Saving Costs and the Environment

Storage tanks (both fixed and transport) are repositories for invaluable oil and oil-based products that fuel our economy; but once drained also retain unwanted accumulations of petroleum sludge, residue, baked-on asphaltenes, and other hydrocarbons, posing a hazardous and costly clean-up task for tank operators.  Traditional cleaning methods require the use of petroleum products, diesel and/or caustic chemicals as well as worker entry into the tanks for high-pressure spraying and oftentimes manual jackhammering or scrubbing of surfaces.

TerraHydroChem’s non-toxic, fully biodegradable products convert tank sludge and solid bottoms into a flowing liquid, so that personnel can easily and safely pump out the oil and other fluids.

We accomplish this through a simple, highly effective two-step process that applies our proprietary products.  First our solvent gets the heavy sludge, asphalt, and other solids flowing, followed by our super-concentrated proprietary finishing rinse to quickly eliminate LEL’s for entry.  Note that the finishing rinse alone can be used in “white oil” tanks for rapid entry and inspection by eliminating the LEL’s in the tank faster than any other product in the market.

TerraHydroChem’s tank cleaning adds significant value by:

a) Vastly improving the safety by reducing or eliminating the need for manual entry to clean the tank.

b) Significantly reducing the time required to clean the tank (less manpower hours)

c) Greatly reducing the time the tank is out of service, improving operations’ supply chain options.

d) Reducing hazardous waste (tank bottoms contains valuable hydrocarbons that can be reprocessed when flowing, avoiding landfill costs).
