Pulojekitiyi ndi gawo lobwezeretsa mpweya wa m'mbuyo la fakitale yopanga isobutylene ya Shenyang Paraffin Chemical Co., Ltd. Imagwiritsa ntchito ukadaulo wothira mpweya wa pressure swing kuti ibwezeretse haidrojeni kuchokera ku mpweya wa m'mbuyo wa kupanga isobutylene. Mphamvu yokonza chipangizochi ndi3,600 Nm³/h.

Zigawo zazikulu za mpweya wosaphika ndihaidrojeni, methane, mahydrocarboni a C3-C4, ndi zina zotero., yokhala ndi hydrogen pafupifupi 35-45%. Dongosolo la PSA limagwiritsa ntchito mawonekedwe a nsanja zisanu ndi zitatu ndipo lili ndi chipangizo choyeretsera chomwe chingagwiritsidwe ntchito pochotsa ma hydrocarbon olemera ndi zinyalala kuchokera ku mpweya wosaphika, kuteteza moyo wa adsorbents.

Kuyera kwa chinthu cha haidrojeni kumatha kufika99.5%ndipo kuchuluka kwa haidrojeni komwe kumatuluka kumaposa85%. Kuchuluka kwa haidrojeni komwe kumabwezedwa tsiku lililonse ndi 86,000 Nm³. Kupanikizika kwa kapangidwe ka chipangizocho ndi 1.8 MPa, ndipo makina owongolera okha amagwiritsidwa ntchito kuti agwire ntchito popanda woyendetsa. Nthawi yokhazikitsa pamalopo ndi miyezi inayi.

Poganizira za malo otentha kwambiri m'nyengo yozizira yakumpoto, makinawa ali ndi njira zonse zotetezera kuzizira komanso zotetezera kutentha. Chipangizochi chikayamba kugwira ntchito, chimagwiritsa ntchito hydrogen yotsala panthawi yopanga isobutylene, ndipo hydrogen imawonjezeka pachaka.30 miliyoni Nm³, kupeza phindu lalikulu pazachuma.
