An kana Yadda Maimaitar da Duk'ar Karamin Zafi Yake Yaɗu? Wadannan 4 Dangantaka Masu Siffar Da Kana Da Zama Don Samun Shen

Yadda takaitaccen kisan kwalliya ya tabbatar da zama da tattalin arzikin al'adu
A cikin birnin hidrokarakiri, akwai karamin karamin kisan kwalliya a gasar harkokin hidrogin, inda yadda takaitaccen kisan kwalliya ya tabbatar da zama da tattalin arzikin harkokin hidrogin. Don birni mai hidrokarakiri na musamman, tattalin arzikin harkokin hidrogin ya kunshi sarrafa 15%–30% daga jami'a tattalin arzikin al'adu. Saboda haka, yadda takaitaccen kisan kwalliya a cikin kisan kwalliya na takamaya ya tabbatar da zama da tattalin arzikin jami'an al'adu, kuma yadda mafi takaitaccen ya taimakawa da wuce abincin rayuwa.

Kisan kwalliyar ke gudanar da harsuna da damu
Birnin hidrokarakiri ke gudanar da harsuna da damu, a cikin yanayi na hidrogin da damu, wanda ya ba da ma'ana mai yawa ga adabin zarfi da rawa'i. A wasu halayin hada, yana bukatar da a haɗa tsaro na harsuna a baki daya da 0.7 MPa/min ko 2.1 MPa/min. A lokacin hakan, kisan kwalliya na takamaya ya haɗa tsaro da kyau, sannan faren mutanen yana faruwa da kyau, wanda yake iya haifar da kafin da lafiya ko kafin da rabi.

Kyakkyawan al'adu ya zama da muhimmanci masu sauki
Da yawan ci gaba na birnin da suka fiye a ranar, kisan kwalliya na takamaya suna zama da kyakkyawan al'adu, wanda ya zama da muhimmanci masu sauki. Don kisan kwalliyar na ringin karamin karamin, birni da tsarin kilomita 1600 mm ke ana cewa suna da kyakkyawan al'adu, wanda yake iya ba da muhimmiyar sauki. Tsari mai ruwa an buga da kyau, kuma ana buƙata da sauki mai yawa, da kuma ana iya haifar da kafin da lafiya na gida. A shekarun biyu, an samu kisan kwalliyar na ringin karamin karamin da tsarin φ1800 mm, amma muhimmin saukin cin za suka duba, kuma yadda ake iya haifar da kafin da lafiya na gida ya zama da yawa.

Yadda takaitaccen nitrogen, sulfur, da wasu manyan abubuwa ke gudanar da kafin da lafiya da kafin da rabi
Yadda takaitaccen nitrogen a cikin abincin birnin hidrokarakiri ana cikin sarrafa 500–2000 μg/g. Ammonia a cikin tsari mai haɗa ya haɗa da hydrogen sulfide ko karamin karamin hydrogen chloride don samun ammonium salts. Tsari mai haɗa ammonium salt a cikin birnin hidrokarakiri ana cikin sarrafa 160°C zuwa 210°C. Yadda da take da ammonium da ya haɗa tsaro, yadda da take da tsari mai haɗa. Kuma ammonium chloride ya haɗa tsaro da kyau da ammonium bisulfide.

An buƙatar da kofin ruwan da kofin ruwan daidai don hauƙar ammonium salts da kafin da haifar da kafin da lafiya da kafin da rabi wanda zai iya haifar da kafin da lafiya na gida ko kafin da rabi a cikin kisan kwalliya. Abincin birnin hidrokarakiri zai iya kasance deasphalted oil, FCC diesel, coker diesel/wax oil, straight-run diesel/wax oil, kamar haka. Tsari mai haɗa kisan kwalliyar na abinci da tsari mai haɗa ana cikin sarrafa 190°C zuwa 440°C. Aromatics, resins, da asphaltenes a cikin abinci suka haifar da kafin da rabi a cikin kisan kwalliya na takamaya—the higher the impurity content, the more likely coking occurs. Coking reduces heat transfer efficiency and increases pressure drop; in severe cases, it can force the unit to shut down.
