Sulfuric acid concentration

ExtrAcidTM system for sulfuric acid (H2SO4) concentration

Based on Wilk-Graphite’s SIC block heat exchanger.

This patented system concentrates sulfuric acid (H2SO4) 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. The system is supplied worldwide as a ready-to-operate frame construction.

SCU means Sulphuric acid Concentration Unit.


• From 20 % to 96
• 300 °C & FV / 16 bar
