Abstract: A method of producing LNG. According to the method, a natural gas stream is compressed using first and second compressors. A cooler cools the natural gas stream so that the second compressor produces a cooled, compressed natural gas stream, which is liquefied in a liquefaction process. The liquefaction process uses a refrigerant compressor configured to compress a stream of refrigerant used to chill, condense, or liquefy the cooled, compressed natural gas stream. Using a heat recovery steam generation (HRSG) system, heat is recovered from a power source of the refrigerant compressor. A stream of pressurized steam is generated from the recovered heat. At least one of the first and second compressors is powered using at least part of the stream of pressurized steam.

Abstract: Systems and methods are provided for separation of CO2 from dilute source streams. The systems and methods for the separation can include use of contactors that correspond radial flow adsorbent modules that can allow for efficient contact of CO2-containing gas with adsorbent beds while also facilitating use of heat transfer fluids in the vicinity of the adsorbent beds to reduce or minimize temperature variations. In particular, the radial flow adsorbent beds can be alternated with regions of axial flow heat transfer conduits to provide thermal management. The radial flow structure for the adsorbent beds combined with axial flow conduits for heat transfer fluids can allow for sufficient temperature control to either a) reduce or minimize temperature variations within the adsorbent beds or b) facilitate performing the separation using temperature as a swing variable for controlling the working capacity of the adsorbent.

Abstract: Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve passing an input feed stream through two swing adsorption systems as a purge stream to remove contaminants, such as water, from the respective adsorbent bed units. The wet purge product stream is passed to a solvent based gas treating system, which forms a wet hydrocarbon rich stream and a wet acid gas stream. Then, the wet hydrocarbon rich stream and the wet acid gas stream are passed through one of the respective swing adsorption systems to remove some of the moisture from the respective wet streams.

Abstract: A method and apparatus for producing liquefied natural gas (LNG) from a natural gas stream. Heavy hydrocarbons are removed from the natural gas stream in a separator to generate a bottom stream and a separated natural gas stream, which is used as a coolant in a heat exchanger to generate a pretreated natural gas stream. The pretreated natural gas stream is compressed and cooled to form a chilled pretreated natural gas stream, part of which forms a recycle stream to exchange heat with the separated natural gas stream in the heat exchanger, thereby generating a cooled recycle stream. The temperature and pressure of the cooled recycle stream are reduced. The cooled recycle stream is then separated into an overhead stream and a reflux stream, which is directed to the separator. The chilled pretreated gas stream is liquefied to form LNG.
