Title: Yang Liu: Innovator in Natural Gas Liquefaction
Introduction
Yang Liu is a prominent inventor based in Allentown, PA (US), known for his contributions to the field of natural gas liquefaction. He holds a total of 4 patents, showcasing his innovative approaches to improving the efficiency of liquefied natural gas (LNG) production.
Latest Patents
Yang Liu's latest patents include significant advancements in the integrated nitrogen removal process during LNG production. One of his notable inventions is a method and apparatus for liquefying a natural gas feed stream while effectively removing nitrogen to produce a nitrogen-depleted LNG product. This process involves feeding a natural gas feed stream into the warm end of a main heat exchanger, where it is cooled and partially liquefied. The system separates the stream into nitrogen-enriched vapor and nitrogen-depleted liquid, which are then reintroduced into the heat exchanger for further cooling.
Another of his recent patents focuses on using a refrigerated heat pump for nitrogen removal in LNG production. This method entails passing a natural gas feed stream through a main heat exchanger to generate a first LNG stream. The liquefied or partially liquefied natural gas is then separated in a distillation column to yield a nitrogen-rich vapor product, with a closed-loop refrigeration system providing the necessary cooling.
