Sour Water Strippers perform a critical and heavy load function in the refinery. As a result, given the increase in ‘sour’ crudes processing, overloading happens in daily operation at different times. Therefore, at Turnarounds, decontamination and cleaning of the Sour Water Stripper is essential, to provide optimum performance upon restart.

Vapour Phase decontamination with CORE CLEAN VP1 can provide a gas-free Stripper in less than 24 hours. Where experience and operating feedback indicates that hard inorganic deposits require removal from the Stripper circuit, CORE can provide a multi-stage procedure for the Stripper and Reboilers. This will remove any hydrocarbons, then remove all inorganic (scale) deposition. Finally, CORE will passivate the clean metal, before return to service.

If H2S is considered an issue, CORE would recommend a close-loop Oxidation rinse as part of either washing or vapour phase approach.
