Abstract: A compressor system for creating essentially liquid-free fluid flows includes a screw compressor that has an inlet port for receiving a low pressure gas stream, a main lubrication injection port for receiving an injection branch of a filtered lubrication stream, an inlet bearing lubrication port for receiving an inlet branch of the filtered lubrication stream, a discharge bearing and seal lubrication port for receiving a discharge branch of the filtered lubrication stream, a prime mover for powering the rotary screw compressor and a discharge port for discharging a high pressure compressed gas mixture stream from the compressor. The system further includes a separator for receiving the compressed gas mixture stream from the compressor. The separator has at least a primary and a secondary coalescer devices connected in series, such that the primary coalescer device has a smaller surface area than the secondary coalescer device.

Abstract: A connector device for connecting a wellhead christmas tree assembly to a wellhead wherein the device comprises a cylindrical body adapted to be placed in sleeved relationship to the wellhead and having means for attaching a wellhead christmas tree assembly in coaxial relation therewith. The cylindrical body member is further provided with a plurality of lateral openings in equiangular relationship with respect to the axis of the body member. The connector further includes a plurality of locking dogs, each having a toothed front face in conforming configuration with the wellhead exterior and each disposed in a different one of the lateral openings. The connector also includes a first drive means comprising a locking sleeve with an internal camming surface for interacting with a matching cam surface on the back face of each of the locking dogs and adapted by an actuator to drive the locking dogs into locking engagement with the wellhead.

Abstract: A method to process waste water by removing metals, such as nickel or iron during the production of alkali metal hydroxides comprising the steps of: mixing the waste water with a cell liquor and blending the two fluids, magnetically removing up to 33% of the metals present in the solution from blended fluids using a first magnet prior to evaporation, flashing and cooling of the blended fluids, and then magnetically removing an additional amount of metals from the resultant more concentrated caustic solution using with a second magnet prior to filtration of the more concentrated caustic solution.
