GE unveils new corrosion protection technology for refinery steam systems

04.15.2013  | 

The new technology is cost-effective, according to GE officials, and will provide corrosion protection of refinery boiler and steam-condensate systems while minimizing the potential for formation of corrosive amine salts in crude distillation units where utility steam is used in crude processing.

GE on Monday announced a new corrosion protection technology specifically designed for refinery boiler and steam condensate systems. 

The company says its Steamate low salt amine (LSA) product series offers enhanced steam-side corrosion protection while providing greater reliability to the crude unit distillation process.

The Steamate LSA product series is made up of proprietary blends of volatile amines in combination with GE’s unique polyamine surface corrosion inhibitor, according to the company.

The new technology is cost-effective, according to GE officials, and will provide corrosion protection of refinery boiler and steam-condensate systems while minimizing the potential for formation of corrosive amine salts in crude distillation units where utility steam is used in crude processing.

Corrosion can threaten the reliability and safety of critical refinery equipment, raise maintenance costs, reduce process runtime and jeopardize product quality. In addition, corrosion control is becoming more important as refiners around the world turn to lower-cost "opportunity" crude oil feedstocks and often work to maximize middle distillate production.

The GE Steamate LSA series offers a powerful dual corrosion protection feature with a neutralizing amine package in combination with the polyamine surface corrosion inhibitor to provide enhanced corrosion protection in areas that have historically plagued refiners, such as reboilers and users of low-pressure flashed steam.

More importantly, the refiner will not be restricted in operation because of crude unit distillation concerns around corrosive and unwanted amines being introduced from the utility steam treatment.

“GE’s new Steamate LSA technology will provide increased reliability and cost savings through the reduced potential for corrosion failures and production interruptions in boiler, steam condensate and crude distillation units,” said Ava Drayton-Elder, water services global product management leader for GE Power & Water.

Steamate LSA is ideal for refineries, as it offers advanced corrosion protection technology.”

Utilizing the latest version of GE’s LoSalt simulator software, the proven neutralizing amines in Steamate LSA were chosen for both optimum cost performance in the boiler and steam system and compatibility with the refinery crude distillation process.

Specifically, they were selected to minimize the potential for formation of corrosive chloride salt deposits throughout the refining process where boiler steam is used in crude processing.

Hello George. Thank you for your interest in our new Steamate LSA series of boiler corrosion inhibitors. The components of this amine series have been selected based on multiple performance criteria. The hydrothermal decomposition behavior of volatile and surface-adsorbed corrosion inhibitors in a boiler system is a complex function of steam and water temperatures, residence time, the inherent stability of the compounds, and other factors. A detailed dicussion of this behavior is beyond the scope of this forum. Suffice it to say that at the temperatures, pressures and residence times typical of refinery boiler operations, the components of the Steamate LSA series exhibit excellent thermal stability and retain their functionality as corrosion inhibitors.

What does the amine break down as?? Ammonia & nitrogen or what??
