Abstract: A method for enhancing geological storage by injecting nanoparticles to stabilize CO2 microbubbles, which belongs to the technical field of multiphase flow. The method first improves the physical properties of the fluid by pre-mixing CO2 and nanoparticles, and then the fluid is transported to the underground through high-pressure pipelines, and then CO2 microbubbles containing nanoparticles are generated through a dense perforated plate arranged by an injection well to improve the dissolution rate and sweep efficiency of the gas in the saline aquifer, so as to enhance the later mixing of the fluid. The combined injection can improve CO2 storage capacity and storage safety, and further reduce the risk of gas leakage in the reservoir.

Abstract: The present disclosure provides an apparatus and a method for hydrate-based wastewater treatment and cold storage. The apparatus for hydrate-based wastewater treatment and cold storage includes a water chilling unit, a hydrate-based cold storage tank, an airflow disturbance device, a water layer positioning system, a spraying system, a suction filtration system, a heat exchange system, and a system monitoring device. The water chilling unit provides a secondary refrigerant at a low temperature. The secondary refrigerant flows through an evaporator coil in the hydrate-based cold storage tank for heat exchange. The airflow disturbance device induces hydrate nucleation. The water layer positioning system positions a contact surface between a water layer and a hydrate former after hydrate decomposition to facilitate drawing and separation of the treated upper water layer. The spraying system and the suction filtration system enhance the solid-liquid separation efficiency to improve the removal rate of pollutants.
