Wet Scrubbers

Product Details:

Shimi Research Center Private Limited is a leading Packed Bed Scrubber manufacturer in India. Packed Bed Scrubbers are highly effective for removing soluble chemicals, fumes, and odors. We supply packed bed scrubbers in different parts of the world which are manufactured from export quality raw materials. At present we are one of the leading exporters of Packed Bed Scrubbers to South Africa and Middle East countries such as UAE and Saudi Arabia. Our engineering staff is capable of providing you with equipment integrating all aspects of your air pollution control requirements.

The Packed Bed Scrubber, or Packed Tower, is designed to improve contact between two phases in a chemical process by having one or more beds of solid packing material. Packing offers the advantage of a lower pressure drop across the tower, which is beneficial while operating under vacuum. Differently shaped packing materials have different surface areas, which creates a void space between the packing that allows for absorption of gases and vapors. The combination of packing material, packing design, depth of packing, bed velocity, and the scrubbing liquid chemistry and quantity, are the factors that affect packing performance.

The purpose of a packed bed is typically to remove gaseous or vaporous pollutants from an air stream. To achieve this, the tower is filled with specially designed packing material, which are arranged or stacked to a specified depth (creating a stacked packed column). In the tower, the scrubbing liquids tend to wet the surface of the packing and when the polluted gas stream pass across this wetted surface, the pollutants get absorbed following the chemical reaction. Some vapors can be simply removed by condensation through the cooling effect of the circulating liquid. The cleaned air is then discharged to the atmosphere and the contaminated scrubbing liquor is either disposed of in an approved manner or chemically treated and recycled. In some cases, the collected contaminants can be recovered and reused in the original or other processes.

The packed bed (or packed tower) scrubber is capable of only limited particulate matter control, and they easily choke with high solids loadings in the gas stream.

The main contaminants that it can remove are:

• Acid gases (H2S, HCl, HF)
• HCN
• NH3
• Cl2, F2
• NOx and SOx
• Formaldehyde

Applications:

• Chemical production
• Fertilizer production and processing
• Pulp and paper
• Petrochemical
• Pharmaceutical
• Food and beverage
• Electronics (chip manufacturing)
• Odor control
• Incinerator systems

Shimi Research Center Private Limited is a leading Venturi Scrubber manufacturer in India. Venturi Scrubber effectively reduces the contamination level of flue gas. Our Venturi scrubbers are widely used as a Flue Gas Desulphurization, FGD unit and the areas where the flue gas is highly contain dust particles and corrosive fumes. For the superlative product quality, we manufacture Venturi scrubbers with best quality raw materials. We supply Venturi scrubbers in different parts of the world. At present we are one of the leading exporters of Venturi Scrubbers to South Africa and Middle East countries such as UAE and Saudi Arabia.

Venturi Scrubbers have the highest particle collection efficiency of any wet scrubbing system which can reduce the contamination level of flue gas up to 99%. A Venturi scrubber consists of three sections: a converging section, a throat section, and a diverging section. Their open construction enables them to remove most particles without plugging or scalding. The inlet gas stream enters the converging section and, as the area decreases, gas velocity increases. Particle and gas removal occur in the throat section as the inlet gas stream mixes with the fog of tiny liquid droplets. The ability of Venturis to handle large inlet volumes at high temperatures makes them very attractive to many industries. For use in industries with high corrosive gas emissions, high-grade stainless steel such as SS-316 is used for the construction of a Venturi scrubber. Our system capacity ranges from 1000 CMH to 200000 CMH. The running cost of our systems is depended on the application and capacity. As a rule of thumb, treatment of 1.0 CMH contaminated flue gas Venturi scrubber requires 1.5 - 2.0 KW electricity.

Venturi scrubbers meet the unique needs:

• for particulate removal.
• for variable exhaust volumes.
• for gas absorption and particulate removal
• for course particulate removal.

Features:

• High cleaning efficiency is high
• High pollution load acceptance
• Pollutants can be removed from scrubbing liquid using water recycling units
• Works well even at high temperatures

Shimi Research Center Private Limited is a leading Boiler Flue Gas CO2 Recovery Scrubber Manufacturer in India. We manufacture export quality Boiler Flue Gas CO2 Recovery Scrubber with superlative raw materials. This is a multistage medium to high pressure scrubbing technology where the impurities in the form of particulate matter (dust) and SOx are removed effectively from gas streams ensuring clean source of CO2 at low temperature for either further purification or direct use in reactor for the preparation of precipitated calcium carbonate, the main filler used in paper industries. Because of our eminent product quality we are continuously exporting Boiler Flue Gas CO2 Recovery Scrubber in different parts of the world. At present we are one of the leading exporters of Boiler Flue Gas CO2 Recovery Scrubber in Middle East and South Africa.

In the initial stage of scrubbing, the particulate matter is removed from the gas stream followed by the SOx. The scrubbing media has high affinity for SOx without effecting the concentration of CO2 in the gas stream.

 

The water recycling is an optional part of the system and is used when the gas stream contains high particulate matter concentration or temperature. The system will remove the impurities from the contaminated water and ensure clean recycled media for reuse. Boiler Flue Gas CO2 Recovery Scrubber are available in SS-316L and PP for high and low temperature applications respectively.
