Abstract: An apparatus for gas and solids separation from down-hole fluids having an inner tube and an outer tube disposed about the inner tube. The annular region between the tubes contain a plurality of chambers, separated by fluid barriers. The chambers include an intake chamber to receive fluids from outside of the outer tube through an orifice, and processing chambers. Fluid communication between the intake and processing chambers is restricted to fluid flow through sets of tubes. Fluid communication between a lowermost processing chamber below the intake chamber and a lower processing chamber above the intake chamber is restricted to fluid flow through the inner tube. A block restricts fluid communication within the inner tube to other chambers above the intake chamber. Orifices in the inner tube of the processing chambers on either side of the block provide fluid communication across the block.

The apparatus includes an inlet for liquid to enter, and a plurality of heated sloped surfaces to create thin sheets of flowing liquid on the surfaces from which the liquid can vaporize to form vapor. The liquid flows from one surface to another, vaporizing the liquid.

Abstract: A shell-and-tube heat exchanger, for removing volatile substances from a polymer solution by degasification, includes a bundle of tubes arranged vertically and parallel to each other in a shell chamber through which a fluid heat-transfer medium flows. The upper end of each tube is fixed in an upper tube sheet and the lower end of each tube is fixed in a lower tube sheet, and the polymer solution flows through the tubes in the direction of gravity. One feature is that a multilayer woven wire fabric is attached to the top of the upper tube sheet. The finest meshed layer of the fabric has a mesh width of 50 ?m to 1000 ?m. The invention also relates to a method for removing volatile substances from a polymer solution by degasification in a shell-and-tube heat exchanger and use of the shell-and-tube heat exchanger.

Abstract: A method for removing gaseous inclusions from a viscous liquid in which a viscous liquid stream having gaseous inclusions is introduced into a refining chamber, resulting in a flowing viscous liquid layer. The viscosity of a bottom portion of the viscous liquid layer is reduced in a first refining zone in the refining chamber so as to produce an upwardly mobile reduced viscosity portion of the viscous liquid layer. Heat is introduced into the viscous liquid layer from above the viscous liquid layer in a second refining zone in the refining chamber downstream of the first refining zone, reducing the gaseous inclusions in said viscous liquid layer. Thereafter, the viscous liquid layer having substantially reduced gaseous inclusions is discharged from the refining chamber.

Abstract: In some embodiments, a chamber may be configured to separate oil and gas. For example, the oil and gas may be separated as they exit a compressor, an oil storage tank, etc. In some embodiments, the gas may be a heavy gas and the oil may be compressor oil. One or more heated baffles may interact with the oil and gas to increase the velocity of the gas flow to inhibit the gas from absorbing into the oil. In some embodiments, when the compressor feeding the chamber is operating at a decreased compression rate, the chamber may continue to heat the oil to vaporize impurities out of the oil. The impurities may then be vented out of the chamber through the bleed valve to a gas inlet scrubber.

Abstract: An apparatus for stripping and strengthening and subsequent condensing and final strengthening of an easily vaporizable component of a preferably aqueous mixture permits the heat necessary for stripping and strengthening to be transferred through a common heat transmission body (3), where the heat is derived from condensing the vapor generated by stripping and strengthening, which vapor via compression using a heat pump (26) has obtained the increase in boiling point necessary for condensation. The apparatus is comprised of two sections, namely a stripping and strengthening section or first section (1) and a condensing and final strengthening section or second section (2), said sections being joined around a common heat transmission body (3) forming a dividing wall, each section being further defined by a horizontal partially cylindrical housing (13) and an end wall at each end.

Abstract: A method for removal of gaseous inclusions from a viscous liquid in which a layer of filter particles is positioned in the viscous liquid and the viscous liquid is passed through the layer of filter particles, whereby the gaseous inclusions combine or coalesce within the layer of filter particles, forming larger gaseous inclusions which rise to the top of the viscous liquid and escape therefrom.

Abstract: A process is disclosed for thermally degassing a condensate or feedwater by heating the condensate or feedwater in a feedwater vessel/degassing means, to which preheated condensate is fed and from which feedwater for heating surfaces heated in a heat recovery steam generator is removed. Structurally simple degassing, advantageous in thermal terms, is achieved by virtue of the fact that the condensate is preheated in a first condensate preheater, and that a partial stream of the preheated condensate, which is preheated further in a second condensate preheater, is used to heat the condensate or feedwater in the feedwater vessel/degassing means.

Abstract: The compound/curvilinear immiscible liquid separator has a separator section with an outer, elongated, cylindrical shell aligned vertically opening into an upper transition section and vapor dome at the top and a lower transition section and solid/heavy crude containment section at the bottom. A center column is disposed in the axial center of the separator section and a plurality of serially connected curved plates are disposed between the outer shell and center column to define an elongated curvilinear flow path having reverse flow pathways. An oil-water-gas mixture is introduced into the separator section under pressure past heating coils and through the curvilinear path, the lighter density oil entering and being removed from the top of the center column, and heavier sludge and brine collecting in the containment section. Gases bubble up through the center column and are removed from the vapor dome.

Contact with the walls of the tapered extraction moves the composite bubble towards the exhaust manifold.
