I-skid ye-100MMSCFD yokususa i-sulphurization yegesi yendalo enenkqubo yesisombululo se-MDEA
ISichuan Hengzhong Clean Energy Equipment Co., Ltd., yazalwa ngo-2012 kwaye singabonelela ngezisombululo kunye neephakheji zezixhobo zonyango lwentloko yemithombo, izixhobo zokupholisa igesi yendalo, iphakheji yokubuyisa isalfure, Iyunithi yokukhupha i-LPG kunye neyunithi yokubuyisela i-NGL, Isityalo sokunyibilikisa ulwelo se-LNG, iyunithi yokuvelisa i-hydrogen, iphakheji yokukhupha i-helium, iiseti zejenereyitha yegesi.
I-desulphurization skid epheleleyo iquka iinkqubo ezintathu: inkqubo yenkqubo, inkqubo yolawulo lwezixhobo kunye nenkqubo yokusetyenziswa. Ngokwemithombo eyahlukeneyo yomoya, inokutshintshwa.
Ngokwemeko yokwenyani yomthombo wegesi, samkela inkqubo engcono kakhulu kunye neyona ndlela ingabizi kakhulu ukuhlangabezana neemfuno ezahlukeneyo zabathengi. Izixhobo ezifakwe kwi-skid zenza ukuthuthwa nokufakwa kube lula ngakumbi.
- Inkqubo ephambili yokusebenzisa isisombululo se-MDEA ukususa i-CO2 kunye ne-H2S:
Indalo evela phezulu ingena kwiyunithi yokususa i-asidi, esebenzisa isisombululo se-MDEA ukususa iigesi ze-asidi ezifana ne-CO2\H2S kwigesi eluhlaza.
Igesi yendalo ingena kwi-absorber isuka ezantsi ize ihambe iye phezulu. Isisombululo se-MDEA esihlaziyiweyo ngokupheleleyo (isisombululo esingenamaqondo) singena kwi-absorber isuka phezulu ize ihambe iye ezantsi. I-countercurrents yesisombululo se-MDEA kunye negesi yendalo zidibana ngokupheleleyo ne-absorber, zifunxa i-CO2 kunye ne-H2S kwigesi kwaye zidluliselwe kwisigaba solwelo. Izinto ezingafunxwanga zitsalwa phezulu kwe-absorber kwaye zingene kwi-deasidification gas cooler kunye ne-separator. Igesi ephuma kwi-deasidification gas separator ingena kwi-feed gas pre-cooling unit, kwaye i-condensate ithunyelwa kwi-flash tank.
TUmxholo we-CO2 kwigesi yendalo enyangiweyo ungaphantsi kwe-50 PPM, kwaye umxholo we-H2S ungaphantsi kwe-4 PPM.
Isisombululo se-MDEA esifunxe i-CO2 kunye ne-H2S, esibizwa ngokuba lulwelo olutyebileyo, sithunyelwa kwi-flash tower, apho uxinzelelo luncitshiswa khona kwaye igesi yendalo ekhanyayo ephumayo ithunyelwa kwinkqubo yokukhupha umoya. Ulwelo olutyebileyo olukhanyayo emva koko lutshintsha ubushushu nesisombululo (ulwelo oluthambileyo) oluphuma ezantsi kwi-regeneration tower. Ubushushu bunyuswa bufike kwi-~203 °F kwaye buthunyelwe kwinxalenye ephezulu ye-regeneration tower, apho ihluthwa khona kwaye ivuselelwa de ulwelo oluthambileyo lufikelele kuxinzelelo olujoliswe kulo.
Ulwelo oluthambileyo oluvela kwinqaba yokuvuselela ludlula kwi-lean-rich liquid heat exchanger kunye ne-lean liquid cooler, lupholiswe ukuya kwi-113 °F, kwaye lucinezelwe yipompo yolwelo oluthambileyo ngaphambi kokuba lungene kwinxalenye ephezulu yenqaba yokufunxa.
Igesi ephumayo esuka phezulu kwinqaba yokuvuselela idlula kwi-acid gas cooler ize ingene kwi-acid gas separator. Igesi ephuma kwi-acid gas separator ithunyelwa kwinkqubo yokukhupha i-acid gas, kwaye i-condensate ibuyela kwi-MDEA buffer tank.
Umthombo wobushushu we-regeneration tower reboiler ufudunyezwa nge-thermal oil.
Izixhobo eziphambili zenkqubo zale yunithi yinqaba yokufunxa kunye nenqaba yokuvuselela.

- Inkqubo yokulawula izixhobo
Ukuze kujongwe ngempumelelo inkqubo yokuvelisa iseti epheleleyo yezixhobo, kwaye kuqinisekiswe ukusebenza okuthembekileyo kunye nokusebenza okulula kunye nokugcinwa, inkqubo yolawulo lwezixhobo ibandakanya ikakhulu:
Inkqubo yolawulo olusasazwayo (i-DCS)
Inkqubo yeZixhobo zoKhuseleko (i-SIS)
Inkqubo yeAlarm yoMlilo kunye neGesi (FGS)
Umabonakude ojikelezayo (i-CCTV)
Inkqubo yohlalutyo
- Inkqubo yokusetyenziswa
Le nkqubo ibandakanya ikakhulu: iyunithi yomoya wesixhobo, iyunithi yenitrogen, iyunithi yeoyile yokudlulisa ubushushu, iyunithi yamanzi angenatyuwa kunye neyunithi yamanzi ajikelezayo okupholisa.
