Study On A Phase Equilibrium Apparatus Of Salt Solution And Air

With the present society the importance of environmental protection and energy efficiency, air source heat pump technology and the development of desiccant air conditioning technology has been relatively large concern, which involved more extensive air and salt solution equilibrium, the thermodynamic properties of increasingly attracted attention. The experiment data of the salt solution and air equilibrium have not been reported in the literature. Gas chromatography technology has simple, easy to operate etc, characteristics. With the mature development of chromatographic techniques, gas chromatography has been able to more effectively detect trace moisture. In this paper, propose the use of chromatography direct determination of salt solution and air equilibrium, design and build vapor-liquid equilibrium experimental device.A new measurement system for VLE properties of high accuracy was developed by vapor circulation method. It consists of a high precision temperature measuring system (within253K to368K, measurement uncertainty less than±10mK), high precision pressure measuring system (measurement range is0-150kPa, measurement accuracy for0.075%), high precision temperature slot (253K to368K), vacuum system and so on.For the lithium and air vapor-liquid equilibrium experimental data is certain test, but there are still inadequate, this paper is mainly for the determination of high temperature experiments, the low temperature area has not been carried out work, and has not been established the thermodynamic model to describe these data.
