Usefulness of particulate cyclone in air pollution control

Purpose - The aim of this paper is to provide basic information on the types of particulate cyclones separators used in the chemical and process industries, their principles of operation and factors affecting their performance.Design methodology approach - A general review of the types of particle cleaning cyclones used in the chemical and process industries was carried out and the principles guiding their operation and performance discussed. Information which could aid the choice of cyclone for new applications is also discussed.Findings - It was concluded that the choice of cyclone for any application is associated with a trade-off between two contrasting performance indicators (collection efficiency and pressure drop). Adequate and accurate data gathering is essential right from the design stage for smooth operation of cyclone.Originality value - The paper highlights the general principle of operation of cyclone separators and the factors that affect their performance.
