Abstract:
1. A magnetic filter for separating magnetic and non-magnetic contaminants from a liquid process stream in a refinery or a chemical plant that comprises: a housing having an opening that is sealed with a removable cover, a process stream inlet and a process stream outlet, and an interior region between the inlet and outlet; a magnetic core assembly which is detachably positioned in the interior and that comprises: a screen having an upper rim and enclosing a lower portion of the magnet core assembly wherein the screen is configured to capture contaminants thereon; and a plate support assembly secured in the interior of the housing and defining upper and lower support perimeters such that the upper rim of the screen is positioned on the lower support perimeter and a support plate of the magnetic core assembly is positioned on the upper support perimeter, wherein the support plate of the magnetic core assembly and the upper rim of the screen forms a flow channel so that as the liquid process stream flows from the inlet to the outlet, the liquid travels through the channel, passes the elongated non-magnetic sleeves so that magnetic contaminants adhere to the exterior of the non-magnetic sleeve and finally through the screen where contaminants of the desired sized are removed to form a treated liquid process stream that leaves the interior via the outlet.
