Kev Tshaj Tawm Tshaj Tawm hauv Methylene Chloride: Kev Tsim Kho Tshiab, Kev Cai, thiab Kev Ua Haujlwm Zoo hauv Chemical Sector

Methylene Chloride (MC), ntau yam hnyav hnyav siv dav hauv cov tshuaj, cov nplaum, thiab cov tshuaj aerosol, tab tom hloov pauv tseem ceeb hauv nws cov ntawv thov kev lag luam thiab kev tswj hwm thaj chaw. Kev nce qib tsis ntev los no hauv kev tsim khoom, kev tiv thaiv ib puag ncig kev nyab xeeb, thiab lwm yam kev tshawb fawb hnyav tau hloov kho li cas cov tshuaj no tau pom thiab siv thoob plaws ntiaj teb cov saw hlau.

1. Kev tawg ntawm cov kaw-voj rov ua dua tshiab

Ib txoj hauv kev zoo rau kev rov qab los thiab rov siv cov dichloromethane hauv kev tsim cov txheej txheem tau nce traction hauv 2023. Tsim los ntawm European kev tshawb fawb koom nrog, qhov kaw-loop system siv cov thev naus laus zis adsorption los ntes thiab purify MC vapors emission thaum txheej txheej. Cov kev sim thaum ntxov qhia tau hais tias 92% rov qab tus nqi, txo qis cov khoom siv raw thiab emissions.

Cov thev naus laus zis ua ke nrog AI-tsav kev saib xyuas txhawm rau txhim kho cov kuab tshuaj rov qab siv dua, ua kom muaj kev ua raws li kev txwv nruj ntawm chaw ua haujlwm. Kev lag luam xws li polycarbonate manufacturing thiab hluav taws xob tiv thaiv kev tu yog piloting no system, uas ua raws li lub International Council of Chemical Associations '(ICCA) 2030 ncig kev lag luam lub hom phiaj.

2. Tightening Global Regulations on MC Emissions

Cov kev tswj hwm lub cev tau ua kom muaj kev tshuaj xyuas ntau dua ntawm Methylene Chloride vim nws qhov muaj peev xwm ozone depletion (ODP) thiab kev pheej hmoo ntawm kev ua haujlwm. Thaum lub Cuaj Hlis 2023, European Chemicals Agency (ECHA) tau hais kom hloov kho REACH cov cai, tswj xyuas cov pa hluav taws xob hauv lub sijhawm rau cov chaw siv ntau tshaj 50 tons ntawm MC txhua xyoo. Cov kev cai tseem xav tau kev hloov pauv rau cov ntawv thov tsis tseem ceeb los ntawm Q2 2024.

Tib lub sijhawm, US Environmental Protection Agency (EPA) tau pib tshuaj xyuas MC cov xwm txheej raws li Txoj Cai Tswj Tshuaj Tiv Thaiv Kab Mob (TSCA), nrog rau kev tshawb pom ua ntej qhia txog kev txwv kev ua haujlwm hnyav hauv huab cua - muaj peev xwm txo qis qhov pib ntawm 25 ppm rau 10 ppm. Cov kev ntsuas no tsom los daws qhov kev txhawj xeeb txog kev cuam tshuam rau lub paj hlwb mus sij hawm ntev ntawm cov neeg ua haujlwm hauv kev lag luam.

3. Pharmaceutical Sector txais Greener Alternatives

Kev lag luam kws tshuaj, ib tus neeg siv khoom loj ntawm Methylene Chloridefor tshuaj crystallization thiab extraction, tau nrawm rau kev sim ntawm bio-raws li cov kuab tshuaj. Ib txoj kev tshawb xyuas cov phooj ywg tau luam tawm hauv *Green Chemistry* (Lub Yim Hli 2023) tau qhia txog limonene-derived cov kuab tshuaj raws li kev siv tau MC hloov pauv hauv API (cov khoom siv tshuaj nquag) kev sib txuas, ua tiav cov txiaj ntsig sib piv nrog 80% qis dua cov tshuaj lom neeg.

Thaum kev saws me nyuam tseem nce ntxiv vim muaj teeb meem kev ruaj ntseg, kev tswj hwm kev txhawb siab raws li US Inflation Reduction Act yog pab nyiaj rau cov nroj tsuag pilot nplooj siab rau scaling cov kev xaiv. Cov kws tshuaj ntsuam kwv yees kwv yees li 15-20% txo qis hauv MC thov los ntawm cov tshuaj los ntawm 2027 yog tias tam sim no R&D tiam sis tseem muaj. 

4. Kev nce qib hauv MC Risk Mitigation Technologies

Innovative engineering tswj yog txo qis MC cuam tshuam txog kev phom sij. Ib pab neeg tshawb fawb North American tsis ntev los no tau nthuav tawm nanoparticle-based filtration system uas decomposes residual MC hauv cov dej khib nyiab rau hauv cov khoom tsis muaj tshuaj lom xws li chloride ions thiab carbon dioxide. Cov txheej txheem photocatalytic, qhib los ntawm lub teeb hluav taws xob qis UV, ua tiav 99.6% degradation efficiency thiab tau muab tso rau hauv cov chaw kho dej khib nyiab.

Tsis tas li ntawd, cov cuab yeej tiv thaiv tus kheej tiam tom ntej (PPE) uas muaj cov cuab yeej ua pa graphene tau pom 98% kev ua tau zoo hauv kev thaiv cov MC vapors thaum lub sijhawm ua haujlwm siab xws li pleev xim. Cov kev txhim kho no ua ke nrog OSHA cov txheej txheem kho tshiab uas hais txog kev tswj hwm kev cuam tshuam rau MC cov neeg ua haujlwm. 

5. Sustainability-Driven Market Shifts

Txawm hais tias nws lub luag haujlwm tseem ceeb, Methylene Chloride ntsib kev nyuaj siab los ntawm ESG (ib puag ncig, kev sib raug zoo, kev tswj hwm) peev txheej txheem. Ib daim ntawv ntsuam xyuas xyoo 2023 los ntawm cov kws tshuaj ntsuam xyuas kev lag luam tshuaj lom neeg tau tshaj tawm tias 68% ntawm cov chaw tsim khoom lag luam hauv qab tam sim no tseem ceeb rau cov neeg muag khoom nrog kev txheeb xyuas MC cov phiaj xwm txo qis. Cov qauv no yog txhawb kev tsim kho tshiab hauv cov kuab tshuaj rov qab los thiab cov txheej txheem bio-hybrid ntau lawm.

Qhov tseem ceeb, ib txoj haujlwm tsav tsheb nyob rau sab hnub tuaj Asia tau ua tiav MC siv methane chlorination powered los ntawm lub zog tauj dua tshiab, txiav cov pa roj carbon hneev taw ntawm kev tsim khoom los ntawm 40%. Txawm hais tias muaj kev sib tw scalability tseem nyob, cov kev pib no qhia txog cov tshuaj lom neeg cov kev pivot mus rau decarbonized hnyav ecosystems.

Xaus: Sib npaug Utility thiab lub luag haujlwm

Raws li Methylene Chloride tseem yog qhov tseem ceeb rau cov ntawv thov tseem ceeb, kev lag luam tsom mus rau kev tsim kho tshiab kom ruaj khov thiab kev tswj hwm kev ua raws cai tau nce ntxiv. Kev sib cuam tshuam ntawm cov txheej txheem rov qab los, kev nyab xeeb dua, thiab cov cai hloov pauv yuav txhais tau MC lub luag haujlwm hauv lub neej yav tom ntej uas tsis tshua muaj carbon. Cov neeg muaj feem cuam tshuam thoob plaws cov txiaj ntsig yuav tsum tam sim no mus rau theem kev hloov pauv no - qhov chaw ua haujlwm tau zoo thiab kev saib xyuas ib puag ncig - kom ruaj ntseg mus ntev.
