摘要： A seating and locking system for turbomachinery attached to the customer column housing the turbomachine. The seating and locking system includes two or more actuated pistons that push against a piston seat or locking groove of the turbomachine. The actuated pistons secure the turbomachine within the costumer column to prevent the turbomachine from moving and getting damaged. The seating and locking system further includes a seat attached below the customer column with two or more spring loaded rods. The seat forces the customer column and the turbomachine to remain fixed to the bottom of the vessel housing the customer column and the turbomachine. Embodiments can be used with pumps, expanders, turbines, compressors, and fans.

摘要： An ammonia expander in a liquefaction process, the ammonia expander reducing the resulting vapor from the liquid ammonia expansion and increasing the percentage of both the feed gas input and the process output. Embodiments of the ammonia expander comprise a radial inflow reaction turbine with an induction generator mounted on a generator shaft and a turbine mounted on a turbine shaft, the turbine submerged in the liquid ammonia. The turbine extracts torque from the liquid ammonia as it flows through the turbine. The torque from the turbine is transferred from the turbine shaft to the generator shaft, allowing for energy to be extracted from the liquid ammonia stream.

摘要： Vane, fin, and hole arrangements establish a predetermined reduced swirl at the inlet of mechanical seals and the inlet of a variable axial orifice gap which act in harmony as an axial thrust equalizing system for use in liquid cryogenic turbines and pumps. In said establishment the stiffness, damping, and inertia in said seal in conjunction with said variable orifice gap is manipulated, including the destabilizing cross-coupled stiffness which is reduced. Said seal is of either labyrinth annular type formed by a plurality of teeth, annular smooth, or a plurality diamond annular surface pattern. Said variable orifice gap is smooth. Liquid for the axial thrust equalizing seal is initially bled from the main to pass through a preset deswirl mechanism. The deswirl mechanism consists of either a plurality of vanes, fins, grooves, or circular holes that guide liquid radial inward before passing through said mechanical seal. After exiting the seal said liquid passes through a second deswirl mechanism consisting of a plurality of vanes, fins, or grooves before entering a variable axial orifice gap. The variable orifice moves in axial position to variably restrict balancing liquid and generate backpressure in the pressure chamber to balance the axial thrust caused by a plurality of impellers on the same single shaft. After passing through the variable orifice the bleed liquid can pass past a sealed lubricated roller bearing for heat exchange to cool said bearing with the cryogenic liquid along grooves in a bearing liner. Alternatively the liquid can also pass directly through an open unsealed bearing for cooling.
