Ucwaningo Lwecala | Ukubhekana Nezimo Zokusebenza Ezinzima Kakhulu — Uhlelo Lokusabela Kwe-FCC–Ukuvuselelwa

Uketshezi Ukuqhekeka kwe-Catalytic (FCC) ingenye yezinqubo zokucwenga zesibili ezibaluleke kakhulu ezitshalweni zanamuhla zamakhemikhali kaphethiloli. Iguqula uwoyela osindayo ube imikhiqizo kawoyela okhanyayo onenani eliphezulu kanye nokudla kwamakhemikhali. Ingqikithi yale nqubouhlelo lokusabela-ukuvuselelwa, lapho kushisa khona Izinhlayiya ze-Catalyst isitokwe sokudla esithintanayo ku-reactor ye-riser ukuze sakhe umhwamuko kawoyela olula. I-catalyst ephekiwe ithunyelwa ku-regenerator ukuze ishiswe futhi ivuselelwe ngaphambi kokuba ibuyiselwe emuva ekusebenzeni.

Uhlelo luhlanganisa nesigaba sokuhlukaniswa, isigaba sokumuncwa–ukuzinza, kanye neyunithi yokutakula amandla egesi yomoya ongcolile — konke kubalulekile ekuthuthukiseni isivuno somkhiqizo kanye nokusebenza kahle kwamandla.

Iqiniso Elibuhlungu: Izinga Lokushisa Eliphezulu, Umfutho Ophezulu, Ukuguguleka Kwe-Catalyst kanye Nokugqwala Okukhulu

Kumayunithi e-FCC, ama-valve asebenza ngaphansi kwezimo ezinzima kakhulu. Ngokwesiko, izindawo eziningi zokucwenga zazithembele kakhulu emikhiqizweni engeniswa kwamanye amazwe efana nalokhu:

INeles (eFinland) – I-Ceramic Ball Valves

I-MOGAS (USA) - Ifakwe insimbi I-Ball Valves

I-KITZ ne-NBV (eJapane) – Amavalvu asebenza kahle kakhulu anezinsika zensimbi

Kodwa lawa ma-valve avame ukuhlushwa yi:

Ukuguguleka kwe-Catalyst

Ukugqwala okushisa okuphezulu

Ukupheka nokuvaleka

Ukuqina nokunamathela kwe-torque

Impilo yesevisi emfushane

Icala 1 - I-Sinopec Refining Subsidiary

Njengeyunithi eyinhloko yokukhiqiza yale ndawo yokuhluza, uhlelo lwayo lwe-FCC ludinga ukuthembeka okungavamile kuma-valve—ukumelana Izinga Lokushisa Eliphezulu, ingcindezi, ukuguguleka komhlabathi, kanye nemithombo yezindaba egqwalisayo.

Indawo yokucwenga yayilokhu isebenzisa isikhathi eside I-MOGAS efakwe insimbi I-Ball Valves, kodwa ukwehluleka okuphindaphindiwe kwenzeke ngenxa yalokhu:

Ukuguguleka kwe-catalyst okushisa okuphezulu

Ukuqhekeka kwangaphakathi kanye nokuguqulwa

Ukubilisa okuholela ekunamatheleni nasekubanjweni

Impilo yesevisi ephezulu kakhulu:

Ngemva kokushintshela ku- Izinto zobumba ze-KOWOVI-valve ye-Cs, impilo yesevisi yevalvu ikhuphuke yaba: Iminyaka emi-3— ukuthuthukiswa okungu-3 ×.

Icala 2 – Inkampani Yamakhemikhali Yamandla iShaanxi Yanchang

Njengenkampani yamakhemikhali ehlanganisiwe yamalahle-uwoyela-negesi, iyunithi yayo ye-FCC idlala indima ebalulekile ekukhiqizeni imikhiqizo kawoyela olula.

Ukwamukela isu le- "imikhiqizo engenisiwe njengemikhiqizo eyinhloko, yasekhaya ephezulu njengesengezo,"inkampani yenze izivivinyo zokuqhathanisa zesikhathi eside phakathi:

Kungenisiwe Kuzoamavalvu ebhola le-ceramic

Yasekhaya I-KOWOVamavalvu ebhola le-ceramic

Imiphumela:

Kokubili kufeziwe Izinyanga ezingu-18+impilo yesevisi

I-KOWOV yehlise izindleko zokuthenga ngo- 40–50%

Isikhathi sokulethwa sifinyeziwe kusukela ku- Izinyanga ezi-4–6 → Izinyanga ezi-1–2

Izindleko zempahla yezingxenye ezisele zincishisiwe 50%

Isikhathi sokuphendula ngokwehluleka sincishisiwe 60%

Izindleko ze-O&M sezizonke zincishisiwe 50%

Ukufakwa esikhundleni kwendlu kwaqaliswa kancane kancane kuso sonke isitshalo.

Icala 3 - Esinye Isisekelo Se-Sinopec Petrochemical

Le nkampani enkulu yokucwenga eyayithembele kuyo ngaphambili I-KITZ ne-NBVamavalvu ebhola ahlala ngensimbi ezingxenyeni ezibalulekile ze-FCC, okuhlanganisa:

Uhlelo lokuvuselela nokusabela

Isigaba sokuhlukanisa

Iyunithi yokutakula amandla egesi yomoya (i-FGRU)

Ngemva kokushintshela ku- Amavalvu e-ceramic e-KOWOV, imiphumela yayiyi:

Izindleko zokuthenga ama-valve zincishisiwe ≈35%

Izinga lokushintshana kwezingxenye ezisele likhuphukile 40%

Umjikelezo wokulungisa omaphakathi ufinyeziwe 30%

Ukwamukelwa Kwevalvu Yesitsha: Ukuguqula Ukuthembeka Kwe-FCC Nokusebenza Kahle Kwezindleko

I-FCC iyitshe elibalulekile ekukhiqizweni kukaphethiloli kanye nokuhlinzekwa kwe-petrochemical feedstock. Njengoba iShayina iqhubekela phambili ukuhlanganiswa kokucwenga-amakhemikhali, imisebenzi eluhlaza kanye ne-carbon ephansi, futhi ukukhiqiza okuhlakaniphile, indima yamavalvu asebenza kahle iba yinto ebaluleke kakhulu.

Ukwanda kobuchwepheshe bama-valve e-ceramic asekhaya — obumelelwa yi-KOWOV — kuyashesha:

Ukwenziwa kwendawo

Ukuthuthukiswa kokuthembeka

Ukwehliswa kwezindleko

Ukusebenza okuhlakaniphile

Ukukhiqizwa kwe-FCC okuhlala isikhathi eside nokuzinzile

Amavalvu e-ceramic aphezulu aseba yindinganiso entsha yezinhlelo zokusebenza ze-FCC ezidinga kakhulu.
