DEVICE AND METHOD FOR MEASURING GAS SOLUBILITY IN NATURAL GAS HYDRATE SOLUTION SYSTEM

摘要

A device and a method for measuring the gas solubility in a natural gas hydrate solution system. The measurement device mainly includes a reaction system, a sampling system and a data analysis system. According to the measurement device, the gas solubility in a natural gas hydrate solution system can be measured under different temperature, pressure, and salt ion conditions, and the influence of different environmental conditions on the gas solubility is explored when two phases of hydrate and liquid water are in equilibrium. The measurement device has a simple structure and is easy to operate. By using an electric pump (4) and a buffer tank (7) with a piston (8), sampling can be achieved under a constant pressure, avoiding sampling damage to the phase balance and dissolution balance of the system, and a microfilter (22) is used to ensure that there are no hydrate crystals in the liquid sample taken, such that the experimental data has a relatively high accuracy.
