Abstract: The invention provides a method and system for separating xenon-krypton mixed gas by hydrate formation process. The system is mainly composed of a gas hydrate generating unit, a heat exchanging unit and a gas-water separating unit: pre-cooled xenon-krypton mixed gas is injected from a bottom of a reaction tower, xenon gas in the mixed gas and water attached to a porous tray generate a xenon gas hydrate; and water is injected from a top of the tower to wet the porous tray, a generated hydrate particle is washed and collected to the bottom of the tower simultaneously to form a hydrate slurry, after passing through the heat exchanging unit, the xenon gas hydrate in the slurry is decomposed to form a gas phase flow and a water phase flow, and then enters the gas-water separating unit, and the xenon gas is separated from decomposed water.

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.

Abstract: The present invention belongs to the field of gas solubility measurement, and provides a measuring device and method for gas solubility in a natural gas hydrate solution system. The measuring device mainly comprises a reaction system, a sampling system and a data analysis system. The present invention can be used for measuring gas solubility in a natural gas hydrate solution system at different temperature, pressure and salt ion conditions, and exploring influence of different environmental conditions on the gas solubility when hydrate-liquid water biphase equilibrium is achieved. The present invention in characterized in that the structure is simple, the operation is easy, sampling is carried out at a constant pressure to avoid damage to phase equilibrium and dissolution equilibrium of the systems, and a microfilter is used to ensure that a liquid sample taken does not contain hydrate crystals, so that experimental data has a relatively high accuracy.

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.
