- 1 - Abstract: Hot water is an important component in the recovery or extraction of bitumen and heavy oils. This hot water tends to form emulsions with the oil and when these emulsions are broken by demulsifiers and the oil separates, the remain- ing water retains a black color and cannot be recycled in the process. The black color has been most difficult to remove, but it has now been found that it can quite easily be removed by certain selected adsorbents. These include high ash coal rejects, fly ash from coking gas and red mud.
