Inonhuhwirira hydrocarbons ndiyo hwaro hwemhando dzakawanda dzakasiyana dzezvigadzirwa, iyo inonyanya kukosha iyo inoshandiswa mukugadzirwa kwedhayi, polyurethanes uye synthetic fibers.Petrochemical Indasitiri iindasitiri yakazara kwazvo, asi ethylene chinhu chakakosha chigadzirwa, zvakare ndiyo huru olefin zvigadzirwa.Kugadzirwa kwegore negore kwe ethylene muna 2012 kwaive kwemamiriyoni zana nemakumi mana nematatu emamiriyoni.Nhoroondo, kupihwa uye kushandiswa kwe ethylene kwakadzorwa nevehupfumi United States, Western Europe neJapan.Kubva 2009 kana 2010, zvakadaro, mamiriro ezvinhu achinja, nekugadzirwa uye kushandiswa kuchienda kuMiddle East neAsia.Nguva pfupi yadarika apo America shale-gasi boom yakadzosa kuenzana kwehupfumi hwehupfumi uye yakakonzera kuwedzera kukuru kwehunyanzvi hwekugadzira muNorth America.

Ngls kazhinji ine ethane, propane, butane, isobutene, uye pentane.Mamwe acho akanakira iyo petrochemical indasitiri.Ngls yakamboonekwa seyakaderera kukosha-yakawedzerwa ne-chigadzirwa icho Inopisa padyo nemusoro wetsime.Munguva pfupi yapfuura, zvakadaro, vanhu vakazoona zvizere kukosha kwayo se petrochemical raw material.Ndiko kushanduka uku kwakapa simba kupora muNorth America, uye kunyanya muUS petrochemical indasitiri.

Chii chakakoshera kudzoreredza kweindasitiri yepetrochemical yemusika wevharuvhu?

Kudzoreredza muUS petrochemical indasitiri inhau dzakanaka kune vatengesi vemidziyo yeasset, kusanganisira mavharuvhu.Kune mikana yebhizinesi mune yega yega yesimba rekuvandudza zvivakwa.

Kuenderera mberi kwekushandisa shale gasi-rakapfuma mugasi condensate (NGLs) kwakonzera kuvhurwa kwemapurojekiti akawanda ekuchera, zvichikonzera kudiwa kwemhando dzakawanda dzewellhead mavharuvhu Anosanganisira gedhi, globe, choke, cheki, bhora uye mamwe mavharuvhu.Iine angangoita 1,700 rigs ari kushanda muUnited States - zvakanyanya kudarika nyika dzese dzakasanganiswa - kudiwa kwemavharuvhu emumusoro uye kuchave kwakasimba.

Ngls yekugadzira petrochemical inoda yakatsaurirwa pombi network kuti ivaendese kunzvimbo dzekugadzira, senge mayuniti ekupaza kana petrochemical plant.Iyo inoenderana yekuunganidza uye yekufambisa pombi yakapa musika kune pombi vharafu, kunyanya iyo yakazara nzira yekuyerera uye "inogona kufamba bhedhi rakachena" vharafu yebhora, vharafu yegedhi kudiwa kukuru.Uye ma actuators aya mavharuvhu anoda kupetwa nawo anopawo inoyevedza bhizinesi mukana wemusika wemidziyo.

Petrochemical Zvidyarwa zvakanyanya otomatiki uye zvakaoma midziyo.Kubuda kwepagore kwechigadzirwa chitsva chepetrochemical chinogona kunge chakakwira kusvika 1-2 miriyoni matani.Mutengo wechirimwa unobva pakukura kwawo nenzvimbo, asi uchange uri mumadhora mabhiriyoni matatu kusvika kumadhora mana.Mari yevharuvhu pachirimwa ingangoita $35 miriyoni.Kunyange zvichinyatsozivikanwa kuti zvidyarwa zvitsva zvinopa akapfuma uye akazara bhizinesi mikana yeindasitiri yevharuvhu, kuwedzera kwechirimwa uye kudzoreredza kugashira zvitsva zvekugadzira zvinhu zvakakoshawo, kunyanya mumusika weUS.Anenge marudzi ese emavharuvhu anoshandiswa, kusanganisira mavharuvhu ekuvhiya anomhanya anoshandiswa mumafekitari kuchengetedza compressors.
