This November 3–5, CRU Sulphur + Sulphuric Acid 2025 comes to The Woodlands, TX, and CG Thermal will be there to discuss your harsh and corrosive process streams and solutions in high-temperature. Whether you’re focused on sulfuric acid regeneration, dilution, or gas-to-gas heat recovery, we bring expertise that extends equipment life and lowers operating costs.
Among the technologies we’ll be highlighting is the AirBTU VPRR High-Temperature Gas-to-Gas Recuperator, delivering reliable performance up to 1200°C. If you’re attending, stop by and connect with us. Let’s talk about how CG Thermal can help you reduce downtime, improve efficiency, and extend the life of your assets.
Let us help you optimize your plant!
“Join us in Texas! Sulphur + Sulphuric Acid continues to be an essential annual forum for the global sulphur and acid community to learn, connect and do business. Knowledge sharing is at the event’s core: via the respected dual-streamed technical programme, and the connections made with industry experts and solution providers attending.
In 2025, you can expect an expanded market outlooks agenda, including expert insights from CRU’s analysis teams on major supply and demand markets, including sulphur and sulphuric acid, plus additional industry updates from key players from across the supply chain.”
We hope to see you there!
High-Temperature Engineered Solutions
Unique customers and process streams require High-Temperature Engineered Solutions, with an emphasis on custom-tailored designs. Utilizing temperature and flow mapping, our engineering team develops a digital twin of the ideal unit for every individual stream to allow for accurate, true-to-life modeling. The result is industry-leading design solutions to eliminate thermal stress and corrosion common in these environments, offering improved reliability.
AirBTU VPRR: High Temperature Energy Capture
Are you looking to improve the reliability of your high-temperature heat transfer equipment? By integrating our AirBTU VPRR heat transfer solution, industry professionals can avoid common pitfalls and “design in” reliability and efficiency. The AirBTU VPRR is designed to:
- Avoid cold-end corrosion. The introduction of low-temperature air can result in cold spots within a recuperator, causing condensation of some constituents of the process gas stream. The resulting reaction between this corrosive condensate and the heat exchanger surface is commonly referred to as cold-end corrosion. This destructive mechanism is “designed out” of the AirBTU VPRR, making it the ideal Heat Exchanger for Sulfuric Acid Applications.
- Eliminate stress failures. Temperature gradients across the tube bundle can lead to uneven stress concentrations at the tube-to-tube-sheet connections. These result in tubesheet failures with subsequent losses in production and costly repairs. We design in uniformity to eliminate this failure mode.
- Reduce pressure drops. Our VPRR features a proprietary design that reduces pressure drops for the best energy efficiency.
- Maximize thermal efficiency. Flow dynamics modeling is used to evaluate tube layouts and pass arrangements to create a symmetric design with optimal film coefficients and overall heat transfer rate. The resulting design requires less surface area and minimizes material and fabrication costs.
- Minimize maintenance downtime. In addition to minimizing failures caused by cold end corrosion and uneven mechanical stresses, we can “design-out” the potential for fouling.
