摘要： A natural gas liquefaction system and process wherein excess refrigeration available in a typical natural gas liquefaction system is used to cool the inlet air to gas turbines in the system to thereby improve the overall efficiency of the system. A cooler is positioned in front of the air inlet of each gas turbine; and coolant (e.g. water) is flowed through each of the coolers to cool the ambient air as it flows into the gas turbines. The water, in turn, is cooled with propane taken from a refrigerant circuit in the system which, in turn, is used to initially cool the natural gas which is to be liquefied.

摘要： 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.

摘要： Liquefied natural gas (LNG) boil off gas (BOG) and/or end flash gas (EFG) can be used to recondense refrigerant vent gas. For example, a method can include: passing LNG BOG through a first condensing heat exchanger and/or passing an EFG from liquefaction system through a second condensing heat exchanger; and condensing the refrigerant vent gas in the first and/or second condensing heat exchangers, wherein (when using the first condensing heat exchanger) the LNG BOG is the coolant in the first condensing heat exchanger and (when using the second condensing heat exchanger) the EFG is the coolant in the second condensing heat exchanger, and wherein (when using both condensing heat exchangers) the first and second condensing heat exchangers are in parallel and not in series.
