Horizontal Oil Skimmer

FLOWBACK OIL SKIMMER

The DHI portable oil skimmer separation tank is a simple yet versatile piece of equipment that provides customers with a cost-effective way to efficiently separate good oil from both produced and flowback water at the well site.

The tank requires no setting or calibration to effectively separate oil from water. Flow rates up to 10 bbl/min of combined fluids separate very effectively. Emulsions may require additional chemical or thermal treatment to stimulate separation.

The equipment also serves as a solids trap for any sand or silt that enters the system. Frequent solids evacuation is required to ensure efficient operation.

The DHI oil skimmer comes in open-top and closed-top vapor tight configurations.

Gun Barrel Skimmer
Removes water from oil for reuse and recycle

UPRIGHT GUN BARREL SKIMMER

Oil skimmers work on the principle that oil floats on production water. Oil is forced to the top of the tank and is discharged from a port that removes it from a raised skimmer bucket.

Water is forced to a level before it can achieve access to the outlet, creating the oil trap.

APPLICATIONS

  • Temporary production gun barrel/wash tank

  • Water treatment/oil removal

  • Flowback oil recovery

  • Chemical treatment reaction tank

BENEFITS

  • Cleaner water discharge reduces water disposal cost

  • Recovers sellable oil at the well site

  • Permits production to come online earlier

  • Rotational flow inside the tank maximizes retention time


Vapor Tight Tanks
Oil receiving and storage with controlled emissions

VAPOR TIGHT TANK SOLUTIONS

Vapor tight tanks are designed to hold a pressure of 32 oz/sq.in, which is considered a positive pressure atmospheric tank. The pressure relief systems supplied by DHI are typically set at 16 oz/sq.in, venting to atmosphere.

Tanks are normally vented via dual 6-inch line to a larger diameter flare header (10-inch recommended) flowing to a combustion flare/burner. For atmospheric dispersion, vapor recovery equipment may be employed to further reduce emissions.
