Cov roj tseem ceeb ua tau: methane, carbon monoxide, hydrogen, liquefied gas.
1. Biogas pas dej ua ke
Kev tsim kho ntawm biogas digesters nyob rau hauv ntau qhov chaw tsis tsuas yog txhim kho kev huv ntawm cov neeg nyob deb nroog, tab sis kuj txo lub nra ntawm cov neeg ua liaj ua teb, tiv thaiv ecology, thiab feem ntau txais tos los ntawm cov neeg ua liaj ua teb. Txawm li cas los xij, PH tus nqi ntawm cov ntaub ntawv fermentation hauv biogas digesters yuav tsum yog 6.8 ~ 7.5, thiab cov ntsiab lus ntawm biogas tsim kuj yuav tsum tau kuaj.
Kev tshawb pom tseem ceeb: methane, carbon dioxide, PH nqi.
2. Cua zoo tswj
Nrog rau kev txhim kho kev nyab xeeb thiab kev paub txog kev noj qab haus huv, tib neeg tau nrawm dua los tswj cov huab cua zoo ntawm cov chaw nres tsheb hauv av, kev tsheb ciav hlau thiab lwm qhov chaw lossis qhov tsis siv neeg qhov cua ntawm lub hauv paus cua txias. Hauv kev ua haujlwm ntawm cov kav dej hauv nroog, kev kho dej phwj tuaj, hauv nroog cov yeeb nkab network, thiab lwm yam, tsoomfwv hauv nroog yuav tsum siv cov khoom siv roj los ntes cov tshuaj chlorine, hydrogen sulfide thiab lwm cov pa roj hauv kev kho dej thiab cov dej phwj tuaj kho.
3. Hlau smelting
Kev lag luam hlau thiab hlau yog ib qho tseem ceeb ntawm cov khoom siv raw hauv lub teb chaws, tab sis cov khoom lag luam "gas" ntau heev (piv txwv li: coke cub gas, blast furnace gas, converter gas) yuav raug tsim tawm hauv smelting thiab ntau lawm. txheej txheem. Combustible gas), kev tiv thaiv tsis zoo, ua rau muaj roj lom lossis tawg tawg. Yog li ntawd, nws yog ib qho tseem ceeb heev rau kev lag luam metallurgical los txhim kho cov khoom siv hluav taws xob txhawm rau txhawm rau txheeb xyuas cov pa roj.
Cov pa roj carbon monoxide (CO), methane (CH4), hydrogen (H2), hydrogen sulfide (H2S), benzene (C6H6), ammonia (NH3), carbon disulfide (CS2), oxygen (O2), carbon Dioxide (CO2), nitrogen (N2), naphthalene (C10H8), phenol, thiab lwm yam.
Plaub, kev lag luam fais fab
Kev lag luam hluav taws xob muaj ntau qhov chaw thiab muaj qhov chaw ua lag luam dav. Nws tuaj yeem ntes cov roj sulfur hexafluoride uas tsim los ntawm cov chaw nres tsheb fais fab.
Lub ntsiab gases tsim yog: ammonia, chlorine, hydrogen sulfide, sulfur hexafluoride, oxygen, combustible gas, hydrogen, carbon monoxide, sulfur dioxide, nitrogen oxides, thiab lwm yam.
5. Polysilicon kev lag luam
Cov txheej txheem ntau lawm ntawm polysilicon yog tsim los ntawm high-purity quartz (txo los ntawm high-temperature coke) - industrial silicon (pickling) - silicon hmoov (ntxiv HCL - SiHCL3 (los ntawm crude distillation thiab rectification) - high-purity SiHCL3 (nrog hydrogen cov tshuaj tiv thaiv CVD) txheej txheem) - high-purity polysilicon.
6. Kev lag luam thee
Kev lag luam coking, thee gasification, hluavtaws ammonia, thee-based methanol, thee-based synthetic oil, thiab thee chemical co-production txhua tus muaj kev xav tau ntau rau lub tswb nrov, tshwj xeeb tshaj yog rau sulfur dioxide, hydrogen sulfide, carbon monoxide, chlorine, ammonia thiab lwm yam. gas detectors. Loj heev.
Cov roj tseem ceeb ua tau: carbon monoxide, hydrogen sulfide, methane, sulfur dioxide, chlorine, ammonia.
Tsis tas li ntawd, kev lag luam chlor-alkali, tshuaj lom neeg zoo, kev lag luam txhuas, tsev cog khoom ua liaj ua teb, khoom noj khoom haus txias cia, hauv nroog tsheb tso pa tawm thiab lwm qhov chaw txhua qhov yuav tsum tau kuaj cov pa roj, thiab txhua yam yuav tsum tau teeb tsa lub tswb ntsuas roj.
