Yellow phosphorus thiab phosphoric acid sawv ua ke
Yunnan-guizhou daj phosphorus nqi nce. Cov ntaub ntawv qhia tias qhov kev thov ntawm 34500 yuan / ton thaum pib ntawm lub lim tiam tau nce mus rau 60,000 yuan / ton thaum kawg ntawm lub lim tiam, nce 73.91% hauv lub lis piam, 285.85% xyoo-rau-xyoo. - xyoo.
Yunnan Development thiab Reform Commission tau tshaj tawm tsab ntawv ceeb toom ntawm Yunnan Energy Conservation Leading Group Office ntawm Resolutely Ua ib tug zoo txoj hauj lwm nyob rau hauv zog Consumption Double Control, uas tau hais ntxiv dag zog rau kev tswj ntawm daj phosphorus kev lag luam kom ntseeg tau tias qhov nruab nrab txhua hli tso zis ntawm daj phosphorus ntau lawm kab txij lub Cuaj Hli. Txog rau lub Kaum Ob Hlis 2021 yuav tsum tsis pub tshaj 10% ntawm cov zis ntawm lub Yim Hli 2021 (piv txwv li, txo cov zis los ntawm 90%).
Muaj kev cuam tshuam los ntawm cov xov xwm, kev tsim cov phosphorus daj yuav tsum txo qis, cov nqes qis pib yuav daj phosphorus, nrog rau qhov ua rau muaj qhov hnyav ntawm cov phosphorus qhov chaw nro, daj phosphorus cov nqi txuas ntxiv nce ntxiv.Yellow phosphorus kev lag luam nqi nce, daj phosphorus lag luam txwv voltage load, muaj peev xwm txo, qhov chaw nro intensifies.Tus nqi ntawm upstream phosphate ore thiab coke nce, thiab tus nqi ntawm downstream phosphoric acid nce txhua txoj kev.Lub downstream pib yuav daj phosphorus ntawm tus nqi siab, thiab kev lees txais cov xim daj phosphorus siab.Zuag qhia tag nrho, kev ua lag luam muaj kev ntseeg siab zoo thiab muaj zog txhawb nqa los ntawm cov dej ntws thiab cov dej ntws qis.Nws xav tias nyob rau lub sijhawm luv luv, kev ua lag luam daj phosphorus nyuaj rau kev cia siab.
Yunnan yog ib lub xeev muaj peev txheej nplua nuj nyob hauv Suav teb, thiab kev lag luam tshuaj lom neeg tau dhau los ua ib qho kev lag luam ntawm yunnan kev lag luam kev lag luam, nrog cov phosphorus daj muaj peev xwm suav txog ntau dua 40% thiab silicon muaj peev xwm 20% ntawm lub teb chaws. Thaum kawg ntawm xyoo 2020, muaj 346 lub tuam txhab tshuaj lom neeg tshaj li qhov loj me hauv lub xeev.
Raws li Daim Ntawv Ceeb Toom Txog Kev Tswj Xyuas Kev Siv Hluav Taws Xob tau tshaj tawm los ntawm Yunnan Provincial Tus Thawj Coj Lub Chaw Haujlwm Saib Xyuas Kev Tiv Thaiv Hluav Taws Xob, qhov nruab nrab txhua hli cov khoom tsim tawm ntawm cov kab hluav taws xob daj phosphorus txij lub Cuaj Hli mus txog Lub Kaum Ob Hlis yuav tsum tsis pub tshaj 10% ntawm cov zis ntawm Lub Yim Hli (xws li, 90% txo. ). Qhov nruab nrab txhua hli cov khoom lag luam silicon yuav tsum tsis pub tshaj 10% ntawm cov zis ntawm lub Yim Hli (piv txwv li, 90% txo); Raws li kev tsim cov chiv, tshuaj raw khoom tsim, thee ua, ferroalloy refining thiab li ntawm plaub industries, lub ntxiv tus nqi ntawm lub zog noj ib kaum txhiab yuan siab tshaj qhov kev lag luam nruab nrab kev siv hluav taws xob ntawm cov lag luam hauv cov tuam txhab tseem ceeb txais kev tswj hwm, suav nrog kev siv hluav taws xob ntau dua li qhov nruab nrab 1-2 zaug txwv kev tsim khoom 50%, 2 npaug siab dua qhov nruab nrab ntawm kev siv hluav taws xob ntawm cov lag luam txwv. tso zis los ntawm 90%.
Yunnan xeev yuav tsum tau tsom mus rau petrochemical, tshuaj, thee tshuaj, hlau thiab hlau, coking, tsev cov ntaub ntawv, non-ferrous industries, tsim ib daim ntawv teev kev tswj system ntawm "ob siab" tej yaam num, tshem tawm ib tug xov tooj ntawm inefficient thiab rov qab muaj peev xwm ntau lawm, nquag coj kev lag luam los txhawb kev tsim ntsuab thiab cov pa roj carbon tsawg, txhawb kev hloov pauv kev lag luam thiab kev txhim kho, thiab txhim kho qhov zoo thiab kev ua haujlwm ntawm kev tsim kho.
Jiangsu: dej qab zib kev lag luam tus nqi yuav poob 20%.
Jiangsu, hu ua "Su Daqiang", tam sim no muaj 14 chemical industrial parks thiab 15 chemical concentration area.Thaum kawg ntawm lub Kaum Ob Hlis 2020, muaj ntau tshaj 2,000 chemical enterprises nyob rau hauv Jiangsu Province.
Hauv lub xeev Jiangsu, kev tswj ob npaug ntawm kev siv hluav taws xob yog nyob rau hauv tus txheej txheem ntawm kev saib xyuas ntxiv.Xyoo 2021, kev saib xyuas tshwj xeeb txuag hluav taws xob yuav raug tsim tawm rau cov lag luam nrog txhua xyoo kev siv hluav taws xob ntau dua 50,000 tons.Cov kev tswj xyuas tshwj xeeb ntawm kev txuag hluav taws xob muaj xws li 323 lub lag luam nrog txhua xyoo kev siv hluav taws xob ntau dua 50,000 tons ntawm tus qauv. thee, 29 txoj haujlwm nrog kev siv hluav taws xob ntau dua 50,000 tons ntawm cov qauv thee, thiab cov haujlwm nrog kev siv hluav taws xob ntau dua 5,000 tons ntawm cov qauv thee uas tau muab tso rau hauv kev ua haujlwm txij li xyoo 2020 (cov npe ua haujlwm yuav muab cais tawm). petrochemical, tshuaj, thee chemical, coking, hlau thiab hlau, cov ntaub ntawv hauv tsev, tsis yog ferrous, thee fais fab, textile, ntawv ua, cawv thiab lwm yam lag luam.
Kev cuam tshuam los ntawm qhov no, qee lub tuam txhab dej qab zib hauv Jiangsu tau npaj los txo cov khoom lag luam hauv lub Cuaj Hli, thiab kev khiav hauj lwm tus nqi poob los ntawm 20%. Jiangsu dej qab zib muaj peev xwm suav txog 17.4% ntawm tag nrho cov peev txheej tsim khoom hauv tsev, ua rau qhov kev poob qis ntawm cov nqi dej qab zib txuas ntxiv mus. muaj zog.Lub quarter thib ob thiab peb lub hlis twg yog lub caij nyoog txij nkawm ntawm cov dej qab zib, thiab cov khoom siv tau pom tseeb txo qis. Ntxiv rau, cov khoom siv tsis tu ncua thiab kev txwv tsis pub muaj zog, nrog rau cov xwm txheej ib puag ncig, tau txo cov khoom lag luam zoo heev.
Inner Mongolia: tsis muaj kev pom zoo ntxiv ntawm PVC, methanol, ethylene glycol thiab lwm yam haujlwm tshiab
Kev lag luam tshuaj lom neeg yog lub hauv paus kev lag luam thiab kev lag luam ib txwm muaj txiaj ntsig kev lag luam ntawm Inner Mongolia Autonomous Region, thiab tau tsim ntau yam kev lag luam xws li coking, chlor-alkali, niaj hnub thee chemical kev lag luam, tshuaj lom neeg kev lag luam thiab lwm yam.Qhov tso zis ntawm methanol, polyvinyl chloride, polyolefin resin thiab lwm yam khoom tseem ceeb nyob rau hauv Tuam Tshoj.Tam sim no, Inner Mongolia chemical kev lag luam muaj 58 chaw ua si (chaw chaw) thiab ntau pua lub tuam txhab tshuaj.Qhov feem ntawm lub zog thiab raw khoom kev lag luam thiab siab zog noj thiab siab emission kev lag luam. nyob rau hauv Inner Mongolia Autonomous Region yog loj, tshwj xeeb tshaj yog cov thee chemical kev lag luam, tag nrho cov kev siv zog thiab kev siv zog ntawm ib chav tsev tso zis nqi yog nyob rau theem siab.
Raws li "Ntau yam kev ntsuas los xyuas kom meej qhov ua tiav ntawm" 14th Tsib-xyoo txoj kev npaj "zog noj ob lub hom phiaj los ntawm Inner Mongolia Development thiab Reform Commission, pib los ntawm 2021, coke (xiav carbon), calcium carbide, PVC, hluavtaws ammonia (urea), methanol, ethylene glycol, caustic soda, dej qab zib, ammonium phosphate, daj phosphorus ... Tshiab muaj peev xwm tej yaam num xws li polysilicon thiab monocrystalline silicon tsis downstream hloov dua siab tshiab yuav tsis pom zoo. Los ntawm kev tswj scale, suppressing ntau lawm muaj peev xwm, nws yog inevitable maj mam txo cov khoom muaj feem xyuam.
