1. Xyuas kom meej tus nqi pH ntawm cov kua ua haujlwm ntawm cov tshuaj tiv thaiv hydrogenation thiab oxidation cov tshuaj tiv thaiv. Thaum siv txoj kev anthraquinone los tsim hydrogen peroxide, hydrogenation ntawm cov kua dej ua haujlwm yog ua raws li cov xwm txheej alkaline. Cov tshuaj tiv thaiv oxidation ntawm cov kua hydrogenation thiab cov extraction ntawm hydrogen peroxide yuav tsum tau nqa tawm nyob rau hauv acidic tej yam kev mob. Thaum cov kua oxidation ua alkaline, hydrogen peroxide decomposes thiab ua rau muaj xwm txheej.
2. Txhim kho cov txheej txheem kho alkali. Thaum muaj qhov txawv txav hauv cov txheej txheem kho alkali, cov pa roj yuav raug coj tawm ntawm kab ke ntawm cov lye. Yog tias qhov sib cais tsis sib cais tag nrho, qhov alkalinity ntawm cov kua dej ua haujlwm tuaj yeem ncav cuag ntau pua zaus ntawm tus nqi ib txwm qhia.
3. nruj me ntsis tswj cov ntsiab lus ntawm cov pa hauv cov pa oxidized. Oxidizing pa gases muaj cov roj combustible. Thaum decomposed thaum lub sij hawm tsim cov txheej txheem, cov pa oxygen concentration nyob rau hauv cov pa sib xyaw pa roj yuav ntau tshaj 15 feem pua, tsim ib tug tawg sib tov. Yog li ntawd, kev tswj xyuas nruj ntawm cov pa roj thiab cov pa oxygen hauv cov pa tawm yog qhov tseem ceeb rau peb. Hauv kev tsim khoom, nitrogen feem ntau yog siv los ua kom cov pa oxidized pov tseg, thiab cov ntsiab lus ntawm cov pa oxygen tswj tau qis dua 10 feem pua kom ntseeg tau tias muaj kev nyab xeeb ntau lawm.
