Equipment Data Sheets
STANDARD FRAC TANKS
DHI provides customers with a variety of tank styles for applications in different climates and purposes. Tanks are lined with epoxy to provide resistance against corrosion from most completion fluids and well effluent.
The design criteria of DHI’s frac tanks are in accordance with API-12F guidelines, which stipulate base ASTM A36/36M steel plate.
FRAC TANK VARIANTS
500 BBL & 600 BBL
Vapor tight versions for emission control
Insulated (for arctic climate conditions)
DHI has a special version designed for acid storage with a vinyl ester lining
Standard 500 BBL Frac Tank
FLOWBACK TANKS
The DHI portable flowback tank combines safety and functionality. The flowback tank has front and rear dual-entry gas diffusion barrels.
The full-length walkway permits easy inspection and sampling of fluids and has dual exit paths.
The tank’s capacity is 461 barrels.
APPLICATIONS & BENEFITS
Flowback operations
Gas diffusion of liquid solid gas mixtures under pressure
High capacity diffusion barrels built to reduce erosion rates
Safe walkway for easy access to inspect flowback effluent
High capacity diffusion barrels built to reduce erosion rates
Safe walkway for easy access to inspect flowback fluid
Front and rear access provides a safer two-way exit path
Flowback tank with side walkway
ACID TANKS
DHI’s acid tanks provide customers with a solution for onsite storage of acid and other corrosive fluids. The tanks are a 500-bbl, single-compartment unit suitable for use with HCl up to a concentration of 32%.
The tank incorporates a vinyl ester lining specifically formulated for high acid resistance and longevity.
Valve components and fittings are all acid specification materials.

OIL SKIM TANKS
Oil skimmers work on the principal that oil floats on production water. Oil is collected at the top of the tank and is discharged from a stand pipe port that removes oil from a raised skimmer bucket.
Water is separated by gravity and rotational forces.

CONTINUOUS WALKWAY TANKS
DHI has enhanced storage tanks that have a built-in frontal walkway that permits field technicians to walk along the tanks at inspection hatch level. These are permanent modifications done to improve job site safety and provide more convenient access to tank inspection ports. This enhancement is highly desirable during frac operations where tank fluid levels are sensitive to job performance.
Standard Tanks With Front Catwalk Modification
LOW PROFILE 220 BBL OPEN TOP TANKS
The DHI 220 BBL open tops come equipped with or without gas diffusion apparatus. Optional weirs an be installed for solids management. These tanks are equipped with axles for easy low cost mobilization.
THE SAND TIGER™
The DHI Sand Tiger removes sand from flow-back effluent and is equipped with parallel cyclonic diffusion units. These diffusion operate at a positive pressure and permit the removal of first flash gas to be piped to a disposal solution such as DHI’s large bore flare system making this a 95% vapor emissions reduction on flow-back operations.
The Sand Tiger employs a high tensile 385,000 lb drag chain geared to remove sand at 30 cu.ft per minute.
