Ukuqaliswa kwenkqubo yesityalo sokukhupha amanzi emzimbeni se-TEG kwi-skid yokunyanga igesi yendalo
Indlela yokufunxa isinyibilikisi yenye yezona zisetyenziswa kakhulu inkqubo yokuphelelwa ngamanzi emzimbeni kwishishini lokucubungula igesi yendalo, Ukuphelelwa ngamanzi emzimbeni yi-TEG (i-triethylene glycol dehydration) idla ngokusetyenziswa njengohlobo lweSolvent. Isebenzisa umgaqo wokufunxa kwaye isebenzisa izinto ze-glycol (ezifana ne-triethylene glycol) njengezifunxi ukuze iqhagamshelane ngokupheleleyo negesi yendalo, idlulisele amanzi kwisinyibilikisi ukuze ifumane ukopha.
Emva kokuphuma kwinqaba, ingena kwi-casing heat exchanger kwaye itshintshiselana nobushushu ne-hot lean glycol ngaphambi kokungena kwinqaba ukunciphisa ubushushu be-TEG. Igesi yendalo emva kokutshintshwa kobushushu ingena kwi-filter separator ukuze yahlule i-glycol ethwalwayo ize ingene kwipayipi yangaphandle. I-TEG etyebileyo efunxe umswakama kwigesi yendalo iphuma kwinqaba yokufunxa kwaye ingene kwi-liquid level regulating valve, kwaye emva kokunciphisa uxinzelelo, ingena kwi-reflux cooling coil ephezulu kwikholamu yokulungisa ulwelo etyebileyo kwaye itshintshiselana nobushushu nomphunga oshushu owenziwe kwi-reboiler ukuze inike i-column top reflux. Emva kokubonelela ngomthamo wokupholisa we-column top reflux, ifudunyezwa ukuya kuthi ga kwi-50 ℃, ize iphume kwi-coil iye kwi-TEG flash tank. I-glycol etyebileyo ixinzelelwa ukuya kwi-0.4mpa~0.6mpa kwi-flash tank, kwaye igesi ye-hydrocarbon kunye nezinye iigesi ezinyibilikisiweyo kwi-TEG ziyacinywa, kwaye le nxalenye yegesi isetyenziswa njengegesi yamafutha yokutsha kwe-reboiler.
I-TEG yolwelo olutyebileyo olukhanyayo ingena kwi-mechanical filter ukuze ihluze ukungcola koomatshini, ize ingene kwi-activated carbon filter ukuze ifunxe ngakumbi izinto ze-hydrocarbon ezinyibilikiswe kwi-TEG kunye nezinto ezonakaliswe yi-TEG. Emva koko ingena kwi-plate-type lean-rich liquid heat exchanger, itshintshise ubushushu ne-lean TEG yobushushu obuphezulu evela kwi-heat exchange buffer tank kwinxalenye esezantsi ye-TEG reboiler, ize ifudumale ukuya kuthi ga kwi-~150 °C ukuze ingene kwikholamu yokulungisa ulwelo olutyebileyo.
Kwi-TEG reboiler esezantsi kwikholamu yokulungisa, i-TEG ifudunyezwa ukuya kwi-193 ℃, kwaye amanzi kwi-TEG ayaqhekezwa aze akhutshwe phezulu kwikholamu yokulungisa ngokusebenzisa isiphumo sokuqhekezwa kwikholamu yokulungisa. I-glycol ethambileyo enoxinzelelo olumalunga ne-99% (wt) idlula kwikholamu yokususa ulwelo oluthambileyo kwi-reboiler ukuya kwi-tank yokutshintsha ubushushu ye-TEG esezantsi. Phantsi kwesenzo segesi eyomileyo kwikholamu yokususa ulwelo oluthambileyo, uxinzelelo lwe-glycol ethambileyo engena kwi-tank yokutshintsha ubushushu inokufikelela kwi-99.5% ~ 99.8%.
Kwitanki ye-glycol buffer, i-lean glycol enobushushu obumalunga ne-193 °C ingena kwi-lean-rich glycol heat exchanger ukuze itshintshise ubushushu ne-glycol etyebileyo, kwaye ubushushu buyehla bufikelele kwi-100 °C bungene kwimpompo. I-lean liquid TEG ipompelwa kwi-gas-liquid heat exchanger ngaphandle kwe-absorption tower, kwaye emva kokuba ipholile nge-gas heat exchanger iphuma kwi-tower, ingena phezulu kwi-absorption tower ukusuka kwinxalenye ephezulu ye-casing ukuze igqibezele ukujikeleza kwe-solvent.
