipo mpweya woipa m'madzi utatha chitsulocho chimakhala ndi zowonongeka kwambiri. Ngati mtengo wa PH uli wofanana, chiŵerengero cha acidity cha carbon dioxide chimakhalanso chapamwamba, kotero kuti mpweya woipa wa carbon dioxide pazitsulo umakhalanso wapamwamba.

Pressure swing adsorption (PSA) ndiukadaulo watsopano womwe umagwiritsidwa ntchito kusiyanitsa kusakaniza kwa gasi muukadaulo wolekanitsa wa adsorption. Poyerekeza ndi njira yachikhalidwe yoyamwitsa mankhwala, ukadaulo wa PSA ndiwokongola pachuma pakuchotsa ndi kuchira kwa H2S ndi CO2 ku gasi, ndipo ukupangidwa mwamphamvu.

PSA mpweya kulekana luso ali ndi ubwino wa ntchito yosavuta, otsika kuthamanga kutaya, kutaya madzi m'thupi pamene kuchotsa CO2, otsika mame mpweya woyeretsedwa ndi madzi, ndipo mankhwala akhoza kukwaniritsa zofunika za kunja gasi. PSA angagwiritsidwe ntchito CO2 ndende ndi kusankha desulfurization mu gasi.

Tchati choyenda

Adsorption inachitika pansi pa kupanikizika ndipo desorption inachitika pansi pa kupanikizika kochepa. Chifukwa kuzungulira kwa adsorption ndi kwaufupi ndipo kutentha kwa adsorption sikungatheke pakapita nthawi, kumatha kugwiritsidwa ntchito pochotsa. Choncho, kutentha kwa bedi la adsorption chifukwa cha kutentha kwa adsorption ndi kutentha kwa desorption kumakhala ndi kusintha kochepa, komwe kumatha kuonedwa ngati njira ya isothermal. Single fixed adsorption bedi ntchito, kaya kutentha swing adsorption kapena kuthamanga kugwedezeka adsorption, chifukwa adsorbent ayenera kusinthidwa, ndi adsorption ndi intermittent. M'makampani, mabedi awiri kapena kuposerapo amagwiritsidwa ntchito, kotero kuti kutsatsa ndi kusinthika kwa bedi la adsorption kumachitika mosinthana (kapena mozungulira), kuti zitsimikizire kupitiliza kwa njira yonse yotsatsa.

Zogwira ntchito

Kuchita bwino kwa kuthamanga kwa swing adsorption decarbonization skid ndi 90%.CO2 imatha kulekanitsidwa ndi kusintha kwamphamvu komanso kutengera thupi, popanda kuchitapo kanthu ndi mankhwala. Kuphatikiza pa kuchotsa CO2, teknoloji ya PSA imagwiritsidwa ntchito kwambiri pobwezeretsa ndi kuyeretsa H2, CH4, CO, CO2 ndi mpweya wina.
