摘要： The invention concerns a method of treating a pyrogas before gas separation. The proposed method ensures highly economical operation owing to the low energy requirements for compressing the pyrogas and low consumption of cooling water. This results from the relatively low pyrogas temperature and low pressure losses during the multistage compression, which in turn results from the organisation of the processes of cooling, by contact heat exchange between the pyrogas, flushing water and an operating fluid, cooling these components with an external medium in refrigeration units and with a cold carrier in the evaporators of absorption machines, and by preliminary cooling of the flushing water in the generators of these machines. The proposed method of obtaining industrial low temperatures in a vapour compression refrigeration machine is characterised by a high refrigeration coefficient and low consumption of cooling water. This is made possible by the transfer of the heat of condensation of the refrigerant to the atmospheric air and by supercooling the liquid refrigerant before the expansion processes using an absorption refrigeration machine and exploiting the heat carried away from the pyrogas by the flushing water in the column.
摘要翻译：本发明涉及在气体分离之前处理焦糖的方法。所提出的方法由于用于压缩焦化的低能量需求和低的冷却水消耗而确保了高度经济的操作。这是由于在多级压缩期间相对较低的焦糖温度和低压力损失，这又是由于冷凝过程的组织，通过焦rog子，冲洗水和工作流体之间的接触热交换而产生的，制冷装置中的外部介质，以及吸收机蒸发器中的冷载体，以及这些机器的发生器中的冲洗水的预冷。所提出的在蒸气压缩式制冷机中获得工业低温的方法的特征在于制冷系数高，冷却水消耗低。这可以通过将制冷剂的冷凝热转移到大气中，并且通过使用吸收式制冷机在膨胀过程之前使液体制冷剂过冷，并利用柱中的冲洗水来利用从焦heat带来的热量。

摘要： A method for removing gaseous pollutants from a polluted flue gas stream of an oil or coal-fired combustion furnace. A source of liquified combustible gas and a combustible gas-fired furnace are provided. The polluted flue gas stream is passed through a dust removal apparatus and removes flue dust from the flue gas stream so as to provide a de-dusted flue gas stream. Heat is recovered from the flue gas to generate power therefrom. The de-dusted flue gas is compressed to a pressure of at least 10 psi gauge using the generated power to at least in part compress the de-dusted flue gas. The compressed flue gas and the combustible gas are passed through at least one multi-sided heat exchanger, where the compressed flue gas is first passed through one side thereof and the liquified combustible gas in an at least partially vaporized state is passed through another side thereof. The compressed flue gas is cooled sufficiently by the combustible gas that water and at least one gaseous pollutant of NO2, SO2 and CO2 are condensed and separated from the compressed flue gas to provide reduced pollutant flue gas. Fully vaporized combustible gas is passed to the combustible gas-fired furnace and combusted to a further flue gas and the further flue gas is passed into the polluted flue gas stream.

摘要： The invention relates to a plant for extracting substances in a gas or mist form from a flow of gas. The plant includes in series a gas-flow collecting chamber (1), a compressor (5), a cooler (8) which functions to lower the gas temperature, and an expansion device (11) which functions to rapidly lower the pressure and the temperature of the gas flow and which includes a chamber (13) for separation of the condensation thus formed.

摘要： Improvement in a Ryan/Holmes separation of methane from carbon dioxide wherein the upper portion of a distillation column is operated at temperatures above the triple point of carbon dioxide, i.e., -70 F, while still effectuating a separation of methane from carbon dioxide. This is achieved by increasing the amount of non-polar liquid agent added to the condenser of the column to an amount sufficient to maintain the condenser and all portions of the column at such temperatures.
