Title: Innovations of Chunhua Liu in Degassing Technology

Introduction

Chunhua Liu is a notable inventor based in Qingdao, China. She has made significant contributions to the field of degassing technology, holding a total of 3 patents. Her work focuses on developing efficient devices that enhance the quality of crude oil by removing gas and water content.

Latest Patents

One of her latest patents is the "Compact L-shaped cylinder-cone combined tubular three-stage axial flow degassing device." This innovative device utilizes an efficient degassing technology that includes a vertical high-speed swirling field, a horizontal rapid axial flow field, and a vertical reversing scrubbing field formed by a combination of vertical tubes. The first-stage degasser performs a vertical high-speed swirling degassing operation, effectively removing the gas phase from the gas-containing fluid and producing a primary gas and primary fluid. The microporous uniform mixer then breaks bubbles in the primary fluid, creating a gas-liquid uniform mixed flow. The second-stage degasser employs a horizontal vane wheel swirling method to generate rapid axial flow, further removing gas from the mixed flow and forming secondary gas and fluid. Finally, the third-stage degasser conducts a vertical reversing deep degassing operation, eliminating the liquid phase carried by the secondary gas and resulting in tertiary gas and fluid.

Another significant patent is the "Three-stage degassing and dewatering device." This device comprises a first-stage degasser, a second-stage degasser, an oil drainer, a rod electrode, a dewaterer, and a water drainer. The first-stage degasser implements an axial-flow type collision buffer degassing and dewatering operation, producing a first-stage crude oil after removing some gas and water. The second-stage degasser performs an elevated efficient degassing operation, resulting in a second-stage crude oil. The rod electrode creates a dynamic electric field with high frequency and voltage, working with the dewaterer to conduct a third-stage rapid dewatering operation, ultimately yielding qualified crude oil.
