Induced Gas Flotation (IGF) Unit

• TI-IGF-50 – induced gas flotation deoiler for 50,000 barrels of produced water a day.
• Multi-cell horizontal unit – flotation cells in series for the standard duty.
• Parallel units – two or more units for larger flows or spare capacity.

• Capacity: typically 50,000 barrels a day per TI-IGF-50 unit, or to client specification
• Flotation gas: produced gas, fuel gas or nitrogen, to client specification
• Inlet oil content: sized to the duty, or to client specification
• Outlet quality: to suit the downstream filter or the injection specification
• Vessel: designed to ASME VIII or client specification
• Materials: carbon steel with internal coating, or stainless steel, to client specification
• Rotating equipment: proven pumps from leading makers, packaged on a skid designed and built by Tech Inc.
• Control: PLC with level and skim control, and signals to the plant DCS or SCADA

What capacity does one unit treat?
Typically 50,000 barrels of produced water a day per TI-IGF-50, with parallel units for larger flows or spare capacity.

Which gas is used for flotation?
Produced gas, fuel gas or nitrogen, to suit the site.

Where does it sit in the water train?
Between primary separation or hydrocyclones and final filtration, as the secondary deoiling stage.

Which materials are used?
Carbon steel with internal coating, or stainless steel, with vessels designed to ASME VIII.

The IGF unit removes most of the dispersed oil left after free-water knock-out, production separators and hydrocyclones, which cuts the load on the nutshell filters or cartridge polishing downstream. It runs on water-injection and waterflood projects and ahead of disposal wells, at onshore gathering centres and on offshore facilities alike.

• Effective oil removal – fine gas bubbles lift dispersed oil droplets to the surface for skimming.
• Compact footprint – a short residence time keeps the vessel small compared with gravity skim tanks.
• Handles load swings – cells in series smooth out changes in inlet oil content.
• Closed gas system – the gas blanket and vent keep hydrocarbon vapour contained.
• Skid-mounted delivery – vessel, pumps, piping and controls tested before shipment.
