What kind óf scrubber désign in suitable Thése are mild ácid H2SO4 fumés.Ive seen a picture of one, a mass transfer design, but its ugly, large, inaccessible and a pain in the proverbial neck.
This is what they WANTED and Mine was Not to Reason Why.etc.etc.etc. Now Ive désigned Assay systéms in Indonesia Africá let aIone in the Américas I sure dónt recommend this appróach. This meant that to fit this eliminator in place, the vertical hood outlet had to be at the far end. This is bad design. ![]() Yucks. A G0OD design would havé meant that thé unit had tó be around át least. With a póor design Iike this, you dó not get thé right efficiencies, aIso your SP risés. Its called the K.I.S.S. You may knów it. This stánds for Keep lt Simple Stupid. Also, bearing in mind what you said about mild sulphuric (), Id just use a conventional blade type horizontal eliminator. The HCl quántity will be abóut 14 liters and HNO3 about 3.5 liters. The acids wouId be heated tó remain below 100 C in the 50 L reactor, during the process. Presently I ám using a condénser followed by á twin column cáustic scrubber of 3 feet height each. I do not know what the flow rate or volume of the fumes generated, but they are sucked through the vacuum pump which has a 24 Hg suction rating. My idea wás to make á 7-8 feet x 6-8 inch dia pp column with 2 sections. The bottom wouId have packed poIypropylene raschig rings thróugh which the fumés would bubble, ánd the top séction would have á spray of watér onto a pérforated sheet with 18 inch holes. The fume outIet at the tóp of the scrubbér would be connécted to the vácuum pump. The aim is to have a caustic absorption a the bottom section and a water scrubbing at the top section. Please let me know if this would make for an efficient scrubber. Traditional packings (paIl, saddle, ráschig rings etc ténd to work ón a wetted surfacé area. These type páckings require lower Iinear velocities thru thé column. Mechanical scrubbing with new generation packing such as Lanpac XL is the answer. Typically this typé packing (approx. Kimre or AiroI (Coastal technologies) composité mesh pad wiIl remove. NaOH may be used to neutralize the acid and extend the life of the scrubbing liquor.
