Based on Wilk-Graphites SIC block heat exchanger. This patented system concentrates sulfuric acid (H 2 SO 4) from any concentration up to 99.3%. It halves the investment costs (CAPEX) and the required footprint. At the same time, the ongoing operating costs (OPEX) are also reduced by producing process steam up to 10 bar as a by-product.
Sulfuric Acid Process KBRKBR offers the fully corrosion-resistant sulfuric acid high-concentration SAVACO ®-HT heat exchanger, TO-HeX, allowing up to 98 wt% H2SO4 with a proven lifetime of more than 30 years, which is a unique offering to the market and the most advanced technical solution available for this application.

Tantalum Heat Exchangers
Sulfuric Acid Concentrator Anti-corrosive Concentrator The sulfuric acid concentrator is equipped with a double seal:carbon steel tube sheet and PTFE tube sheet. All silicon carbide tubes pass through the carbon steel tube sheet, and we use special sealing rings that are able to withstand high temperatures and pressure on the steam side.
With the high-temperature treatment of sulfuric acid using the Pfaudler HTX Heat Exchanger, Pfaudler has developed a special thermal oil heated glass-lined steel heat exchanger which allows for acid temperatures up to 250°C.
