Abstract: A shelf in a cooled compartment (10) has gaskets (32,42) selectively attachable and removable at sides (22,24,26) of the shelf. The gaskets (32,42) are configured to obstruct the flow of air at at least a portion of a gap between the shelf and a wall (14,16,18) of the compartment (10) on the side of the shelf where the gasket is attached.

Abstract: The disclosed downhole gas and solids separator employs centrifugal force for the downhole separation of gases and solids from a hydrocarbon production stream. The separator device generally includes an outer tube and an inner tube disposed within the outer tube. The disclosed separator further includes a flighting member disposed within the inner tube. The flighting member includes an inside diameter space that defines a cylindrical void space extending through the center portion of the flighting member. The disclosed separator also includes an outer annular space inside the outer tube. The outer annular space defines an annular void space between the exterior surface of the inner tube and the interior surface of the outer tube.

Abstract: The disclosed downhole gas and solids separator includes a suspended helical flighting member for efficient downhole separation of both gases and solids from a hydrocarbon production stream. Centrifugal force, provided by the flighting member, accelerates the coalescence of like materials to enhance separation of both gases and solids within the separator. Centrifugal force urges solids to the outer wall of the separator and gases toward the center, where passageways are designed to allow solids to efficiently migrate toward and accumulate at the bottom of the separator while simultaneously allowing gases to efficiently rise out of the separator device.
