Ọrụ a bụ ngalaba mgbake gas ọdụ styrene nke AIR LIQUIDE (Shanghai Industrial Gas Co., Ltd.) nyere. Ọ na-eji teknụzụ nnabata nrụgide nke Skid-mounted pressure swing adsorption iji weghachite hydrogen site na gas ọdụ mmepụta styrene. Ike nhazi nke unit ahụ bụ 2,500 Nm³/h, na-ejikwa gas ọdụ site na osisi styrene. Isi ihe dị na gas a bụ hydrogen, benzene, toluene, ethylbenzene, na ihe ndị ọzọ dị ndụ. Sistemụ ahụ na-anabata usoro ejikọtara ọnụ nke "ọgwụgwọ tupu + PSA". Ngalaba ọgwụgwọ tupu oge eruo gụnyere usoro dịka condensation na adsorption, na-ewepụ ngwakọta benzene na gas ọdụ ma na-echebe ihe na-eme ka PSA na-abanye. Ngalaba PSA na-eji nhazi ụlọ elu isii, yana ịdị ọcha hydrogen ngwaahịa ruru 99.5%, yana ọnụego mgbake hydrogen gafere 80%. Olu mgbake hydrogen kwa ụbọchị bụ 60,000 Nm³.
