APPLICATION
1. It's a very excellent and ideal product for high temperature and steam applications,
such as secondary reformers in ammonia processing, where leached silica will coat
downstream equipment or foul the catalyst bed.
2. It's suitable for applications in olefin processes, such as ethylene dryers, where there's the polymerization problem.
