System and method for measuring gas solubility at normal pressure and temperature

Abstract

The invention discloses a measuring system for measuring the solubility of a gas in conducting fluid at normal pressure and temperature, comprising a data acquisition device, a gas measuring device and a temperature control device. The measuring system is characterized in that: the gas measuring device comprises a sample chamber, a demarcating chamber, a temperature control mechanism and a magnetic stirring mechanism; the data acquisition device comprises a first gas pressure sensor, a second gas pressure sensor and an upper computer 11; an end face of the sample chamber is connected with thefirst gas pressure sensor through a three-way connection; an end face of the demarcating chamber is connected with the second gas pressure sensor through a four-way connection; a side end of the three-way connection is connected with a side end of the four-way connection through a first ball valve, the other side end of the four-way connection is connected with a second ball valve; the first ballvalve, the second ball valve, the three-way connection and the four-way connection are connected through stainless steel tubes. The measuring system of the invention can perform stirring when degassing and gas dissolution are performed on a to-be-measured material, thereby accelerating the efficiency of degassing and gas dissolution.

Description

technical field [0001] The invention relates to the field of measuring the solubility of gas in liquid, in particular to a system and method for measuring the solubility of gas at normal temperature and pressure. Background technique [0002] The magnetic fluid angular velocity sensor is a new type of angular velocity sensor. This angular velocity sensor has no solid moving parts, low mechanical wear, and has the characteristics of high reliability, high strength and long life; the ring structure design of the magnetic fluid gyroscope greatly reduces In order to be sensitive to vibration acceleration and quadrature axis angular velocity, the magnetic fluid in the MHD sensor is a conductive fluid, and the working mode of the sensor is mainly to generate signals by cutting the magnetic induction lines of the conductive fluid. [0003] The co-flow in which gas and liquid are mixed together is called gas-liquid two-phase flow. Gas-liquid two-phase flow exists widely in nature, s...

Problems solved by technology

[0005] At present, there are few studies on the solubility of gas in liquid under low pressure environment. The more common gas solubility measurement is mainly in the high pressure range of 1MPa to hundreds of MPa. For the gas solubility measurement in the low pressure range of 0-0.1MPa relatively rare
