The Petrobras oil shale retorting process, utilizes the particle range of +1/4 inch - 3 1/2 inches. The UPI plant in Sao Mateus do Sul has over 106,000 hours of operation, has processed over 6,200,000 metric tons of shale and has produced almost 3,000,000 barrels of shale oil. However, the nature of the raw oil shale is such that the amount of shale less than 1/4 inch that is mined and crushed and returned to the mine site is about 20 percent, thereby, increasing the cost of oil produced by a substantial number. Petrobras has investigated several systems to process the fines that are not handled by the 65 MTPH UPI plant and the 260 MTPH commercial plant. This paper provides an updated status of each of these processes in regard to the tests performed, potential contributions to an integrated use of the oil shale mine, and future considerations.
