Monday, Oct 01, 2012

PROVIDENCE, R.I., Sept. 28, 2012 /PRNewswire/ -- HDS International Corp. (OTCQB:  HDSI), a green technology company providing renewable energy and eco-sustainability solutions, today announced that the United States Patent & Trademark Office has granted patent no. 8,197,857 "Method for Eliminating Carbon Dioxide from Waste Gases."

Purification of process gas streams by the removal of acid gases, such as carbon dioxide, is required in many major industrial processes such as hydrogen manufacture for refinery hydrotreating, synthesis gas manufacture from coal, purification of natural gas, and ammonia manufacture, among other applications.  Bulk removal of acid gases from such streams is usually accomplished by use of a scrubbing solution composed of a solvent.

The invention preserves the advantages of prior methods for eliminating carbon dioxide from waste gases while providing new advantages not found in currently available methods and overcomes many disadvantages of such currently available methods.

The patent covers the elimination of carbon dioxide from waste gases.  Additionally, the invention can transfer carbon dioxide in increased concentrations for growth of algae; consists of a photobioreactor system used in the method for increased production of algae; and provides a method for operating an open-pond system using carbon dioxide from waste gases.

Alexander Chirkov, Ph.D., Chief Scientific Officer of HDS International and inventor of the patent, licensed by the Company, today commented, "Today's announcement helps solidify our intellectual capital portfolio and serves as recognition of our novel physical and economical approach to solving the significant and growing problem of carbon dioxide pollution."
