Title: Innovations of James W. Pervier
Introduction
James W. Pervier is a notable inventor based in West Chester, PA (US). He has made significant contributions to the field of natural gas liquefaction and nitrogen rejection processes. With a total of 3 patents to his name, Pervier's work has had a substantial impact on the industry.
Latest Patents
One of Pervier's latest patents is titled "Dual mixed refrigerant natural gas liquefaction." This patent describes a process and apparatus for liquefying natural gas using two closed cycle, multicomponent refrigerants. A low-level refrigerant cools and liquefies the gas by indirect heat exchange, while a high-level refrigerant cools and partially liquefies the low-level refrigerant through indirect multistage heat exchange. The high-level refrigerant is phase-separated to utilize lighter refrigerant components for the final refrigeration levels, avoiding multiple flash separations.
Another significant patent is "Nitrogen rejection from natural gas integrated with NGL recovery." This process outlines the recovery of methane, nitrogen, and natural gas liquids from a natural gas feed stream at high pressure. It integrates a nitrogen rejection stage, which includes a heat pump-driven distillation column and a natural gas liquids stage. This method allows for nitrogen rejection over a wide range of nitrogen concentrations in the feed stream.
