Precoat filtration has been used as the liquid/solid separation process at both the Pittsburg and Midway Coal Mining Company, Fort Lewis, Washington, SRC I Pilot Plant and the SRC Pilot Plant at Wilsonville, Alabama. Johns-Manville's experience from other precoat filtration operations indicated that major improvements in filtration rate and operating costs should be possible. A Rotary Pressure Precoat Filter Test Leaf was designed and constructed which makes it possible to simulate the operation of a full scale rotary pressure precoat filter. Variables affecting the operation of the rotary pressure precoat filter were investigated in detail. At optimized operating conditions, the filtration rates were three to four times those achieved at Fort Lewis and almost an order of magnitude higher than those obtained at Wilsonville on another type of filter. It now appears possible to markedly reduce the filtration cost in coal liquefaction plants. This Report includes a review of precoat filtration principles, a description of the test equipment used, and a presentation of the effect of filtration variables as determined by studies with the Rotary Pressure Precoat Filter Test Leaf.
