Abstract: The present invention discloses a gas hydrate-based particulate/waste gas simultaneous removal system and method. R134a can be used to synthesize particulates/coking waste gases into gas hydrate, which can realize the simultaneous removal of particulates/coking waste gases with no pollution and low energy consumption. The system comprises a waste heat recovery device, a gas hydrate primary dust removal tower, a solid-liquid separation primary tower, a gas hydrate secondary dust removal tower, a solid-liquid separation secondary tower, a gas hydrate decomposition pool, a gas-solid separation tower and a low temperature fractionation device. The present invention can achieve the removal of harmful substances such as heavy metals and coking waste gases while removing particulates. Compared with the current particulate control and waste gas treatment device, the gas hydrate method-based device is greatly simplified and can effectively remove multiple pollutants and realize energy saving and environmental protection.

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.
