Le phrojekthi iyiyunithi yokubuyisa igesi yomsila yesitshalo sokukhiqiza i-isobutylene seShenyang Paraffin Chemical Co., Ltd. Isebenzisa ubuchwepheshe bokufaka i-pressure swing ukuze ibuyise i-hydrogen kugesi yomsila yokukhiqizwa kwe-isobutylene. Amandla okucubungula aklanyelwe ale divayisi yi-3,600 Nm³/h.

Izingxenye eziyinhloko zegesi eluhlaza yilezii-hydrogen, i-methane, ama-hydrocarbon e-C3-C4, njll., okuqukethwe yi-hydrogen cishe ku-35-45%. Uhlelo lwe-PSA lusebenzisa ukucushwa kwemibhoshongo eyisishiyagalombili futhi luhlonyiswe ngeyunithi yokwelapha ezinikele yokususa ama-hydrocarbon asindayo kanye nokungcola okuvela kugesi eluhlaza, okuvikela isikhathi sokuphila sama-adsorbents.

Ubumsulwa bomkhiqizo i-hydrogen bungafinyelela99.5%, futhi izinga lokutakula i-hydrogen lidlula85%. Umthamo we-hydrogen otholakele nsuku zonke ungu-86,000 Nm³. Ingcindezi yomklamo wedivayisi ingu-1.8 MPa, futhi kusetshenziswa uhlelo lokulawula oluzenzakalelayo ukuze kufezwe ukusebenza okungenamuntu. Isikhathi sokufakwa endaweni siyizinyanga ezi-4.

Uma sibheka indawo ephansi yokushisa ebusika basenyakatho, uhlelo luhlonyiswe ngezinyathelo eziphelele zokulwa nokubanda kanye nokushisa. Ngemva kokuba idivayisi isiqalile ukusebenza, iqaphela ukusetshenziswa kwemithombo ye-hydrogen ephumayo ngesikhathi sokukhiqizwa kwe-isobutylene, ngomthamo we-hydrogen otholakele waminyaka yonke ongaphezu kwesilinganiso.Izigidi ezingu-30 ze-Nm³, ukufeza izinzuzo ezinkulu zomnotho.
