Typical control measures used in pharmaceutical industry to reduce VOCs (including odors) are condensation, absorption (spray towers, venturi scrubbers, packed columns, and plate columns), adsorption (using activated carbon beds), thermal destruction (flares, boilers and process heaters, thermal incinerators, and catalytic incinerators), and vapor containment. Water- or brine-cooled condensers are the most common control devices, with carbon adsorbers in occasional use. Where the main objective is not solvent reuse but is the control of an odorons or toxic vapor, scrubbers or incinerators are used [86]. Typical spray dryer systems equipped with thermal and catalytic incinerators are shown in Figure 53.7. 

Ammoniation of brine. There are conflicting problems in this part of the process. A concentration of ammonia in brine is necessary to obtain the maximum yield of sodium bicarbonate, but if it is too concentrated, salt will precipitate out. Ammonia is expensive and the brine is allowed to pass through a number of ammonia-containing residual gas streams in countercurrent flow before passing into the main ammonia absorption tower. The process is exothermic and the resulting solution must be cooled. Some valuable dilution occurs from the water vapour contained in the ammoniacal gas streams.
