Another 7.5tph 176-tube Sulfonator Successfully Commissioned – Delivering Quality at Scale
May 14, 2026We recently completed the commissioning of another large-scale 176-tube 7.5tph sulphonation reactor at a major domestic surfactant plant. So far, Weixian has supplied totally 5 sets of reactor or complete plant with 7.5tph or 8tph capacity.
Key performance metrics achieved:
🔹 Active matter: 96.83%
🔹 Free oil: 1.0 wt%
🔹 Sulfuric acid: 0.8 wt%
🔹 Color: 16 Klett
Consistent, high-quality sulfonation at industrial scale.
