    Abstract: A system for controlled recovery of thermal energy and conversion to mechanical energy. The system collects thermal energy from a reciprocating engine, specifically from engine jacket fluid and/or engine exhaust and uses this thermal energy to generate a secondary power source by evaporating an organic propellant and using the gaseous propellant to drive an expander in production of mechanical energy. A monitoring module senses ambient and system conditions such as temperature, pressure, and flow of organic propellant at one or more locations; and a control module regulates system parameters based on monitored information to optimize secondary power output. A tertiary, or back-up power source may also be present. The system may be used to meet on-site power demands using primary, secondary, and tertiary power.

    Abstract: A system for carbon capture and energy optimization includes a gas treating system configured to remove CO2 and/or H2S from combustion device exhaust gas or natural gas during a sweetening process. One or more heat recovery heat exchangers recover thermal energy from the combustion device and/or the gas treating system. A thermal fluid loop transfers the recovered thermal energy to the gas treating system, one or more cooling subsystems, and/or auxiliary systems, enhancing gas recovery, energy efficiency, and system cooling. A control module dynamically manages energy recovery and allocation across the system to maximize CO2 capture and energy efficiency. The system may include waste heat chillers for cooling combustion exhaust gas and stripped CO2 gas, as well as predictive energy management features to optimize thermal energy distribution based on operational parameters. The system supports modular scalability and integration with multiple combustion devices to facilitate efficient and flexible carbon capture applications.

    Abstract: Technologies and techniques for converting thermal energy into mechanical and/or electric energy using an integrated thermal energy recovery system. This system employs an Organic Rankine Cycle (ORC) with a propellant heat exchanger, an expander, and a condenser, coupled with heat exchangers for transferring waste heat from an engine to ORC propellant. Sensors generate data reflecting environmental and operational conditions. A control circuit, incorporating a predictive module trained on a neural network, identifies non-linear relationships and sequences for optimizing ORC performance. The control circuit analyzes sensor data to determine if target operational values for waste heat recovery and power generation can be achieved within a specific timeframe. If not, the circuit dynamically adjusts the system via control signals to optimize net power by managing heat flow between thermal fluids, engine jacket water, engine exhaust, and/or ORC propellant to maintain target values.

    Abstract: A method and system is provided for pressure balancing one or more seals in machines such as expanders and/or compressors using the process fluid which is being expanded or compressed to provide the pressure for pressure balancing the other side of the one or more seals. The one or more seals may be part of a pressure containing chamber which may comprise a seal, a bearing and/or a gear on a rotating shaft common to the seal. An amount of pressure to be supplied to housing(s) for a machine so as to create a pressure cascade, and thereby dropping the pressure in each subsequent chamber as pressure approaches atmosphere. Pressure differentials may be directed to leak process fluid to the chamber into the process. Pressurized lube oil systems may be employed for balancing pressure and delivering lubricant to the seals, bearings and gears.
