The NATCO ELECTRO-YNAMIC DESALTER electrostatic desalting technology provides multiple phases of electrostatic mixing, coalescing, and settling in a single vessel, delivering nearly 100% salt and dehydration efficiency. The technology provides two-staged desalting efficiency without the excessive capital investments or space requirements common to conventional systems.

Comprising five proven Schlumberger process technologies, the NATCO ELECTRO-DYNAMIC DESALTER technology provides the refining industry with one of the first electrostatic desalting innovations in more than a decade.

Increase operating efficiency while reducing operational expenses
        - Under a variety of conditions, the NATCO ELECTRO-DYNAMIC DESALTER technology can
        - Retrofit your single-stage system to two-stage performance
        - Increase the levels of salt removal over any other single-vessel process
        - Double the salt removal capacity of two-stage systems
        - Reduce initial capital costs for new installations
        - Allow higher inlet water cuts during upset conditions while maintaining specified effluent requirements
        - Improve effluent water quality
        - Improve operational flexibility by handling a wide range of feedstocks
        - Decrease chemical consumption
        - Improve mixing efficiency
        - Reduce washwater requirements
        - Require less space
        - Provie improved dehydration capabilities.

Five steps to successful desalting
        1. NATCO DUAL POLARITY electrostatic treater—applies a high-gradient, sustained DC field between pairs of electrodes while maintaining an AC field between the electrodes and oil/water interface
             - Results: significant improvements compared with AC dehydration
        2. Composite electrodes—obtains a progressive electrical field
             - Results: coalescence of the smallest of water droplets while eliminating sustained arcing due to highly conductive emulsions

        3. LRC-II smart interface—regulates the flow of electrical current and provides self-adjusting electrical power levels for optimized electrostatic coalescence
             - Results: optimal salt removal over a wide range of feed stock materials
        4. Countercurrent dilution water process—increases contact between dilution water, produced water, and particulate
             - Results: improved crude desalting using less washwater
        5. Electrodynamic mixing process—provides multistage contact
             - Results: near-100% mixing efficiencies while enabling reduced demulsifier chemical consumption
