Pharmaceutical

API plant brine/steam system replaced

Severe corrosion of reactors, heat exchangers and pipelines from a brine/water/steam system led to a full system replacement and the loss of a batch of pharmaceutical intermediates. After refilling with ET-4, the corrosion issue was resolved and the system has run without corrosion since.

Glycol Conversion

500-tonne glycol system converted to ET-4

A glycol solution operating at −20 to 100°C suffered severe high-temperature corrosion within three months. Replaced with 50% ET-4 across a 500-tonne system, it has run without corrosion since the change.

Cold Storage

40,000-tonne facility, indirect system

A 40,000-tonne cold-storage facility uses an integrated primary refrigerant plus ET-4 secondary loop. The indirect design is safer and more environmentally friendly, and corrosion has been eliminated.

Tested by the Institute of Metals, Chinese Academy of Sciences

Anti-corrosion performance for our formulations has been assessed by the Institute of Metals, Chinese Academy of Sciences, with measured corrosion rates on carbon steel, stainless steel and copper coming in well inside national standard limits, alongside standard test methods equivalent to ASTM G31 and ASTM G1. We can share the relevant test report for the grade you’re evaluating.
