Nzvimbo dzekushandisa dzeakakosha alloys muindasitiri yepetroleum yepombi dzesimbi isina tsvina
Petroleum yekuongorora uye kusimudzira iindasitiri yemhando dzakasiyana-siyana, tekinoroji- uye capital-intensive indasitiri inoda huwandu hukuru hwezvinhu zvesimbi uye zvigadzirwa zvesimbi zvine zvivakwa zvakasiyana uye mashandisiro. Nekuvandudzwa kweakanyanya kudzika uye ekupedzisira-akarerekera emafuta uye gasi matsime nemafuta negasi minda ine H2S, CO2, Cl-, nezvimwewo, kushandiswa kwesimbi isina tsvina zvinhu zvine anti-corrosion zvinodiwa kuri kuwedzera.
Kuvandudzwa kweindasitiri yepetrochemical pachayo uye kuvandudzwa kwemidziyo yepetrochemical kwaisa mberi zvinodiwa zvepamusoro pamhando nekushanda kwesimbi isina tsvina, inoda kuti simbi isina ngura isaita ngura uye inoshingirira kune tembiricha yepamusoro uye yakaderera. Mamiriro acho haana kusununguka asi anoomesera. Panguva imwecheteyo, iyo petrochemical indasitiri ndeyepamusoro-tembiricha, yakanyanya-kudzvanywa, uye ine muchetura indasitiri. Yakasiyana nemamwe maindasitiri. Migumisiro yekushandiswa kwakasanganiswa kwezvinhu haisi pachena. Kamwe chete kunaka kwesimbi isina tsvina muindasitiri yepetrochemical haigone kuvimbiswa, mhedzisiro yacho ichave yakaipa. Naizvozvo, makambani emumba esimbi asina tsvina, kunyanya makambani epombi dzesimbi, anofanirwa kuvandudza zvigadzirwa zvehunyanzvi uye kuwedzera kukosha kwezvigadzirwa zvavo nekukurumidza sezvinobvira kuti vatore musika wechigadzirwa chepamusoro.
Musika unogona kuitika weindasitiri yepetrochemical yakakura-dhayamita mapaipi emafuta anopwanya mavira uye akadzika-tembiricha ekufambisa pombi. Nekuda kwekukosha kwavo kupisa uye kusimba kwekudzivirira zvinodiwa uye kusagadzikana kwekuisa nekugadzirisa zvishandiso, zvishandiso zvinofanirwa kuve nehupenyu hurefu hwehupenyu hwesevhisi, uye magadzirirwo emagetsi uye kuita kwepombi zvinoda kuvandudzwa kuburikidza nekuumbwa kwezvinhu uye nzira dzakakosha dzekurapa kupisa. . Imwe musika inogona kuve yakakosha mapaipi esimbi eindasitiri yefetereza (urea, phosphate fetereza), mamakisi makuru esimbi ari 316Lmod uye 2re69.
Inowanzo shandiswa mumareactor mumidziyo yepetrochemical, mapombi echitsime chemafuta, matanda akakwenenzverwa mumatsime emafuta anoodza, mapaipi anotenderera muvira re petrochemical, uye zvikamu pamafuta uye gasi kuchera, nezvimwe.
