Petrochemical Process Equipment Cleaned with CO₂

PolarBlast, Inc. has been servicing the industry along the Gulf Coast for more than nine years with our CO₂ blast cleaning services. We have designed our equipment to quickly clean to minimize down time. CO₂ blasting utilizes compressed air to propel dry ice pellets much like a sand blaster uses air to propel sand. We use dry ice pellets in place of sand, soda, or water, because it is completely non-abrasive. After cleaning, the pellets will sublimate, pass from a solid to a gas without becoming a liquid. Therefore, there is no cleaning media residue requiring containment or disposal. This process is not designed to replace sand/soda/water blasting altogether, but is ideal when such processes are detrimental to the surface being cleaned, its surroundings, is an expensive disposal issue, or may pollute the process stream.

CO₂ Blasting can remove residues from:

Surroundings that make CO₂ Blasting ideal:

Rotating Equipment	Running Machinery	Inside process vessels where removing other media would be too time consuming and a costly disposal issue
Electrical equipment	Other workers

Plant Applications:

Boiler Furnaces	Dryers	Motor Windings	Rust removal
CCR Platforms	Electric motors	Generator Windings	Loose Paint removal
Regenerators	Electrical Equipment	Polyethylene Reactors	Styrene Reactors
Coating Removal	Furnace tubes	Pumps	Compressors
Switch gears	Compressor housings	Gas Cycle Compressors	Reformers
Transformers	Tube cleaning	Turbines	Weld seams
Conveyors	Glycol Reactors	Rotating Equipment	Mix Tanks
Cosmetic Cleaning	Descaling equipment

Advantages to CO₂ Blasting:

• No cleaning media to contain, clean up or dispose
• No surface deterioration
• No exposure issues
• Much faster and more thorough than labor and solvent scrubbing
• No possibility of process equipment pollution by solvent cleaners.
