Greenhouse gas (GHG) emissions have become a growing concern for many industrialized countries over the past few years. Beyond the specific issues of GHG and general environmental considerations, there is a global tendency for improved energy efficiency. Whether the price of energy is high or low, controlled and reduced energy consumption will naturally improve operators’ margins. As a result, the use of energy is minimized by heat integration, heat recovery and reduction in heat loss to atmosphere. A waste heat recovery unit (WHRU) is a type of heat exchanger that recovers waste heat from hot flue gases and integrates heat into the balance of plant operations. The WHRU can generate steam/s
