Method for Treating Oil Refinery Equipment for Pyrophoric Iron Sulfide Using Ozonated Water

摘要

Pyrophoric material such as iron sulfide is frequently found in refinery equipment. When the equipment is opened to the atmosphere for maintenance, an exothermic reaction may take place that can cause catastrophic damage. A process for treating pyrophoric material uses ozonated water to oxidize iron sulfide to iron oxide. The heat produced by this exothermic reaction is absorbed by the ozonated water.
