Custom Anodically Protected Sulfuric Acid Cooler With High Heat Transfer Efficiency

stands at the forefront of engineering and delivering advanced heat transfer solutions tailored to the chemical processing sector. Among its specialized offerings, the Anode Protection Sulfuric Acid Cooler represents a cornerstone technology for ensuring safety, efficiency, and longevity in modern sulfuric acid plants.

The Anode Protection Sulfuric Acid Cooler is a shell-and-tube heat exchanger purpose-built to cool concentrated sulfuric acid—typically ranging from 93% to 99%—within the drying and absorption stages of contact process facilities. The challenge is straightforward: hot concentrated acid is aggressively corrosive and quickly degrades standard construction materials. The solution lies in anodic protection, an electrochemical technique that maintains stainless steel in a passive, non-corroding state throughout operation.

The operating principle centers on anodic protection, which involves polarizing stainless steel components (the anode) to a specific electrical potential within their "passive range." This is achieved through a cathodic system—typically comprising elongated cathodes running through the shell or pin cathodes inserted in nozzles—working in concert with a reference electrode and a potentiostat that regulates the DC power supply.

Jiangsu Carpe Diem Ocean Equipment Co., Ltd. delivers these high-integrity cooling solutions with a clear commitment: providing clients with durable, low-maintenance equipment engineered to meet the exacting demands of large-scale sulfuric acid production—and built to perform reliably year after year.
