3.2.2.2 Iyunithi yokukhipha kanye nokomisa igesi yegesi

1）Incazelo yenqubo

Igesi yemvelo evela kuyunithi yegesi yokuphakelayo yokuqeda acid acid ingena kukhabhoni efakwe isibabule efakwe kusebenze. I-Mercury ihlangana nesulfure kukhabhoni ecushiwe efakwe kwisulfure ukuze ikhiqize i-mercury sulfide, ekhangiswa kukhabhoni ecushiwe, ukuze kufezwe inhloso yokususwa kwe-mercury. Okuqukethwe kwe-mercury kwegesi yemvelo evela kusikhiphi se-mercury kungaphansi kuka-0.01μg/Nm³.

Isikhiphi esisodwa se-mercury sizosethwa, futhi ikhabhoni efakwe isibabule efakwe ku-activated izoshintshwa ngokwemibandela yokuhlolwa.

Igesi yemvelo ngemva kokususwa kwe-mercury ingena endaweni yokomisa. Iyunithi isebenzisa ubuchwepheshe be-adsorption bezinga lokushisa lokuhlukanisa nokuhlanza igesi. Ubuchwepheshe be-adsorption bezinga lokushisa busekelwe ekukhangiseni ngokomzimba kwamangqamuzana egesi endaweni yangaphakathi ye-adsorbent (izinto eziqinile ezimbotshana), futhi busebenzisa izici amandla we-adsorption we-adsorbent wegesi aguqukayo ngezinga lokushisa elihlukile le-adsorption kanye nokucindezela, Ngaphansi kwesimo sokuthi i-adsorbent ikhetha ngokukhetha ingxubevange yezingxenye eziphansi zegesi nezinga eliphezulu lokushisa. ukucindezela, futhi izingxenye ezingenazo i-adsorbed zigeleza kungqimba lwe-adsorber. Lezi zingxenye ze-adsorbed zi-desorbed kumazinga okushisa aphezulu kanye nokucindezela okuphansi kwezinga lokushisa eliphansi elilandelayo kanye ne-high-pressure adsorption. Imibhoshongo eminingi ye-adsorption ingasetshenziswa ukufeza inhloso yokuhlukaniswa kwegesi okuqhubekayo.

Iyunithi yokomisa igesi ephakelayo kanye neyunithi yokususa i-hydrocarbon esindayo ifakwe izikhangisi ezintathu zokushintshwa komsebenzi, eyodwa eyokukhangisa, enye eyokuvunguza okubandayo neyokuvuselela ukushisisa.

Igesi ephakelayo evela kumbhoshongo we-demercuration ingena phezulu kwe-adsorber, isuse amanzi nge-molecular sieve adsorption, iphuma ngaphansi kwe-adsorber, futhi ingena kuyunithi yokukhipha igesi enzima ye-hydrocarbon ngemva kokuphelelwa amanzi emzimbeni.

Iyunithi yokomisa igesi yokuphakelayo isebenzisa inani elincane legesi yokuphakelayo njengendawo yokuphephetha okubandayo nokuvuselela kabusha. Ngemuva kokuthi igesi yokukhiqiza kabusha ishiya umbhoshongo we-adsorption, ibuyela ekungeneni kombhoshongo wokomisa esimweni se-adsorption ngemuva kokupholisa nokuhlukana.

Igesi yokuvuselela kuqala idlula ku-adsorber epholile isuka phezulu iye phansi, bese igesi yokuvuselela ishiselwa ekushiseni kokuvuselela okungu-180 ~ 260 ℃ nge-heater yokuvuselela, bese ingena isuka phansi kwe-adsorber ukuze i-hydrolyze futhi idsorbe i-adsorbed adsorbent. Igesi yokuvuselela iphuma phezulu kwesomiso futhi ingena kusihlukanisi segesi sokuvuselela ngemva kokupholiswa yi-cooler yokuvuselela. Ngemva kokuhlukanisa uketshezi, lubuyela ekugcineni kwe-adsorber.

Ngemva kokudlula kuyunithi, amanzi kugesi yemvelo eyomile angu-≤ 1ppm.

Imishini eyinhloko i-adsorption tower, i-heater yokuvuselela kabusha, i-regeneration gas cooler kanye nesihlukanisi segesi sokuvuselela.

3.2.2.3 Iyunithi yokuhlunga igesi yesiphakeli

1）Incazelo yenqubo

Iyunithi yokuhlunga ifakwe isihlungi, esingashintshwa ngokuya ngedatha yokumelana ukuze kuzuzwe inhloso yokuhlunga isisefo samangqamuzana nothuli lwekhabhoni olucushiwe.

Ngemuva kokususwa kothuli, izinhlayiya zothuli kugesi ophakelayo zingaphansi kuka-10μm.

Imishini eyinhloko isihlungi sothuli.
