SEPARATION OF TAILINGS THAT INCLUDE ASPHALTENES |
摘要 |
<p>Various systems and methods are described that can be used as part of a process to separate bitumen from oil sands. The process may include adding a hydrocarbon solvent to a bitumen containing extract. The tailings from this process may contain a significant amount of solvent. The solvent may be recovered from the tailings with a tailings solvent recovery unit that utilizes negative pressure to significantly reduce the cost of the process in comparison to a conventional steam stripping unit. In one embodiment, the tailings may also separated prior to entering the tailings solvent recovery unit with a gravity separation apparatus or a cyclonic separation apparatus, such as a hydrocyclone.</p> |
