Alfa Laval - Reactor temperature controller in green chemicals production

Reactor temperature controller in green chemicals production

A green chemicals plant in France decided to replace a failed heat exchanger with Alfa Laval DuroShell.

DATE 2019-10-14

A green chemicals plant in France endured longstanding problems with a heat exchanger used for controlling reactor temperature. Sudden steam injections in the reactor resulted in rapid temperature and pressure changes, which in turn caused fatigue in the heat exchanger. The company's engineers decided to replace the failed heat exchanger with a DuroShell.

With its unique design, DuroShell secures fatigue resistance up to five times higher than other plate-and-shell heat exchangers. The high thermal transfer and low hold-up volume let DuroShell regulate temperatures quickly and accurately, which is important for both product quality and process yield.
