Gasi rechisikigo rinoburitswa rine huwandu hwakati hweCO2 ine acidic, izvo zvinogona kukonzera matambudziko akadai sekudzikira kwehuwandu hwemacalorie uye ngura yemapaipi. Saka, kurapwa kwekubvisa carbonization kunodiwa usati watakura uye kushandisa mapaipi.
Zvichienderana nefomura yekukosha kwemafuta egasi rechisikigo muchiyero chenyika (GB/T 11062-2014), zvinogona kuverengerwa kuti 10mol% CO2 ichakonzera kudzikira kwemafuta emethane ne9.80% pa cubic meter. Kana CO2 ikabatana neutsi hwemvura uye ine kumanikidzwa kwechikamu kunodarika 207kPa, inokonzera ngura yakakura kumidziyo nemapaipi, uye mamwe matanho ekudzivirira ngura anofanira kutorwa. Nokudaro, gasi rechisikigo rinofanira kubviswa zvakasimba muCO2 risati raendeswa kumapaipi ekutengeserana.
Maitiro eMDEA anoshandiswa kubvisa CO2 kubva mugasi rechisikigo.
MDEA Hunhu hwefizikisikemikari uye musimboti we decarburization
MDEA, zita resainzi rekuti N -methyldiethanolamine, imvura isina ruvara kana kuti yero zvishoma ine viscous.
Fomura yemasero: CH3N(CH2CH2OH)2,
Pokufashaira: 246~249 ℃ /760mmhg; giravhiti chaiyo: 1.0425g/ml (20 ℃);
Nzvimbo yechando: -21 ℃ (kuchena 99%); viscosity: 101Cp (20 ℃);
Inogona kusanganiswa nyore nyore nemvura, ethanol, ether, nezvimwewo; alkaline shoma mumvura; makemikari anoitika mu acid carbon dioxide nehydrogen sulfide gas, uye kana paine kumanikidzwa kwakanyanya, carbon dioxide nehydrogen sulfide gas dzine zvakawanda. Saka nzira yese yekunyudzwa ndeyekunyudzwa kwemuviri nemakemikari.
Mvura ine hupfumi hweMDEA mushure mekunwa hydrogen sulfide necarbon dioxide inopinda muflash tank kuti iparadze flash, uye yozotumirwa ku regeneration tower. Mvura ine hupfumi inopiswa uye inoora pasi pe tower kuti ibudise carbon dioxide nehydrogen sulfide zvakakwana. Panguva imwe chete, gasi riri pasi pe tower rinokwira kuti riite secondary stripping effect pamvura ine hupfumi pamusoro pe tower. Saka maitiro ese e regeneration ndiwo maitiro e physical uye chemical regeneration. Maitiro chaiwo emakemikari ndeaya anotevera:
R2R'N + H2S R2R'NH +HS (kuita pakarepo)
R2R'N+CO2+ H2O R2R'NH +HCO3 (kuita zvishoma nezvishoma)
Hengzhong inyanzvi mukurapa matsime emumunda ane gasi, kucheneswa kwegasi rechisikigo, kudzoreredzwa kweLPG, Chirimwa cheLNG uye seti yejenareta yegesi yechisikigo.
