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

A heat transfer system includes a power sub-system configured to receive a heat source stream, and one or more heat exchangers configured to transfer heat from the heat source stream to a working stream. The working stream is ultimately heated to a point where it can be passed through one or more turbines, to generate power, while the heat source stream is cooled to a low temperature tail. A distillation condensation sub-system cools the spent stream to generate an intermediate stream and a working stream. The working stream can be variably heated by the intermediate stream so that it is at a sufficient temperature to make efficient use of the low temperature tail. The working stream is then heated by the low temperature tail, and subsequently passed on for use in the power sub-system.
