Title: The Innovative Contributions of James S. Lehr
Introduction
James S. Lehr is an accomplished inventor based in Wilmington, Delaware. He has made significant contributions to the field of chemical engineering, particularly in the treatment of spent refinery caustic. His innovative approach addresses environmental concerns associated with hydrogen sulfide and spent caustic solutions.
Latest Patents
James S. Lehr holds a patent for the "Treatment of Spent Refinery Caustic." This invention involves washing a hydrocarbon stream with a caustic solution to remove hydrogen sulfide reactively. The process results in a spent caustic solution that contains sulfide reaction products. The spent caustic solution is then stripped with concentrated carbon dioxide, effectively removing the sulfides and producing an overhead hydrogen sulfide stream and a bicarbonate-containing bottoms stream. The hydrogen sulfide can be converted into elemental sulfur or sulfuric acid, while the bicarbonate solution can be treated further to remove mercaptans and phenols.
