    摘要： Provided herein are a heat engine system and a method for generating energy, such as transforming thermal energy into mechanical energy and/or electrical energy. The heat engine system may have a single charging pump for efficiently implementing at least two independent tasks. The charging pump may be utilized to remove working fluid (e.g., CO2) from and/or to add working fluid into a working fluid circuit during inventory control of the working fluid. The charging pump may be utilized to transfer or otherwise deliver the working fluid as a cooling agent to bearings contained within a bearing housing of a system component during a startup process. The heat engine system may also have a mass control tank utilized with the charging pump and configured to receive, store, and distribute the working fluid.

    摘要： Provided herein is a heat engine system and a method for transforming energy, such as generating mechanical energy and/or electrical energy from thermal energy. The heat engine system may have one of several different configurations of a mass management system (MMS) fluidly coupled to a working fluid circuit. The MMS may be utilized to control the amount of working fluid added to, contained within, or removed from the working fluid circuit. The MMS may contain a mass control tank, an inventory transfer line, and system/tank transfer valves. The MMS may contain a transfer pump fluidly coupled to the inventory transfer line and configured to control the pressure in the inventory transfer line. The MMS may have two or more transfer lines, such as an inventory return line and valve, and an inventory supply line and valve.

    摘要： Aspects of the invention disclosed herein generally provide heat engine systems and methods for recovering energy, such as by generating electricity from thermal energy. Generally, the heat engine system has a working fluid circuit containing a working fluid (e.g., sc-CO
    2 ) for absorbing thermal energy from the heat source stream via a heat exchanger. In one aspect, the method includes controlling a power turbine by modulating a turbo pump throttle valve and a power turbine bypass valve to adjust the flowrate of the working fluid entering the power turbine while monitoring and controlling process operation parameters of the heat engine system to synchronize the frequency of the power generator to the frequency of the electrical grid during a synchronization process.
