We also supply air pollution control equipment. We present with gas scrubbing solutions to industries like pharmaceutical, chemical & fine chemical, waste water & sewage, metallurgical, glass & ceramics and petrochemical industry. Our packed tower scrubbers are built according to the counter-flow principle. A packed tower consists of main sections like base section or sump which acts as a liquid reservoir for the column and is connected to the recirculation pump inlet, packed bed section throughout which gas absorption occurs and upper section which is made up of the liquid distributor to ensure even liquor distribution across the packing. Typical gases removed by these types of scrubber include hydrogen chloride, ammonia, oxides of nitrogen, sulphur dioxide, phosgene, chlorine, hydrogen sulphide, amines, bromine and nitric acid.
