Heat Exchanger Systems

Clark Solutions was recently commissioned to design and engineer heat exchangers for a major mining company that incorporates sulfuric acid synthesis into its production scale. The request specifically involved replacing exchangers used in the acid cooling process.

The need arose due to difficulties in maintaining and repairing the existing equipment, which had been in operation for a long time.

With its expertise in engineering, project management, and supplier coordination, Clark Solutions delivered state-of-the-art technology and extensive know-how tailored to this application.

The Challenge:

Hot sulfuric acid poses significant operational risks. Equipment exposed to it can degrade, contaminate the system with corrosion by-products, cause leaks, and may suffer catastrophic failures if not properly protected with an electrochemical system.

To address this, Clark Solutions designed new heat exchangers and provided two corrosion protection options:

• Anodic protection
• Construction in CSX™ alloy

CSX™ Alloy Piping

Anodic protection is a well-established technology in the industry. It applies an electrical current to the equipment, shifting its electrode potential to a passivated state, making it resistant to electrochemical attack. This system offers multiple advantages, though it also presents certain challenges.

Alternatively, the CSX™ alloy is a high-performance metallic material developed for extreme corrosion resistance. Its composition includes chromium and silicon, which strongly bond with oxygen to form stable oxides and hydroxides. These compounds rapidly deposit across the surface, forming a protective passivation layer.
