Tom qab qhov xwm txheej, Cloud Aluminum Co., Ltd. tau pib txoj kev npaj thaum muaj xwm txheej ceev, kev cawm neeg thiab kev pov tseg kom zoo, lub cuab yeej tau ua tiav kev tsim khoom nyob rau hnub tim 22.

2. Kev Txheeb Xyuas Txog Kev Ua Lag Luam:

Cov Ntaub Ntawv Longzhong Kaum Ib Hlis 23: kev lag luam roj av coke hauv tebchaws niaj hnub no feem ntau, tus nqi coke tseem ceeb poob qis, ib feem ntawm tus nqi coke refining txuas ntxiv poob qis. Hauv kev lag luam tseem ceeb, qee lub chaw ua roj ntawm Cnooc qeeb qeeb kev xa khoom, tus nqi coke poob qis 150-200 yuan / ton. Northeast zoo li qub qis sulfur coke xa khoom siab, Jinzhou petrochemical coke tus nqi dav dav poob qis 700 yuan / ton. Northwest kev lag luam ncaj ncees, kev lag luam refinery ib txwm muaj, coke siab ruaj khov. Hauv cov chaw ua roj hauv zos, kev lag luam refinery yog dav dav, kev thov ntawm qhov kawg thov tsis muaj zog, cov khoom lag luam refinery nce ntxiv, tus nqi coke poob qis 30-300 yuan / ton. Beijing bo petrochemical index kho rau cov ntsiab lus sulfur 1.7%.

3. Kev Tshuaj Xyuas Khoom Siv:

Niaj hnub no kev tsim cov roj av coke hauv tebchaws yog 79400 tons, nce ntxiv 100 tons lossis 0.13%. Kev hloov kho cov zis ntawm cov chaw ua roj av.

4. Kev Tshawb Fawb Txog Kev Xav Tau:

Shandong, Hebei thiab lwm qhov chaw tseem txuas ntxiv tswj hwm cov cai tswj hwm hluav taws xob, tsuas yog qee lub tuam txhab tsim hluav taws xob pov tseg hauv thaj av muaj kev cuam tshuam me ntsis, lwm lub tuam txhab feem ntau tswj hwm kev ua haujlwm tsawg; Tag nrho cov xwm txheej tsim khoom ntawm cov tuam txhab hauv sab qab teb sab hnub poob Suav teb yog qhov zoo, thiab thaj chaw txwv hluav taws xob tswj hwm qhov thauj khoom thaum ntxov. Cov khoom tsim tawm ntawm qee lub tuam txhab carbon tshiab xyoo no tso tawm qib siab, thiab cov khoom tsim tawm yuav puv thaum kawg ntawm lub Kaum Ob Hlis, feem ntau rau kev lag luam hauv zos thiab sab qab teb Suav teb, thiab tag nrho qib qis ntawm kev muab khoom lag luam ruaj khov. Kev lag luam hlau carbon tsis zoo, kev xa khoom lag luam graphite electrode thiab carburizer qeeb, kev txhawb nqa zoo rau roj av coke.

5. Kev Kwv Yees Tus Nqi:

Tsis ntev los no, cov khoom siv roj av coke hauv tsev muaj ntau heev, qhov kev thov rau kev ua lag luam yog qhov dav dav, qee lub chaw ua roj coke tus nqi tseem poob qis. Hauv lub sijhawm luv luv, kev ua lag luam roj av coke hauv tsev feem ntau yog teeb tsa, tus nqi coke hauv kev ua lag luam feem ntau ruaj khov, thiab ib feem ntawm tus nqi coke tseem poob qis.
