  1. What is decontamination?

    Decontamination is a process for making refinery equipment safe for personnel entry.

    To meet this goal after decontamination equipment must be:-

    • Non-pyrophoric
    • H2S free
    • Benzene free
    • Explosive gases (LEL’s) free

    This is achieved by:-

    • De-oiling via solvency and surfactancy
    • Sulfide oxidation – in all areas of the equipment
    • Degassing – LEL from water, oil and vapor
    • Benzene control – putting the benzene where you want it
    • Sludge reduction
    • Wastewaster conditioning - if you can’t get rid of the wastes generated quickly decontamination has not taken place
