Abstract
A novel design of filters for removing iron rust particulates and other polymeric sludge from refinery and chemical process streams that are paramagnetic in nature is provided. The performance of these filters is greatly enhanced by the presence of the magnetic field induced by magnets. Basically, the filter comprises a high-pressure vessel with means to support the plurality of magnets in the form of bars or plates that are encased in stainless steel tubes or columns. Filters with various configurations are disclosed for accommodating the removal of contaminants from the process streams of different industries, with high efficiency for contaminants removal, simple construction, low operational and maintenance costs, and low hazardous operation.
