2. Inkcazo yetekhnoloji yenkqubo

Igesi yendalo emanzi emanzi idlula kwiisahluli sesihluziukwahlula amathontsi angama-5 μm nangaphezulu, uze ungene kwisihluli segesi-ulwelo sesixhobo sokukhupha amanzi emzimbeni ukuze wahlukanise ulwelo olukhululekileyo. Igesi eyahlukileyo ingena kwicandelo lokufunxa ngepayipi enyukayo yenqaba yokufunxa. I-triethylene glycol ehlaziyiweyo itshizwa phezulu kwinqaba yokufunxa, kwaye idibana ngokupheleleyo negesi yendalo ukusuka ezantsi ukuya phezulu kwinqaba yokufunxa ukuze kwenziwe udluliselo olukhulu kunye notshintshiselwano ukususa umswakama. Igesi yendalo esuswe umswakama isuswa kwisiqokeleli senkukuma senqaba ukuze kususwe amathontsi e-glycol amakhulu kune-5 μm ize iphume kwinqaba.

Emva kokuphuma kwinqaba, ingena kwi-casing heat exchanger kwaye itshintshiselana nobushushu ne-hot lean glycol ngaphambi kokungena kwinqaba ukunciphisa ubushushu be-triethylene glycol. Igesi yendalo emva kokutshintshwa kobushushu ingena kwi-filter separator ukuze yahlule i-glycol ethwalwayo ize ingene kwipayipi yangaphandle. I-triethylene glycol 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 kuma-50 ℃, ize iphume kwi-coil iye kwi-triethylene glycol flash tank. I-glycol etyebileyo ixinzelelwa ukuya kwi-0.4mpa~0.6mpa kwi-flash tank, kwaye i-hydrocarbon gas kunye nezinye iigesi ezinyibilikisiweyo kwi-triethylene glycol ziyacinywa, kwaye le nxalenye yegesi isetyenziswa njengegesi yamafutha yokutsha kwe-reboiler.

I-triethylene glycol etyebileyo ekhanyayo ingena kwi-mechanical filter ukuze ihluze ukungcola koomatshini, ize ingene kwi-activated carbon filter ukuze ifunxe ngakumbi izinto ze-hydrocarbon ezinyibilikiswe kwi-triethylene glycol kunye nezinto ezonakaliswe yi-triethylene glycol. Emva koko ingena kwi-plate-type lean-rich liquid heat exchanger, itshintshise ubushushu ne-lean-high-temperature triethylene glycol evela kwi-heat exchange buffer tank kwinxalenye esezantsi ye-triethylene glycol reboiler, kwaye ifudumale ukuya kuthi ga kwi-~150 °C ukuze ingene kwikholamu yokulungisa ulwelo etyebileyo.

Kwi-triethylene glycol reboiler esezantsi kwikholamu yokulungisa, i-triethylene glycol ifudunyezwa ukuya kwi-193 ℃, kwaye amanzi kwi-triethylene glycol ayaqhekezwa aze akhutshwe phezulu kwikholamu yokulungisa ngokusebenzisa isiphumo sokwahlulahlula kwikholamu yokulungisa. I-lean glycol enoxinzelelo olumalunga ne-99% (wt) idlula kwikholamu yokususa ulwelo oluthambileyo kwi-reboiler ukuya kwi-triethylene glycol heat exchange buffer tank esezantsi. Phantsi kwesenzo segesi eyomileyo kwikholamu yokususa ulwelo oluthambileyo, uxinzelelo lwe-lean glycol olungena kwi-heat exchange buffer tank lunokufikelela 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 triethylene glycol iphonswa 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.

Igesi eyomileyo ekhutshwa kwicandelo lombhobho wegesi eyomileyo kwindawo yokuphuma kwenqaba yokufunxa yigesi esusa igesi kwikholamu yokulungisa.
