Systems and methods for efficient heavy hydrocarbons removal

Abstract

Disclosed are systems and methods for processing liquefied natural gas (LNG). The method includes directing cooled natural gas to a first column, directing natural gas liquids from the first column into a second column, generating, by the second column, a reflux stream, and directing the reflux stream to a point upstream of the second column, wherein an introduction of the reflux stream enhances a removal of heavy hydrocarbons from a gas in the LNG facility. The method further includes directing an output of the second column to a third column, generating, by the third column, a solvent stream, and directing the solvent stream into an injection point, wherein the introduction of the solvent stream lowers a freezing point of a feed gas in the LNG facility.
