Apstrakt

U ovom radu izvršen je proračun i dimenzionisanje dvostepenog skrubera sa pakovanim slojem za prečišćavanje otpadnog gasa iz hemijske industrije koji sadrži amonijak u koncen­traciji od 1400 mg m-3. Za proračun su korišćene osnovne jednačine materijalnog bilansa, ravnotežni podaci, kao i generalizovana korelacija za pad pritiska. Prilikom proračuna i analize različitih konfiguracija korišćen je Katmar softver koji koristi generalizovanu kore­laciju za pad pritiska za određivanje prečnika skrubera na osnovu dozvoljenog pada pritiska i udaljenosti od uslova plavljenja. Utvrđeno je da se optimalni rezultati postižu u dvoste­penom uređaju, korišćenjem sumporne kiseline (70 %) za hemisorpciju amonijaka. Kao punjenje u koloni odabrani su Palovi prstenovi dimenzije 50 mm izrađeni od polipro­pilena. U radu su analizirane kolone prečnika Dc = 2; 2,1 i 2,2 m. Sa aspekta protoka tečne faze prečnik kolone Dc = 2 m zadovoljava, a prema specifikaciji punjenja pad pritiska kroz ukupnu visinu sloja punjenja je oko 900 Pa. Utvrđeno je da se gradijent pritiska, a samim tim i ukupni pad pritiska u koloni smanjuje povećanjem prečnika kolone. Međutim, sa pove­ća­njem prečnika kolone raste minimalni protok tečne faze potreban za kvašenje punjenja, te se potreban protok tečne faze povećava. Uzimajući u obzir sve procesne parametre, kao i zah­tevanu efikasnost prečišćavanja otpadnog gasa, predložena je optimalna konfiguracija uređaja.
