Iyunithi yokususa i-hydrocarbon enzima yegesi yendalo kunye neyunithi yokususa i-mercury zizixhobo ezimbini eziqhelekileyo kwi ukucubungula igesi yendalo.
Iyunithi yokususa i-hydrocarbon enzima yegesi yokutya
1（Umsebenzi wenkqubo
Iihydrocarbons ezinzima kunye neehydrocarbons ezinuka kamnandi kwigesi yendalo nazo ziya kuqina kubushushu obuphantsi, ngoko ke kufuneka zisuswe. Le yunithi isebenzisa indlela yokufunxa ikhabhoni esebenzayo ukususa iihydrocarbons ezinzima kunye neehydrocarbons ezinuka kamnandi.
Kule yunithi, kusetyenziswa iinqaba ezimbini ezifanayo zokufunxa iihydrocarbons ezinzima kunye neehydrocarbons ezinuka kamnandi. Indlela ye-TSA isetyenziselwa ukuhlalutya iihydrocarbons ezinzima kunye neehydrocarbons ezinuka kamnandi kwikhabhoni esebenzayo. Kwangaxeshanye, indlela yokufunxa isetyenziselwa ukufunxa nokwahlula iihydrocarbons ezinzima kunye neehydrocarbons ezinuka kamnandi ezisuswe kwi-adsorbent.

Ioyile yokudlulisa ubushushu evuselelayo evela kumthombo wobushushu obuphezulu
Umxholo we-hydrocarbon enzima kunye ne-aromatic hydrocarbon kwigesi ecociweyo kufuneka ube yi-≤ 10ppm ngokulandelanayo
3） Ububanzi bokuziqhelanisa
Uluhlu lolawulo lomthwalo yi-50 ~ 110%.
4） Inkcazo yokuhamba kwenkqubo
Igesi yendalo evela kwi iyunithi yokomisa igesi yokondla Okokuqala ingena isuka phezulu kwinqaba yokususa iihydrocarbon ezinzima ngevalvu yokulawula uxinzelelo oluhlukeneyo. Emva kokususa ihydrocarbon enzima nge-adsorption ye-activated carbon bed, iphuma ezantsi kwinqaba yokususa iihydrocarbon ezinzima. Emva kokususa ihydrocarbon enzima, umxholo we-aromatic hydrocarbon kwigesi yendalo yi-≤ 10ppmv, ize ingene kwiyunithi yokususa imercury kunye nokucoca uthuli.
Iyunithi yokususa iihydrocarbon ezinzima ixhotyiswe ngeetowuru ezimbini zokususa iihydrocarbon ezinzima. Ngaphakathi komjikelo othile wokufunxa, enye ikwimeko yokufunxa ukuze isuse iihydrocarbon ezinzima kwigesi yokutya, kwaye eyesibini ikwimeko yokuvuselela (ukufudumeza nokuvuthela kubanda) ukuze isuse iihydrocarbon ezinuka kamnandi kwikhabhoni esebenzayo. Xa itowuru yokususa iihydrocarbon ezinzima kwimeko yokufunxa igcwele, tshintshela kwitowuru yokususa iihydrocarbon ezinzima egqibezela ukuvuselelwa. Itowuru yokususa iihydrocarbon ezinzima ezigcwele ilandelwa ngumjikelo wokuvuselela ukufudumala uze emva koko uphole.
Igesi yokuvuselela ifunyanwa ngaphambili kwevalvu yokulawula uxinzelelo oluhlukeneyo. Igesi yokuvuselela ingena kwisithando sokufudumala segesi yokuvuselela kwaye ifudunyezwa ukuya kuma-220 ~ 280 ℃. Igesi eshushu neyomileyo isusa iihydrocarbons ezinuka kamnandi kwikhabhoni esebenzayo ukusuka phezulu ukuya ezantsi ngenqaba yokususa iihydrocarbons ezisindayo. Igesi yokuvuselela equlethe iihydrocarbons ezinuka kamnandi kwinqaba yokususa iihydrocarbons ezisindayo kwimeko yokuvuselela (yokufudumeza) ingena kwifriji yegesi yokuvuselela ukuze iphole rhoqo, ize yahlule iihydrocarbons ezinuka kamnandi ezingaphakathi kwi-separator, kwaye ulwelo oluvaliweyo lungena kwi-separator yegesi yamafutha.
Igesi evela phezulu kwesahluli segesi yokuvuselela ingena kwinqaba yokufunxa ikwimeko yokufunxa kunye negesi yendalo ephumayo ngasemva kwevalvu yokulawula uxinzelelo oluhlukeneyo.
Igesi yokutyaiyunithi yokususa kunye nokucoca i-mercury
1） Inkcazo yenkqubo
Igesi yendalo evela kwiyunithi yokomisa igesi yokutya kunye neyokususa i-hydrocarbon enzima ingena kwi-sulfur impregnated adsorber ye-activated carbon efakwe kwi-sulfur. I-Mercury isabela kunye ne-sulfur kwi-sulfur impregnated activated carbon ukuvelisa i-mercury sulfide, efakwe kwi-activated carbon, ukuze kufezekiswe injongo yokususa i-mercury. Umxholo we-mercury wegesi yendalo evela kwi-mercury remover ungaphantsi kwe-0.01μg/Nm3。
Kusetwa i-mercury remover enye, kwaye i-activated carbon efakwe kwi-sulfur itshintshwa ngokwendlela efunyenwe ngayo.
Iyunithi yesihluzo ixhotyiswe ngesihluzo, esinokutshintshwa ngokwedatha yokuxhathisa ukufezekisa injongo yokucoca isihluzo semolekyuli kunye nothuli lwekhabhoni olusebenzayo.
Emva kokususwa kothuli, amasuntswana othuli kwigesi yokutya angaphantsi kwe-10μm.
Izixhobo eziphambili sisihluzi se-mercury kunye nesihluzi sothuli.
