Izindlela Ezingcono Kakhulu Zokuhlanza I-Sodium Hydrosulfide Ngokuphumelelayo

Background

Embonini yamakhemikhali kaphethiloli, izindawo zokucwenga zivame ukukhiqiza amagesi ane-asidi ngesikhathi sokucutshungulwa kwemisebenzi efana nokuhluzwa kwe-vacuum kanye nokuqhekeka kwe-catalytic. Lawa magesi ane-asidi ngokuvamile aqukethe i-hydrogen sulfide engu-85%-95%, 3%-10% I-Carbon i-dioxide, amagesi e-organic angu-2%-5%, kanye nezinye izingxenye ezingu-0.5%-3%. Izindawo zokuhlanza ezincane neziphakathi zivame ukusebenzisa isisombululo se-caustic soda esingu-30% ukuze zimunce amagesi ane-asidi akhiqizwa ngesikhathi sokuhluzwa. I-caustic soda isabela ne-hydrogen sulfide ukuze yakheke I-Sodium Hydrosulfide. Lapho ukuhlushwa kwe-sodium hydrosulfide esixazululweni kufinyelela ku-30%, isisombululo siphinde sigxilwe. Ngemuva kokuphelelwa amandla kwamanzi nokugxila, okuqukethwe kwe-sodium hydrosulfide esixazululweni kungafinyelela ku-70%, bese i-sodium hydrosulfide icutshungulwa ibe yizingcezu.

Kodwa-ke, ukuba khona kwe-carbon dioxide emagesi ane-asidi kudala ukungcola kwe-sodium carbonate ngesikhathi sokwelashwa, okuthinta ukuhlanzeka komkhiqizo we-sodium hydrosulfide. Ukwengeza, ukusebenzisa isisiki esivulekile sokusika ukusika i-sodium hydrosulfide encibilikisiwe kungaholela ekuphenduleni kwe-oxidation nomoya-mpilo emoyeni, kukhiqize i-thiosulfate, evame ukuwohloka futhi okunzima ukuyigcina. Ukusika okuvulekile nakho kuvame ukukhulula amagesi acasulayo, kungcolise indawo yokukhiqiza.

Indlela Yokusebenza

1. Ukuhlukaniswa kwe-Centrifugal:

Dlulisa isixazululo esigxilisiwe se-sodium hydrosulfide ukusuka ethangini lokuhlushwa uye ku-scrifuge eyisikulufu esivundlile ukuze kuhlukaniswe, uthole usawoti ocwebezelayo kanye ne-monohydrate monohydrate sodium hydrosulfide encibilikisiwe.

2. I-Vacuum Insulation kanye Nokupholisa:

Thumela i-monohydrate sodium hydrosulfide encibilikisiwe, ngemva kokuhlukaniswa kukasawoti ocwebezelayo, ethangini lokufakwa kwe-vacuum ukuze lifudumale. Bese, uyipompa ku-vacuum paddle cooler ukuze uphole futhi uqiniswe ube amashidi amancane.

3. Ukufaka izikhwama okuzenzakalelayo:

Amashidi e-sodium hydrosulfide akhishwa nge-valve yenkanyezi emshinini wokupakisha ozenzakalelayo ukuze upakishwe.

Ngaphezu kwalokho, indlela yokuhlanza i-sodium hydrosulfide ihlanganisa lezi zinyathelo ezilandelayo:

1. Dlulisa isixazululo esigxilisiwe se-sodium hydrosulfide ukusuka ethangini lokuhlushwa uye ku-centrifuge yesikulufu esivundlile ukuze sihlukanise, uthole usawoti ocwebezelayo kanye ne-monohydrate monohydrate sodium hydrosulfide encibilikisiwe.

2. Thumela usawoti ocwebezelayo otholwe ku-centrifugation uyomisa ukomisa, lapho uqala ukuphelelwa amanzi emzimbeni engxenyeni yokushisa engaphezulu kwesomisi, bese ungena esigabeni sokupholisa sengqimba engezansi ukuze uphole ngaphambi kokuba uqoqwe njenge-ejenti yokwelapha amanzi ukuze usetshenziswe kamuva.

3. I-monohydrate sodium hydrosulfide encibilikisiwe, ngemva kokuhlukaniswa kukasawoti ocwebezelayo, ithunyelwa ku-vacuum insulation tank ukuze kushiswe. Ibe iphonswa ku-vacuum paddle cooler ukuze iphole futhi iqiniswe ibe amashidi amancane.

4. Amashidi e-sodium hydrosulfide akhishwa nge-valve yenkanyezi emshinini wokupakisha ozenzakalelayo ukuze upakishwe.

5. Isigaba segesi esikhishwe ku-vacuum insulation tank kanye ne-vacuum paddle cooler siphathwa ngesistimu yokuhlanza igesi engcolile.

Isiphetho

Le ndlela iqala ngokuhlukanisa usawoti ocwebezelayo oxubile, njenge-sodium carbonate, nesisombululo esigxilile se-sodium hydrosulfide. Bese, i-molten monohydrate sodium hydrosulfide iqiniswa ngokuqondile ibe amashidi amancane kusetshenziswa i-vacuum paddle cooler. Ekugcineni, umkhiqizo upakishwa kusetshenziswa umshini ozenzakalelayo wokufaka izikhwama. Ukuhlushwa kokungcola kwe-sodium carbonate emkhiqizweni kuncishisiwe kusuka ku-2.4% kuya ku-0.3%. Inqubo yokupholisa yenziwa endaweni yengcindezi engemihle, enciphisa amathuba okuthi i-sodium hydrosulfide ihlangane nomoya futhi ingene kwi-oxidation, ivimbele ngempumelelo ukuwohloka komkhiqizo. Ukusetshenziswa kwesistimu evalwe ngokugcwele yokuhlanzwa kwe-sodium hydrosulfide kuqinisekisa ukuthi awekho amagesi acasulayo akhishwa phakathi nenqubo, ukugwema ukungcoliswa kwesibili kwemvelo. Amashidi e-sodium hydrosulfide afakwe izikhwama ngokuqondile, avimbela ukungcola ngesikhathi sokugcinwa. Ukwengeza, lokhu okusunguliwe kuhlanganisa indlela elula, kudinga okokusebenza okuncane, futhi kunezindleko eziphansi.
