Kugonjetsa Kuboola Kwambiri kwa Geothermal: Momwe Odulira a PDC Omwe Anasochera Amasinthira Kugwira Ntchito Bwino

Pamene kukula kwa mphamvu ya geothermal mu 2025 kukukulirakulira, ukadaulo wa "wochotsedwa ndi leached (cobalt)" ukutsogolera pa kafukufuku wamakampani, chifukwa cha kufunikira kwa zida zobowola zomwe zimatentha kwambiri komanso zosawonongeka. Wuhan Ninestones Superabrasives Co., Ltd., kampani yodulira ya PDC, ikusintha mawonekedwe a geothermal pogwiritsa ntchito ukadaulo wapamwamba wochotsedwa ndi leached, ndiDzino la MR1613A6 Diamond Ridgeimayimira ngati chinthu chosintha kwambiri.

Mapulojekiti ozama a geothermal monga EGS ndi miyala youma kwambiri amafuna zida zopirira kutentha kwa 150–200°C pansi pa dzenje. Odulira achikhalidwe a PDC amagwiritsa ntchito cobalt ngati chothandizira, chomwe chimathandizira kuti diamondi graphitization ichitike mwachangu ikatentha, zomwe zimapangitsa kuti kutentha kuwonongeke komanso kulephera pafupipafupi. Njira yolumikizidwa ya Wuhan Ninestones imachotsa cobalt mwachindunji pa diamondi, ndikuthetsa vuto lalikulu ili.

Njira yodziwika bwino ya kampaniyo yothira mpweya pogwiritsa ntchito mphamvu yamagetsi imagwiritsa ntchito njira yopangira zinthu zosiyanasiyana (HCl, sulfuric acid, Lewis acid) pa kutentha kwa 160°C ndi 0.8MPa, zomwe zimapangitsa kuti cobalt ichotsedwe pa kutentha kwa 580μm m'maola 72. Izi zimachotsa graphitization yoyendetsedwa ndi cobalt ndipo zimachepetsa kusagwirizana kwa kutentha, zomwe zimapangitsa kuti kutentha kukhale kolimba kwambiri.

Kuphatikiza ukadaulo uwu,Dzino la MR1613A6 Diamond Ridgeimapirira kutentha mpaka 1200°C—kupitirira malire a PDCs 750°C omwe ndi achikhalidwe. Mayeso a kumunda ku Utah a 187°C geothermal adawonetsa bwino kuti imagwira ntchito bwino kwa maola opitilira 120, poyerekeza ndi maola 45 a odulira akale, kuchepetsa kuchuluka kwa kugwetsa ndi mphamvu yokweza ndi 30%.

Kapangidwe kake ka MR1613A6 Diamond Ridge Tooth kamakhala ndi mphamvu yodulira kuti miyala isweke bwino, pomwe diamondi yodulidwayo imasunga umphumphu wake ikatentha kwambiri komanso ikagundana. Ndi yabwino kwambiri posinthana mapangidwe ofewa komanso olimba a geothermal, imachepetsa kusweka, ndikuwonjezera moyo wa drill bit. QC yolimba (mayeso ovala a VTL, kusanthula kwa impact) imatsimikizira kuti imagwira ntchito bwino nthawi zonse.

Mogwirizana ndi zomwe msika wa zida za geothermal padziko lonse lapansi ukuyembekezeka kufika pa $31B mu 2025, komanso mothandizidwa ndi mfundo za ku US ndi mayiko opitilira 15 a EGS, ukadaulo wa Wuhan Ninestones womwe wasokonekera ukukwaniritsa zosowa zazikulu zachitukuko pomwe ukuchepetsa kuchuluka kwa mpweya woipa womwe umabwera chifukwa cha mpweya woipa.

Akatswiri akuona kuti izi zimachepetsa zotchinga zakuya za geothermal. Kudalirika kwa MR1613A6 Diamond Ridge Tooth pa kutentha kwambiri kumathandizira malonda, zomwe zimalonjeza kuchepetsa ndalama zomwe zimapangitsa kuti geothermal ikhale gwero lamphamvu loyera. Ndi ma patent 30 ndi kutenga nawo mbali kwa CIPPE, Wuhan Ninestones ikukonzekera kukonza bwino ntchito ya geothermal.Dzino la MR1613A6 Diamond Ridgendi kukulitsa ntchito zake.

Mu 2025, ukadaulo wa PDC wa Wuhan Ninestones unasintha kwambiri mphamvu yamagetsi. Kulimba kwa kutentha ndi kutopa kwa MR1613A6 Diamond Ridge Tooth kumapangitsa kuti ntchito yoboola magetsi ikhale yolimba komanso yothandiza, zomwe zimapangitsa kuti ntchito yokonza magetsi padziko lonse lapansi ikhale yoyera pamene kampaniyo ikutsogolera PDC kuti ikule bwino.
