英文摘要	To further investigate the influence of internal components on separation characteristics of a gas-liquid separation unit in a new skid-mounted device with gas-liquid separation and flash distillation, based on standardk-Ε turbulent model and Eulerian/Eulerian approach, the CFD method was performed to establish a numerical simulation model of flow characteristic on the separation chamber to improve it's simulation efficiency. The simulation results were compared with the experimental measurements to verify the accuracy of the model, and the internal components' structural parameters were optimized. The analysis of the influence of communicating pipes, demister, deflector, baffle plate on separation efficiency, showed that the number and location of communicating pipes can lead the fluid in the separation chamber disturbance. With the thickness of the demister increasing, the trapping effect of the droplets is enhanced, while the diameter of which has little influence upon separation efficiency. The deflector mainly affects the velocity of the inlet fluid, when it's depth and angle changed, the separation ability changed significantly. The baffle, mainly rectifing the fliud flow, has little effect on the separation effect. Through the optimization of internal components' structure on the separation chamber, liquid in separation chamber can be discharged smoothly into the cylinder, and also avoid the cylinder air lock when the number of communicating pipes are more than two and distribute in the liquid and gas regions of the separation chamber, respectively. The separation efficiency of gas-liquid separation unit will reach 98% when the demister at a thickness of 60 mm to 120 mm. When the deflector at an angle of 90° to 135° and a depth of 385 mm to 647 mm, the slow flow in liquid regions of separation chamber leads to the drainage smooth, and the separation efficiency can be improved. The above results will provide theoretical guidance for the optimization and design of structural parameters on gas-liquid separation unit in a new skid-mounted device with gas-liquid separation and flash distillation.
