摘要： Heat engine systems having selectively configurable working fluid circuits are provided. One heat engine system includes a pump that circulates a working fluid through a working fluid circuit and an expander that receives the working fluid from a high pressure side of the working fluid circuit and converts a pressure drop in the working fluid to mechanical energy. A plurality of waste heat exchangers are each selectively positioned in or isolated from the high pressure side. A plurality of recuperators are each selectively positioned in or isolated from the high pressure side and the low pressure side. A plurality of valves are actuated to enable selective control over which of the plurality of waste heat exchangers is positioned in the high pressure side, which of the plurality of recuperators is positioned in the high pressure side, and which of the plurality of recuperators is positioned in the low pressure side.

摘要： Aspects of the invention generally provide a heat engine system and a method for activating a turbopump within the heat engine system during a start-up process. The heat engine system utilizes a working fluid circulated within a working fluid circuit for capturing thermal energy. In one exemplary aspect, a start-up process for a turbopump in the heat engine system is provided such that the turbopump achieves self-sustained operation in a supercritical Rankine cycle. Bypass and check valves of a start pump and the turbopump, a drive turbine throttle valve, and other valves, lines, or pumps within the working fluid circuit are controlled during the turbopump start-up process. A process control system may utilize advanced control techniques of the control sequence to provide a successful start-up process of the turbopump without over pressurizing the working fluid circuit or damaging the turbopump via low bearing pressure.

摘要： Provided herein are heat engine systems and methods for cooling a power turbine while maintaining the dry gas seals (DGSs) free of contamination during shutdown procedures. One method includes activating a shutdown procedure by closing multiple valves coupled to the turbine to stop the working fluid passing therethrough and opening one or more turbine vent valves to provide seal gas to vent. The seal gas may flow from a seal gas conditioning system, through a DGS cavity, across a labyrinth seal, through a labyrinth seal cavity, the turbine, and the turbine vent line, and into a leak recapture storage vessel and/or the ambient atmosphere. One method further includes maintaining a storage tank pressure less than a reference pressure of the labyrinth seal cavity and maintaining a conditioning system pressure and a DGS cavity pressure greater than the reference pressure.
