Patent number: 8444859Abstract: 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.Type: GrantFiled: April 13, 2012Date of Patent: May 21, 2013Assignee: Cameron International CorporationInventors: James C.

Patent number: 8173017Abstract: 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.Type: GrantFiled: October 17, 2008Date of Patent: May 8, 2012Assignee: Cameron International CorporationInventors: James C.

Publication number: 20110042288Abstract: A coalescer is used in series with a hydrocyclone to enhance the removal of a dispersed phase from a continuous phase by first using a coalescer that lacks removal of any separated dispersed phase prior to cyclonic action in the hydrocyclone. The dispersed phase may be oil and the continuous phase may be water. The coalescer has no oil outlet and serves to coalesce the droplets or particles of the disperse phase together thereby increasing contaminant size distribution. The hydrocyclone functions as a separator operating at higher removal efficiency. The method and apparatus are useful to clarify produced water from hydrocarbon recovery operations, particularly those on offshore platforms where it is desirable to reduce weight and footprint area but still achieve very low oil concentration in the clarified water—even to levels sufficient for the water to be discharged directly into the environment, e.g. the ocean.Type: ApplicationFiled: August 31, 2010Publication date: February 24, 2011Applicant: Cameron International CorporationInventors: James C.T.

Publication number: 20110042304Abstract: Two hydrocyclones used in series enhances the removal of a dispersed liquid phase from a continuous liquid phase by cyclonic action. The first hydrocyclone has no overflow outlet and serves to coalesce the droplets or particles of the disperse phase together thereby increasing contaminant size distribution. The second hydrocyclone functions as a separator operating at higher removal efficiency. The method and apparatus are useful to clarify produced water from hydrocarbon recovery operations.Type: ApplicationFiled: August 31, 2010Publication date: February 24, 2011Applicant: Cameron International CorporationInventors: Shaya Movafaghian, James C.T.

Patent number: 7638062Abstract: 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.Type: GrantFiled: July 10, 2006Date of Patent: December 29, 2009Assignee: Cameron International CorporationInventors: Shaya Movafaghian, James C.
