1. Daim ntawv thov ammonia
Ammonia muaj ntau yam kev siv.
Chiv: Lawv hais tias 80% lossis ntau dua ntawm kev siv ammonia yog kev siv chiv. Pib los ntawm urea, ntau yam chiv uas muaj nitrogen xws li ammonium sulfate, ammonium phosphate, ammonium chloride, ammonium nitrate thiab potassium nitrate yog tsim los ntawm kev siv ammonia ua cov khoom siv raw. Hauv North America, muaj ntau txoj kev siv chiv uas cov kua ammonia raug nchuav ncaj qha rau hauv av.
Cov khoom siv tshuaj lom neeg: Nws yog cov khoom siv raw rau ntau yam khoom siv tshuaj lom neeg uas muaj cov nitrogen atoms, thiab yog ua rau cov resins, cov khoom noj khoom haus ntxiv, cov xim pleev xim, cov nplaum, cov xov hluavtaws, cov roj hmab hluavtaws, cov tshuaj tsw qab, cov tshuaj ntxuav tes, thiab lwm yam.
Denitration: Nws tau teeb tsa rau hauv cov boilers ntawm cov chaw tsim hluav taws xob thermal kom tiv thaiv kev tsim cov nitrogen oxides (NOx) uas ua rau muaj kev phom sij rau ib puag ncig.
Roj rau kev tsim hluav taws xob thermal: Ammonia hlawv nyob ntawm seb muaj xwm txheej li cas, thiab carbon dioxide tsis tsim tawm thaum ammonia raug hlawv. Vim li no, kev tsim kho thev naus laus zis siv ammonia ua roj rau kev tsim hluav taws xob thermal tab tom ua tiav.
tus nqa hluav taws xob (hydrogen): Vim tias kev ua kua ammonia xav tau hluav taws xob tsawg dua li kev ua kua hydrogen, nws tab tom raug kawm ua ib qho ntawm lub zog thiab kev khaws cia hydrogen lossis kev thauj mus los. Tsis tas li ntawd, qee lub tuam txhab tab tom ua haujlwm rau kev tsim cov roj cell uas rho tawm hluav taws xob ncaj qha los ntawm ammonia.
1. Kev siv tshuab ua ammonia
1.1 Cov ntaub ntawv raw rau kev tsim cov ammonia hluavtaws feem ntau yog coke, thee, roj av, roj hnyav, roj sib thiab lwm yam roj, nrog rau cov dej ua pa thiab cua.
1.2 Cov txheej txheem tsim ammonia: Cov khoom siv raw → kev npaj cov roj nyoos → desulfurization → kev hloov pauv ntawm cov pa roj carbon monoxide → decarbonization → kev tshem tawm me me ntawm cov pa roj carbon monoxide thiab cov pa roj carbon dioxide → kev nias → kev tsim cov ammonia → cov khoom ammonia.
3. Daim ntawv thov ntawm compressor hauv kev lag luam ammonia
Huayan Gas khoom siv Co.Ltd tuaj yeem muab cov compressors sib txawv ua tau raws li qhov yuav tsum tau ua hauv kev lag luam ammonia tag nrho.
3.1 Cov roj pub (Nitrogen thiab Hydrogen) compressor
3.2 Rov siv dua lub tshuab cua roj
3.3 Ammonia rov ua kua compressor
3.4 Lub tshuab nqus pa ammonia
