# HTRI Horizons Symposium

## Utilization of Low-Grade Waste Heat in Industry

## June 6 – 7, 2024 | Denver, Colorado, USA | Four Seasons Hotel Denver

[Register Now](https://www.htri.net/events/434/registrations/new)

Horizons Symposium registration closes on May 28. 2024 at 11:59 CDT  
Registration fee: US$650.00

[Program schedule](https://info.htri.net/horizons/2024/program-schedule) now available online.

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:

- Organic Rankine cycles
- Absorption chillers
- Mechanical vapor compression heat pumps
- Novel heat exchanger technologies
- Efficient combined heat and power cycles
- Thermal storage solutions
- Geothermal power
- Carbon capture processes using waste heat
