Abstract: A filter housing has a first housing part with a first rim section and a second housing part with a second rim section. The housing parts can be joined and separated from each other in axial mounting direction and define a housing interior for a filter element provided with a circumferentially extending sealing element. The first and second rim sections form a receiving area in which the sealing element is seal-tightly clamped radially between the first and second rim sections when the housing parts are joined in the mounted state. A snap connecting device axially braces the first and second housing parts relative to each other. The snap connecting device is formed integrally on the first and second housing parts such that a clamping force applied by the first and second rim sections on the sealing element in radial direction is decoupled from the snap connecting device.

Abstract: Inlet and outlet connections of a well manifold connect to integrated piping of a unitary vessel on a skid. The unitary vessel defines an interior separated into two chambers by a barrier. One chamber has a test inlet for well testing operation, and the other chamber has a production inlet for production operation. Each of the chambers is in communication with a gas outlet for gas, a water outlet for water, and a condensate outlet for condensate. Each of the chambers has a weir plate disposed in the chamber and separating the water outlet on a waterside of the weir plate from the condensate outlet on a condensate-side of the weir plate adjacent the barrier. During use, the second chamber can be isolated so well testing operation can be performed using the first chamber. Also, the first chamber can be isolated so production operation can be performed using the second chamber.

Abstract: A promoted activated carbon sorbent is described that is highly effective for the removal of mercury from flue gas streams. The sorbent comprises a new modified carbon form containing reactive forms of halogen and halides. Optional components may be added to increase reactivity and mercury capacity. These may be added directly with the sorbent, or to the flue gas to enhance sorbent performance and/or mercury capture. Mercury removal efficiencies obtained exceed conventional methods. The sorbent can be regenerated and reused. Sorbent treatment and preparation methods are also described. New methods for in-flight preparation, introduction, and control of the active sorbent into the mercury contaminated gas stream are described.
