This project explores improved methods of processing that would ultimately increase the recovery of oil (bitumen) by removing more of the salty water droplets earlier in the process. These improvements also aim to protect the multi-million dollar process vessels used to upgrade the bitumen into processable crude later in the process.****We are considering the mechanism of sweep flocculation, where the water droplets do not have to coalesce - they simply form a loosely connected agglomerate which captures clays and fine water drops as it settles through the diluted bitumen froth. You might think of this as a moving filter, settling through the diluted bitumen froth.****If this mechanism can be cleanly identified, it would give us a better understanding of the separation process and open the doors to continued process improvement, longer process plant life, and safer operations.****

该项目探索了改进的加工方法，通过在加工过程的早期去除更多的盐水滴，最终提高石油（沥青）的回收率。这些改进还旨在保护数百万美元的加工船，这些船用于在加工过程中将沥青升级为可加工的原油。我们考虑的是扫掠絮凝的机理，其中水滴不必聚结-它们只是形成松散连接的团聚体，当其通过稀释的沥青泡沫沉降时，团聚体捕获粘土和细水滴。你可能会认为这是一个移动的过滤器，通过稀释的沥青泡沫沉降。如果这种机制可以明确地识别出来，它将使我们更好地了解分离过程，并为持续的工艺改进、更长的工艺设备寿命和更安全的操作打开大门。
