（2） Izixhobo zokususa i-sulfurization ngegesi yendalo
Iigesi zeFeed zingena kwi iiyunithi zokususa i-sulfurization yegesi yendalo Le yunithi isebenzisa isisombululo se-MDEA ukususa iigesi ze-asidi ezifana ne-CO22 kunye no-H2S kwigesi yokutya.
Igesi yendalo ingena isuka kwinxalenye esezantsi yenqaba yokufunxa kwaye idlule kwinqaba yokufunxa ukusuka ezantsi ukuya phezulu; isisombululo se-MDEA esihlaziyiweyo ngokupheleleyo (ulwelo olungenamanzi) singena sisuka kwinxalenye ephezulu yenqaba yokufunxa kwaye sidlule kwinqaba yokufunxa ukusuka phezulu ukuya ezantsi. Isisombululo se-MDEA kunye negesi yendalo ehamba kwicala elichaseneyo zikwinqaba yokufunxa. Emva kokunxibelelana ngokupheleleyo, i-CO22 kunye no-H2Igesi iyafunxwa ize ingene kwisigaba solwelo. Izinto ezingafunxwayo zikhutshwa phezulu kwinqaba yokufunxwa kwaye zingene kwi-desulfurization gas cooler kunye ne-separator. Igesi ephuma kwi-desulfurization gas separator ingena kwisixhobo sokuphelisa amanzi kwi-molecular sieve, kwaye i-condensate iya kwi-flash tank.
H2Umxholo we-S kwizinto zendalo ezicutshungulwayo ungaphantsi kwe-5 mg/Sm3.
I-MDEA ethathe i-H2I-S ibizwa ngokuba lulwelo olutyebileyo kwaye ithunyelwa kwi-flash evaporation tower. Igesi yendalo ekhutshwa yi-decompression ithunyelwa kwinkqubo yamafutha. Emva kokuba ulwelo olutyebileyo olukhanyayo lutshintshiselana ubushushu nesisombululo (ulwelo oluthambileyo) oluphuma ezantsi kwi-regeneration tower, ubushushu bunyuswa bufikelele kwi-~98°C ukuya kwinxalenye ephezulu ye-regeneration tower, apho ukuhluba kunye nokuhlaziya kwenziwa kwi-regeneration tower de kube i-leaf liquid degree ye-leaf liquid ifikelele kwithagethi.
Ulwelo oluthambileyo oluphuma kwinqaba yokuvuselela ludlula kwisixhobo sokutshintsha ubushushu bolwelo olutyebileyo nolungenamanzi acocekileyo. Ulwelo oluthambileyo luyapholiswa ukuya kuthi ga kwi-104°F. Emva kokuba lucinezelwe yipompo yolwelo oluthambileyo, lungena lusuka kwinxalenye ephezulu yenqaba yokufunxa.
Igesi ekwindawo ephezulu yokuphuma kwenqaba yokuvuselela idlula kwi-carbon dioxide cooler ize ingene kwi-carbon dioxide separator. Igesi ephuma kwi-carbon dioxide separator ithunyelwa kwinkqubo yokukhupha i-carbon dioxide. I-condensate icinezelwa yipompo ye-reflux kwaye ithunyelwe kwinqaba yokuvuselela.
Umthombo wobushushu we-reboiler yenqaba yokuvuselela unikezelwa yioyile yokudlulisa ubushushu kubushushu obuphakathi evela kwinkqubo yeoyile yokudlulisa ubushushu.
Igesi ye-asidi ekhutshwa yinkqubo yokukhupha i-sulfurization ikhutshwa ngqo emoyeni. Ngokusisiseko akukho manzi amdaka akhutshwayo, kwaye amanzi athathwa yigesi ye-asidi akhutshwa ngenkqubo eyongezelelweyo yokulinganisela amanzi angena kwi-sewage system ngenkqubo yokukhupha evaliweyo aze akhutshwe emva kokudlula kunyango.
(3) Ukuphelelwa ngamanzi kwigesi yendalo izixhobo
Esi sixhobo sisebenzisa iteknoloji yokufunxa ubushushu ukuze kwahlulwe kwaye kucocwe igesi. Iteknoloji yokufunxa ubushushu isekelwe ekufunxeni iimolekyuli zegesi kumphezulu wangaphakathi we-adsorbent (izinto eziqinileyo ezinemingxuma). Umthamo wokufunxa we-adsorbent yegesi uyatshintsha ngobushushu kunye noxinzelelo lokufunxa. Phantsi kwemeko yokuba i-adsorbent ifunxa ngokukhetha iinxalenye ezahlukeneyo zegesi, ifunxa iinxalenye ezithile kwigesi exutyiweyo kubushushu obuphantsi kunye noxinzelelo oluphezulu, kwaye iinxalenye ezingafunxwanga ziphuma kumaleko we-adsorber, kwaye zifunxe ezi nxalenye zifunxwanga kubushushu obuphezulu kunye noxinzelelo oluphantsi. Kwi-adsorption elandelayo yobushushu obuphantsi kunye noxinzelelo oluphezulu, iinqaba ezininzi zokufunxa zingasetyenziselwa ukufezekisa injongo yokwahlulwa kwegesi okuqhubekayo.
I iyunithi yokomisa igesi yokondla ixhotyiswe ngee-adsorbers ezintathu zokusebenza ngokutshintsha, kuquka enye yokufunxa, enye yokufutha ngokubandayo, kunye nenye yokufudumeza nokuhlaziya.
Iyunithi yokomisa igesi yokutya isebenzisa inani elincinci legesi yokutya njengento yokuvuthela nokubanda kunye nokuvuselela. Emva kokuba igesi evuselelweyo iphumile kwinqaba yokufunxa, iyapholiswa kwaye yahlulwe ize icinezelwe nge-booster ize ithunyelwe kwinqaba yokufunxa ukuze ifunxe.
Igesi yokuvuselela idlula kuqala kwi-adsorber epholileyo ukusuka phezulu ukuya ezantsi. Emva koko igesi yokuvuselela ifudunyezwa ukuya kubushushu bokuvuselela obuyi-392 ~ 428 ° F yi-heater yokuvuselela, ize ingene ukusuka ezantsi kwe-adsorber ukuze isuse amanzi afunxwe yi-adsorbent. Igesi yokuvuselela iphuma phezulu kwi-dryer, ipholiswe yi-regeneration cooler, ize ingene kwi-regeneration gas separator. Emva kokuba ulwelo lwahlulwe, lungena kwi-supercharger kwaye lucinezelwe kwaye luthunyelwe kwi-adsorption tower ukuze lufunxwe.
Emva kokudlula kule yunithi, amanzi kwigesi yendalo eyomileyo yi-≤ 15 ppm.
