Le phrojekthi iyiyunithi yokubuyisa igesi yomsila we-styrene ehlinzekwa yi-AIR LIQUIDE (Shanghai Industrial Gas Co., Ltd.). Isebenzisa ubuchwepheshe bokushuba kwengcindezi efakwe kwi-Skid ukuze ibuyise i-hydrogen kusuka kugesi yomsila yokukhiqiza i-styrene. Umthamo wokucubungula oklanyelwe wale yunithi ungama-2,500 Nm³/h, ophatha igesi yomsila kusuka esitshalweni se-styrene. Izingxenye eziyinhloko zale gesi yi-hydrogen, i-benzene, i-toluene, i-ethylbenzene, nezinye izinto eziphilayo. Uhlelo lusebenzisa inqubo ehlanganisiwe ye-"pre-treatment + PSA". Iyunithi yokwelapha ngaphambi kokwelashwa ifaka izinyathelo ezifana nokujiya kanye nokumunca, isusa ngempumelelo izinto ezihlanganisiwe ze-benzene kusuka kugesi yomsila futhi ivikele i-PSA adsorbent. Iyunithi ye-PSA isebenzisa ukucushwa kwemibhoshongo eyisithupha, lapho ubumsulwa be-hydrogen bomkhiqizo bufinyelela ku-99.5%, kanye nezinga lokubuyisa i-hydrogen lidlula u-80%. Umthamo wokubuyisa i-hydrogen nsuku zonke ungama-60,000 Nm³. Le yunithi yakhelwe ngendlela yokucushwa okufakwe ezinsikeni, lapho lonke uhlelo lwenziwe futhi lwahlolwa efektri, futhi idinga kuphela ukuxhuma amapayipi okungena nawokuphuma kanye nezinsizakalo zesevisi endaweni. Isikhathi sokufakwa singamaviki ama-2 kuphela. Ukusetshenziswa ngempumelelo kwale yunithi efakwe ezinsikeni kunikeza ikhambi eliguquguqukayo nelisebenzayo lokusetshenziswa kwemithombo yegesi yangemuva emabhizinisini e-petrochemical, ikakhulukazi afaneleka ezimweni ezinomhlaba olinganiselwe noma ezidinga ukuthunyelwa okusheshayo.
