Maitiro ekugadzira hydrogen gasi rechisikigo
Kufamba kwekugadzirwa kwehydrogen kubva mugasi rechisikigo kune zvikamu zvina: kugadziriswa kwegasi rekudyisa, kushandurwa kwemhepo, kushandurwa kweCO2 uye kuchenesa hydrogen.
(1) Chigadziko chekugadzirisa gasi rekudyisa chinoshandiswa zvakanyanya pakubvisa sarufa mugasi rechisikigo, uye MnO neZnO desulfurizers zvinoshandiswa kubvisa H2S neSO2. Kugona kwekugadzira gasi rekudyisa kwakakura, saka compressor hombe ye centrifugal inosarudzwa kana uchidzvanya gasi rekudyisa.
(2) Chigadziko chekushandura mhute. Mhute yemvura inoshandiswa se oxidant kushandura mahydrocarbon pasi pesimba re nickel catalyst kuti iwane gasi rekushandura rekugadzira hydrogen. Rudzi uye chimiro che reformer zvine hunhu hwazvo, uye chimiro, thermal compensation mode uye fixing mode ye collectors dzegasi repamusoro nerezasi zvakasiyanawo. Kunyangwe ma heat exchangers ari muchikamu che convection akaiswa zvakasiyana, process operation parameters ye high-temperature conversion uye water carbon ratio yakaderera inoshandiswa mu steam conversion unit, iyo inobatsira kuvandudza kudzika kwekushandura uye kuchengetedza kushandiswa kwezvinhu zvakabikwa.
(3) Chikamu chekuchinja CO. Gasi rinotumirwa kubva kumugadziri rine huwandu hwakati hweCo. basa rekushandura nderekuita kuti co iite pamwe chete nemhepo kuti igadzire CO2 neH2 pamberi pechinokonzeresa. Zvichienderana nekupisa kwekushandura, maitiro ekushandura anogona kukamurwa kuita shanduko yekupisa kwakanyanya (350 ~ 400 ℃) uye shanduko yekupisa kwepakati (pasi pe300 ~ 350 ℃). Mumakore achangopfuura, nekuda kwekusimbiswa kwekuchengetedzwa kwezviwanikwa, maitiro ekushandura ematanho maviri ekuchinja kweCO2 pakupisa kwakanyanya uye kushandurwa kwekupisa kwakaderera akagamuchirwa mukugadzirisa maitiro echikamu chekushandura, kuitira kuderedza kushandiswa kwezvinhu zvakagadziriswa.
(4) Unit yekuchenesa Hydrogen. Mukuita uku, kambani yega yega inogadzira hydrogen yakashandisa pressure swing adsorption (PSA) cleansing and separation system ine simba shoma kuti itsive decarbonization and cleansing system uye methane chemical process ne simba rakawanda, kuitira kuti chinangwa chekuchengetedza simba chibudirire uye kurerutsa maitiro acho, uye hydrogen ine hutsanana hunosvika 99.9% inogona kuwanikwa panobuda hydrogen.
