Solving Energy Industries Biofouling Issues
The CTE system is typically used for small to medium production capacities, while PPE system is typically used for larger production capacities of sodium hypochlorite. The CTE systems have the distinct advantage of being self and easy to maintain for smaller capacity systems and especially for use for use on offshore platforms and shipboard units where the logistic and cost of supplying and dealing with chemicals is high.
Parallel Plate Electrolyzers are constructed of bipolar electrode stack and typically present the most cost effective solution for providing hypochlorite when the capacity exceeds 30 Kg/hr. even though they require acid washing as the plant foot print is typically smaller, cost per kilogram is lower, power consumption per kilogram of equivalent chlorine is lower and there are few potential leak points. This is typically the preferred technology for power plants, desalination and other large industrial seawater cooling applications. As the overall cost of ownership is typically lower due to lower capital cost and power consumption.
MPC Electrolyzers are constructed of a monopolar electrode stack and are typically configured for smaller capacities as the footprint becomes quite large for the larger capacity systems. However as they have a clear acrylic cover certain owners and operators prefer them as they can easily tell when acid cleaning is required and they like the serviceability aspects as the cells can easily be replaced by the maintenance team without the assistance of service specialist. Also due to the fact it is monopolar each individual cell operates at a lower voltage and is safer than the bipolar type systems of CTE and PPE. The MPC cells are designed to be directly interchangeable with the DeNora Sanilec Cells.
