The present disclosure relates to a multi-pressure stage, organic Rankine cycle ('ORC') that includes a dry organic working fluid that may be split, such that a first portion of the working fluid flows through a high pressure stage and a second portion of the working fluid flows through a low pressure stage. Components of the high pressure stage and the low pressure stage may be heated by a heat source stream that may be split in a tee downstream of a high pressure evaporator and recombined in a mixer before entering a low pressure preheater.

Multi-pressure organic Rankine cycle

A system and method for generating electric power using a generator coupled to a turboexpander is disclosed. The system includes one or more thermal pumps configured for heating a fluid to generate a pressurized gas. A portion of the pressurized gas is discharged to a buffer chamber for further utilization in a Rankine system. A further portion of the pressurized gas is expanded in a turboexpander for driving a generator for generating electric power. Optionally, the system includes a pump to pressurize a portion of the fluid depending on the systems operating condition. The system further includes one or more sensors for sensing temperature and pressure and outputs one or more signals representative of the sensed state. The system includes a control unit for receiving the signals and outputs one or more control signals for controlling the flow of gases and liquid in the valves and the check valve.

System and method for generating electric power

An exemplary turbocharger system for an internal combustion engine is provided. The turbocharger system includes a first turbine and a second turbine. The first turbine is in fluid communication with the internal combustion engine. The first turbine receives a first portion exhaust gas discharged from the internal combustion engine and provides a first turbine exhaust gas. The second turbine is in fluid communication with the first turbine via an inter-stage channel. The inter-stage channel transports the first turbine exhaust gas from the first turbine to the second turbine. The inter-stage channel is in thermal connection with an exhaust gas recirculation channel defined between an inlet and an outlet of the internal combustion engine. The first turbine exhaust gas flowing through the inter-stage channel is capable of being heated by a second portion exhaust gas discharged from the internal combustion engine and flowing through the exhaust gas recirculation channel.
