Le projekthi yiyunithi yokubuyisela igesi yomsila we-styrene enikezelwa yi-AIR LIQUIDE (Shanghai Industrial Gas Co., Ltd.). Isebenzisa itekhnoloji yokufakela i-skid pressure swing adsorption ukubuyisela i-hydrogen kwigesi yomsila yokuvelisa i-styrene. Umthamo wokucubungula oyilwe yile yunithi yi-2,500 Nm³/h, ephatha igesi yomsila kwisityalo se-styrene. Izinto eziphambili zale gesi yi-hydrogen, i-benzene, i-toluene, i-ethylbenzene, kunye nezinye izinto eziphilayo. Inkqubo isebenzisa inkqubo edibeneyo "yonyango lwangaphambi konyango + i-PSA". Iyunithi yonyango lwangaphambi konyango ibandakanya amanyathelo anjengokufuma kunye nokufunxa, isusa ngempumelelo izinto ze-benzene kwigesi yomsila kwaye ikhusele i-PSA adsorbent. Iyunithi ye-PSA isebenzisa ulungiselelo lweenqaba ezintandathu, apho ubumsulwa be-hydrogen yemveliso bufikelela kwi-99.5%, kwaye izinga lokubuyisela i-hydrogen lidlula i-80%. Umthamo wokubuyisela i-hydrogen yemihla ngemihla yi-60,000 Nm³. Le yunithi yenzelwe ulwakhiwo olufakwe kwipali, yonke inkqubo yenziwe kwaye ivavanywe kumzi-mveliso, kwaye ifuna kuphela ukudibanisa imibhobho yokungena kunye neyokuphuma kunye neenkonzo zoncedo kwindawo. Ixesha lokufakelwa liziiveki ezi-2 kuphela. Ukusetyenziswa ngempumelelo kwale yunithi ifakwe kwipali kubonelela ngesisombululo esiguquguqukayo nesisebenzayo sokusetyenziswa kwemithombo yegesi yomsila kumashishini e-petrochemical, ngakumbi afanelekileyo kwiimeko ezinomhlaba omncinci okanye ezifuna ukuthunyelwa ngokukhawuleza.
