摘要： A method for removing condensable components from a fluid containing condensable components. The method involves optimizing the temperature of an initial feed stream including the condensable components through heat exchange and cooling to condense liquids there from. The liquids are removed to form a gas stream which is then compressed and after-cooled to form a high pressure stream. A portion of the high pressure stream is expanded to form a cooled low pressure stream which is mixed with the initial feed stream to augment cooling and condensation of condensable components in the initial feed stream.

摘要： Gas processing methodology for high efficiency recovery of propane and/or ethane from a natural gas feed stream. The method is conducted without turboexpansion. A natural gas stream is processed to have gas and liquid portions. The gas portion is cooled and flows to a refluxed absorber column and the liquid portion flows to a lower pressure distillation column. Bottoms of the absorber column are depressurized directly into a lower pressure distillation column and the overhead vapor stream is used to cool the feed and/or reflux streams. The overhead vapour stream from the lower pressure distillation column split into at least two streams with one being depressurized into the absorber to provide reflux and the second passed into the absorber column to provide further reflux.

摘要： Improved apparatus and methodologies for separating production water arising from conventional oil well production operations, the production water containing less than 1% oil-in-water, where the apparatus and methodologies may include the use of a large separation vessel configured to perform a phase separation mid-stream of a continuous fluid flow path, thereby increasing the overall retention time of the separation vessel.

摘要： Gas processing methodology for high efficiency recovery of propane and/or ethane from a natural gas feed stream. The method is conducted without turboexpansion, and in some embodiments, without the use of a refrigeration system. A natural gas stream is processed to have gas and liquid portions. The gas portions are cooled and flow to a refluxed absorber column and the liquid portions flow to a lower pressure distillation column. Bottoms of the absorber column are depressurized into a separator, with the separator overhead vapor being used as a source of absorber column reflux. The separator liquids are fed into the lower pressure distillation column and the distillation column overhead vapor stream is used to cool the feed and/or reflux streams. The overhead vapour stream from the lower pressure distillation can be recycled to the absorber, either as a recycle or a source of reflux.
