Kudyisa gasi rinorema hydrocarbon kubvisa unit
1）Sistimu basa
Heavy hydrocarbons uye anonhuwirira hydrocarbons mugasi rechisikigo anoomesawo pane yakaderera tembiricha, saka anofanirwa kubviswa. Iyo unit inotora activated kabhoni adsorption nzira yekubvisa inorema hydrocarbons uye anonhuwirira hydrocarbons.
Muchikamu ichi, shongwe mbiri dzakafanana dzinoshandiswa kushambadza mahydrocarbons anorema uye anonhuwirira mahydrocarbon. TSA nzira inoshandiswa kuongorora mahydrocarboni anorema uye anonhuwirira mahydrocarbon mune activated carbon. Panguva imwecheteyo, condensation nzira inoshandiswa kukwenya nekuparadzanisa mahydrocarboni anorema uye anonhuwirira mahydrocarbon akabviswa kubva kune adsorbent.
2) Dhizaina paramita
Kudyisa gasi kugadzirisa simba 10×104Nm3/zuva
Adsorption pressure 4.4MPa.G
Dhizaini poindi yeinorema hydrocarbon mune yekudyisa gasi ≤ 1000ppmv
Adsorption tembiricha ~ 40 ℃
Kudzvanya patsva 4.2MPa.G
Regeneration tembiricha 180 ~ 280 ℃
Regenerative heat source yakakwira tembiricha yekutamisa mafuta
Zviri mukati meheavy hydrocarbon uye anonhuwirira hydrocarbon mugasi rakacheneswa zvichave ≤ 10ppm zvichiteerana.
3) Chikamu chekugadzirisa
Iyo mitoro yekudzora huwandu ndeye 50 ~ 110%.
4）Maitiro ekuyerera tsananguro
Gasi rechisikigo rinobva kufeed gasi rinoomesa yuniti rinotanga kupinda kubva pamusoro peiyo inorema hydrocarbon yekubvisa shongwe kuburikidza nekusiyanisa kudzvanywa kwevharuvhu. Mushure mekubvisa iyo inorema hydrocarbon kuburikidza neiyo adsorption yeiyo activated kabhoni mubhedha, inobuda kubva pasi peinorema hydrocarbon yekubvisa shongwe. Mushure mekubvisa iyo inorema hydrocarbon, zviri mukati meiyo inonhuhwirira hydrocarbon mugasi rechisikigo ndeye ≤ 10ppmv, uyezve inopinda mecury kubvisa uye guruva filtration unit.
Iyo inorema hydrocarbon yekubvisa unit ine mbiri inorema hydrocarbon yekubvisa shongwe. Mukati menguva yakapihwa adsorption cycle, imwe iri muadsorption state yekubvisa mahydrocarbon anorema mugasi rekudyisa, uye yechipiri iri mukuzvarwa patsva (kudziya uye kutonhora kuvhuvhuta) mamiriro ekubvisa anonhuwirira mahydrocarbons muakabatidzwa kabhoni. Kana iyo inorema hydrocarbon yekubvisa shongwe mune adsorption state yazara, chinja kune inorema hydrocarbon yekubvisa shongwe inopedzisa kuvandudzwa. Iyo yakazara inorema hydrocarbon yekubvisa shongwe inoteverwa nekudziya kwekuvandudza kutenderera uyezve kutonhora.
Iyo gasi yekuvandudza inowanikwa kubva kumberi kwekusiyanisa kudzvinyirira kudzora valve. Iyo gasi yekuvandudza inopinda muyakagadziridzwa gasi kupisa muchoto uye inopisa kusvika 220 ~ 280 ℃. Gasi rinopisa uye rakaoma rinobvisa mahydrocarboni anonhuhwirira muakabatidzwa kabhoni kubva kumusoro kusvika kuzasi kuburikidza nekugadzirwa patsva (kudziya) kunorema hydrocarbon yekubvisa shongwe. Gasi rekuvandudza rine ma hydrocarbons anonhuhwirira kubva kune inorema hydrocarbon yekubvisa shongwe munzvimbo yekuzvarwa patsva (kupisa) inopinda mune yekuvandudza gasi inotonhorera kuti irambe ichitonhorera, uye yobva yaparadzanisa inokwanisika yakanyungudutswa inonhuhwirira hydrocarbons mune inoparadzanisa, uye iyo yakanyungudutswa inopinda mugasi separator.
Iyo gasi kubva pamusoro pekuparadzanisa gasi rekuvandudza inopinda mushongwe yeadsorption mudunhu readsorption pamwe chete neyekudya gasi remusikirwo kuseri kwekusiyanisa kudzvanywa kwevhavhavhavha.
Kudyisa gasimercury kubvisa uye filtration unit
1）Kutsanangura tsananguro
Iro gasi rechisikigo kubva kune yekudyisa gasi rekuomesa uye rinorema hydrocarbon yekubvisa unit inopinda mu sulfur impregnated activated carbon adsorber. Mercury inopindirana nesarufa pasarufa yakagadzikwa activated kabhoni kuti ibudise mercury sulfide, iyo inoshambadzirwa paiyo activated kabhoni, kuitira kuti izadzise chinangwa chekubvisa mecury. Iyo mercury yemukati yegasi rechisikigo kubva kune mercury inobvisa isingasviki 0.01μg/Nm3.
Imwe mercury remover inogadzikwa, uye sarufa yakaiswa activated kabhoni inotsiviwa zvichienderana nekuonekwa.
Iyo sefa unit yakashongedzerwa nesefa, iyo inogona kuchinjika zvinoenderana nedata rekupikisa kuti uwane chinangwa chekusefa ma molecular sieve uye activated kabhoni guruva.
Mushure mekubviswa kweguruva, guruva zvidimbu mugasi rekudya zviri pasi pe10μm.
Iyo huru midziyo ndeye mercury remover uye guruva sefa.
2) Dhizaina paramita
