Conclusions A consideration of the economics of installing a leaf type of filter for crude oil in a new mill or as a replacement for existing filtration equipment must take into account the following advantages which a pressure leaf filter offers: Entire filter operation can be handled by a single operator with no assistance required for cleaning; complete elimination of cost of filter cloths and Viskon papers normally used to dress filter presses; elimination of storage, handling, cutting, etc., of cloths and papers; completely enclosed, leak‐free filter installation; drier filter cakes with less air‐blowing time and lower air consumption; a permanent filter medium (woven wire cloth) of stainless steel which cannot corrode, or rupture during operation, thereby causing passage of solids into filtered oil; high degree of solids removal, resulting in low refining losses; a cleaner filter station; less strenuous labor; and economical construction in carbon steel.
