On March 2019, Rompin Palm Oil Mill (RPOM) had embarked and commissioned a Double Field Electrostatic Precipitators (ESP) as part of its environmental quality (clean air) project. The RM2.5 million project would effectively limit the total particulate emission from the palm oil mill boiler chimneys from 400 mg/Nm3 to under 150 mg/Nm3.
An electrostatic precipitator (ESP) is a particle control device that uses electrical forces to move the particles out of the flowing gas stream and onto collector plates. The particles are given an electrical charge by forcing them to pass through a corona, a region in which gaseous ions flow.

Electrostatic precipitator technology is the preferred PM removal technology in the power industry because of its advantages of large amount of flue gas, high PM removal efficiency, low equipment resistance, simple and reliable use, low operation and maintenance cost, and no secondary pollution [7–10].
Electrostatic Precipitator an overview ScienceDirect. Dilip Kumar, Deepak Kumar, in Sustainable Management of Coal Preparation, 2018. 12.4.7 Electrostatic Precipitators. ESPs are particulate control devices that use electrical forces to move particles from the air stream to the collection plates.
The electrostatic precipitator recovers the fly ash and the pulp boiling chemicals that leave the boiler with the flue gases and they are then recycled back to the pulp process. The more efficient the recovery boiler's electrostatic precipitator is, the more closed the resulting process is. Both the environment and the forest company benefit ...
An electrostatic precipitator (ESP) is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit. In contrast to wet scrubbers which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and ...
