    摘要： The present invention discloses apparatuses, systems, and methods for utilizing oil-free gas in a gas processing system. In some embodiments, an oil-free or “dry” gas is provided by a gas source to an oil-free compressor, such as a dry seal compressor, which charges a receiver vessel or vessels, which then provides the oil-free gas to at least one piece of processing equipment, such as an injection compressor or compressors for use in EOR, carbon sequestration, sour gas injection, or other gas handling operations. The methods and systems may include a controller for charging the receiver vessel when the pressure in the vessel decreases below a low pressure threshold and reducing the charging flow rate when the pressure in the vessel meets or exceeds a high pressure threshold in the vessel, thereby maintaining an operational pressure in the vessel.

    摘要： A drive system for a refrigeration compressor such as is used in a natural gas liquefaction plant, allowing the desired compressor speed and maximum turbine efficiency to be maintained throughout varying ambient temperature conditions. A gas turbine is used with an electric starter motor with drive-through capability located on a common drive shaft between the turbine and the compressor. A variable frequency drive (VFD) is connected between the electrical power grid and the electric motor for smooth startups, but also to allow excess turbine mechanical power to be converted to electrical power by the motor operating as a generator, and delivered to the grid at the grid frequency. Pulse width modulation technology may be used to reduce harmonic distortion in the VFD's output. The starter motor also functions as a helper motor when the turbine output is insufficient to drive the compressor at the rotational speed needed to meet throughput requirements.

    摘要： A hydrocarbon processing method, including processing a gaseous hydrocarbon stream to form a first production stream and a first injection stream; and compressing the first injection stream in a compressor placed at a selected location below a surface of a sea; wherein the location of the subsea compressor relative to a nearest inhabited area is determined based on a bubble plume trajectory of a model leak of the first injection stream from the compressor; and wherein the bubble plume trajectory is determined using one or more crossflow momentum parameters is disclosed herein. Also disclosed are hydrocarbon processing facilities having subsea compressors placed at such selected locations, processes for designing such hydrocarbon processing facilities, and a mathematical model useful in such methods, processes, and facilities.
