The system and process of the present invention will consist of specific monitors in tandem with interface probes reading in multiple locations, divert valves which are operated by the readings of the interface probes and online ppm monitors. Such monitors would function in conjunction with these leading indicators through a software program and computerized logic controller used to manipulate the controls of this system.

The present invention relates to separation of fluids. Apparatus has a cylindrical vessel with a stronger unit with better structural integrity. Changed the vital operations of the unit, specifically the recirculation rate of the system, lowering the overall discharge flow and increasing the discharge pressure, part and parcel with this change is the addition of multiple Eductors in each cell providing greater gasification per cell. The combination of these changes provides a greater overall efficiency thus the overboard water quality is improved using a smaller vessel to accomplish the objective. As important, is the placement of the Eductor in the vessel creating a rolling effect to move separated oil to a spillover point for collection. Thus the collection point is improved by eliminating costly mechanical wipers and using multiple adjustable spillover weirs in each cell to recover the collected oil contaminant during the process and will help preclude upset and or surge conditions from affecting the water quality at the effluent. The above features are a marked advancement, when taken in combination, to current induced gas flotation technology.

A method and apparatus for separating two fluids, one lighter in specific gravity than the other, including the steps of providing a single vessel, having a primary separation chamber and a gas flotation chamber; separating fluids in the primary separation chamber to allow for free and suspended solids along with free oil and grease and gas to be removed from the fluids in the primary separation chamber; flowing the fluids into the gas flotation chamber portion; providing a first induced gas flow; combining a second gas flow of micro-bubbles with the first gas flow; and introducing the combined gas flow into the gas flotation chamber portion to provide a source of micro-sized dispersed bubbles in the fluid to accelerate the lift necessary for separation of fine oil droplets, emulsified oil droplets, from the water flowing in the flotation chamber portion. The apparatus for introducing the micro-bubbles to be comingled with the first induced gas flow includes a static mixer, a DGF pump, eductor and a series of globe valves which can be part of the gas flotation system or retrofitted to an existing gas flotation system.

A process wherein a combination of two separation principles are combined into one space saving machine with portability to separate two distinct and different fluids one lighter in specific gravity than the other, including the steps of primary separation of fluids allowing for free and suspended solids along with free oil and grease to be removed in the primary separation chamber; utilizing parallel corrugated plates in the separation defining the distance of rise for a given oil droplet based on Stokes Law to remove the remaining large droplets of free oil and solids; and providing an induced gas flotation process which provides a finely dispersed bubble in the liquid to accelerate the lift necessary for separation of fine oil droplets, emulsified oil droplet, and suspended solids to meet a government discharge regulation. This combined technique can be configured in a single vessel without pumps or other methods of liquid movement.

In reviewing the oil industry for the past 30 years there has been a need for a low maintenance, low cost, space saving Induced Gas Flotation Cell. With this said, a method has been invented to do this by making several changes in the present design philosophy of induced Gas flotation. First by providing a cylindrical vessel we have made a stronger unit with better structural integrity, and minimizing the opportunity for accelerated corrosion, secondly by changing the vital operations of the unit, specifically the recirculation rate of the system, lowering the overall discharge flow and increasing the discharge pressure we have been able to increase retention time and increase bubble dispersion, part and parcel with this change is the addition of multiple Eductors in each cell providing greater gasification per cell. The combination of these changes provides a greater overall efficiency thus the overboard water quality is improved using a smaller vessel to accomplish the objective. As important, is the placement of the Eductor in the vessel creating a rolling effect to move separated oil to a spillover point for collection. Thus the collection point is improved by eliminating costly mechanical wipers and using multiple adjustable spillover weirs in each cell to recover the collected oil contaminant. during the process and will help preclude upset and or surge conditions from affecting the water quality at the effluent. The overall design and combined affect of these important features makes this an improvement over all conventional technology used today. The above features are a marked advancement, when taken in combination, to current induced gas flotation technology.
