Abstract: A Kalina Cycle control system monitors one or more operating parameters of the Kalina Cycle. The system calculates one or more optimal operating parameters that allow the Kalina Cycle to operate at an increased efficiency. The system automatically adjusts the one or more actual operating parameters to the optimal parameters to increase the efficiency of the Kalina Cycle. Methods of increasing the efficiency of a Kalina Cycle include automatically adjusting one or more operating parameters to an optimal configuration.

Abstract: The present invention is directed to a turbine seal system. The turbine seal system captures working fluid which is escaping from a closed loop thermodynamic cycle system, condenses the captured working fluid, and returns the condensate back to the thermodynamic cycle system. The turbine seal system is configured to apply nitrogen, or other non-condensable, or other material, to capture or mix with the escaping working fluid. The combined mixture of working fluid which escapes the turbine and the nitrogen utilized to capture the working fluid is evacuated by an exhaust compressor which maintains a desired vacuum in a gland seal compartment of the turbine seal. The combined mixture can then be sent to a condenser to condense the working fluid vapor and evacuate the non-condensables, forming a working stream. Once the non-condensables have been evacuated, the working stream is pumped to a higher pressure, and prepared to be re-introduced into the thermodynamic cycle system.

Abstract: The present invention relates to systems and methods for implementing a closed loop thermodynamic cycle utilizing a multi-component working fluid to acquire heat from two or more external heat source streams in an efficient manner utilizing countercurrent exchange. The liquid multi-component working stream is heated by a first external heat source stream at a first heat exchanger and is subsequently divided into a first substream and a second substream. The first substream is heated by the first working stream at a second external heat source stream at a second heat exchanger. The second substream is heated by the second working stream at a third heat exchanger. The first substream and the second substream are then recombined into a single working stream. The recombined working stream is heated by the second external heat source stream at a fourth heat exchanger.

Abstract: An improved apparatus and method for transporting gas through long pipelines is provided. The invention provides a binary mixture (e.g. ammonia-water) KALINA CYCLE® that is used as a bottoming cycle with a gas turbine. The non-isothermal boiling and condensation of the binary mixture achieves a high degree of recuperation. By throttling a part of the binary mixture, cooling is provided to the inlet air chiller for the gas turbine air compressor, which significantly improves the performance of the gas turbine. Thus, the invention provides a system for inlet air chilling integrated into a gas turbine-KALINA CYCLE® combined cycle used in a gas pipeline compressor station for pumping natural gas.
