Abstract

Systems, methods, and apparatuses for pressure recovery and power generation may include a pressure recovery generator configured to receive a high-pressure fluid and generate current based on expansion of the high-pressure fluid. The current may be directed to a power electronics module that is configured to receive current from the pressure recovery generator and provide current to a closed-loop thermal cycle, such as an ORC. The current can be used to start components of the closed-loop thermal cycle, such as the pump and/or to black start the turbine generator. In some instances, the current can be combined with current generated by the closed-loop thermal cycle and directed to a utility grid or to external loads. The high-pressure fluid may be directed to heat exchanger components of the closed-loop cycle. For example, high-pressure, high-temperature fluid can be directed to an evaporator, while high-pressure, low-temperature fluid can be directed to a condenser.
