In styrene dehydrogenation, one of the process byproducts is CO2, which is a root cause of corrosion in these units. A corrosion inhibitor is commonly used upstream of where active corrosion is taking place. The Nalco Champion PRISM™ program offers proven multi-component corrosion inhibitors, capable of efficiently mitigating corrosion throughout the plant without causing negative impact to the reaction catalysts.
CO2 dissolved in water creates a corrosive environment. Throughout the styrene units, areas where steam condensation takes place are high-risk areas for corrosion. These include the after reactor coolers before the hydrocarbon water separator, overhead condensers where steam condenses, vent gas compressor after cooler area and overhead of the process water stripper.
Nalco Champion provides leading corrosion inhibition technologies to address your plant’s corrosion control challenges. Our technologies include both amine-based neutralizers and non-nitrogen containing filmers in places where nitrogen poisoning might be a concern. Our professional on-site service teams provide regular program monitoring to ensure corrosion inhibitor performance. Our advantages include:
Comprehensive system survey and risk assessment prior to program proposal
Custom-designed program to ensure safety
Proprietary amine blends as well as non-nitrogen containing filmers
