Abstract: A system and process that are configured to prepare incoming hydrocarbon feedstocks for storage. For incoming ethane gas, the embodiments can utilize a plurality of vessels to distill the incoming feedstock to vapor and liquid ethane that is suitable for storage. The embodiments can direct the vapor to a demethanizer column that is downstream of the vessels and other components. The process can include stages for distilling an incoming feedstock at a plurality of vessels to form a vapor and a liquid for storage; directing the vapor to a demethanizer column; and circulating liquid from the demethanizer column back to the plurality of vessels.

Abstract: A liquefaction system that is configured to use a single methane expander to provide primary refrigeration duty. The liquefaction system can include a first or main heat exchanger and a fluid circuit coupled with the heat exchanger, the fluid circuit configured to circulate a process stream derived from an incoming feedstock of natural gas. The fluid circuit can comprise a compression circuit, methane expander coupled with the compression circuit and the main heat exchanger, a sub-cooling unit coupled with the methane expander, the sub-cooling unit configured to form a liquid natural gas (LNG) product from the process stream, and a first throttling device interposed between the main heat exchanger and the sub-cooling unit. The first throttling device can be configured to expand the process stream to a process pressure that corresponds with the suction pressure internal to the compression circuit.

Abstract: A liquefaction process configured to facilitate thermal transfer in a heat exchanger during liquefaction of a natural gas feedstock. The liquefaction process can include compressing a process stream to a first pressure, the process stream comprising predominantly methane, cooling the process stream to a first temperature, expanding the process stream from the first pressure to a second pressure that is less than the first pressure, bleeding-off a first product from the process stream at the second pressure, and conditioning the first product for storage as liquid natural gas (LNG).

Abstract: A system and process for regenerating sieve materials in a gas processing system. The process can include circulating a cooling gas through sieve material of a first bed, the cooling gas having a first concentration of carbon dioxide (CO2) suitable for liquefaction into a liquid natural gas (LNG) product. The process can also include circulating a regenerating gas through sieve material of a second bed, the regenerating gas having a second concentration of carbon dioxide (CO2) that is greater than the first concentration of carbon dioxide (CO2) of the cooling gas.
