Slop treatment for offshore disposal using the ATC unit is a concept developed for Chevron by ConstantinConsulting.
Slop treatment for offshore disposal using the ATC unit is a concept developed for Chevron by ConstantinConsulting.
The concept is based on the flow-back water treatment principles while taking advantage of the large volume of the offshore oil rigs storage tanks and on the water recycling capabilities of the ATC unit combined with innovative usage of the filter cartridges.

A full-scale yard pilot test has been performed using for treatment the slop water generated by the tank cleaning activities.

For a land-based operation, the large footprint of the set-up was not a problem but the challenge was to find the right solution capable to perform the treatment offshore.

The dual filter pod used not as solids filtering media but as a semipermeable membrane was a revolutionary approach.

Close control of temperature and differential pressure across the filter allowed the system to work at maximum economic efficiency.

Careful monitoring of the water flow and regular sampling is the main ingredient of the slop water treatment success.
