GPT Wet scrubbers are highly efficient & effective in neutralizing toxic flue gas from all types of Boiler & Furnace emissions. Its high efficiency of spray nozzles, fine atomisation of water droplets together with good designing & engineering along with good aesthetics makes it a unique product. The Scrubbers are connected with a single Centrifugal Blower for efficient & optimum suction of the gases. Other customized solutions are also available based on various parameters viz. material thickness, material of construction (MS/SS-304/SS-316). We can offer Venturi, Packed bed, impingement & Spray tower type Scrubbers. Wet scrubber designs such as spray towers, venturis, plate towers, and packed beds can be used. Considering operational issues such as scale buildup, plugging, etc., industry adopt simple scrubbers such as spray towers. However, these spray towers however, require a higher liquid-to gas ratio requirement for equivalent SO2 removal than other absorber designs. Scrubbing reagents: Limestone and sodium hydroxide can be used as alkaline scrubbing reagents. Range starts from 5000 m3/hr. to 100000 m3/hr.

SO2 Absorption: SO2 is absorbed when the flue gas is intercepted by tiny droplets of slurry in the absorber. Water in the slurry captures the SO2, changes it into a liquid sulphur-based acid. SO2 + H2O → H2SO3 H2SO3 → H+ + HSO3 - Limestone Dissolution: CaCO3 + H2O → Ca2+ + HCO3 - + OH Oxidation: Through the process of oxidation, sulphite (SO3) is converted to sulphate (SO4). The sulphate byproduct, when combined with the calcium, forms calcium sulphate. HSO3 + O2 → H+ + SO4 2- Precipitation: Precipitation is the process by which a substance separates from a solution due to a chemical change in the solution. The absorbed SO2 reacts with the dissolved limestone to form new products i.e. calcium sulphate (CaSO4), or gypsum Ca2+ + SO4 2- + 2H2O → CaSO4*2H2O Gypsum

GPT manufactures high quality Scrubber for Injection Moulding Machine to remove the toxicity in the fumes. Material of construction can be MS, SS in any grade and thickness.

High Energy Scrubbers (Venturi Scrubbers)
Venturi scrubbers are widely used for various applications. A Venturi wet scrubber system section always has uniform wet surfaces which avoids and eliminates wet and dry line build-up problems. Venturi scrubber has the following main components:

Ventury

Throat

Flooded elbow

Separator

Mist eliminator

Throat can have different designed constructions like fixed, butterfly type or double flap type. Heavy dust laden gases are passed through the venturi unit in vertical direction. At the venturi section, scrubbing liquid is injected through tangential pipes and spray headers. This ensures complete coverage on venturi and throat area. The throat is operated in a manner to obtain the suitable pressure drop for getting the maximum collection efficiency. The scrubbed gases are then drawn into a cyclonic separator through a 90-degree flooded elbow. At the cyclonic separator gases and liquid droplets separation occurs. The slurry is discharged through the bottom cyclonic separator and cleaned, and scrubbed gases are vented out through mist eliminator by eliminating carry over liquid particles.High Energy Scrubbers (Venturi Scrubbers)
