S1  Análise de Sistemas Energéticos    Titulo: ENERGY CONSUMPTION IN A SUGAR PLANT USING PINCH TECHNOLOGY AND LINEAR PROGRAMMING   Resumo : USING PINCH TECHNOLOGY AND LINEAR PROGRAMMING, SEVERAL SIMULATIONS OF THE MULTIPLE EFFECT EVAPORATORS AND HEAT EXCHANGER NETWORK OF A TYPICAL SUGAR CANE PLANT AND ALCOHOL PRODUCTION WERE PERFORMED. THE OBJECTIVE WAS THE MAXIMUM HEAT RECOVERY AND THE REDUCTION OF STEAM CONSUMPTION. THE SIMULATIONS WERE DIVIDED INTO TWO GROUPS. IN THE FIRST, PINCH POINT METHOD WAS APPLIED TO ANALYZE THE BASIC PLANT AND THE INFLUENCE OF SEVERAL ALTERNATIVES (ELIMINATION OF VAPOR BLEED BETWEEN EVAPORATOR EFFECTS, NUMBER OF EVAPORATOR EFFECTS, MECHANICAL COMPRESSION OF VAPOR IN THE LAST EFFECT OF EVAPORATION). IN THE SECOND GROUP, USE WAS MADE OF LINEAR PROGRAMMING TO DETERMINE THE OPTIMIZED CONFIGURATION OF VAPOR BLEEDS FOR JUICE PREHEATING. SEVERAL ALTERNATIVES OF DEEP IMPACT IN STEAM CONSUMPTION ARE INVESTIGATED. KEYWORDS: ENERGY CONSERVATION, PINCH TECHNOLOGY, LINEAR PROGRAMMING, SUGAR AND ALCOHOL PRODUCTION.     Autores : Bannwart, Antonio C. Higa, Márcio 0 Leal, Manoel Régis de L.
