Ma hydrocarbon onunkhira ndiye maziko amitundu yosiyanasiyana yazinthu, zofunika kwambiri zomwe zimagwiritsidwa ntchito popanga utoto, ma polyurethanes ndi ulusi wopangira.Makampani a Petrochemical ndi makampani ochulukirapo, koma ethylene ndi chinthu chofunikira kwambiri, ndiyenso chinthu chachikulu cha olefin.Kupanga kwapachaka kwa ethylene mu 2012 kunali pafupifupi matani 143 miliyoni.M'mbiri, kupezeka ndi kumwa kwa ethylene kumayendetsedwa ndi United States okhwima pazachuma, Western Europe ndi Japan.Kuyambira 2009 kapena 2010, komabe, zinthu zasintha, kupanga ndikugwiritsa ntchito kusamukira ku Middle East ndi Asia.Posachedwapa, kuwonjezereka kwa gasi wa shale ku America kwabweretsanso kukhazikika kwachuma ndikupangitsa kuwonjezeka kwakukulu kwa mphamvu zatsopano zopangira ku North America.

Ngls nthawi zambiri imakhala ndi ethane, propane, butane, isobutene, ndi pentane.Ena mwa iwo ndi abwino kwa mafakitale a petrochemical.Ngls idawonedwa kale ngati chinthu chotsika mtengo chomwe chimawotcha pafupi ndi chitsime.Posachedwapa, anthu adazindikira kufunika kwake ngati mafuta a petrochemical.Kusintha kumeneku ndi komwe kwathandizira kuchira ku North America, makamaka mumakampani aku US petrochemical.

Kodi kufunikira kobwezeretsanso kwamakampani a petrochemical pamsika wama valve ndi chiyani?

Kuchira mumakampani a petrochemical aku US ndi nkhani yabwino kwa ogulitsa zida zazachuma, kuphatikiza ma valve.Pali mwayi wamabizinesi m'mbali zonse za chitukuko cha zomangamanga zamagetsi.

Kupitilirabe kugwiritsiridwa ntchito kwa gasi wolemera kwambiri mu gasi wachilengedwe (NGLs) kwadzetsa kutsegulidwa kwa ntchito zambiri zobowola, zomwe zapangitsa kuti pakhale kufunikira kwamitundu yambiri ya ma valve a Wellhead Kuphatikiza chipata, globe, choke, cheke, mpira ndi ma valve ena.Ndi zida za 1,700 zomwe zikugwira ntchito ku United States - zochulukirapo kuposa dziko lonse lapansi zitaphatikizidwa - kufunikira kwa ma valve oyendetsa bwino kuli ndipo kudzakhala kolimba.

Ngls zopangira petrochemical zimafunikira maukonde odzipatulira a mapaipi kuti awanyamulire kupita kumalo opangirako, monga mayunitsi osweka kapena mafakitale amafuta.Kusonkhanitsa kofananirako ndi mapaipi oyendera apereka msika ku valavu yamapaipi, makamaka njira yonse yoyendetsera ndipo "itha kuyeretsa mkanda" valavu ya mpira, kufunikira kwakukulu kwa valve pachipata.Ndipo ma actuator awa ma valve ayenera kulumikizidwa nawo amaperekanso mwayi wamabizinesi owoneka bwino pamsika wazowonjezera.

Zomera za Petrochemical ndi zida zodziwikiratu komanso zovuta.Kutulutsa kwapachaka kwa chomera chatsopano cha petrochemical kumatha kukhala matani 1-2 miliyoni.Mtengo wa chomeracho umadalira kukula kwake ndi malo ake, koma udzakhala mu $ 3 biliyoni mpaka $ 4 biliyoni.Mtengo wa valve pa chomera chilichonse ungakhale pafupifupi $35 miliyoni.Ngakhale zikudziwika bwino kuti zomera zatsopano zimapereka mwayi wamalonda wolemera kwambiri komanso wochuluka kwambiri pamakampani opanga ma valve, kukulitsa zomera ndi kubwezeretsanso zipangizo zatsopano zopangira zinthu ndizofunikira, makamaka pamsika wa US.Pafupifupi mitundu yonse ya ma valve amagwiritsidwa ntchito, kuphatikizapo ma valve othamanga kwambiri omwe amagwiritsidwa ntchito m'mafakitale kuteteza ma compressor.
