摘要： 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.

摘要： The invention discloses a gas hydrate pressure maintaining replacement device and method for in-situ Raman analysis. Comprehensive experiments such as the formation/decomposition/displacement of high-pressure gas hydrates can be realized, and in-situ Raman characterization can be performed. Including reaction kettle system with temperature control unit, pressure control gas supply system, pressure holding system, replacement gas system, sample pre-cooling system, vacuum system and data acquisition and processing system. The device can solve the problem that the Raman peak position of the 512 cage is covered by the Raman peak position of the gas when the high-pressure gas hydrate is characterized in situ in the reaction kettle, at the same time, it solves the problems of sampling difficulties in ex-situ Raman characterization and experimental errors caused by sample transfer.
