Pharmaceutical facilities frequently have a number of batch
manufacturing reactors that during operation can generate noxious fumes such as HCl, HBr, NH3, and HF. The plants are faced with either having a small emission control unit at each reactor, or one large central emissions control unit with a maze of ductwork running to and from each source. The emission control units are usually scrubbers which are comprised of a noxious gas/chemically entrained liquid contactor, a collector tank, a pump, and a fan. In the case of the central emissions control unit a large fan must run continuously for potentially a small job. The cleaned(scrubbed) gas is usually sent to atmosphere meaning replacement air either heated or cooled must be sent into the building to keep it in pressure balance. D. R. Technology offers an alternative to the two options. This is a portable, light weight scrubber complete with tank, pump, contactor/s, and instruments. These are all mounted on a skid with casters so it can be moved from source to source. Only the vent rate from the source must be exhaust to the atmosphere. The unit can treat pure acid emissions by using an optional internal or external heat exchanger to use cooling water to take up exothermal heat of reaction and solution.
The unit can be constructed of highly acid and solvent resistant fiberglass resin such as Furan with fluorinated polymer media.
