Treatments for Pyrophoric Iron
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 can take place that may cause injury to personnel and catastrophic damage to equipment.
We create a custom plan for each unique tower or column with information such as column design, feedstock, history of the unit, and utility availability.
We use Entry Safe™ OX oxidiser to neutralise the iron sulphides or elemental iron and sulphur oxides. The solution may be buffered to a pH of about 9 with di sodium phosphate or monosodium phosphate. A chemical additive that provides a quantitative measure of reaction completion also may be added to the treatment solution.
