Introduction

Junfei Chen is a notable inventor based in Wuhan, China. He has made significant contributions to the field of oil-water separation technologies, holding a total of 3 patents. His innovative methods utilize advanced techniques in nuclear magnetic resonance (NMR) to enhance the efficiency of oil-water separation processes.

Latest Patents

One of his latest patents is titled "Method for separating oil-water two-phase NMR signals by using dynamic nuclear polarization." This method involves using a combination of a non-selective free radical and a selective relaxation reagent to enhance the NMR signal of either the oil phase or the water phase. The relaxation reagent selectively suppresses dynamic polarization enhancement, allowing for the effective separation of the two-phase signals. This approach is noted for its simplicity, ease of operation, and efficiency in separating NMR signals of oil and water phases.

Another significant patent is "Method for measuring oil-water distribution using dynamic nuclear polarization for magnetic resonance imaging (DNP-MRI)." This method enhances the NMR signal of a fluid phase in a sample containing oil and water by adding a free radical. The process includes performing an MRI experiment and comparing images with and without DNP enhancement. The method is recognized for its convenience, short measurement time, and high efficiency in determining fluid phase distribution.
