Use of ferrous powder for increasing the efficiency of solid particle filtration in natural gas cyclones

ABSTRACTThis paper investigates the experimental feasibility of using magnetic forces to enhance the efficiency of the overall solid–gas separation in cyclone separators used in gas treatment. More specifically, the use of adhesive ferrous powder to further increase the lateral forces on the solid particles is investigated. The size distribution of the escaping solid particles with clean gas is compared between the conventional cyclone design and the proposed technique. It is shown that these additional forces are added to the centrifugal force, enhancing the separation efficiency in conventional cyclones, particularly for smaller particles.
