Energy saving opportunities in heat integrated beverage plant retrofit

Abstract

This paper presents practical applications of mathematical programming for energy integration in a large beverage plant. The opportunities of heat integration between batch operations were analysed by a Mixed Integer Linear Programming (MILP) model, which was slightly modified by considering specific industrial circumstances. The feasibility of combined electricity, heating and cooling production was studied using a simplified MILP model, developed for the selection of an optimal polygeneration system. The superstructure includes cogeneration systems with different prime movers (steam turbine and gas turbine), and a trigeneration system with a back-pressure steam turbine. The proposed heat integration scheme and the selected cogeneration system may improve a company's economic performance and reduce its environmental impact.

Heat integration of intermittently available continuous streams in multipurpose batch plants

“…It was reported that the maximum amount of heat recovery can be increased considerably if the temperature of the recirculating hot fluid is varied with the operating condition. Tokos et al (2010) applied mathematical optimization models to a large beverage plant. Possibilities of heat integration (between batch operations) and polygeneration were analyzed, considering industrial circumstances.…”

The synthesis of cost optimal heat exchanger networks with unconstrained topology

“…The most recent publications about applications of process integration (see, e.g., [1][2][3][4][5]) and various aspects of HEN synthesis (see, e.g., [6][7][8][9][10]) confirm the interest of the research community in this field, the ultimate aim of which is cleaner production.…”
