Maitiro ekudzoreredza mahydrocarbon akareruka kubva mugasi rinosanganisirwa muminda yemafuta (1)
Iyo kudzoreredzwa kwemahydrocarbons echiedza kubva mugasi rinobatanidzwa muminda yemafuta inzira yakakosha muindasitiri yemafuta negasi. Gasi rinobatanidzwa, rinowanzo kuwanikwa pamwe chete neoiri isina kuchena, rine zvinhu zvinokosha zvakaita semafuta echisikigo (NGL) uye gasi repetroleum rakanyungudutswa (LPG). Kuwana mahydrocarbon aya echiedza hakungobatsiri chete pakukosha kwegasi asiwo kunobatsira mukuderedza kuburitswa kwegasi rinopisa. Muchinyorwa chino, tichaongorora kukosha kwekudzorerwa kweNGL neLPG kubva mugasi rinobatanidzwa uye matekinoroji anobatanidzwa mukuita uku.
Kudzorerwa kweNGL kubva mugasi rakabatana zvinosanganisira kupatsanurwa nekuburitswa kwezvinwiwa zvegasi rechisikigo zvakaita se ethane, propane, uye butane. Zvikamu izvi zvine kukosha kukuru kwekutengeserana uye zvinoshandiswa sezvikafu zvezvirimwa zve petrochemical, pamwe nekugadzira mapurasitiki, rabha yekugadzira, nezvimwe zvigadzirwa zvemaindasitiri. NGL kubva kugasi rakabatana zvakakosha pakuwedzera kugona kwehupfumi hwegasi uye kuderedza kutambisa zviwanikwa zvinokosha.
Tsananguro pfupi yemaitiro acho ndeiyi:
1) Sisitimu yekusanganisa nekusimudzira gasi rechisikigo
1) Tsananguro yemaitiro
Gasi rinoiswa mumhepo rinomanikidzwa kusvika pa 0.3 MPaG uye rozosanganiswa neLow Pressure stream rozomanikidzwa kusvika pa 3.9 MPaG. Rwizi rwakasanganiswa runozosanganiswa neHigh Pressure ropinda mumudziyo uri pasi.
2) Magadzirirwo edhizaini
Kugona kwekugadzira gasi rekudya:
Kumanikidzwa Kwakanyanya: 12500 Nm3/h;
Kudzvinyirirwa Kwakaderera: 16166.7 Nm3/h;
2) Sisitimu yekubvisa mvura kubva mugasi rechisikigo
1) Tsananguro yemaitiro
Kuvapo kwehunyoro mugasi rechisikigo kunowanzo kukonzera migumisiro yakakomba: hunyoro negasi rechisikigo zvinogona kugadzira hydrate kana aizi yekuvhara mapaipi pasi pemamwe mamiriro ezvinhu.
Kupedza mvura negasi rechisikigo kunoshandisa nzira yekunyungudutsa mvura nesefa yemamorekuru. Sezvo sefa yemamorekuru iine sarudzo yakasimba yekunyungudutsa mvura nesefa ine hunhu hwakawanda hwekunyungudutsa mvura nemhepo shoma, chishandiso ichi chinoshandisa sefa ye4A molecular sesefa inonyungudutsa mvura nesefa.
Chigadzirwa ichi chinoshandisa nzira ine shongwe mbiri kuti chitore hunyoro, chinoshandisa nzira yeTSA kuongorora hunyoro hwakanyungudutswa mu molecular sefa, uye chinoshandisa nzira ye condensation kuti chiunganidze uye chiparadzanise hunyoro hwakabviswa kubva mu adsorbent.
2) Magadzirirwo edhizaini
Kugona kwekugadzirisa gasi rekudya 70 × 104 Nm3/d
Kumanikidzwa kweAdsorption 3.5MPaG
Kupisa kweAdsorption 35 ℃
Kumanikidzwa kwekuvandudzwa kwemuviri 3.5MPaG
Kupisa kwekuvandudzwa ~260 ℃
Mafuta ekupisa anodzoreredza kupisa
Zviri muH2O mugasi rakacheneswa ＜ 5 ppm
