Why Setup a Wet Scrubber System?

Black smoke emissions into the atmosphere from boiler flue-gas stacks are a common sight in rural Malaysia, where the majority of palm oil mills are located. The main pollutant of concern is the particulate matter present in the stack discharge that gives rise to suspended atmospheric particulate matter at ground level in the surrounding areas of the palm oil mills. This poses serious health concerns for the mill workers and residents who live or work in the neighborhoods surrounding the mills.

Thus, the government has enacted the Environment Quality (Clean Air) Regulations 2014, to enforce the compliance of maximum concentration limit values for selected air pollutants at the flue-gas stack discharge. Emission limits have been established to address various concerns about atmospheric pollution affecting both the human and natural environment. The prescribed maximum emission limit value for total particulate matter concentration is 150 mg/Nm3, and for smoke opacity is shade No. 2 on the Ringlemann Chart for boilers of capacities used at palm oil mills. However, the particle concentration limits in term of the particulate size classification are not specified. Maximum value is also prescribed to limit the concentration of gaseous pollutant of Carbon Monoxide to 1000 mg/Nm3.

A wet scrubbing system is integrated into existing mill boiler systems to collect particulates emitted. Very fine particulates in flue gasses can be scavenged similar to rainfall scavenging of dust particles in the atmosphere. Flue gas particulate content is reduced 90% from current acceptable levels and there is a noticeable reduction in black smoke emission.

System Features

Removes particles and reduces gases such as CO, CO₂, NOx and SOx effectively.

Environmentally friendly. No chemicals required for scrubbing.

No major maintenance or capital expenses even after 5 years.

Water recycling system which evaporates 5-10m³ of effluent water per hour.

High-efficiency stainless steel mist eliminators are placed in strategic positions to arrest water droplets and particles.

No dedicated personnel required for daily wet scrubber system upkeep.

Mist eliminators designed to have minimum back pressure to the boiler.

Filtration system for wet scrubber slurry cleaning, where the solid fly ash is constantly removed.

All wetted parts are of stainless steel SS304 material for corrosion resistance.

Inspection doors are provided at strategic points for cleaning and maintenance purposes.

Chimney, from base to 20ft height, is coated with high-temperature corrosion resistance coating for corrosion protection.
