flotation separation gas

Product Definition Frames, a family of oil and gas

Induced Gas Flotation A Frames Induced Gas Flotation Unit (IGF) receives water from the Coalescing Plate Separator (CPI), as well as an additional stream from the second stage separators and dehydrators. Water from the CPI still contains dissolved gas, which will be used in the IGF vessel for gas flotation.

Induced gas flotation

Induced gas flotation (IGF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by injecting gas bubbles into the water or wastewater in a flotation tank or basin.

An overview of oilwater separation using gas flotation

Gas flotation systems are generally preferred over the setting methods due to the following significant advantages (i) shorter retention time and higher loading rate (ii) compact and smaller foot print (iii) better separation efficiency in removing smaller and lighter particles and (iv) higher effluent quality in the presence of chemicals (coagulants and flocculants).
