Sulfur-recovery units nyob rau hauv cov roj refining thiab thee-chemical industries feem ntau siv cov txheej txheem Claus kom rov qab cov tshuaj sulfur. Txwv tsis pub los ntawm cov tshuaj sib npaug, cov pa roj av los ntawm Claus chav tsev tseem muaj cov sulfur ntau heev -dioxide, carbonyl sulfide, carbon disulfide thiab lwm cov organic sulfur compounds. Cov khoom no tsis tuaj yeem raug tso tawm ncaj qha kom ua tau raws li cov qauv emission. Yog li ntawd, tus Tsov tus tw-gas hydrogenation chav kho mob yuav tsum tau nruab los hloov ntau yam tsis yog-hydrogen-sulfide sulfur compounds rau hauv hydrogen sulfide, uas yog tom qab ntawd rov ua dua los ntawm amine absorption kom txaus siab ib puag ncig- tiv thaiv emission.
Nyob rau hauv tag nrho tus Tsov tus tw - cov txheej txheem kho roj, hydrogenation - hloov pauv catalyst ua lub hauv paus txiav txim siab tag nrho kev ua haujlwm ntawm lub tsev. Thaum lub sijhawm ua haujlwm tiag tiag, chav tsev tau ntsib nrog cov teeb meem ua tau zoo xws li kev hloov pauv ntawm kev ua haujlwm, qhov sib txawv ntawm qhov kub thiab txias ntawm cov khoom sib xyaw ua ke, uas teeb tsa ntau yam kev xav tau rau kev ua tiav ntawm cov catalysts. Ntawm ib sab, cov khoom siv hluav taws xob yuav tsum xa cov khoom siv hluav taws xob tsawg- qhov kub thiab txias ua kom tiav hydrogenation txo thiab cov organic-sulfur hydrolysis cov tshuaj tiv thaiv nyob rau hauv qhov kub ua hauj lwm me me, thiaj li txiav cov cua sov siv ntawm chav tsev. Ntawm qhov tod tes, lawv xav tau cov cheeb tsam tshwj xeeb txaus thiab qhov pore ntim kom ntseeg tau tias kev faib tawm tsis sib xws ntawm cov khoom siv rau kev tuav cov khoom noj nrog cov txheej txheem nyuaj. Lub caij no, lub zog ua haujlwm zoo heev yuav tsum tau tiv thaiv cov pa roj- ntws yaig, txo qis qis, ua kom lub neej ua haujlwm catalyst thiab txo qhov kev kaw - hloov zaus.
Ntau qhov kev ua haujlwm hauv kev lag luam qhia tau hais tias kev xaiv cov khoom siv tsis raug cai yuav ua rau cov organic tsis tiav -sulfur hloov dua siab tshiab, kev ua haujlwm sai sai thiab nce siab hauv txaj siab poob. Cov teeb meem no yuav ncaj qha ua rau tus Tsov tus tw ntau dhau - tso pa tawm thiab ua haujlwm nce ntxiv - thiab - kev tu lub nra rau cov lag luam.Shandong Xunda TshuajKev lag luamGroup Co., Ltd.tau ntev tau koom nrog R&D ntawm sulfur- rov qab catalysts. Nws tau tsim tshwj xeeb catalysts rau sulfur tail-gas hydrogenation kev pab cuam nrog tas li optimization ntawm cov cab kuj thiab active-cov ntsiab lus piv, uas muaj feem xyuam rau sulfur- rov qab tus Tsov tus tw- roj kho units nyob rau hauv txawv txawv teb chaws ua hauj lwm tej yam kev mob.
Los ntawm qhov kev xav ntawm kev lag luam thoob ntiaj teb kev lag luam, ib puag ncig - cov cai tiv thaiv thoob ntiaj teb tau nce zuj zus. Thaum ua haujlwm sulfur- rov qab units, cov lag luam tsis tsuas yog nrhiav tag nrho cov sulfur- rov qab ua haujlwm. Kev saib xyuas ntau dua yog them rau cov catalysts 'ntev- lub sijhawm ua haujlwm ruaj khov, ua haujlwm siab tiv thaiv kev ua haujlwm- qhov hloov pauv hloov pauv thiab tag nrho- lub neej- voj voog tus nqi. Txhim khu kev ua tau zoo ntawm hydrogenation- ntu kev hloov pauv tsis tsuas yog ua kom lub tsev ua tau raws li cov qauv emissions, tab sis kuj tseem ua raws li txoj hauv kev tseem ceeb rau cov lag luam kom paub cov khoom siv hluav taws xob rov ua dua thiab txhim kho cov txiaj ntsig kev lag luam tag nrho.
