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 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: A carbon dioxide sequestration method based on reservoir wettability optimization design and layered regulation, which proposes the following four schemes for a carbon dioxide sequestration process: a carbon dioxide sequestration process seepage characteristics simulation scheme, a reservoir wettability optimization design scheme, a reservoir wettability regulation scheme and a carbon dioxide sequestration well layout design scheme. Firstly, a quantitative relation between the contact angle and the carbon dioxide seepage characteristics of a reservoir is obtained by relevant methods, a large scale simulator is used to quantitatively simulate the influence of the contact angle distribution of the reservoir on carbon dioxide sequestration, and layered optimization design and regulation of reservoir wettability are carried out according to the simulation results; and a well layout mode of “using one well for multiple purposes—using two wells in conjunction—adopting a network layout” is used to improve the flexibility of well layout.
