Horizontal Oil skimmer

Flow-Back Oil-Skim Tank

The DHI portable oil, water skimmer separation tank provides a simple and versatile piece of equipment that allows customers to efficiently and cost effectively separate good oil from produced and flow-back 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 will also serve as a solids trap for any sand or silt that enters the system. Frequent solids evacuation will be required to ensure efficient operation.

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

Gun Barrel Skimmer

Remove water from oil for re-use and recycle

Upright Gun Barrel Reaction Tank

The Oil skimmers work on the principal that oil floats on production water.  Oil is forced to the top of the tank and is discharged from a port that removes oil 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

•Flow-back oil recovery

•Chemical treatment reaction tank

BENEFITS

•Cleaner water discharge reduces water disposal cost

•Recovers sell-able oil at the well site

•Permits production to come on line earlier

•Rotational flow inside the tank maximizes retention time

Vapor tight tanks

Oil receiving and storage with controlled emissions

Vapor Tight Tank Solutions

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

The tanks are to be normally vented via dual 6” line to a larger diameter flare header (10” recommended) flowing to a combustion flare/burner or for atmospheric dispersion, in some case vapor recovery equipment may be employed to further reduce emissions.
