| Abstract | Since early 60’s, scientific and industrial community has been interested on synthesis of optimum heat exchanger networks capable of minimum energy consumption and requiring few heat transfer equipments, and has been motivated to develop specialized tools and techniques to approach this problem. This work analyses heat integration opportunities of an Olefins Plant, identifies and quantifies reduction of energy consumption, and propose changes of the existent heat exchanger network to achieve these goals. Besides the analysis of plant design conditions, multiple operational scenarios were considered to propose modifications able to handle real plant operation (flexibility). On the strength of plant complexity and large dimension, work methodology was splitted in two parts: initially, the whole plant was evaluated with traditional Pinch Analysis tools, considering heat and power integration in conjunct since refrigeration cycles are available. From this initial evaluation, opportunities are identified and modifications proposed. After that, modifications are segregated so as to represent small and independent portions of the original process. One of them is selected to be reanalyzed, considering two distinct operational scenarios. The reduction of problem dimension allowed mathematical methodologies to the synthesis of flexible networks to be applied, generating a feasible modification capable to fulfill proposed operational scenarios. |
