Coal-oil-mixture technology: a status report
Papers and discussions presented at the Second International Symposium on Coal-Oil-Mixture Combustion (November 27 to 29, 1979) are reviewed to assess the state of technology in this field. Environmental problems receive little attention; most appear soluble by current methods used to control emissions from coal burning. Economic studies indicate that converting oil-burning plants to COM burning would be profitable, even with retrofit costs. Experience with coal-oil mixtures (COM) has been encouraging in bench-scale tests, small boilers, and short-term plant tests, but extended, large-scale tests are needed prior to commercialization of COM. Major problems needing more investigation or plant experience are: lack of a definition of COM stability and a quick way to measure it; uncertainties as to COM structure and the mechanisms of how additives promote stability; heterogeneity of coals and oils; inadequate experience in COM storage and transportation; uncertainty about long-term effects of corrosion and erosion of components by COM, and existence of other possible operating problems. The US Department of Energy announced an expanded program for COM demonstration plants, and industrial firms are selling COM and offering to build plants to prepare it.
