Fume Scrubbing/Exhaust System

Several industries generate toxic fumes, vapours along with dust during their manufacturing process. These processes need an exhaust system from three aspect.

Fume Scrubbing Unit
  • To ensure the operators health and safety by removing the hazardous fumes from the working area
  • To avoid pollution problems
  • Sturdy construction
  • To increase the product quality removing fumes from the process


The unwanted fumes generated during the process will be exhausted through properly designed suction hood with required capture velocity. The exhaust air will be routed through a Packed bed scrubber / Plate scrubber / Venturi scrubber to eliminate hazardous fumes, odour & dust in the exhaust air & clean air will be exhausted to ambient.


Fume scrubbing / Extraction system comprises of following

Fume Scrubbing
  • LEVs / Suction hood
  • Ducting
  • Packed bed scrubber / Plate scrubber / Venturi scrubber
  • Pump to handle scrubbing liquid
  • Blowers
  • Chimney

BATS offer an excellent, custom built, efficient fume scrubber system to tackle fumes, vapours, dust generated in many process industries. The system will be designed such way that the hazardous fume will be exhausted from the point of generation itself by providing Local Exhaust Vents ( LEVs). The system design, material of construction, system capacity all are related to the type of industry, type of fumes, vapour & dust, location of generation. BATS offers fume scrubbing system compliance with standard pollution control norms. This system is made to order hence basic design data need to be furnished to design, install the scrubber systems.

Dust Extraction/Collection System

Recovery of particulate matter from exhaust gas is vital for any industry from three aspect

  • To ensure the operators health and safety by removing the hazardous fumes from the working area
  • To avoid pollution problems
  • Sturdy construction
  • To increase the product quality removing fumes from the process


Dust collection systems is used in many processes to either recover valuable granular solid or powder from process streams, or to remove granular solid pollutants from exhaust gases prior to venting to the atmosphere. Dust collection is an online process for collecting any process-generated dust from the source point on a continuous basis. Dust collectors may be of single unit construction, or a collection of devices used to separate particulate matter from the process air. They are often used as an air pollution control device to maintain or improve air quality.


The dust generation in manufacturing process directly effects the operator’s health, can contaminate the product which is being manufacturing can make highly uncomfortable for the people in & around the dust generating areas. BATS wish to offer a solution by incorporating dust control & extraction system & ensure a safe & pure zone for the occupants. This process involves exhaust blowers, exhaust air duct work and dust collection hoods to pick up dust particles at the point of generation. In several cases, the dust collected by the system from the point of generation is routed through a filter unit which collects the dust & pure air will be exhausted to the ambient to meet pollution control.


Dust collection / Extraction system comprises of following



Paint shop / Painting booth with exhaust ventilation system

BATS manufacture spray painting booth with the customized sizes. The exhaust system remove the paint fume laden air inside the painting zone.


BATS spray painting booths are available in two types.


1. Wet type


This type of spray painting booth will have water screen to scrub the exhaust fume laden air before dispersing to the atmosphere. This painting booth will have internal water sump, water screen plate, water re circulating system, rear side draft section with exhaust blowers and spray painting zone. If the paint booth has to be closed one, we provide make up fresh air system as optional.


2. Dry type


This type of spray painting booth will have filter media (paper / fabric) to eliminate the paint fume from the exhaust air. This paint booth will have filter section in the rear draft plenum.

We select the material of construction based on the MSDS of the paint.


We execute total paint shop project providing required paint booths, flash off zones, conveyor, baking oven and other required material handling systems.




Odor control systems

BATS is having highly experience and expertise in providing full-service custom-designed abatement solution for odour control. The innovative engineering concept minimizes the operating costs, enhances the efficiency and most importantly, solves your specific problem. We use the most effective method of Activated carbon adsorber in our odour control systems.


Activated Carbon


Activated carbon is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions. A variety activated carbon products is available exhibiting different characteristics depending upon the raw material and activation technique used in their production.


Activation refers to the increasing the adsorption properties of carbon. Raw materials such as coal and charcoal do have some adsorption capacity, but this is greatly enhanced by the activation process.


Activated carbon can be produced from carbonaceous source materials like nutshells, wood and coal. The raw material has a very large influence on the characteristics and performance activated carbon.


Surface Area of Activated Carbon


Activated carbon exhibits rapid adsorption kinetics or the highest volume of adsorbing porosity of any material known to mankind. It can have a surface of greater than 1000m²/g.


Adsorption by Activated Carbon


Adsorption may refer as the accumulation of atoms or molecules on the surface of the activated carbon. This process creates a film of the adsorbate (the molecules or atoms being accumulated) on the surface. It is mainly caused due to London Dispersion Forces, a type of Van der Waals Force that exists between molecules. The force acts in a similar way as gravitational forces between the planets.


In selecting an activated carbon, it is important to develop a clear understanding of both the adsorptive and physical characteristics of the material in order to optimize the performance capabilities.


Forms of Activated Carbon


There are two forms o activated carbon:

  • Granular Activated Carbon: The irregular shaped particle has a relatively larger particle size ranging from 0.2 to 5 mm. These carbons are preferred for both liquid and gas phase applications.
  • Pelleted Activated Carbon: These are extruded and cylindrical shaped activated carbon with diameters from 0.8 to 45 mm. They are mainly used for gas phase applications because of their low pressure drop, high mechanical strength and low dust content.

Using Activated Carbon


A high performance impregnated activated carbon pellet is used for the removal and containment of hydrogen sulphide, organic mercaptans (thiols) and certain organic sulphides from air. The granular carbon is installed in the fixed bed allowing the liquid to pass through the bed. Compounds required to be removed are retained on the activated carbon.


The activated carbon can be used till its exhaustion. It can be normally reactivated or replaced with the new carbon.


Design Information : The main factors in the design of an adsorption system are the carbon consumption (amount of carbon required to treat the liquid or gas) and the contact time (for a fixed flow rate, the contact time is directly proportional to the volume of carbon).


To recover activated carbon.


Regeneration of activated carbon has to be done by passing the LP steam. Direct steam should be passed at 100oC for approximately 20 minutes.  Steaming direction has to be in the opposite direction to the adsorption to prevent possible accumulation of polymerisable substances, and also to permit the shortest route for the desorbed contaminant.
