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.

Preparing hydrocarbon streams for storage

A plant and process are used to liquefy and purify a high pressure ethane feed stream. The plant includes a cascaded refrigeration system that refrigerates the ethane feed stream. The refrigeration system includes a propylene circuit, an ethylene circuit and a mixed refrigerant circuit. The mixed refrigerant circuit includes a refrigerant that includes ethane and methane. The plant includes a demethanizer that is configured to remove methane and other natural gas liquids from the refrigerated ethane stream.

Low pressure ethane liquefaction and purification from a high pressure liquid ethane source

A process that is configured for treating natural gas mixed with carbon dioxide (CO) in high concentrations of 30% mole by volume or more. In one embodiment, the process comprises contacting a first feedstream comprising liquid natural gas (LNG) with a feedstock comprising methane to form an overhead product comprising methane vapor and a bottom product comprising carbon dioxide (CO). The embodiment can also comprise liquefying the methane vapor to form a LNG product and using the LNG product as the liquid natural gas (LNG) in the first feedstream.
