Jiilka hydrogen ee dib u habeynta uumiga waa in la sameeyo falcelinta kiimikaad ee gaasta dabiiciga ah ee la cadaadiyo iyo la nadiifiyey iyo uumiga dib-u-habeeye gaar ah oo buuxinaya kicinta oo uu dhaliyo gaaska wax ka beddelka ee H₂, CO₂ iyo CO, u beddel CO ee gaasaska dib-u-habaynta CO₂ ka dibna soo saara CO₂ U qalma H₂ oo ka yimid gaasaska dib-u-habaynta ee cadaadiska luminta adsorption (PSA).
Haydaroojiinka habka dib-u-habaynta uumiga inta badan waxa ka mid ah afar tillaabo: pretreatment gaasta ceeriin, dib u habaynta uumiga gaaska dabiiciga ah, wareejinta carbon monoxide, hydrogen sifaynta.
Tallaabada ugu horreysa waa pretreatment alaabta ceeriin, taas oo inta badan loola jeedaa desulfurization gaaska ceeriin, hawlgalka habka dhabta ah guud ahaan isticmaalaa cobalt molybdenum hydrogenation taxane zinc oxide sida desulfurizer ah si loogu badalo baaruud organic ee gaaska dabiiciga galay baaruud inorganic ka dibna ka saar.
Talaabada labaad waa dib u habaynta uumiga gaaska dabiiciga ah, kaas oo isticmaala nikkel katalyst ee dib-u-habeeyaha si uu ugu beddelo alkanes ee gaasta dabiiciga ah gaas feedstock ah oo qaybaha ugu muhiimsan ay yihiin carbon monoxide iyo hydrogen.
Talaabada saddexaad waa kaarboon moono-ogsaydh shift. Waxa ay la falgashaa uumiga biyaha marka uu jiro wax kicinaya, iyada oo soo saarta hydrogen iyo carbon dioxide, oo ay hesho gaas shift ah oo inta badan ka kooban hydrogen iyo carbon dioxide.
Talaabada ugu dambeysa waa in la nadiifiyo hydrogen, hadda nidaamka nadiifinta hydrogen ee inta badan la isticmaalo waa nidaamka kala soocida sifaynta cadaadiska (PSA). Nidaamkani wuxuu leeyahay sifooyinka isticmaalka tamarta hooseeya, habka fudud iyo nadiifinta sare ee hydrogen.
Tilmaamaha Farsamo ee Soo saarista Gaaska Dabiiciga ah
1. Wax-soo-saarka Hydrogen-ka ee loo maro Gaaska Dabiiciga ah waxa uu leeyahay faa'iidooyinka miisaanka wax-soo-saarka haydaroojiin weyn iyo tignoolajiyada qaan-gaadhka ah, waana isha ugu weyn ee hydrogen hadda.
2. Unugga abuuritaanka gaaska dabiiciga ah ee hydrogen waa is dhexgalka sare, otomaatig sarreeya waana sahlan tahay in la shaqeeyo.
3. Soo saarista hydrogen ee dib u habeynta uumiga waa kharash hawlgal oo jaban iyo muddo gaaban oo soo kabasho ah.
4. Warshad Soo saarta Hydrogen-ka ee TCWY Isticmaalka shidaalka iyo qiiqa sii daaya ee ay PSA ka saartay taageeridda gubashada.
* Habka soo saarista ogsijiinta ee VPSA waxa ay fulisaa naqshad “la habeeyey” iyadoo loo eegayo joogga kala duwan ee isticmaalaha, xaaladaha saadaasha hawada, cabbirka aaladda, nadiifnimada ogsajiinta (70% ~ 93%).
1. H2 Dib-u-warshadaynta ka soo cusboonaatay gaaska qani ku ah H2 (PSA-H2)
Daahirsanaanta: 98% ~ 99.999%
2. CO2 Kala soocida iyo nadiifinta (PSA - CO2)
Daahirsanaanta: 98 ~ 99.99%.
3. Kala-soocidda iyo nadiifinta CO (PSA- CO)
Daahirsanaanta: 80% ~ 99.9%
4. Ka saarida CO2 (PSA - CO2 saarista)
daahirnimo: <0.2%
5. PSA – C₂+ Ka saarida
