Variable Speed Reconfigurable Pump/turbine Clusters
18 Jan 24
A “hydraulic rotating machinery” (“HRM”) system provides optimal energy efficiency over a very wide conditions of service (“COS”) range by configuring a plurality of variable speed HRMs in a “cluster.” The HRMs are interconnected by one or more valves that can be actuated by a controller to configure and vary a flow path through which a process fluid flows from an inlet to an outlet.

30 Mar 23
A valve configured to control a flow of a process fluid includes a pair of packing seals separated by a seal gap space along a linear valve stem of the valve, and a pressurization port that can be used to apply a pressurizing fluid, such as nitrogen gas, to the seal gap at a gap pressure that is higher than the process fluid pressure, thereby ensuring that any leakage past the packing seals will be of pressurizing fluid into the process fluid and/or into the environment, and that no process fluid will escape into the environment.
