Heat Integration in Chance of Hot Feed
An Exergo-economics mathematical model for heat integration across plants is presented.The model is considered total cost of integrated heat exchanger network (HEN) and long distance matches.The paper studies area heat integration in respect of HEN synthesis.Properly rising up the feed temperature (FT) of intermediate stream, the energy using process of the stream ”usually cooling in upstream plant, then heating in downstream plant” is avoided reasonably.But the total annual costs are increasing as the FTs rising if heat integration across plant is forbidden.To achieve total site energy optimization, heat integration across plants is permitted.Approaching optimum FT method is introduced to solve the model.The application of the model is illustrated with an example.The results show that equipment costs and operation costs are reduced sharply.
