Filtration characteristics of Tacoma Filter Feed stock (TFF-216) and Wilsonville Filter Feed stock (SN 25260, Emery Feed Coal) were studied during the course of 24 experimental runs performed on the rotary pressure precoat filter test leaf. Tests at /sup 1///sub 2/ mil/cycle knife blade advance resulted in rates in excess of 325 lb/hr/ft/sup 2/ (100 psid, 3- and 4-sec immersions). Tests using CELITE AF13, a coarse grade filter aid, as a non-asbestos filled pre-precoat material indicate essentially no difference in filtration rate or filtrate ash content when compared with previous tests under similar conditions using the asbestos filled FIBRA-FLO 7C as the pre-precoat material. Initial test results on the filtration characteristics of the Wilsonville Filter Feed indicate filtration rates similar to those obtained with Tacoma Filter Feed. Costs based on those developed by Batchelor and Shih have been estimated for an average filtration rate of 500 lb/ft/sup 2//hr. Costs were as low as $0.56/bbl.
