A number of retorting techniques exist, one or two of them even being used in pilot projects around the world. In Brazil, for example, a pilot surface retort called the Petrosix process produced the equivalent of 1.4 million barrels of shale oil and other products during 1999.>>nap.edu <<technologies of retorting processing of oil shales are of most interest today: - the process “Petrosix” of “Petrobras” in Brazil; - the process “TOSCO-l l” in the USA; - the process “LURGI” in Germany www.petroleumnews.com/pdfarch/408741589.pdf BRAZIL The oil shale resource base is one of the largest in the world and was first exploited in the late nineteenth century in the State of Bahia. In 1935 shale oil was produced at a small plant in Sìo Mateus do Sul in the State of Paran… and in 1950, following government support, a plant capable of producing 10 000 b/d shale oil was proposed for Trememb», Sìo Paulo. Following the formation of Petrobras in 1953, the company developed the Petrosix process for shale transformation. Concentrating its operations on the reservoir of Sìo Mateus do Sul, the company brought a pilot plant (8 inch internal diameter retort) into operation in 1982. Its purpose is for oil shale characterisation, retorting tests and developing data for economic evaluation of new commercial plants. A 6 foot (internal diameter) retort demonstration plant followed in 1984 and is used for the optimisation of the Petrosix technology. A 2 200 (nominal) tons per day, 18 foot (internal diameter) semi works retort (the Irati Profile Plant), originally brought on line in 1972, began operating on a limited commercial scale in 1981 and a further commercial plant Ò the 36 foot (internal diameter) Industrial Module retort was brought into service in December 1991. Together the two commercial plants process some 7 800 tonnes of bituminous shale daily. The retort process (Petrosix) where the shale undergoes pyrolysis yields a nominal daily output of 3 870 barrels of shale oil, 120 tonnes of fuel gas, 45 tonnes of liquefied shale gas and 75 tonnes of sulphur. Output of shale oil in 1999 was 195.2 thousand tonnes. The Ministry of Mines and Energy quotes end-1999 shale oil reserves as 445.1 million m3 measured/indicated/inventoried and 9 402 million m3 inferred/estimated with shale gas reserves as 111 billion m3 measured/indicated/inventoried and 2 353 billion m3 inferred/estimated. Canadians get their stuff down there to be tested: <<Interest has been shown in the New Brunswick deposits for the potential they might offer to reduce sulphur emissions by co-combustion of carbonate-rich shale residue with high-sulphur coal in power stations>>
