MDEA desulphurization (desulfurization) skid, yomwe imatchedwanso MDEA sweeting skid, ndi chipangizo chofunikira kwambiri pakuyeretsa gasi kapena kukonza gasi.

MDEA desulfurization skid kwa gasi nthawi zonse anatengera pamene mpweya sulfure wa chakudya mpweya ndi mkulu , ndipo pamene kusankha kuchotsa H2S chofunika kupeza asidi mpweya oyenera Claus chomera processing, ndi zinthu zina zimene angathe kusankhidwa kuchotsa H2S; Pochotsa H2S ndikuchotsa kuchuluka kwa CO2, MDEA ndi alcoholamine ina (monga DEA) ingagwiritsidwe ntchito ngati njira yosakanikirana ya amine;

Njira

Pambuyo pochotsa zodetsa zolimba ndi zamadzimadzi kuchokera ku gasi wodyetsa kudzera pa cholekanitsa ndi cholekanitsa fyuluta, mpweya wodyetsa umachotsedwa munsanja ya valve yoyandama. Njira ya Methyl diethanol (MDEA) imagwiritsidwa ntchito ngati desulphurizer mu nsanja.

Pambuyo pochotsa thovu lamadzi la MDEA pang'ono kuchokera ku gasi kudzera pa cholekanitsa chonyowa chonyowa, mpweya wonyowa umalowa munsanja yopanda madzi.

TEG imagwiritsidwa ntchito kuwononga mpweya wonyowa munsanja ndipo mpweya wowuma wochokera munsanja ya dehydration umagwiritsidwa ntchito. Gasi wachilengedwe amagwiritsidwa ntchito ngati gasi woyenelera kugulitsa kunja.

Madzi olemera a MDEA mu nsanja ya desulfurization amawotcha kuti achotse ma hydrocarbons ndikusefedwa ndi zosefera. Kenako imatenthedwa ndi nthunzi kuti ipangitsenso madzi osauka a MDEA, omwe amaponyedwa ku nsanja ya desulfurization ya cyclic desulfurization.

Gasi wachilengedwe wochokera ku MDEA wolemera wamadzimadzi kung'anima amachotsedwa ndi cholekanitsa madzi acid, ndipo yankho la MDEA lopatulidwa limaponyedwa ku nsanja ya desulfurization. Madzi olemera a TEG omwe amagwiritsidwa ntchito munsanja yochotsa madzi m'thupi amatenthedwa kuti apangitsenso yankho losauka la TEG kudzera pagawo la distillation, thanki yamoto ndi fyuluta. Imapoperedwa ku nsanja ya dehydration chifukwa cha kuchepa kwa madzi m'thupi.

Pambuyo jekeseni H2S mpweya mu asidi gasi yosungirako thanki pa kulekana kwa asidi madzi olekanitsa, izo preheated mu anachita ng'anjo ndi amachitira ndi mpweya kuyamwa ndi mpweya kompresa kupanga SO2, amene amachitira ndi otsala H2S kupanga elemental sulfure, ndiyeno afika sulfure pambuyo kuzirala.
