Energy Recovery in Waste Management

As societies around the world adopt greener practices, the substantial shift in behavior puts pressure on many industries to follow suit. The industrial sector has responded by developing processes that turn industrial and municipal waste into reusable energy. Backed by more than 20 years of experience in the specialty polymers business, Solvay’s highly effective corrosion prevention solutions offer a high performing alternative to protect heat exchangers and stacks, effectively extend the service life of chimneys and deliver cost benefits for power plants.

Solvay’s highly effective corrosion prevention solutions offer a high performing alternative to protect heat exchangers and stacks.

A Better Alternative for Corrosion Prevention

Our high-end specialty polymer linings are formulated to provide a robust and flexible prevention alternative to specialty alloys, the current market standard. These products stand up to the corrosive environment created when Waste to Energy (WtE) plants burn waste to produce various forms of energy a process that generates a highly aggressive chemical and temperature environment within the plant’s chimney stacks. Typically, plants use flue gas desulphurization (FGD) units to abate dangerous sulfur dioxide gas emissions. These FGD units typically contain very corrosive components such as SO2 /SO3, HCI, NH3 and HF.
