Thawj zaug nyob rau hauv lub teb chaws nyob rau hauv-situ Gasification ntawm Coal Seams Ntau txhiab meters hauv av tau ua tiav

Qhov kev ntsuam xyuas underground thee gasification (UCG) ntawm thaj av autonomous qhov kev tshawb fawb thiab thev naus laus zis loj los ntawm Xinjiang Yaxin Coalbed Methane Investment and Development (Group) Co., Ltd. tau ua tiav ignited ib zaug, thiab tib lub sijhawm nws ua tiav "dual. gas co-exploitation" ntawm qhov nyuaj-rau-extract thee peev txheej. Qhov project Lub tshuab yog thawj zaug hauv lub ntiaj teb.

Wei Bo, tus lwm thawj saib xyuas ntawm Yaxin Coalbed Methane Group, tau hais tias "dual gas co-exploitation" thev naus laus zis tuaj yeem siv tsis tau tsuas yog siv cov pa roj carbon monoxide hauv coal seams xwb, tab sis kuj tau txais cov roj thee tib lub sijhawm, uas txhim kho kev siv tau zoo ntawm thee peev txheej.
Nws tau tshaj tawm tias qhov kev xeem UCG yog ib qho kev nyuaj uas yuav tsum tau hais txog hauv kev tshawb fawb thiab thev naus laus zis tseem ceeb ntawm Autonomous Region Science thiab Technology Department, "Technology for Efficient Development of Coalbed Methane Resources in Xinjiang's Difficult to Mine Coals." Txoj haujlwm yuav raug tsim tawm thaum lub Plaub Hlis 2023 thiab tshwj xeeb tshaj yog mob siab rau kev kov yeej cov thev naus laus zis tseem ceeb thiab nyuaj rau kev huv thiab siv tau zoo ntawm cov thee (hauv av coal gasification) thiab kev txhim kho thee txaj methane.
Tom qab kev tshawb fawb thiab kev xyaum ua haujlwm ntev ntev, pab pawg tshawb fawb tshawb fawb tau ua tiav los ntawm cov kev txwv ntawm kev siv hluav taws xob siv hluav taws xob thiab ua tiav ib zaug ua tiav qhov hluav taws kub, tso lub hauv paus ruaj khov rau kev lag luam loj ua qauv qhia ntawm underground thee gasification.
Wei Bo tau hais tias qhov project kuj tau ua tiav nyob rau hauv-situ gasification ntawm thee seams ntev tshaj li ib mais, uas yog thawj zaug nyob rau hauv Suav teb uas qhov kev siv technology tshiab no tau ua tiav. Kev tsim kho ntawm super-loj tsis zoo underground gasifier kuj yog thawj zaug hauv Suav teb. Cov kev ua tiav tshiab no qhia tau hais tias Yaxin Coalbed Methane Group lub zog zoo hauv kev tshawb fawb thiab kev tsim kho thev naus laus zis.
Qhov nruab nrab calorific tus nqi ntawm cov pa roj hauv qhov ntsuas UCG no tshaj 2,500 kcal ib cubic meter, nrog rau siab tshaj 4, 000 kcal ib cubic meter. Cov txiaj ntsig tau mus txog qib ua hauv tsev thiab txawv teb chaws. Qhov kev nce hauv tus nqi calorific no yuav muab kev txhawb zog ntxiv rau kev siv lub zog huv.
"Kev ua tiav ib zaug ntawm kev siv hluav taws xob hluav taws xob hauv av thiab kev siv hluav taws xob ob lub roj sib xyaw ua ke" yog ib qho tseem ceeb hauv kuv lub teb chaws lub zog thiab lub ntsiab lus tseem ceeb hauv lub ntiaj teb kev hloov hluav taws xob huv. lub tuam txhab, tseem yuav muaj kev cuam tshuam zoo rau lub teb chaws kev ruaj ntseg hluav taws xob thiab kev tiv thaiv ib puag ncig. " Wei Bo tau hais tias yav tom ntej, Yaxin Coalbed Methane Group yuav nquag txhawb kev tsim kho kev lag luam ntawm underground coal seam gasification.
