| A separation system is presented that partitions a slurry containing a plurality of particles that are influenced by a fluidization flow (which comprises teeter water and gas bubbles) and a fluidized bed. The separation system comprises a separation tank, a slurry feed distributor, a fluidization flow manifold and a gas introduction system. All of these components are arranged to create the fluidized bed in the separation tank by introducing the slurry through the slurry feed distributor and allowing the slurry to interact with the fluidization flow that enters the separation tank from the fluidization flow manifold. The gas introduction system is configured to optimize the gas bubble size distribution in the fluidization flow. The gas introduction system comprises a gas introduction conduit and a bypass conduit. The gas introduction system can be adjusted by modulating the flow of teeter water through the gas introduction conduit. | ||||||

| 9 | Process for reducing soluble organic content in produced waters associated with the recovery of oil and gas | US14416772 | 2013-07-22 | US09914136B2 | 2018-03-13 | Timothy J. Webber; T. Daniel Sikes; C. Steven Sikes |
| A chemical treatment process and separation module are described for removal of soluble organic compounds and suspended or emulsified oils and/or solids from produced waters that accompany operations for oil and gas recovery. The process occurs in its entirety within an interval of several minutes. The solubility of organic compounds is first reduced, in an optional step, by pH reduction, followed by treatment with coagulants and flocculants, the latter in conjunction with microbubble flotation. The organic compounds that are rendered insoluble, along with other oily solids, are captured in the floe created by the coagulant and flocculant treatment, and simultaneously made buoyant by the concurrent addition of microbubbles. The water and floe is passed over an array of sloped strainers that separates and diverts the floe from the effluent water, which contains significantly reduced soluble organic content. The separated stream of oily solids can be dewatered for disposal as waste. | ||||||

| A system for concentrating particulate mixtures of hydrophobic and hydrophilic material in a fluid medium is presented. The system comprises a separation chamber comprising three or more processing compartments in series. Each processing compartment comprises a manifold for the introduction of teeter water that comprises a mixture of water and air bubbles, suspended solids that form a fluidized bed that is created by the upward movement of the teeter water through the suspended solids; and each processing compartment is independently operable. An overflow launder is located above the separation chamber and a dewatering compartment is located beneath the separation chamber. | ||||||
