3.2.2.2 Ukususwa kwemercury nokomisa igesi yegesi

1）Inkcazo yenkqubo

Irhasi yendalo esuka kwiyunithi yegesi yokutya ingena kwisulphur efakwe kwikhabhoni adsorber. I-Mercury iphendula kunye nesalfure kwi-sulphur efakwe kwikhabhoni esebenzayo ukuvelisa i-mercury sulfide, efakwe kwikhabhoni esebenzayo, ukuze kuphunyezwe injongo yokususa imekyuri. Isiqulatho semekyuri yerhasi yendalo evela kwisisusa imekyuri ingaphantsi kwe-0.01μg/Nm³.

Esinye isikhiphi semekyuri siya kusekwa, kunye nesalfure efakwe kwikhabhoni esebenzayo iya kutshintshwa ngokwemiqathango yovavanyo.

Igesi yendalo emva kokususwa kwe-mercury ingena kwiyunithi yokomisa. Iyunithi ithatha itekhnoloji ye-adsorption swing yobushushu bokwahlula igesi kunye nokucocwa. Ubushushu be-adsorption yetekhnoloji ye-adsorption isekelwe kwi-adsorption yomzimba yeemolekyuli zegesi kumphezulu wangaphakathi we-adsorbent (izinto eziqinileyo eziqinileyo), kwaye isebenzisa iimpawu zokuthi amandla adsorption e-adsorbent yotshintsho lwegesi kunye nobushushu obuhlukeneyo kunye noxinzelelo. uxinzelelo, kwaye amacandelo angafakwanga aphuma nge-adsorber layer. Ezi zixhobo ze-adsorbed zichithwa kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphantsi kwiqondo lokushisa eliphantsi elilandelayo kunye ne-high-pressure adsorption. Iinqaba ezininzi ze-adsorption zingasetyenziselwa ukufezekisa injongo yokwahlukana kwegesi eqhubekayo.

Ukomisa igesi yokutya kunye neyunithi yokususwa kwe-hydrocarbon enzima ixhotyiswe ngee-adsorbers ezintathu zokutshintsha ukusebenza, enye ye-adsorption, enye yokuvuthela okubandayo kunye neyokuvuselela ukufudumeza.

Irhasi yokutya esuka kwi-demercuration tower ingena phezulu kwi-adsorber, isusa amanzi nge-molecular sieve adsorption, iphuma ezantsi kwe-adsorber, kwaye ingena kwi-feed gas heavy hydrocarbon iyunithi yokususa emva kokuphelelwa ngamanzi emzimbeni.

Iyunithi yokomisa igesi yokutya isebenzisa isixa esincinci segesi yokutya njengendlela yokuvuthela okubandayo kunye nokuvuselela. Emva kokuba irhasi yokuhlaziya ishiya inqaba ye-adsorption, ibuyela kwindawo yokungena kwinqaba yokomisa kwimeko ye-adsorption emva kokupholisa kunye nokwahlula.

Irhasi yokuhlaziya kuqala idlula kwi-adsorber epholileyo ukusuka phezulu ukuya ezantsi, emva koko igesi yokuvuselela ifudunyezwa kwiqondo lokushisa lokuhlaziya i-180 ~ 260 ℃ ngokusebenzisa i-heater yokuvuselela, kwaye ingena ukusuka ezantsi kwe-adsorber kwi-hydrolyze kwaye ibhengeze i-adsorbed adsorbent. Igesi yokuhlaziya iphuma phezulu kwisomisi kwaye ingena kwisahluli segesi yokuhlaziya emva kokuba ipholile ngokupholisa ngokutsha. Emva kokwahlula i-liquid, ibuyela ekupheleni kwe-adsorber.

Emva kokudlula kwiyunithi, amanzi kwigesi yendalo eyomileyo ngu ≤ 1ppm.

Isixhobo esiphambili yinqaba ye-adsorption, i-heater yokuvuselela, i-cooler yegesi yokuhlaziya kunye ne-regeneration gas separator.
