Piv nrog rau cov tsoos activated alumina, Chemxinactivated alumina siv(AA) muaj thaj chaw saum npoo ntau dua 20% siab dua, cov dej zoo li qub adsorption ntau dua lossis sib npaug li 20%, thiab qhov chaw kuaj dej dynamic dej adsorption ntau dua lossis sib npaug li 18%. Nyob rau tib lub sijhawm, qhov nruab nrab regeneration cua sov ntawm desorption ntawm AA yog qhov me me thaum adsorbing tib cov dej. Nws tuaj yeem rov tsim dua tshiab siv tsuas yog compression khib nyiab thaum tshav kub kub. Lub peev xwm adsorption yog loj dua nyob rau hauv tib lub voj voog, thiab lub voj voog lub neej ntev dua.
Nws tau raug txheeb xyuas nyob rau hauv ntau tus neeg siv tiag tiag uas Chemxin siab adsorption activated alumina yog tsim rau ntau lub zog-txuag pov tseg thaum tshav kub kub rov qab xoom roj siv tshuab ziab khaub ncaws thiab moj tej tawg tshav kub regeneration xoom gas noj tshuab ziab khaub ncaws, thiab tuaj yeem ruaj khov tau cov roj tiav nrog qis dua. dew point.
Rau lub siab dew point yuav tsum tau hauv qab no -40 degree, nws raug nquahu kom sau Chemxin AA, los yog ua kom tiav cov filling.
Piv txwv li, AA +zeolite molecular sieve, los yog AA + zeolite molecular sieve +silica gelthiab lwm yam khoom, tuaj yeem tau txais cov roj tiav nrog lub siab dew point ntawm -40 degree rau -80 degree .
