Title: Innovations of William Douglas Thomson
Introduction
William Douglas Thomson is a notable inventor based in Southampton, GB. He has made significant contributions to the field of chemical engineering, particularly in the recovery of olefins from cat-cracked gases. With a total of 2 patents to his name, Thomson's work has implications for both safety and efficiency in chemical processes.
Latest Patents
Thomson's latest patent focuses on a process for recovering olefins from cat-cracked gas without accumulating dangerous amounts of nitrogen oxides. This innovative method begins with scrubbing a stream of cat-cracked gas to remove acid gases, including nitrogen dioxide (NO₂). The gas is then passed through a depropanizer fractionation tower, where hydrocarbons with four or more carbon atoms are recovered in the bottoms. The overhead, consisting of hydrocarbons with three or fewer carbon atoms, is sent to an absorber demethanizer tower. Here, hydrocarbons with two or more carbon atoms are recovered at temperatures no lower than about -45.56°C (-50°F). The overhead from this tower, which includes methane, hydrogen, and trace amounts of nitrogen oxide, is chilled to condense and recover trace amounts of heavier gases. This process is designed to prevent the oxidation of nitric oxide (NO) into nitrogen dioxide (NO₂) and to avoid the accumulation of unwanted nitrogen oxides.
