Keeb kwm ntawm qhov project
Petrochemical yog kev ua lag luam uas tsim cov khoom siv roj av thiab petrochemicals siv cov roj thiab cov nkev li cov khoom siv raw. Cov roj nyoos uas tsim los ntawm cov txheej txheem refining yog chemically tiav los tsim cov khoom petrochemical. Txhawm rau tsim cov khoom siv tshuaj lom neeg tseem ceeb ethylene, propylene, butadiene, benzene, toluene, thiab xylene, nws yog ib qho tsim nyog yuav tsum tau ua ntej tawg cov roj thiab roj (xws li propane, roj av, diesel, thiab lwm yam). Qhov thib ob theem entails tsim ntau yam khoom siv hluavtaws los ntawm cov ntaub ntawv raw tshuaj lom neeg nrog rau ntau tshaj 200 ntau hom organic chemical raw khoom.
Kev lag luam petrochemical, nrog rau kev lag luam petrochemical-raws li kev lag luam xws li tshuaj chiv, txiv neej ua fibers, hluavtaws resins thiab yas, xim, cov khoom siv tu, cov txiv neej ua fiber ntau textiles, knitting, thiab cov khoom siv roj hmab, yog txhua yam txuas nrog tib neeg kev nkag mus. zaub mov, khaub ncaws, thiab tsev nyob. Petrochemical sector muab ib ncig ntawm 70 feem pua ntawm cov khoom siv kho vajtse siv hauv cov khoom lag luam precision, suav nrog cov khoom, casings, log tsheb, tshuaj, thiab lwm yam.
Keeb kwm ntawm qhov project
Petrochemical hais txog kev ua lag luam uas siv cov roj thiab cov nkev ua cov khoom siv raw los tsim cov khoom siv roj av thiab cov khoom siv petrochemical. Petrochemical cov khoom tau txais los ntawm kev ua tshuaj lom neeg ntawm cov roj nyoos los ntawm cov txheej txheem refining. Thawj kauj ruam hauv kev tsim cov khoom lag luam petrochemical yog txhawm rau txhawm rau cov roj thiab roj (xws li propane, roj av, diesel, thiab lwm yam) los tsim cov khoom siv tshuaj lom neeg yooj yim uas sawv cev los ntawm ethylene, propylene, butadiene, benzene, toluene, thiab xylene. Cov kauj ruam thib ob yog los tsim ntau tshaj 200 hom organic chemical raw khoom thiab ntau yam khoom siv hluavtaws los ntawm cov khoom siv tshuaj lom neeg yooj yim.
Ntxiv nrog rau kev lag luam petrochemical, petrochemical-dependent industries xws li tshuaj chiv, txiv neej ua fibers, hluavtaws resins thiab yas, xim, cov khoom siv tu, cov txiv neej ua fiber ntau textiles, knitting, thiab cov khoom siv roj hmab kuj muaj feem xyuam nrog tib neeg cov zaub mov, khaub ncaws, vaj tse, kab muaj kev sib raug zoo. Kwv yees li 70 feem pua ntawm cov khoom siv kho vajtse ntawm cov khoom lag luam precision, xws li qhov chaw, casings, log tsheb, tshuaj, thiab lwm yam, los ntawm kev lag luam petrochemical.
roj txaus ntshai
Cov ntaub ntawv koom nrog hauv petrochemical ntau lawm yog qhov txaus ntshai, thiab qhov tshwm sim ntawm hluav taws kub, tawg, kev tuag loj thiab raug mob raug mob yog siab. Petrochemical ntau lawm, los ntawm raw cov ntaub ntawv mus rau cov khoom, xws li semi-tiav khoom, intermediates, ntau yam kuab tshuaj, additives, catalysts, reagents, thiab lwm yam nyob rau hauv tus txheej txheem, feem ntau yog flammable thiab combustible tshuaj, raws li zoo raws li cov khoom tawg xws li roj crude. , natural gas, gasoline, kua hydrocarbons, ethylene, propylene, thiab lwm yam. Feem ntau ntawm lawv muaj nyob rau hauv lub xeev ntawm cov pa roj thiab kua, uas yog ib qho yooj yim rau to thiab volatilize. Muaj ntau cov ntaub ntawv uas muaj tshuaj lom thiab muaj tshuaj lom heev, xws li benzene, toluene, sodium cyanide, hydrogen sulfide, chlorine, thiab lwm yam, uas yog pov tseg tsis zoo los yog xau. , uas tuaj yeem yooj yim ua rau raug mob. Nyob rau hauv cov txheej txheem petrochemical ntau lawm, ntau yam corrosive acids thiab alkalis kuj tseem siv thiab tsim, xws li sulfuric acid, hydrochloric acid, caustic soda, thiab lwm yam., muaj peev xwm ntawm cov khoom siv thiab cov teeb meem corrosion yog siab; qee cov ntaub ntawv kuj muaj cov yam ntxwv ntawm kev sib xyaw ua ke thiab kev sib tsoo hnyav. Xws li hlau organic catalysts, ethylene, thiab lwm yam tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntau lawm, cov txheej txheem kev khiav hauj lwm yog hnyav, nrog rau kev kub siab, cryogenic kub, siab siab, thiab lub tshuab nqus tsev. Ntau qhov cua sov kub tau mus txog lossis dhau ntawm qhov tshwm sim tshwm sim ntawm cov khoom siv. Thaum ua haujlwm tsis raug lossis cov khoom siv tsis zoo, hluav taws kub thiab tawg yuav tshwm sim heev. Tsis tas li ntawd, kom deb li deb raws li cov txheej txheem thev naus laus zis tam sim no, nyob rau hauv ntau cov txheej txheem tsim khoom, cov ntaub ntawv yuav tsum tau ua kom sov nrog cov nplaim taws qhib; Tsis tas li ntawd, kev tu cov cuab yeej siv niaj hnub yuav tsum tau ua kom sov tsis tu ncua. Qhov no suav nrog qhov tsis sib xws tseem ceeb, uas yog, kev ntshai ntawm hluav taws, tab sis kuj yog kev siv hluav taws, ua ke nrog cov khoom loj ntawm cov khoom tawg thiab tawg hauv ntau lub lag luam thiab kev teeb tsa, thaum lawv tsis ua haujlwm zoo, kev sib tsoo yuav tshwm sim, thiab qhov tshwm sim yog unimaginable. Cov xwm txheej tau ua pov thawj tag nrho cov ntsiab lus no. Tsis tas li ntawd, nyob rau hauv ib puag ncig kev lag luam thiab kev tsim kho, muaj qee yam teeb meem, xws li kev lag luam suab nrov, kub kub, plua plav, rays thiab lwm yam. Cov tshuaj lom thiab teeb meem no yuav ua rau muaj kev phom sij txaus ntshai, thiab tseem yuav nce ntxiv nyob rau lub sijhawm, txawm tias nyob rau hauv qis concentration (dose) cov xwm txheej, vim lawv cov kev sib xyaw ua ke, lawv yuav cuam tshuam rau kev noj qab haus huv ntawm cov neeg ua haujlwm thiab ua rau ntau yam kab mob ua haujlwm.
Cov txheej txheem txheej txheem
Qhov kev hem thawj tuag nyob rau hauv kev lag luam no yog nyob rau hauv cov pa taws thiab combustion ntawm cov roj tawg, uas yog ib txwm nrog rau tag nrho cov txheej txheem ntawm kev tsim khoom thiab kev ua haujlwm. Siv ntau lub tshuab ntsuas roj los ua lub sijhawm thiab saib xyuas ntawm cov chaw lag luam thiab chaw ua si, teeb tsa cov khoom siv hluav taws xob thiab tshuaj lom neeg hauv cov pa xau zais qhov chaw txaus ntshai, cov neeg ua haujlwm hauv chaw ua haujlwm thiab chaw cia roj, koom tes nrog lub tswb tswj cov txee, kev txheeb xyuas cov ntaub ntawv keeb kwm yav dhau, thiab cov chaw ua haujlwm cov ntaub ntawv, uas tuaj yeem paub zoo txog kev saib xyuas, tso saib thiab ceeb toom ntxov hauv cheeb tsam saib xyuas, yog li txo cov hluav taws kub thiab tawg, zam kev raug mob, thiab ua kom muaj kev nyab xeeb ntawm cov khoom lag luam thiab cov chaw ua si.
