Title: Innovations by Charles A Durr
Introduction
Charles A Durr is a notable inventor based in Houston, TX (US). He has made significant contributions to the field of natural gas processing, holding a total of 8 patents. His work focuses on improving the efficiency of liquefied natural gas (LNG) treatment processes.
Latest Patents
Among his latest patents is a method for removing mercaptans from LNG. This innovative process allows for the liquefaction of natural gas containing mercaptans without specific pretreatment. By concentrating mercaptans into a distillate stream, the equipment required for their removal is significantly smaller. This is achieved by treating mercaptans at a point in the process where the flow rate is much lower. Additionally, a portion of the treated distillate stream can be reinjected to facilitate mercaptan absorption in the upstream distilling stage.
Another significant patent involves a process for removing nitrogen from LNG. This method utilizes an enhanced surface, reflux heat exchanger. In this process, a warm high-pressure LNG stream is directed countercurrently with a cool low-pressure LNG stream. This interaction chills the high-pressure stream and partially vaporizes the low-pressure LNG stream, effectively stripping nitrogen from the low-pressure LNG. The resulting product is LNG that is lean in nitrogen, enhancing its quality.
