Patent ID: 7314506

Claim:
A low temperature purifier for processing a matrix fluid to remove one or more impurities, comprising: a pre-cooler receiving the matrix fluid at a first temperature, pressure, and flow rate and outputting the matrix fluid at a second temperature that is lower than the first temperature; a purifier element comprising a volume of a high surface area material; a container comprising a steel pipe for containing the purifier element comprising a metal particle filter that comprises sintered, pressed, and/or plated nickel, stainless steel, corrosion resistant alloy, and/or an alloy selected for removing a particular one of the impurities, the container including an inlet for receiving the matrix fluid, wherein the input matrix fluid comprises a quantity of an impurity greater than about 100 parts per billion from the pre-cooler and an outlet for outputting the matrix fluid after the matrix fluid flows through the purifier element, wherein the output matrix fluid comprises less than 100 parts per billion of the impurity; and a cooler in thermal contact with an outer surface of the container cooling the outer surface of the container to a purifying temperature, the purifying temperature being selected to be below ambient temperature and above a phase change point of the matrix fluid at the pressure and the flow rate of the matrix fluid.
