Mankhwala a Methyl diethanol (MDEA) amagwiritsidwa ntchito ngati desulphurizer yochotsera H2S mu mpweya wachilengedwe.

Chiyambi cha chipangizo chokometsera mpweya wachilengedwe

Pambuyo poti zinthu zodetsedwa ndi zolimba ndi zamadzimadzi zachotsedwa mu mpweya wodyetsa kudzera mu separator ndi fyuluta separator, mpweya wodyetsa umachotsedwa mu nsanja ya valavu yoyandama. Methyl diethanol (MDEA) solution imagwiritsidwa ntchito ngati desulphurizer mu nsanja.

Pambuyo pochotsa thovu laling'ono la MDEA kuchokera mu mpweya kudzera mu cholekanitsa chonyowa, mpweya wachilengedwe wonyowa umalowa mu nsanja ya madzi osowa.

TEG imagwiritsidwa ntchito kusungunula mpweya wachilengedwe wonyowa womwe uli mu nsanja ndipo mpweya wouma wochokera mu nsanja yosungunula madzi umagwiritsidwa ntchito. Mpweya wachilengedwe umagwiritsidwa ntchito ngati mpweya woyenerera wotumizidwa kunja.

Madzi olemera a MDEA omwe ali mu nsanja yochotsera sulfur amasanduka nthunzi kuti achotse ma hydrocarbons ndikusefedwa ndi zosefera. Kenako amatenthedwa ndi nthunzi kuti aberekenso madzi osauka a MDEA, omwe amapopedwa kupita ku nsanja yochotsera sulfur kuti achotse sulfur.

Mpweya wachilengedwe wochokera ku MDEA wolemera mu madzi umachotsedwa ndi cholekanitsa madzi ndi asidi, ndipo yankho la MDEA lolekanitsidwa limapopedwa kupita ku nsanja yochotsera sulfurization.

Madzi olemera a TEG omwe amagwiritsidwa ntchito mu nsanja yochepetsera madzi m'thupi amatenthedwa kuti aberekenso njira yochepetsera madzi m'thupi kudzera mu distillation column, flash tank ndi fyuluta. Amapopedwa kupita ku nsanja yochepetsera madzi m'thupi kuti madzi asamathenso madzi m'thupi.

Pambuyo pobaya jekeseni ya H₂Mpweya wa S (S)kuchotsa sulfide kuchokera ku mpweya wachilengedwe）Mu thanki yosungiramo mpweya wa asidi pamalo olekanitsira madzi a asidi, imatenthedwa mu uvuni wa reaction ndipo imayanjana ndi mpweya womwe umayamwa ndi compressor ya mpweya kuti ipange SO₂, zomwe zimagwirizana ndi H yotsalayo₂S kuti ipange sulfure yoyambira, kenako imalandira sulfure ikazizira. Mwa izi, titha kumaliza njira ya Kuchotsedwa kwa H2S kuchokera ku gasi wachilengedwe.
