Abstract: An internal circulation type clathrate hydrate-based cold storage system and method are provided in the field of industrial refrigeration. The internal circulation type clathrate hydrate-based cold storage system includes a water chilling unit, a hydrate-based cold storage tank, a gas disturbance device, a concentration measurement system, a heat exchange system, a direct-current power supply and circuit control system, and a system monitoring device. The water chilling unit provides a secondary refrigerant at a low temperature. The secondary refrigerant flows through an evaporator coil in the hydrate-based cold storage tank for a heat exchange. The gas disturbance device induces hydrate nucleation. The concentration measurement system monitors a concentration of a hydrate solution in real time. The heat exchange system is equipped with a finned tube heat exchanger with a fan. The system monitoring device monitors a state change of the system in real time through a plurality of temperature-pressure sensor modules.

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.
