Patent number: 9031705Abstract: 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.Type: GrantFiled: August 28, 2012Date of Patent: May 12, 2015Assignee: Recurrent Engineering, LLCInventors: Henry A Mlcak, Mark D Mirolli, Yakov Lerner

Patent number: 8375719Abstract: 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.Type: GrantFiled: May 10, 2006Date of Patent: February 19, 2013Assignee: Recurrent Engineering, LLCInventors: Lawrence Rhodes, Yakov Lerner

Patent number: 8117844Abstract: 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.Type: GrantFiled: July 17, 2007Date of Patent: February 21, 2012Assignee: Recurrent Engineering, LLCInventors: Mark D.

Patent number: 7516619Abstract: 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.Type: GrantFiled: July 14, 2005Date of Patent: April 14, 2009Assignee: Recurrent Engineering, LLCInventor: Richard I.
