SUEZ launches new programme

Chemical processing plants, power plants, and refineries that use seawater for cooling face an ongoing battle against deposition and fouling in their condensers and heat exchangers, which reduces efficiency and can lead to costly downtime.

SUEZ’s OptiSea* uses a combination of chemical treatment and digital monitoring to prevent deposition and fouling in cooling systems that rely on seawater. SUEZ believes that OptiSea will reduce total cost of operation (TCO) for customers by maximising cycles of concentration and optimising chemical usage, with performance assurance through real-time deposition monitoring.

“Operators have expressed a strong desire for a technology that optimises control of deposition and fouling through performance monitoring,” said Hoshang Subawalla, Executive Vice President of Chemical & Monitoring Solutions for SUEZ – Water Technologies & Solutions. “OptiSea allows customers to visualise risk in real-time, reduce chemical usage and handling, improve control of suspended solids, and improve the environmental profile of discharge, while maximising cycles of concentration and minimising thermal pollution.”

Using seawater in cooling systems presents special challenges. The composition of seawater differs from place to place across the globe, and there are wide variations in the type and quantity of suspended solids. Macrofouling organisms in the water have a high growth rate, and seawater tends to have a high ionic strength. Taken together, these reasons mean that seawater cooling systems require specialised modelling, treatment, and monitoring systems to ensure peak production and optimised efficiencies, especially plate-and-frame heat exchangers.

OptiSea effectively models high ionic strength seawater, provides deposition and suspended solids control, and monitors deposition accumulation and heat transfer performance in realtime, while optimising chemical usage with three layers of supervisory monitoring and control protection.

“OptiSea is the only program available in the industry that correctly models seawater deposition risk to optimise chemical treatment, offers new, non-phosphorus chemistry, and effectively monitors chemical feed and deposition online and in real-time for performance assurance,” said Jim Green, Global Product Marketing Leader for SUEZ – Water Technologies & Solutions. “OptiSea is ideal for the many plant operators we’ve talked to that want to maximise cycles of concentration or optimise performance and costs at 1.3 cycles.”
