Tekinoroji maitiro

Natural gasi compression uye kutendeuka

Gasi rechisikigo riri kunze kwemuganho webhatiri rinotanga kudzvanywa kusvika 1.6Mpa necompressor, rozopiswa kusvika pa380 ℃ nefeed gasi preheater muchikamu checonvection chechoto chekuvandudza bhatiri, uye inopinda mudesulfurizer kubvisa sarufa mugasi rekudya. pazasi 0.1ppm. Iyo desulfurized feed gasi uye process steam (3.0mpaa) Gadzirisa iyo yakasanganiswa gasi preheater zvinoenderana neiyo otomatiki kukosha kweH2O / ∑ C = 3 ~ 4, kuwedzera preheat kusvika kunopfuura 510 ℃, uye zvakaenzana pinda pombi yekutendeuka kubva kumusoro kwegasi kuunganidzwa. pombi huru uye yekumusoro pigtail pombi. Mune catalyst layer, methane inobata neutsi kugadzira CO neH2. Kupisa kunodiwa pakushandura methane kunopiwa nemusanganiswa wemafuta wakapiswa pamoto wepasi. Tembiricha yegasi rakashandurwa kubva muvira reformer i850 ℃, uye tembiricha yepamusoro inoshandurwa kuita tembiricha yakakwira. Iyo kemikari gasi inopinda mudivi rechubhu yemarara inopisa bhailer kuti ibudise 3.0mpaa yakazara mutsi. Iyo tembiricha yekutendeuka gasi kubva mumarara inopisa boiler inodonha kusvika 300 ℃, uye ipapo gasi rekushandura rinopinda mubhailer feed yemvura preheater, shanduko gasi remvura inotonhorera uye kushandura gasi separator yemvura kuti iparadzanise iyo condensate kubva mukuita condensate, uye iyo process gasi inotumirwa kuPSA.

Iro gasi rechisikigo sehuni inosanganiswa nekumanikidza swing adsorption desorption gasi, uye ipapo vhoriyamu yehutsi gasi mumafuta egasi preheater inogadziriswa zvinoenderana nekupisa kwegasi pakubuda kwevira reformer. Mushure mekugadzirisa kuyerera, gasi remafuta rinopinda mumoto wepamusoro wekupisa kuti upe kupisa kuvira reformer.
Iyo mvura yakasvibiswa inofanopiswa neyakaiswa mvura preheater uye boiler feed yemvura preheater uye inopinda ne-chigadzirwa chiutsi che flue gasi tsvina boiler uye kugadzirisa gasi tsvina boiler.
Kuti iite kuti iyo boiler yekudyisa mvura isangane nezvinodiwa, shoma shoma yephosphate solution uye deoxidizer ichawedzerwa kuvandudza kuyera nekuora kwemvura yeboiler. Iyo dhiramu inoramba ichiburitsa chikamu chemvura yekuboiler kudzora iyo yakazara yakanyungudika yakanyungudika yemvura yekuboiler mudhiramu.

Pressure swing adsorption

PSA ine shongwe shanu dzekushambadza. Imwe adsorption tower iri mune adsorption state chero nguva. Izvo zvikamu zvakadai semethane, carbon dioxide uye carbon monoxide mukushandura gasi zvinogara pamusoro peiyo adsorbent. Hydrogen inounganidzwa kubva pamusoro peiyo adsorption tower senge isiri-adsorption zvikamu uye inotumirwa kunze kwemuganhu. Iyo adsorbent yakazadzwa nezvikamu zvetsvina inobviswa kubva kune adsorbent kuburikidza nedanho rekuzvarwa patsva. Kana yaunganidzwa, inotumirwa kuchoto chinochinja sehuni. Matanho ekuvandudzwa kweiyo adsorption shongwe inoumbwa nematanho gumi nemaviri: kudonha kweyunifomu yekutanga, kudonha kweunifomu yechipiri, kudonha kweyunifomu yechitatu, kubuda kumberi, kubuda kunodzosera, kubhururuka, kusimuka kweyunifomu yechitatu, kusimuka kweyunifomu yechipiri, kusimuka kweyunifomu yekutanga uye kusimuka kwekupedzisira. Mushure mekuzvarwa patsva, iyo adsorption tower inokwanisa zvakare kurapa yakashandurwa gasi uye kugadzira haidrojeni. Iwo mashanu adsorption shongwe anochinjana kuita matanho ari pamusoro apa kuti ave nechokwadi chekuramba achirapwa. Chinangwa chekushandura gasi uye kuramba uchigadzira hydrogen panguva imwe chete.

Device maitiro

Iyo yakazara skid yakaiswa dhizaini inoshandura yechinyakare pa-saiti yekuisa modhi. Kuburikidza nekugadzirisa, kugadzirwa, pombi uye skid kuumba mukambani, iyo yese maitiro ekugadzira kutonga kwezvinhu, kuona kukanganisa uye kuyedza kumanikidza mukambani inozadzikiswa, iyo inogadzirisa zvakanyanya njodzi yekudzora mhando inokonzerwa nekuvakwa kwemushandisi pasaiti, uye zvechokwadi. inowana iyo yose hurongwa hwekutonga kwehutano.

Zvese zvigadzirwa skid zvakaiswa mukambani. Pfungwa yekugadzira mufekitari inogamuchirwa. Mushure mekupfuura iyo yekuongororwa kwefekitori, inoparadzaniswa zvinoenderana neyakagadzika disassembly scheme uye inotumirwa kunzvimbo yemushandisi kuti iunganidzwe zvakare. Iko-pa-site kuvaka vhoriyamu idiki uye kutenderera kwekuvaka kupfupi.

Dhigirii re automation rakakwira zvakanyanya. Kushanda kwechishandiso kunogona kunyatsotariswa otomatiki uye kudzorwa kuburikidza neyepamusoro sisitimu, uye kiyi data inogona kuiswa kune yegore server munguva chaiyo yekuonekwa kure, kuitira kuti uone iyo isina kurongwa manejimendi pasaiti.

Kufamba kwechigadzirwa kwakasimba zvikuru. Zvinoenderana nemamiriro chaiwo eiyo purojekiti, mudziyo unogona kutamiswa kuenda kune imwe nzvimbo uye kushandiswa mushure mekuiswa skid zvakare, kuitira kuti uone kushandiswazve kwemidziyo uye kuve nechokwadi chekubatsira kwakanyanya kwekukosha kwemidziyo.

Zvinoenderana neiyo hydrogen kudiwa kweiyo hydrogenation chiteshi, ita yakajairwa dhizaini dhizaini uye dhizaini dhizaini yekubatanidza zvinoenderana nemodule yekugadzira kuti uone kugadzirwa kwakamisikidzwa kwezvigadzirwa uye kuumba zvakajairwa zvakatevedzana zvigadzirwa, zviri nyore kune mushandisi manejimendi emidziyo, yakajairika spare. zvikamu uye kuderedza mutengo wekushanda kwechikwata.

Kupfupisa, skid yakamisikidzwa gasi rechisikigo hydrogen kugadzira unit ndiyo yakanyatsokodzera hydrogen sosi yekushandisa mune ramangwana rehydrogenation station.
