Abstract: A method to recover and process hydrocarbons from a gas flare system to produce natural gas liquids (NGL), cold compressed natural gas (CCNG), compressed natural gas (CNG) and liquid natural gas (LNG). The method process provides the energy required to recover and process the hydrocarbon gas stream through compression and expansion of the various streams.

Abstract: A method of stripping carbon dioxide from a stream of natural gas to be used in the production of liquid natural gas (LNG) comprises the steps of: passing a stream of natural gas through a stripping column; injecting a stripping agent into the stripping column, the stripping agent stripping carbon dioxide from the stream of natural gas and exiting the stripping column as a liquid phase; passing the stripping agent exiting the stripping column through a regenerator column to generate a carbon dioxide gas stream and a recovered stripping agent stream; and cooling the recovered stripping agent stream using a cryogenic vapour generated in the production of LNG and injecting the cooled, recovered stripping agent stream into the stripping column as the stripping agent.

Abstract: A system for removing acid gases from a raw gas stream the system includes a cryogenic distillation tower. The tower receives and separates the raw gas stream into an overhead methane stream and a bottom liquefied acid gas stream. Refrigeration equipment downstream of the cryogenic distillation tower cools the overhead methane stream and returns a portion of the overhead methane stream to the cryogenic distillation tower as liquid reflux. The system also may include a first molecular sieve bed upstream of the distillation tower and a second molecular sieve bed downstream of the distillation tower. The first molecular sieve bed adsorbs water while the second molecular sieve bed adsorbs additional acid gases from the cooled overhead methane stream.

Abstract: In a cooling and compressing process, a wet feed gas (1) that is rich in carbon dioxide is scrubbed with water and with an antifreeze agent in a column (3) in order to produce a flow of gas that is rich in carbon dioxide, water-depleted and cooled, the flow of gas rich in carbon dioxide is compressed in a compressor (20) and a liquid rich in carbon dioxide (18) is vaporized in order to cool the water and antifreeze agent before sending them to the scrubbing operation, it being possible for the liquid to originate from an external source.

Abstract: A variable speed liquid LNG expander (X1) and a variable speed two-phase LNG expander (X2) in line, downstream from X1. The rotational speed of both expanders can be controlled and changed independent from each other. The speed of expander X1 and expander X2 is determined in such way that the amount of liquid LNG downstream from the PHS compared to the feed gas supply is maximized and the amount of vapor and boil-off downstream of X2 is minimized.

Abstract: Embodiments are directed to an expander having two or more hydraulic stages with different physical geometries. In an embodiment, a first hydraulic stage uses nozzle vanes machined with a first geometry, while a second hydraulic stage uses nozzle vanes machined with a second geometry. Different nozzle vanes can be combined to tune the performance of the expander as the optimal operating conditions change. In yet another embodiment, an expander is equipped with a generator having a double wound stator with two sets of parallel windings. For high operating loads greater than a threshold, a first set of windings operates while a second set of windings, operating at a lower frequency, is disconnected. For operating loads that are less than the threshold, the first set of windings is disconnected and the second set of windings operates, enabling the generator to continue to operate close to 100% load for less expander power.

Abstract: A process for liquefying natural gas in conjunction with producing a liquid stream containing predominantly hydrocarbons heavier than methane is disclosed. In the process, the natural gas stream to be liquefied is partially cooled, expanded to an intermediate pressure, and supplied to a distillation column. The bottom product from this distillation column preferentially contains the majority of any hydrocarbons heavier than methane that would otherwise reduce the purity of the liquefied natural gas. The residual gas stream from the distillation column is compressed to a higher intermediate pressure, cooled under pressure to condense it, and then expanded to low pressure to form the liquefied natural gas stream.
