Special IX Process Meets Rigorous Demands For Additional DI Plant Needed For Major Refinery Expansion

By Cliff Lebowitz

Energy utility engineers for Spain’s recently expanded Cartagena Repsol Refinery have reported successful deployment of a special ion exchange (IX) process that was selected to help provide for demineralized (DI) water needed to increase the refinery’s utility steam production from 110 tons/hr to 400 tons/hr.

The proprietary, packed-column process from Purolite is the final step of a treatment process that is providing conductivity of <0.1 microsiemens/cm for boiler feedwater for the new, award-winning DI plant, which was designed and constructed by SADYT as part of its turnkey, zero discharge project responsibility for all water treatment aspects of the refinery expansion.
