The Pinch energy saving technology is an appropriate technology to design and optimize cogeneration processes. This research achieved the development of a cogeneration methodology for an enterprise from the dairy industry with an energy characterization; a viable energy source is coupled to heat exchanger equipment, which will be evaluated by technology Pinch and obtain efficient use of heat and subsequent use. According to the methodology designed, conventional system handles an energy efficiency of about 37% and cogeneration system proposed 80.1%; in primary energy consumption (natural gas) this is reduced by 30% with a reduced cost of 50%kWh.
