Uruganda rwo mu rwego rwo hejuru Ubushinwa TEG Dehydration Uruganda - MDEA desulphurisation skid yo gutunganya gaze gasanzwe - Rongteng

Ibisobanuro

MDEA desulphurisation (desulfurisation) skid, nanone yitwa MDEA sweeting skid, nigikoresho cyingenzi mugusukura gaze gasanzwe cyangwa gutunganya gaze gasanzwe.

MDEA desulfurisation skid ya gaze karemano ihora yemerwa mugihe karubone ya karubone ya gaze yibiryo iba myinshi, kandi mugihe hakenewe kuvanaho H2S kugirango haboneke gaze ya acide ibereye gutunganya ibihingwa bya Claus, nibindi bintu bishobora guhitamo gukuraho H2S; Iyo ukuyemo H2S no gukuraho umubare utari muto wa CO2, MDEA nizindi alcooline (nka DEA) urashobora gukoreshwa nkuburyo bwa amine buvanze;

Inzira

Nyuma y’imyanda ikomeye n’amazi yakuwe muri gazi yo kugaburira ibinyujije mu gutandukanya no kuyungurura, gaze yo kugaburira isukurwa mu munara wa float valve. Methyl diethanol (MDEA) igisubizo gikoreshwa nka desulphurizer muminara.

Nyuma yo gukuraho agace gato ka MDEA yamazi muri gaze binyuze mumashanyarazi atandukanya amazi, gaze naturel yinjira muminara ya dehydrasi.

TEG ikoreshwa muguhumeka gaze karemano itose muminara kandi gaze yumye ivuye muminara ya dehydrasi. Gazi isanzwe ikoreshwa nka gaze yibicuruzwa byujuje ibyangombwa byoherezwa hanze.

Amazi akungahaye ya MDEA mu munara wa desulfurizasi ni flash ihumeka kugirango ikureho hydrocarbone kandi uyungurure. Noneho hashyutswe nicyuka kugirango habeho kubyara amazi mabi ya MDEA, ashyirwa muminara ya desulfurizasi kugirango cyclic desulfurisation.

Gazi isanzwe ivuye mumazi ya MDEA ikungahaye ikurwaho na aside-amazi, hanyuma igisubizo cya MDEA gitandukanijwe kijugunywa muminara ya desulfurizasi. Amazi akungahaye ya TEG akoreshwa mu munara wa dehydrasiya ashyushye kugirango habeho igisubizo kibi cya TEG ukoresheje inkingi ya distillation, flash tank na filter. Ipompa kuminara ya dehydrasiyo yo kubura amazi.

Nyuma yo gutera gaze ya H2S mukigega cyo kubika gaze ya acide ahantu hatandukanijwe nogutandukanya amazi ya acide, irashyuha mumatanura ya reaction hanyuma ikagira umwuka uhumeka na compressor de air kugirango ube SO2, ifata hamwe na H2S isigaye ikora sulfure yibanze, hanyuma ikabona sulferi nyuma yo gukonja.
