  • Chloride Management Program

    Because properly monitoring a Cl bed is crucial for maintaining an effective Cl treater, every system we install includes online monitoring. Once a system is installed, we teach and implement our Chloride Management Program (CMP). Our CMP is far more than simply pulling a Draeger tube once a week; it's a culture shift within a refinery. Refineries utilize capital investments in Cl treaters to protect their downstream equipment, keep product in spec, and mitigate any pipe corrosion to protect everyone inside the unit.

We conduct onsite training, Cl surveys, and tests for organic chlorides. Maintaining an effective Cl treater is vital to achieving all operational goals.

We understand that no two Cl treaters or sulfur guards are the same, and we offer custom-made absorbent systems.

The maintenance of a chloride removal Vari-Zeo System from CLS Industrial Purification is the easiest and most cost-effective of any material available.
