Abstract
The opportunity for mercury vapor, a common component of natural gas, to form a corrosive amalgam with the aluminum construction material of a cryogenic heat exchanger used in natural gas liquefaction operations is greatly minimized by cooling the mercury-containing gas to a temperature at or below the freezing point of mercury prior to introducing the gas to the heat exchanger.
