摘要： Modifications are made to the standard process for the manufacture of ammonia and related compounds, resulting in lower operating costs through reduced total energy consumption. In one aspect of the invention, this is achieved by directing ammonia gas through one feed line, and carbon dioxide gas and steam through another feed line, into a closed reaction chamber to form ammonium carbonate. The formation of this solid compound results in a reduced pressure in the chamber. This reduced pressure can be used to drive heat engines in the reactant feed lines. In another aspect of the invention, the cost of running the potassium carbonate loop while the rest of the system is down is reduced by constructing an alternate pathway along part of the loop. The carbon dioxide gas and water vapor formed by the heating of the potassium bicarbonate flow through a heat engine and are cooled. The cooled water vapor and carbon dioxide gas are then recycled. The reactant gases may be liquified and revaporized in the event of reactor shutdown, and heat-exchange means may be associated with the system to provide at least a portion of the heat of vaporization of the liquified reactants. The heat-exchange means can thus produce a refrigerating fluid as a result of the vaporization of the reactants.
摘要翻译： 对制造氨和相关化合物的标准方法进行了修改，从而通过降低总能量消耗降低运行成本。 在本发明的一个方面，这是通过将氨气引导通过一条进料管线和将二氧化碳气体和蒸汽通过另一种进料管线导入封闭的反应室来形成碳酸铵来实现的。 该固体化合物的形成导致室中的压力降低。 这种减压可用于驱动反应物进料管线中的热机。 在本发明的另一方面，通过沿循环的一部分构建一个替代路径，减少了运行碳酸钾回路而系统的其余部分下降的成本。 通过加热碳酸氢钾而形成的二氧化碳气体和水蒸汽流过热机并被冷却。 然后将冷却的水蒸气和二氧化碳气体再循环。 在反应堆关闭的情况下，反应物气体可以被液化和再蒸发，并且热交换装置可能与系统相关联以提供液化反应物的至少一部分蒸发热。 因此，热交换装置可以由于反应物的蒸发而产生冷冻液。

摘要： A plurality of independent, closed Rankine cycle power plants, each of which has a vaporizer, is operated by serially applying a medium or low temperature source fluid to the vaporizers of the power plants for producing heat depleted source fluid. A preheater is provided for each vaporizer; and said heat depleted source fluid is applied to all of the preheaters in parallel. The heat depleted source fluid thus serves to heat the operating fluid to the evaporization temperature, while the source fluid applied to the vaporizers supplies the latent heat of vaporization to the operating fluid of the power plant. The present invention is advantageous, as compared to a conventional cascaded power plant of the type described, because the temperature drop of the source fluid can be increased without reducing the efficiency. Alternatively, the temperature drop can be maintained but the efficiency can be increased. In either case, the power produced by the power plant according to the present invention is increased.
