 The effect of oil temperature on the oil-gas separation characteristics of Teflon-AF/ceramic composite membrane module was studied. When the temperature increased from 40 °C to 60 °C, the Teflon-AF/ceramic composite membrane could not only shorten the equilibrium time of all the fault gases, but also remarkably enhance the equilibrium concentration of H2 by about 30%, CO by about 40%, and hydrocarbons by about 10%, indicating that the proper oil temperature can improve the degassing efficacy of this membrane. A temperature-controllable degassing machine has been designed based on the he experimental results and on which, the oil-gas equilibrium time reduced from 5h to 1.5h and the monitoring data obtained was more precise and repeatable. The machine is quite applicable to the dissolved gas-in-oil monitoring system.
