Abstract: It has been discovered that a mechanical flotation system (10) having only two cells (18, 20) can be nearly as efficient as one having more cells, yet provide an apparatus with a considerably smaller footprint, significantly reduced capital and operating costs, as well as be resistant to floating oil recovery platform wave effects. The dual-cell mechanical flotation system (10) has, in sequential order, an inlet chamber (16) and two gasification chambers or cells (18, 20), each with at least one gas ingestion and mixing mechanism (32), and a discharge chamber (24). A common primary skim collection channel (40) atop the partition (44) dividing the gasification chambers (18, 20) efficiently channels away the bulk of the floating collected matter. At least one baffle (60) depending from the top of the vessel (12) near the primary skim collection channel (40) helps dampen the action of the fluid containing the suspended matter when the vessel (12) is affected by wave motion against the floating oil production platform. The liquid or froth levels (50, 66, and 76) can be intermittently raised for collection or otherwise lowered during periods of excessive turbulence (e.g. pitch or roll) to prevent clarified liquid from being collected with suspended matter.

Abstract: The seeding of calcium carbonate into a calcium chloride-contaminated monoethylene glycol (MEG) stream accelerates the growth of calcium carbonate particles to a size that enhances their removal from the stream by filtration. A seeding vessel allows the calcium carbonate particles a time period to grow. Sodium carbonate may be added to the contaminated stream to facilitate calcium carbonate particle growth. A recycle seeding conduit may recycle seeds from a filtration unit to the seeding vessel. A base such as sodium hydroxide may be added to accelerate the precipitation process.

Abstract: A cyclonic flotation system may be used to separate oil, grease, solids and other suspended matter from produced water by a combination of flotation and centrifugation in a separator cyclone. The cyclonic flotation system has a higher capacity-to-footprint ratio compared to conventional apparatus resulting in reduced weight and cost. The system is motion independent and suitable for use on floating structures such as offshore platforms and vessels.

Abstract: A mechanical vessel may effectively and simultaneously displace a first undesired gas from within water with a second desired gas, and remove at least one alkaline species and oily matter from the water. The vessel raises the pH of the water and reduces the lime requirement for subsequent lime softening. The vessel receives the water containing the first gas and passes the water through a series of gasification chambers. Each gasification chamber may have a mechanism that ingests and mixes a second gas into the water thereby physically displacing at least a portion of the first gas into a vapor space at the top of each gasification chamber from which it is subsequently removed. There is an absence of communication between the vapor spaces of adjacent chambers. An acid is added to remove the alkaline species, where the first gas is an optional by-product that is also removed.

Abstract: A mechanical flotation system having only one cell may be nearly as efficient as one having two or more cells, yet provide an apparatus with a considerably smaller footprint, significantly reduced capital and operating costs, as well as be resistant to floating oil recovery platform wave effects. The single-cell mechanical flotation system may have one skim collection channel that at least partially surrounds a single gas ingestion and mixing mechanism. At least one baffle may direct suspended matter or floc toward the skim collection which may be circular. The gas layer over the liquid is not vented for the purpose of gasification. The vessel may be a cylindrical pressure vessel oriented vertically, and optionally the inlet may be tangential to the periphery of the vessel to impart liquid rotation inside the vessel when liquid is introduced.

Abstract: The present invention provides a system and method for enhancing hydrocarbon production from a subsurface hydrocarbon-bearing formation. The system includes a mechanical fluid treatment unit that substantially reduces the concentration of precursor ions from the injection water. The treated water is injected under pressure into an injection well to cause the hydrocarbons to flow toward a production well. A chemical unit injects selected amounts of additives into the injection well to inhibit in-situ growth of crystals from insoluble salt precipitates formed due to the interaction of precursor ions present in the injected water and ions residents in the reservoir. The selected chemicals and their respective amounts are determined at least partially based on reservoir characteristics and the concentration of precursor ions in the treated water.

Abstract: The invention relates to a method of separating a multiple phase liquid medium comprising a first liquid phase and a second liquid phase wherein the medium is contacted with a first filter, said filter having been wetted by a wetting agent miscible with the first liquid phase but immiscible with the second liquid phase; whereby the first liquid phase passes through the filter, thus obtaining a filtrate substantially free of the second liquid phase. In a preferred embodiment, separation of a multiple phase liquid medium comprising liquid fossil fuel, water and biocatalyst employing one or two filters is disclosed. One filter will preferentially collect either the liquid fossil fuel or aqueous phase as the filtrate. The retentate will then flow to the second filter which will collect the component not removed before, i.e. the aqueous phase or liquid fossil fuel, as the filtrate. The remaining retentate, containing the biocatalyst, can then, preferably, be recycled. The process can be used to resolve an emulsion or microemulsion of the liquid fossil fuel and aqueous phase resulting from a BDS process. Also described is a method for controlling the reaction parameters of a mixed phase reaction process.
