Abstract: The present invention belongs to the technical field of hydrate application, and proposes an electric field-based CO2 capture apparatus by a hydrate method and a method therefor. Small particles of hydrate are generated by incoming seawater and incoming hydrate former at low temperature and high pressure. After flowing through the electric field, the particles are quickly formed, and then separated, dried and compressed efficiently by a solid-liquid separation chamber. Finally, hydrate blocks are produced. The combination of a stirring method, a spraying method and an external electric field can effectively solve the characteristics of slow hydrate formation and long cycle. The solid-liquid separation chamber can be designed to efficiently filter out the hydrate particles and prevent a filter plate from blocking. The use of heat exchange chambers in many places make the cooling amount in the discharged waste recycled, greatly thereby improving the utilization efficiency of energy and economic benefits.

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 invention discloses an electric heating thermal management system for an oil and gas transportation pipeline based on renewable energy and CO2 energy storage. It transmits the feedback data value through a data collection device arranged in the pipeline to the early warning device by the control device. After analysis and processing, the early warning device can feed back the data value to the control device and the remote operation device in two modes. Different degrees of heating amount can be generated for the oil and gas transportation pipelines at different positions in different modes. Hierarchical and distributed management control for the oil and gas transportation pipelines can be targetedly conducted in unblocked, easily blocked and blocked positions of the oil and gas transportation pipeline. The present invention couples the renewable energy electricity supply device and the CO2 energy storage device.
