Le phrojekthi iyiyunithi yokukhiqiza i-hydrogen yesitshalo sokuhlanza i-diesel esingamathani angu-700,000 ngonyaka se-Yumen Oilfield Company yase-China National Petroleum Corporation. Inhloso yayo ukuhlinzeka ngomthombo ozinzile nothembekile wegesi ye-hydrogen ehlanzekile kakhulu yokusabela kwe-hydrogenation.

Le phrojekthi isebenzisa inqubo yokulungisa umusi we-hydrocarbon elula ehlanganiswe nobuchwepheshe bokuhlanza i-pressure swing adsorption (PSA), enekhono lokukhiqiza i-hydrogen eliphelele elingu-2×10⁴Nm³/h.

Lesi sitshalo sisebenzisa igesi yemvelo njengezinto zokusetshenziswa, ezidlula ekususweni kwe-sulfurization, ekuguqulweni nasekushintsheni ukuze kukhiqizwe igesi yokwenziwa ecebile nge-hydrogen.

Ngemuva kwalokho, ihlanzwa ibe yigesi ye-hydrogen ehlanzekile kakhulu engaphezu kuka-99.9% ngohlelo lwe-PSA olunemibhoshongo eyisishiyagalombili.

Umthamo wokukhiqiza i-hydrogen oklanyelwe leyunithi ungama-Nm³ angu-480,000 ngosuku, kanti izinga lokubuyisa i-hydrogen leyunithi ye-PSA lidlula ama-85%.

Ukusetshenziswa kwamandla okuphelele kwesitshalo kuphansi kunesilinganiso semboni.

Isikhathi sokufakwa endaweni siyizinyanga ezingu-8, futhi sisebenzisa umklamo we-modular kanye nokuhlanganiswa kwangaphambili kwefektri, okunciphisa kakhulu isikhathi sokwakhiwa endaweni.

Le phrojekthi yaqedwa futhi yaqala ukusebenza ngo-2019, futhi ibilokhu isebenza kahle kusukela ngaleso sikhathi. Ihlinzeka ngegesi ye-hydrogen esezingeni eliphezulu yeyunithi ye-hydrogenation yefektri yokuhluza, iqinisekisa ukuthuthukiswa kwekhwalithi yomkhiqizo wedizili ngempumelelo.
