Inkcazo yenkqubo ye-iron oxide yokususa igesi ye-asidi kwigesi yendalo
Ukususwa kwesulfurization
Kukho iindlela ezimbini eziphambili zokususa i-sulfurization yegesi yendalo: ukususwa kwe-sulfurization eyomileyo kwaye ukususwa kwesulfurization emanzi.
I inkqubo ye-amine iyasebenza xa igesi yendalo inomlinganiselo omncinci we-H2S kunye nomlinganiselo ophezulu we-CO2/H2S, kodwa umxholo we-CO2 awuphezulu kakhulu kwaye awufuni ukususwa kwe-CO2 enzulu. Le ndlela ingazisusa ngempumelelo zombini i-H2S kunye ne-CO2 ngaxeshanye.
Indlela yokuhluza i-molecular isetyenziswa kakhulu kwizicelo ezifuna ukuchaneka okuphezulu kokususa i-sulfurization okanye amazinga aphantsi okuhamba kwamanzi.
Apha sazisa inkqubo entsha ye-Iron Oxide
Inkcazo yeNkqubo ye-Iron Oxide
Esi siphakamiso samkela iinqaba ezimbini ezisebenza ngaxeshanye, zisebenza njengenkxaso yomnye nomnye.
Okokuqala, sebenzisa i-desulfurization tower A. Emva kokuba isebenze ixesha elithile, ukuba iziphumo zovavanyo zesampulu 2 zisondele kwixabiso loyilo, oko kuthetha ukuba ukupakisha kwe-tower kugcwele kwaye kulahlekelwe ngumthamo wako wokususa i-sulfurization, kwaye kufuneka kutshintshwe. Xa utshintsha, qala uvule ivalvu 3 kunye nevalvu 4, uze uvale ivalvu 2 kunye nevalvu 1, uze ucoce i-desulfurization tower A nge-nitrogen de uvavanyo lwegesi lufaneleke, uze uvule i-port yokucoca kunye ne-port yokungenisa umoya ukuze uvuselele ukupakisha. Emva kokuba ukuhlaziya kugqityiwe, vula i-manhole kunye nomngxuma wokukhupha ukuze utshintshe ukupakisha. Ngeli xesha, igesi idlula kwi-desulfurization tower B kwaye ifezekise injongo yokususa i-sulfurization.
Xa inqaba yokususa isalfurization B igcwele, vula ivalvu 1 kunye nevalvu 2, uze uvale ivalvu 3 kunye nevalvu 4, uze ucoce inqaba yokususa isalfurization B ngenitrogen ide ivavanyelwe igesi ukuba ifanelekile na, uze uvule izibuko lokucoca kunye nezibuko lokungenisa umoya ukuze uphinde upakishe, kwaye emva kokuba uhlaziyo lugqityiwe, vula imingxuma kunye nezibuko lokukhupha umoya ukuze utshintshe upakisho. Ngeli xesha, igesi idlula kwinqaba yokususa isalfurization A ukuze kufezekiswe injongo yokususa isalfurization.
I-feed gas sampling nozzle inikezelwa kwindawo yokungena kunye ne-outlet yenqaba nganye ukuze isampuliwe kwaye ivavanywe.
Umsebenzi wokuhlaziya i-desulfurizer uqala ngokusebenzisa igesi engasebenziyo ukutshintsha izinto zegesi ezinokutsha zibe ngaphantsi komda wokuqhuma. Ngexesha lokuhlaziya, umoya ungeniswa usuka ezantsi kwenqaba. Isantya somoya kufuneka sibe phantsi ekuqaleni kokuhlaziya. Ubushushu kwinqaba kufuneka bulawulwe ngokungqongqo ngaphantsi kwe-90 ℃. Ukuba budlula i-90 ℃, ukungeniswa komoya kunokuyekiswa. Xa ubushushu buhla ngaphantsi kwe-90 ℃, ukungeniswa komoya kunokuqhubeka nokungeniswa ukuze kuhlaziywe. Xa ubushushu bebhedi bungasanyuki kwaye umxholo weoksijini kwindawo yokungena kunye neyokuphuma ulingana, ukuhlaziywa kunokupheliswa. Xa kutshintshwa i-desulfurizer, isango lokukhupha elisezantsi kwenqaba linokuvulwa ukuze kukhululwe i-desulfurizer. Ngenxa yezizathu zokhuseleko, ukutshiza ngamanzi kufuneka kusetyenziswe ngokufanelekileyo ukupholisa.
Iimfuno zezinto eziphathekayo: Umzimba oyintloko wenqaba yokukhupha i-sulfurization wenziwe ngezinto ezilwa nokugqwala ze-Q345R.
