This paper presents the general layout and main features of a new method for utilising ой shale: integrated tri-generation system. This new scheme is expected tobe more efficient and environment-friendly, as well as a less-costly method, for producing electric power and synthetic (i.e. liquid and gaseous) fuels from oil shale, compared with traditional utilisation methods. By integrating the gasifier, circulating fluidised-bed combustor (CFBC), retort and combined-cycle turbine system in one plant, higher efficiencies can be achieved as well as lower costs of the final products.
A preliminary analysis of the OSITGS was conducted to determine the nature and expected rates of various effluent streams emergingfrom such a processing facility. Mining and processing of oil shale will significantly disturb the environment (e.g. pollution by dust particles and ash derived from oil shale as well as various gaseous emissions will ensue in the neighbourhood of the development project). However, it is likely that solid-waste handling (including ultimate disposal) as well as land use impacts will be of greater concern than air emissions from the proposed oil shale operations. It is predicted that the proposed OSITGS will be ап environmentally acceptable technique for producing synthetic fuels and electricity from oil shale.
