Abstract
An integrated process simultaneously removes the diluent and reduces the TAN, resulting in cost savings from the diluent recovery and increasing the value of the produced heavy crude stream by removing the acids and other contaminants, while reducing the overall energy requirements when compared to performing the two processes separately.
