He has made significant contributions to the field of environmental technology, particularly in the treatment of gases containing hydrogen sulphide. His innovative approach has led to the development of a unique process that addresses the challenges associated with hydrogen sulphide emissions.
Latest Patents
Keesman holds a patent for a continuous process to treat a hydrogen sulphide comprising gas. This invention involves several key steps. First, the hydrogen sulphide gas is contacted with an aqueous alkaline solution that includes sulphide oxidising bacteria. This results in a loaded aqueous solution containing sulphide compounds and bacteria. Next, the loaded solution is treated with an oxygen comprising gas to regenerate the bacteria, producing a liquid effluent that is partly reused in the initial step. Finally, elemental sulphur is separated from the loaded solution or the liquid effluent, with the oxygen supply being controlled based on its measured consumption.
