PECMA Ventury scrubber comprises a contact section called a venture section in combination with a separator section. Dust laden gas is led into the venture section where it passes through a water screen at the venture throat at high velocity. This results in a through mixing of water droplets and dust particles which agglomerate to form large particles which are then collected from the gas in the separator section. The water supply units and the atomizing system permit recirculation of water with high dust content. Ventury Scrubbers have successfully been installed for cleaning particulate matter from exhaust gas streams of foundries crushing plant, electric are furnaces, basic oxygen furnaces and urea prilling towers, phosphatic fertilizer plants and other chemical and petrochemical industries.

PECMA vertical packed bed scrubbers are equipped with a very efficient contact zone, a gas distribution section, a liquid distribution system and a mist eliminator. The specially designed gas distribution section ensures even distribution of gases over the entire cross-section of the tower.

The highly efficient liquid distribution system combined with an even gas flow ensures a very intimate gas-liquid contact. The mist eliminator section effectively removes the carry over of liquid droplets from the contact zone. Packed Bed Scrubbers offer very high collection efficiencies at comparatively lower pressure drops. The effluent liquid can be recycled in this process.

Packed Bed Scrubbers are used to remove corrosive fumes and toxic gases like sulphur dioxide , chlorine hydrochloric, hydrofluoric , hydrogen sulphide, phosphatic acid , cyanides ammonia and other organic and inorganic gases etc.

Outlet Emissions are Even Less Then 1 Ppm. Can Be Achieved.

Desulphurization
This system uses the principal of gas and solid chemisorption technique for the removal of toxic gases like hydrofluoric acid, So2 etc. The system usually consists of gas-solid reactor followed by a fabric filter for collecting reaction products. This system is specially suitable for removal of particulate and gaseous fluorides from pot gases in an aluminum smelter and also for cleaning exhaust gases from refuse/chemical incinerators.

Industrial Ventilation and Clean room systems equipments mainly Air shower, Air washer, Centrifugal fans.

Pecma impingement scrubbers are available in different arrangements like spray tower. The air may be forced to impinge on a series of baffles. These are gain low energy category scrubbers and have relatively low degree of particulate removal. The efficiency will range from 90 to 95 % for 10 microns particulars. Water consumption will range from 35 to 70 liters of liquid for per1000 M3 of gas.
