System and method for managing thermal issues in one or more industrial processes
First Claim
1. A system for temperature conditioning inlet gas, comprising:
- a gas turbine having an inlet side and an outlet side;
at least one gas inlet heat exchanger operatively coupled to the inlet side of the gas turbine, wherein the at least one gas inlet heat exchanger is configured to remove heat from inlet gas being supplied to the inlet side of the gas turbine prior to entry of the inlet gas into the gas turbine and transfer such heat via a working fluid to a bottom loop;
at least one gas outlet heat exchanger operatively coupled to the outlet side of the gas turbine and fluidly coupled with the bottom loop, wherein the at least one gas outlet heat exchanger is configured to remove heat from outlet gas being generated by the gas turbine and transfer such heat via the working fluid to the bottom loop,wherein the bottom loop is configured to utilize such transferred heat from the at least one gas inlet heat exchanger and the at least one gas outlet heat exchanger to provide suitably conditioned working fluid back to both the at least one gas inlet heat exchanger and the at least one gas outlet heat exchanger, and comprises;
at least one bottom loop expander fluidly coupled to the at least one gas inlet heat exchanger and directly fluidly coupled to the at least one gas outlet heat exchanger, wherein the at least one bottom loop expander is configured to receive a heat-laden working fluid from the at least one gas outlet heat exchanger and yield a cooled working fluid; and
at least one bottom loop heat exchanger fluidly coupled with the at least one bottom loop expander, the at least one outlet heat exchanger, and the at least one gas inlet heat exchanger, wherein the at least one bottom loop heat exchanger is disposed downstream from the at least one bottom loop expander and upstream of the at least one gas inlet heat exchanger and the at least one gas outlet heat exchanger, the at least one bottom loop heat exchanger being configured to receive the cooled working fluid from the at least one bottom loop expander and transfer the cooled working fluid to the at least one gas inlet heat exchanger.

Abstract
The present invention generally relates to a system that enables one to both: (i) address various thermal management issues (e.g., inlet air cooling) in gas turbines, gas turbine engines, industrial process equipment and/or internal combustion engines; and (ii) yield a supercritical fluid-based heat engine. In one embodiment, the present invention utilizes at least one working fluid selected from ammonia, carbon dioxide, nitrogen, or other suitable working fluid medium. In another embodiment, the present invention utilizes carbon dioxide or ammonia as a working fluid to achieve a system that enables one to address inlet cooling issues in a gas turbine, internal combustion engine or other industrial application while also yielding a supercritical fluid based heat engine as a second cycle using the waste heat from the gas turbine and/or internal combustion engine to create a combined power cycle.
