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.
Claims9
An apparatus comprising:
- one or more heaters to heat a blend of bituminous crude oil and diluent to degradation of naphthenic acids in the crude oil;
- one or more reactors to provide sufficient residence time at elevated temperatures for the decomposition reactions to reduce the acid concentrations to reduce total acid number by at least 75% and to simultaneously remove the diluent;
- and
- a distillation column to remove diluent by distillation.
