“…The optimization of heat recovery is critical to solve the problem of the efficient use of energy and, consequently, to promote the reduction of gaseous emissions and consumption of oil and natural gas, since the reduction of energy consumption is closely linked to improvement of heat transfer (Cheng and Liang, 2012a;Kaluri and Basak, 2011;Onishi et al, 2013a;Wang et al, 2011). Thereby, harnessing energy from process streams through thermal integration between heat exchangers and cooling and/or heating systems is one of the most effective ways to reduce costs.…”
