Many, if not most, industrial processes are designed to preheat the feed streams with heat recovery from the product and byproduct streams. Sometimes waste heat is used to generate steam for facility heating and electric power generation. Heat recovery equipment is often inefficient, and most of the low temperature waste heat (less than 250 ℃) is not used. It is estimated that 20 to 50% of the energy consumed in industrial processes is discharged as waste heat. This heat can be discharged with the flue gas, with the cooling water, and ultimately to the environment as an increase in ambient air temperature.
Technology development can improve utilization of waste heat. Improvements in heat recovery equipment can reduce energy consumption, and new applications for using low-grade waste should be developed.
This symposium explores the opportunities to expand waste heat recover, especially at lower temperatures, and how to overcome the challenges associated with it.
Topics include but are not limited to the following:
Low Temperature Waste Heat Recovery: Challenges and Opportunities
Waste heat recovery has been used to reduce costs for energy intensive processes for decades. New initiatives and innovative uses have been proposed.
