Title:
DEVICE AND METHOD FOR TWO-BED HYDRATE CONTINUOUS CO2 CAPTURE
Document Type and Number:
WIPO Patent Application WO/2022/096026
Kind Code:
A1
Abstract:
A device and a method for two-bed hydrate continuous CO2, comprising a first fixed bed hydrate reactor, a second fixed bed hydrate reactor, a solution circulation system, an air intake system, and an air exhaust system. The first fixed bed hydrate reactor and the second fixed bed hydrate reactor are respectively connected in series to the air intake system, the air exhaust system, and the solution circulation system, and the first fixed bed hydrate reactor is connected in parallel to the second fixed bed hydrate reactor. A cold medium fluid and a hot medium fluid output by a compression refrigeration system alternately flow into a heat exchange pipe coil of the first fixed bed hydrate reactor and the second fixed bed hydrate reactor, and the two fixed bed hydrate reactors alternately generate hydrate generation and decomposition reactions, thereby implementing continuous capture and separation of CO2. In the present invention, the two fixed bed hydrate reactors are used for alternately carrying out hydrate generation and decomposition to implement dynamic continuous CO2 separation, thus being able to raise cyclical material utilization rates, and also effectively improve separation efficiency.
