摘要： A system for removing freezing components from a feed gas includes a heavy hydrocarbon removal heat exchanger and a scrub device. The scrub device includes a scrub column that receives a cooled feed gas stream from the heat exchanger and a reflux separation device. Vapor from the scrub column is directed to the heat exchanger and cooled to create a reflux stream that includes a liquid component. This reflux stream is directed to the reflux separation device and a resulting liquid component stream is used to reflux the column. Vapor from the reflux separation device is expanded and directed to the heat exchanger, where it provides refrigeration, and a processed feed gas line.

摘要： Underwater gas pressurization units and liquefaction systems, as well as pressurization and liquefaction methods and gas field development methods are provided. Gas is compressed hydraulically by seawater introduced into vessels and separated from the gas by a water immiscible liquid layer. Tall, possibly vertical helical vessels are used to reach a high compression ratio that lowers the liquefaction temperature. Cooling units are used to liquefy the compressed gas, possibly by a coolant which is itself pressurized by a similar mechanism. The coolant may be selected to be liquefied under surrounding seawater temperatures. The seawater which is used to pressurize the gas may be used after evacuation from the vessels to pressurize intrastratal gas in the production stages and broaden the gas field development.

摘要： An improved method of supplying pressurized cold gas consistently of predominately N2 and He at low flow rate (typically under 1 g/s) with a desired N2 liquid fraction to an instrument requiring such is disclosed. Pressurized ultra-dry nitrogen gas of a controlled mass-flow rate is cooled inside fine coils bathed in liquid nitrogen to condense it to a vapor fraction less than about 20% and typically under 3%. A second gas stream consisting of predominately nitrogen plus helium, supplied from a controlled pressure, is cooled in a separate set of coils to an exit mean temperature significantly above the temperature of saturated nitrogen vapor in this mixture. The fluid from the first (condensed) mixture is injected into the cooled gas from the second mixture and transferred through a thermally insulated line to the input of the instrument needing a supply of cold gas of a target vapor fraction.

摘要： 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.

摘要： 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.

摘要： A compact assembly of a liquefied natural gas, (LNG)-mixed hydrocarbon refrigerants, (MR), arranged on a single shaft assembly for individual expanding the LNG and MR streams including sealing means for separating and isolating the processing of a LNG stream and MR stream at a pre-selected location intermediate the ends of the single shaft assembly. The liquefied natural gas, LNG, stream is coupled to a hydraulic turbine expander mounted on the single shaft assembly adjacent a first end thereof. The hydraulic turbine expander has two phase expansion capabilities. The hydraulic expander is enclosed in a vessel mounted between one end of the sealing means and beyond the first end of the shaft assembly for isolating the expander. The LNG stream and the vessel are arranged to traverse a pre-selected path within the vessel. The compact assembly may include a induction motor means mounted to the shaft assembly adjacent the sealing means. At least a single MR hydraulic turbine expander mounted to the single shaft assembly adjacent a second end of the shaft assembly. Each of the hydraulic turbine expanders having runner means mounted to the shaft assembly to be rotatably responsive to the fluid streams coupled thereto for rotating the shaft assembly and thereby the induction motor means functioning as an electrical power generator. The remaining portion of the shaft assembly is enclosed in a MR vessel for isolating the MR expander and the second end of the shaft assembly. The MR vessel is designed to have a MR inlet and outlet for causing the MR stream to follow a path in the opposite direction from the LNG stream to offset the thrust forces generated by the hydraulic turbine. The thrust forces can be offset without the need for an individual thrust equalizing mechanism.
