An apparatus for separating contaminants from a fluid stream is disclosed. The apparatus comprises a vessel containing a gas blanket. The apparatus will have contained therein a water skimmer member adapted for allowing for retention of the fluid stream. The apparatus further includes a first gas flotation cell contained within the vessel and arranged in series with the water skimmer so as to receive the fluid stream. Also included is an oil bucket positioned within the vessel and adapted to receive a portion of the fluid stream from the water skimmer and the first gas flotation cell. In one embodiment, the first gas flotation cell comprises a first screen member having a porous structure, a plate baffle having a first passage therein, and an eductor device adapted for introducing a gas stream into the fluid stream. In the preferred embodiment, the eductor device comprises a tube operatively associated with the vessel, the tube being in communication with the fluid stream; a nozzle member positioned within the tube and adapted to receive the fluid stream; a port formed on the tube and adapted to receive the gas contained within the gas blanket and introduce the gas into the elongated tube; and, a rotor member positioned within the tube and adapted to produce a properly sized and dispersed gas bubble array. Also, the apparatus may contain a plurality of gas flotation cells arranged in series so that the outlet of one feeds the inlet of another.

A method of cleaning a pipeline that may include the steps of pumping a process fluid through a flameless heating unit, preheating the process fluid before it enters a dynamic heat generator, controlling the flameless heating unit to heat the process fluid to a temperature in a range sufficient to melt deposits disposed in the pipeline, and transferring the process fluid from the flameless heating unit into the pipeline. Other steps may include using the heated process fluid to operate a tool operatively disposed in the pipeline, whereby the heated process fluid and the tool work collectively to melt and clear the deposits. The flameless heating unit may include an internal combustion engine, a dynamic heat generator operatively connected to the internal combustion engine, and a pump configured to provide a discharged fluid to the dynamic heat generator.

Apparatus for the dispersed gas flotation and separation of insoluble, dispersed contaminants from a liquid comprised of a horizontal series of flotation cells, separated by baffles that permit the substantially horizontal flow of liquid from one cell to the next, each cell being equipped with one or more gas dispersing nozzles and screens which aid in the coalescence and flotation of the contaminant particles, and an inclined baffle above the horizontal series of cells to urge the floated impurities toward a weir positioned to remove the impurities from the surface of the liquid.
