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 performing dampening for fluctuations in the streams conducted away from the adsorbent bed unit. The process may be utilized for swing adsorption processes, such as rapid cycle TSA and/or rapid cycle PSA, which are utilized to remove one or more contaminants from a gaseous feed stream.

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.
