ABSTRACT:
A process for determining if intermittent water injection is the best way to remove deposits such as salts from refinery process streams. A water vapor pressure, P1, at stream conditions and a water vapor pressure, Ps, at saturation conditions in the stream, are used to calculate a ratio P1/Ps. If the ratio is less than 0.1 intermittent water washing is preferred. An optimized intermittent injection procedure, frequency, duration, and constraints, is disclosed. Chemical speciation calculations ensure that all accumulated salts are removed, and that an aqueous phase forms downstream of the water injection point having a salt concentration within acceptable limits.
