Abstract: An improved horizontal vapor-liquid separator providing a separation chamber, a horizontal inlet conduit having internal vanes for imparting a helical motion to fluid flow therethrough, a series of at least three pipe separators coaxially aligned with the inlet conduit and spaced apart to form annular orifices for the collection of heavier droplets forced to the inner peripheries of the piping by the centrifugal force, a conical baffle located in the path of the flow discharged from the end of the last separator pipe for coalescing final traces of liquid by impingement, and a vapor exhaust conduit coaxially aligned with the inlet conduit. A second chamber located beneath the separation chamber collects the liquid by gravity flow and utilizes a liquid level control system to maintain a vapor barrier while discharging the collected liquid at the same rate of accumulation.

Abstract: An electric treater for separation of a water-in-oil emulsion, which utilizes both AC potential applied to electrodes as well as DC potentials. A plurality of trays are provided through which the emulsion passes in series. One or more of these trays is supplied with AC potential to a series of insulated electrodes. Another tray is provided with a DC potential obtained from one half of a secondary winding of a transformer, through a rectifier, and at least a third tray is provided with a second DC potential derived from the opposite end of the secondary winding through a separate rectifier. The oil to be treated first passes through the tray or trays which have the AC potential, and then passes successively through the two trays which have the pulsed DC potential.

Abstract: An improved type of centrifugal separator for separating liquids such as oil and/or water from a mixture of gas and liquid. It consists of an upright cylindrical shell divided by transverse dividers into three chambers. The mixture of gas and liquid is introduced through a tangential diverter into the lower chamber to produce a high velocity vortex of gas and liquid. A central axial vortex tube penetrates and is sealed through both transverse dividers. This vortex tube is comprised of two spaced longitudinally aligned portions which define a gap between them. The gap is positioned inside the central chamber. The upper end of the vortex tube extends into the top chamber and is sealed into a first mist extractor. The lower end of the vortex tube extends into the lower chamber.Due to the vortex action the liquid is thrown outwardly against the inner wall of the shell, the gas forming a high velocity vortex column along the central axis of the shell.

Abstract: An apparatus for flamelessly reconcentrating liquid desiccant including vertically disposed upper and lower enclosed reboiler chambers having an enclosed heating section interposed therebetween. Water-rich liquid desiccant is continuously recirculated between the upper and lower reboiler drums through riser conduits disposed within the heating section and return conduits exterior thereof. Simultaneously with the recirculation of the water-rich liquid desiccant an exhaust gas stream from a prime mover is passed through the heating section to convectionally heat the liquid desiccant within the riser conduits causing disengagement of water vapors therefrom. The upper drum includes an outlet for the disengaged water vapors and also an outlet for the resultant water-lean liquid desiccant.
