Naturgy Generación has upgraded the cooling system at its combined-cycle natural gas power plant in Puerto de Sagunto, Spain. The new cooling system — developed and installed by Spig S.p.A, part of Babcock & Wilcox’s B&W Environmental segment — is designed to reduce water usage and reliance on chemicals for water treatment.

The recently completed project included removal of some of the plant’s existing cooling tower components before Spig installed a cooling tower with fiberglass-reinforced plastic structure.

According to B&W, the new cooling tower is designed to protect against corrosion and wear from saltwater used for cooling. Because the seawater cooling towers decrease or eliminate the need for desalination and processing of cooling water, they help safeguard marine ecosystems and reduce the overall environmental impact, says the company.
