Waste heat recovery (WHR) is very important for both sustainability and profitability of process industries. It is even more important in Singapore because of very high industrial activity and lack of energy resources such as oil, natural gas and coal.
WHR has great potential for reducing fresh fuel demand by recovering waste heat and reusing it. It can simultaneously reduce both the heating and cooling loads and hence reduce operating and/or capital costs. It will also reduce CO2 emissions.
Consequently, heat recovery projects can generate credits within the CRM and carbon trade programs, and hence improve financial return on WHR projects. WHR is equally beneficial for both Greenfield (i.e., in new plants) and Brownfield (in existing plants) projects.
