摘要
金属微填料旋流消泡器将旋流离心气液分离与填料机械破碎消泡相结合,应用于高温高压的石油物系——丙烷-脱油沥青泡沫体系的消泡试验研究.研究表明,利用自制的金属微填料旋流消泡器,无需加入消泡剂,能够达到100％的消泡效果.推荐的实验条件是,金属微填料填充密度190 ～210 g/L,泡沫流量3.0～4.0 kg/h,金属丝径在20μm以下,在相同当量直径下,不规则横截面金属丝消泡效果优于规则横截面,但在一定范围存在一个优化的几何尺寸.
Metalic micro-filler swirling defoamer which combines the advantages of cyclone centrifugal separation and mechanical crushing is applied to defoam a kind of petroleum foam system at high temperature and pressure.The results show that the 100％ defoaming effect can be achieved by using patented metalic micro-filler swirling defoamer without additional defoaming agent.The testing parameters are recommended as follows：about 190-210 g· L-1 of packing density of micro-filler,3.0-4.0 kg·h-1 of flow rate and below 20 μm of diameter of the metal.At the same equivalent diameter,for the defoaming rate of metal,irregular cross-section is better than the regular one,and at a certain range,there will be an optimal size.
