Isikhuthazi sokushintsha kwezinga lokushisa eliphansi:

Isicelo

I-CB-5 kanye ne-CB-10 zisetshenziselwa ukuguqulwa kwezinqubo zokwenziwa kanye nokukhiqizwa kwe-hydrogen

Ukusebenzisa amalahle, i-naphtha, igesi yemvelo kanye negesi yensimu kawoyela njengezinto zokudla, ikakhulukazi kuma-converter okushisa aphansi e-axial-radial.

Izici

I-catalyst inezinzuzo zomsebenzi ekushiseni okuphansi.

Ubuningi obuphansi be-bulk, ubuso be-Copper ne-Zinc obuphezulu kanye namandla angcono okusebenza komshini.

I-ZnO desulfurization Catalyst enekhwalithi ephezulu kanye nentengo yokuncintisana

I-HL-306 iyasebenza ekususeni i-sulfurization yamagesi okuqhekeka kwezinsalela noma i-syngas kanye nokuhlanzwa kwamagesi okuphakelayo

Izinqubo zokwenziwa kwezinto eziphilayo. Ifanele ukusetshenziswa kwezinga lokushisa eliphakeme (350–408°C) kanye neliphansi (150–210°c).

Ingaguqula isibabule esilula se-organic ngenkathi imunca isibabule esingaphili emgudwini wegesi. Ukusabela Okuyinhloko kwe-

Inqubo yokususa i-sulfurization imi kanje:

(1) Ukusabela kwe-zinc oxide ne-hydrogen sulfide H2S+ZnO=ZnS+H2O

(2) Ukusabela kwe-zinc oxide nezinye izakhi zesulfure ezilula ngezindlela ezimbili ezingenzeka.

4. Isimo Sokusebenza Esijwayelekile

I-feedstock: igesi yokwenziwa, igesi yasensimini kawoyela, igesi yemvelo, igesi yamalahle. Ingalapha ukugeleza kwegesi nge-sulfur engaphili njengoba iphakeme kakhulu

njenge-23g/m3 enezinga lokuhlanzwa elanele. Ingahlanza nokugeleza kwegesi ngamaphesenti afinyelela ku-20mg/m3 alula kanjalo

isibabule esiphilayo njenge-COS kuya ngaphansi kuka-0.1ppm.

5. Iyalayisha

Ukujula kokulayisha: Kunconywa i-L/D ephezulu (min3). Ukucushwa kwama-reactor amabili ochungechungeni kungathuthukisa ukusetshenziswa

ukusebenza kahle kwe-adsorbent.

Inqubo yokulayisha:

(1) Hlanza i-reactor ngaphambi kokulayisha;

(2) Beka amagridi amabili angenasici anosayizi omncane we-mesh kune-adsorbent;

(3) Layisha ungqimba lwe-100mm lwama-Φ10—20mm aphikisayo kumagridi angenasici;

(4) Vimbela i-adsorbent ukuze ususe uthuli;

(5) Sebenzisa ithuluzi elikhethekile ukuqinisekisa ukusatshalaliswa ngokulinganayo kwe-adsorbent embhedeni;

(6) Hlola ukufana kombhede ngesikhathi sokulayisha. Uma kudingeka ukusebenza kwe-inside-reactor, kufanele kufakwe ipuleti lokhuni ku-adsorbent ukuze umqhubi ame phezu kwalo.

(7) Faka igridi engagqwali enosayizi omncane we-mesh kune-adsorbent kanye nesendlalelo esingu-100mm sama-Φ20—30mm refractory sphere phezulu kombhede we-adsorbent ukuze kuvinjelwe ukungena kwe-adsorbent futhi kuqinisekiswe

ukusatshalaliswa okufanayo komfula wegesi.

6. Ukuqala ibhizinisi

(1) Shintsha uhlelo nge-nitrogen noma amanye amagesi angasebenzi kuze kube yilapho ukugcwala komoya-mpilo kugesi kungaphansi kuka-0.5%;

(2) Fudumeza umfudlana wokudla nge-nitrogen noma igesi yokuphakelayo ngaphansi kwengcindezi ezungezile noma ephakeme;

(3) Isivinini sokushisa: 50°C/h kusukela ekushiseni kwegumbi kuya ku-150°C (nge-nitrogen); 150°C amahora ama-2 (uma indawo yokushisa isetshenziswa

ishintshelwe kugesi wokudla), 30°C/h ngaphezu kuka-150°C kuze kube yilapho izinga lokushisa elidingekayo selifinyelelwe.

(4) Lungisa ingcindezi kancane kancane kuze kube yilapho ingcindezi yokusebenza ifinyelelwe.

(5) Ngemva kokushisa kwangaphambilini kanye nokuphakama kwengcindezi, uhlelo kufanele luqale lusebenze ngomthwalo oyingxenye amahora angu-8. Bese uphakamisa

umthwalo kancane kancane lapho ukusebenza kuzinzile kuze kube yilapho kusebenza ngokugcwele.

7. Ukuvala

(1) Ukunikezwa kwegesi (uwoyela) okuvala ngokushesha.

Vala amavalvu okungena nawokuphuma. Gcina izinga lokushisa kanye nengcindezi. Uma kudingeka, sebenzisa i-nitrogen noma i-hydrogen-nitrogen

igesi ukuze kugcinwe ingcindezi ukuze kuvinjelwe ingcindezi engemihle.

(2) Ukushintsha kwe-desulfurization absorbent

Vala amavalvu okungena nawokuphuma. Yehlisa kancane kancane izinga lokushisa kanye nengcindezi ukuze kube sesimweni sezulu. Bese uhlukanisa

i-reactor yokususa i-sulfurization ohlelweni lokukhiqiza. Buyisela i-reactor ngomoya kuze kube yilapho kufinyelelwa ukugcwala kwe-oxygen okungu->20%. Vula i-reactor bese ukhulula i-adsorbent.

(3) Ukulungiswa kwemishini (ukulungiswa)

Landela inqubo efanayo njengoba kuboniswe ngenhla ngaphandle kokuthi ingcindezi kufanele yehliswe ku-0.5MPa/10min kanye nokushisa.

kwehliswe ngokwemvelo.

I-adsorbent engalayishwanga kufanele igcinwe ngezendlalelo ezihlukene. Hlaziya amasampula athathwe kungqimba ngayinye ukuze uthole

isimo kanye nempilo yesevisi ye-adsorbent.

8. Ezokuthutha kanye nesitoreji

(1) Umkhiqizo we-adsorbent upakishwe emiphongolweni yepulasitiki noma yensimbi ene-plastic lining ukuvimbela umswakama kanye namakhemikhali

ukungcola.

(2) Ukuwa, ukushayisana kanye nokudlidliza okunamandla kufanele kugwenywe ngesikhathi sokuthuthwa ukuze kuvinjelwe ukugaywa kwe-

i-adsorbent.

(3) Umkhiqizo ongenisa i-adsorbent kufanele uvinjelwe ukuthi ungathintani namakhemikhali ngesikhathi sokuthuthwa nokugcinwa kwawo.

(4) Umkhiqizo ungagcinwa iminyaka emi-3-5 ngaphandle kokuwohloka kwezakhiwo zawo uma uvalwe kahle.
