Chomera Choponderezedwa cha Gasi Wachilengedwe

Chomera cha gasi choponderezedwa (chomwe chimadziwikanso kuti CNG) ndi zida zonse zomwe zimaphatikiza kuyeretsedwa kwa gasi, kuponderezana, ndi kusunga.

 

Mfundo yake yaikulu ndiyo kuyeretsa gasi waiwisi kuti achotse zinthu zoipa, kenako nkugwiritsa ntchito ma multi-masitepe compressor kuti achulukitse mphamvu kufika pa 20-25 MPa, kuwasandutsa mpweya wothamanga kwambiri womwe ungathe kusungidwa mu masilinda kapena matanki.

 

Imatha kutulutsa-CNG yabwino kwambiri ndipo ndi imodzi mwa zida zogwiritsiridwa ntchito bwino ndi gasi poyendetsa ndi kugawa magetsi.

Njira yogwirira ntchito ya chomera cha CNG ikhoza kufotokozedwa mwachidule ngati masitepe asanu: kupangira mpweya waiwisi → kuponderezana → kutaya madzi m'thupi & desulfurization → kusungirako → kutulutsa kwazinthu

Masiku ano, pamene kugwiritsa ntchito mphamvu zoyera kukuchulukirachulukira, kapangidwe kauinjiniya woyengedwa ndikofunikira kuti tikwaniritse kupanga bwino komanso kotetezeka kwa zomera za Compressed Natural Gas. Takhazikitsa gulu laukatswiri waukadaulo lomwe lakhala ndi zaka zopitilira 25 zaukadaulo pantchito yakuponderezedwa kwa gasi, ndikumadziwa bwino zofunikira zapakhomo ndi zapadziko lonse lapansi monga ISO, API, ASME, ndi EN. Kutengera mawonekedwe a gasi waiwisi (kuphatikiza chiŵerengero cha methane ndi mawonekedwe odetsedwa) ndi malo ogwiritsira ntchito (mwachitsanzo, kuthamangitsa galimoto kapena gasi wamakampani) pama projekiti osiyanasiyana, timapereka mayankho amunthu payekha. Timayang'ana kwambiri kukhathamiritsa kasinthidwe ka siteji ya kompresa, kugwiritsa ntchito bwino kwa intercooler, ndi kulumikizana kwa dongosolo loyeretsera, zomwe zitha kuchepetsa kugwiritsa ntchito mphamvu ndi 5% -8% poyerekeza ndi njira wamba. Nthawi zonse timatsatira lingaliro lakusintha mwamakonda kuonetsetsa kuti chomera chilichonse chikugwirizana bwino ndi zofunikira zake zogwirira ntchito.

Munthawi yonse ya polojekiti kuyambira kukonzekera mpaka kuyitanitsa, kampani yathu imakwaniritsa miyezo ya ISO9001 Quality Management System ndi ISO14001 Environmental Management System. M'gawo lakapangidwe kazinthu, timagwiritsa ntchito mapulogalamu aukadaulo monga Aspen HYSYS poyeserera kachitidwe ka kompresa kuonetsetsa kukhazikika kwa kuthamanga kwake. Zipangizo zonse zofunika kwambiri, kuphatikizapo ma compressor, -mavavu othamanga kwambiri, ndi zitsime zosungira gasi, zimawunikiridwa ndi mabungwe odziyimira pawokha-achipani chachitatu kuti zitsimikizire kuti zikutsatira zofunikira za zida zokakamiza monga ASME BPVC Section VIII. {{7}Kuwotchera mapaipi akuthamanga kwambiri kumatsatira mosamalitsa njira zovomerezeka, kuphatikiza-njira zosawononga zoyezera monga Ultrasonic Testing (UT) ndi Penetrant Testing (PT), kuonetsetsa kuti malo olumikizirana ndi odalirika. Kuyesa kosasunthika kwa maola 72 kumachitika ntchito isanamalizidwe kuti zitsimikizire bwino momwe chipangizocho chimagwirira ntchito potengera kayendedwe kake, kupanikizika kwamakina, komanso kuyera kwa gasi. Ndondomeko yonseyi yokhazikika imapereka chitsimikizo cholimba cha kudalirika kwa khalidwe la polojekiti komanso nthawi yoperekera.

Ubwino wazinthu ndiye maziko ofunikira kuwonetsetsa kuti CNG ili ndi chitetezo komanso chokhazikika. Fakitale iliyonse imakhala ndi malamulo okhwima: makina osindikizira amakhala ndi zoteteza kuchulukirachulukira komanso{1}}kuwunika kwenikweni kutentha kwanthawi kuti zitsimikizire kuti zikugwira ntchito mosalekeza; mkulu{{2}magawo osungira gasi amapangidwa motsatira kwambiri GB 150 kapena ASME ndi moyo wautumiki wa zaka zosachepera 20; chipangizo choyeretsera gasi chimatsimikizira kuti CNG yopangidwa ikukwaniritsa zofunikira zamayiko monga GB 18047, ndipo chiwongola dzanja chamankhwala nthawi zonse chimakhala ndi 100%. Avereji yamavuto{{8}nthawi yogwira ntchito mwaulere pagulu lonse la zida imapitilira maola 8000, zomwe zimakuthandizani kuti{10}}zigwire bwino ntchito kwanthawi yayitali.

Kuti muwonetsetse kupezeka kwa CNG mosalekeza, -pamwamba kwambiri pambuyo-ntchito zogulitsa ndizofunikira. Mukalandira pempho lochokera kwa wogwiritsa ntchito, gulu lathu lothandizira zaukadaulo likhazikitsa njira yoyankhira 24/7 nthawi yomweyo ndikulonjeza kuti lipereka yankho koyamba pasanathe maola 8 kudzera pama foni, maimelo, kapena{6}}zofufuza zapatsamba. Pazinthu zomwe zingathe kuthetsedwa patali monga kusintha kwamakanikizidwe ndi kuzindikira kwa ma alarm, timatsimikizira kuti timathandizira kumaliza ntchitoyi mkati mwa maola 24; ngati makina akulephera kutsata{9}}kukonza malo, mainjiniya atha kutumizidwa kumadera akumudzi mkati mwa maola 48 komanso m'mayiko ena mkati mwa maola 72. Kuphatikiza apo, timapereka ntchito zokonzera zokonzekera kuphatikiza kusinthira mafuta a compressor ndikuyeretsa zosefera kuti tiwonjezere moyo wautumiki wa zida.

Mafakitale Athu Agasi Opangidwa Mwachilengedwe asonyeza kudalirika komanso kugwira ntchito moyenera-pamafakitale akulu akulu, ndipo azindikiridwa ndi mabizinesi ambiri otsogola pamakampani opanga magetsi ndi zoyendera, kuphatikiza makampani odziwika padziko lonse lapansi monga PetroChina, Sinopec, Gazprom, ndi makampani amafuta opanda mphamvu.

Pankhani ya njira zogwirira ntchito limodzi, sitimangopereka njira zonse-zopereka njira zobweretsera makiyi ophatikizika, kuphatikiza kupanga, kukhazikitsa, ndi kutumiza komanso kupereka zitsanzo zosinthika monga kubwereketsa zida kapena mapangano agasi (ndife tili ndi udindo wogwirira ntchito zamafakitale ndikupereka CNG kwa makasitomala) molingana ndi zosowa zenizeni za makasitomala, kuthandiza makasitomala kusankha njira yoyenera kwambiri yopangira ndalama pazochitika zawo.
