Two-Phase Impure Steam Flow

Abstract

A device has been developed to remove the prominent impurity carbon dioxide gas from steam. The technique consists of a heat exchanger that condenses some of the impure steam to produce a pure condensate. The condensate is fed back to the shell side of the heat exchanger for conversion to pure steam while cooling the impure steam on the tube side. This regenerator, called the Inverse Flash Steam Purifier, is a small, self contained system with no moving parts nor electrical power requirements. The Inverse Flash Steam Purifier concept was tested in the laboratory and found to have very promising performance characteristics. Carbon dioxide levels were reduced from over 100 ppm to less than 3. This allows consideration of using the concept to purify shore-to-ship steam. Keywords: Steam purity; Clean steam; Steam purification; Carbon dioxide removal; Noncondensible gas removal.
