| Abstract: |
| In order to promote the rapid defoaming of heavy oil in separators, the mechanical defoaming technology for an oilfield was studied. The separation effect and foam change in separator under different guide plate parameters were simulated with Fluent. The defoaming effect of different types of metal structured packing and defoamers as well as a combination of both were tested by using the high pressure dissolved gas defoaming test system. The results show that the separation efficiency and foam coalescence effect are better when the angle is 45° and the placement distance of guide plate has little effect on separation efficiency and defoaming effect. With the increase of the height of defoaming packing, the defoaming effect increases. To summarise, the optimal placement angle of the inlet guide plate in separator is 45°, SM25012 cm corrugated packing was selected as the optimal mechanical defoaming component; Mechanical foaming method can meet the demand of defoaming in actual production, and when better defoaming effect is required, mechanical defoaming method and chemical defoamer can be combined. |
