Filtration process and equipment studies for coal liquefaction processes. Quarterly report, March--May 1977
Filtration rates in excess of 700 pounds/hour/square foot were obtained at 100 psid differential pressure 600/sup 0/F, 100 psid, 4 and 2 mil/cycle, 2 second immersions). Filtration rate dependence upon differential pressures up to 100 psid has been studied. Rates in excess of 450 pounds/hour/square foot (600/sup 0/F, 100 psid, 5 second immersions, 4 mils/cycle) were obtained. A timing device has been installed on the test leaf allowing more accurate rate calculations, particularly for short immersion times. Rates obtained for two second immersions, simulating a 12 rpm drum speed, were above 650 pounds/hour/square foot (600/sup 0/F, 70 psid, 4 mils/cycle blade advance). Filter aid usage under these conditions would be high, but can be lowered by reducing the knife advance rate.
