针对目前油田深床过滤器清洗效率低、清洗不彻底的现状 ,采用大功率超声波清洗流程及装置对核桃壳、纤维球和石英砂等 3种滤料进行了清洗试验 ,确定了最佳超声波频率为 4 0kHz ,每种滤料只需清洗 7min便可使水质达标。超声波清洗 1次的耗电量为 0 4 8~ 0 5 6kW·h ,是机械搅拌清洗所耗电量 (1 33~ 2 0kW·h)的 2 8%~ 36 % ;是水力搓洗所耗电量 (2 5~ 3 13kW·h)的 18%~ 19%。大功率超声波清洗具有清洗效率高、效果好、省时省电等特点。  相似文献

Studies on the development and introduction of a dynamic pulsing filter in production of base oils and solid waxes are continuing. The results of pilot tests of the filter and subsequent calculations demonstrated the high effectiveness of its addition in separation of wax suspensions. __________ Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 2, pp. 12–15, March–April, 2007.  相似文献

In this article, a fluidized bed apparatus was used to study the effect of operating conditions on the yield of diesel oil. The calcined dolomite was also used as an additive to produce more diesel oil. The addition of calcined olivine had also a positive effect on reducing weight loss, because, using a catalyst, the rate of reactions increased at a constant temperature, and, the fuel was decomposed more rapidly into lighter components. At a reaction time of 8?min, total weight loss for 5%, 7%, and 10% calcined olivine was respectively 12.1%, 9.9%, and 8.0%.  相似文献
