Title: Innovations by Eh Deng in Hydrocarbon Recovery
Introduction
Eh Deng is an accomplished inventor based in Irvine, CA (US). She has made significant contributions to the field of hydrocarbon recovery, holding 2 patents that showcase her innovative approaches to improving efficiency in this area.
Latest Patents
One of her latest patents is titled "Methods and apparatus for high propane recovery." This invention involves methods and configurations for an improved propane recovery plant that utilizes an absorber column and a deethanizer column with an overhead condenser. The system produces a reflux condensate that is recycled to both the absorber and deethanizer columns. Additionally, a third recycling loop feeds propane from the absorber column into the deethanizer column in a gaseous form. The overhead condenser employs cold reject gas from the absorber and/or propane as a refrigerant, and preferred deethanizer columns include an integral water removal contactor.
Another notable patent is the "Cryogenic expander recovery process." This process describes the separation and recovery of C.sub.3 and heavier hydrocarbons from a gaseous hydrocarbon-containing feed stream, such as natural gas or refinery gas. The gaseous feed stream is cryogenically expanded, and the expanded gas is brought into contact with an absorption medium. The C.sub.3 and heavier components are liquefied and subsequently subjected to distillation and recovered as a liquid product.
