1983年年中投产的12,800吨/日重炼工艺可望提高产品产量和质量。第三代工艺也有望提高热效率。油页岩中的干酪根在热解时分解，并作为油气蒸气从岩石中释放出来。使用冷的进入的页岩进料来冷凝大部分油产品，大大降低了大多数其它地面冷凝方案所共有的外部冷凝设备的资本和操作成本。可以建立干馏条件，这将导致干馏在干馏床的顶部附近发生。在该水平下，页岩颗粒之间的接触压力最小。联合石油公司从事表层油页岩开采近40年，是固体上流开采的先驱。列出了燃烧脱碳页岩特性、燃烧室烟道气特性和油页岩工厂效率的表格。包括采矿和页岩制备燃料消耗在内的工厂效率是通过将净产品的热值除以原料页岩、购买电力的发电厂燃料和矿山和处置区的柴油燃料的热值之和来计算的。工艺开发和燃烧室设备的设计和选择仍在继续。«少
Reports that a 12,800-ton/d retorting process scheduled to start up in mid-1983 promises to improve its product yield and quality. A third-generation process is also expected to increase thermal efficiency. Kerogen in the oil shale is decomposed on retorting and is liberated from the rock as oil and gas vapors. Use of the cold incoming shale feed to condense the bulk of the oil product substantially reduces the capital and operating costs for external condensing equipment common to most other surface retorting schemes. Retorting conditions can be established which will cause the retorting to take place near the top of the retort bed. At this level, the contact pressure between shale particles is at a minimum. Union Oil has been involved in the development of surface oil shale retorting for close to 40 years and has pioneered the development of solids upflow retorting. Presents tables with combustion decarbonized shale properties; combustor flue-gas properties; and efficiency of oil shale plants. Plant efficiencies including fuel consumption for mining and shale preparation are calculated by dividing the heating value of the net products by the sum of the heating values of the raw shale, power plant fuel for purchased power, and diesel fuelmore » for the mine and disposal areas. Process development and combustor equipment design and selection is continuing.« less
