Txij thaum kawg ntawm lub Tsib Hlis hauv Is Nrias teb, mus rau qhov qhib ntawm kev twv hauv ob hnub dhau los, kev ua lag luam urea hauv tsev zoo li lub roller coaster, ib nrab lub hlis tau ntsib nthwv dej ntawm roller coaster zoo li kev ua lag luam. Nrog rau qhov qhib maj mam ntawm tus nqi luam ntawv, kev ua lag luam hauv tsev tau xaus rau lub sijhawm tam sim no. Rov qab mus rau cov hauv paus, kev ua lag luam nthwv dej me me yuav txuas ntxiv rov ua dua, tab sis qhov sib txawv tag nrho yuav khiav qis dua.

Cov nyhuv ntawm lub cim yog xob laim loj tab sis nag me ntsis

Lub cim luam ntawv, lub sijhawm tsuas yog nyob rau hauv lub sijhawm rhiab heev, lub teb chaws tau ntsib ntev li ob lub hlis ntawm kev lag luam poob, kev lag luam thiab kev ua liaj ua teb thov thiab tsuas yog superimposed ua ke, yog li lub cim luam ntawv no fuse, ignited lub nthwv dej ntawm kev rov qab sai hauv kev lag luam hauv teb chaws. Txawm li cas los xij, qhov tseeb, los ntawm qhov pom ntawm tus nqi luam ntawv, qhov qis tshaj plaws CFR284.9 US dollars / ton ntawm ntug dej hiav txwv sab hnub tuaj, kev suav ntawm cov cheeb tsam hauv tsev yog tsawg dua 1,800 yuan / ton, thiab tam sim no qhov sib txawv ntawm tus nqi qhov chaw tsawg kawg yog 200 yuan / ton; Tom qab ntawd hnub xa khoom kawg yog Lub Xya Hli 17, thaum lub caij ntuj sov chiv lag luam hauv thaj chaw tseem ceeb tsis tau xaus tag nrho; Thaum kawg, qhov ntim ntawm 800,000 tons hauv Suav teb thiab Arab lub teb chaws, kev muab khoom ntawm 2.52 lab tons, lub ntiaj teb kuj muaj txaus rau kev muab khoom. Yog li ntawd, nyob rau hauv cov nqe lus ntawm ntim thiab lub sijhawm nqi, qib ntawm kev koom tes hauv tsev yog tsawg, thiab rau lub luag haujlwm tseem ceeb ntawm lub teb chaws, nws kuj tseem yuav muaj kev cuam tshuam me me, ces kev ua lag luam yuav tsum rov qab mus rau qhov tseem ceeb.

Kev thov hauv tsev maj mam ua rau cov kev txwv ntawm kev txhawb nqa kev ua liaj ua teb tsis muaj zog

Vim tias qhov kev thov siab tshaj plaws rau cov chiv nitrogen siab tsis muaj zog, kev tsim kho ntawm cov lag luam tau poob qis, kev tsim kho ib ntus ntawm cov lag luam chiv sib xyaw tau qhia txog kev poob qis, thiab qhov kev thov rau cov khoom siv raw urea kuj tseem yuav txo qis heev, thiab nws tau kwv yees ua ntej tias yuav muaj kev nce me ntsis hauv lub Xya Hli. Hauv kev lag luam phaj, vim yog qhov kub thiab txias thiab huab cua los nag hauv lub caij ntuj sov, qhov kev thov rau urea kuj tseem yuav poob qis, yog li qhov kev thov tseem ceeb yuav raug tsom mus rau kev ua lag luam ua liaj ua teb. Tom qab sau qoob loo hauv thaj chaw tseem ceeb, nws ib ntus nkag mus rau lub sijhawm ua liaj ua teb sib txawv, thiab tom qab kaum lossis nees nkaum hnub, nrog rau lub voj voog loj hlob ntawm cov qoob loo, yuav muaj qhov kev thov kom zoo hauv qee thaj chaw, thiab tom qab ntawd yuav muaj qhov kev thov ua liaj ua teb luv luv ua ke nrog huab cua. Txawm li cas los xij, tom qab Lub Xya Hli, qhov kev thov ua liaj ua teb kuj tseem ceeb hauv ob lub caij hauv ib xyoos, yog li muaj kev txhawb nqa, tab sis nws tsawg heev, thiab kev ruaj khov yog txwv.

Kev muab khoom ntawm cov khoom muag ntxiv rau cov pib yog txaus.

Kev ua lag luam ntawm lub voj voog no kuj tau ua rau muaj kev poob qis ntawm cov khoom lag luam hauv tuam txhab. Txij li lub lim tiam no, cov ntaub ntawv tshiab tshaj plaws qhia tau tias cov khoom muag ntawm cov tuam txhab urea yog li ntawm 620,000 tons, piv rau tus nqi siab tshaj plaws ntawm 1.16 lab tons, txo qis ntawm 540,000 tons, poob qis ib nrab. Feem ntau ntawm cov khoom no yuav raug zom los ntawm kev lag luam thiab kev ua liaj ua teb, tab sis kuj muaj me ntsis ntawm nws tau ntws mus rau hauv kev ua lag luam chiv hauv thaj chaw tseem ceeb, feem ntau yog vim muaj kev poob qis ntev hauv kev ua lag luam yav dhau los, ua rau ib feem ntawm qhov kev thov khaws cia qeeb. Tom qab ntawd raws li cov khoom muag no, ua ke nrog kev tsim khoom xyoo no thiab kev nce ntxiv ib ntus hauv kev xa khoom, rau tib lub sijhawm, cov khoom muag tau suav rau hauv qhov ntau thiab tsawg theoretical.

Thiab qhov kev poob qis tom ntej hauv cov khoom muag yuav qeeb qeeb, feem ntau yog vim kev lag luam pib txaus hauv tib lub sijhawm. Raws li cov ntaub ntawv Longzhong, kev lag luam urea txhua hnub tsim tawm ntawm 174,800 tons rau lub Rau Hli 14, nce ntawm 0.70 lab tons dhau tib lub sijhawm. Nyob nruab nrab ntawm lub hlis, Daqing Petrochemical thiab Aowei muaj cov phiaj xwm kho chaw nres tsheb, thiab nyob rau hauv ib nrab ntawm lub hlis, Yangmei Plain, Henan Xinlianxin, Mingshengda, Jinxin thiab lwm cov nroj tsuag yuav tsum muaj cov phiaj xwm kho, thiab cov zis txhua hnub tuaj yeem txo qis dua 170,000 tons hauv ib nrab xyoo tom ntej, tab sis txawm li ntawd los, cov zis txhua hnub tsawg dua 160,000 tons. Ua ntej thiab tom qab Lub Xya Hli, muaj ob pawg ntawm cov peev xwm tsim khoom tshiab yuav raug tso tawm, thiab cov khoom txaus yog qhov siab tshaj plaws ntawm kev ua lag luam.

Hauv kev xaus lus, cov hauv paus ntawm kev siv urea hauv tsev luv luv tsis muaj zog tag nrho, txawm tias lub lauj kaub rov zoo dua tsis ntev los no, tab sis kuj tsis tuaj yeem thaiv qhov kev poob qis, tsuas yog yuav tsum tiv thaiv tus nqi poob qis. Raws li kev ua lag luam hnav khaub ncaws rau lub caij ntuj sov, qhov ntau ntawm kev thov kev lag luam thiab kev poob qis hauv kev tsim kho, txawm tias me me ntawm kev xa khoom tawm, thiab lwm yam, yog tias ntau dua ob sab tshwm sim, tseem tuaj yeem muaj cov lag luam me me hauv cheeb tsam, yog li qhov tam sim no ua yog tos kom muaj kev hloov pauv tseem ceeb hauv cov txheej txheem txo nqi.
