Heat recovery systems for flue gas or exhaust air in Chemical plants
Corrosion and fouling problems limit the recovery of more heat. With polymer heat exchangers you can recover additional heat and overcome these issues.
Improve thermal efficiency
Prevent Corrosion & Fouling
Reduce CO2 emissions
Your thermal processes are losing up to 15% of their energy through the stack
What is keeping you from recovering this energy?
Finding a robust heat exchange solution
Finding a technically feasible solution to recover and re-use waste heat is a challenge.
Corrosive and fouling flue gases
Your flue gas or dryer exhaust air is potentially corrosive or fouling at low temperatures.
We design and deliver heat recovery systems for Chemical plants to reduce their carbon footprint
Save up to 10% energy on your thermal process
Recover heat - that is now lost - from flue gas or exhaust air.
Your thermal process has waste heat recovery potential

The way our heat recovery system works
Capture waste heat
When hot flue gas and exhaust air leave the stack, they still contain a significant amount of energy. Our heat recovery system captures this heat from fired heaters, ovens, kilns, calciners, steam boilers, thermal oil heaters or dryers.
Preheat drying air, combustion air or water
Cold combustion air, drying air, process water, make-up water or boiler feed water are heated with the captured waste heat. This directly reduces the consumption of fossil fuels.
Our heat recovery systems for Chemical plants
Polymer Air Preheater
Warm up combustion air or drying air by extracting heat from flue gas or exhaust air. The air preheater is corrosion resistant, easy to maintain and to clean.
Stainless steel or Polymer Economiser
Warm up boiler feed water, make-up water or process water with waste heat from flue gases or exhaust air. The economiser is corrosion resistant and easy to maintain and to clean.
CPVC producer Lubrizol
8% energy consumption reduction
Lubrizol is committed to environmentally responsible and sustainable solutions. To reduce their energy consumption on a drying process of CPVC, they wanted to recover heat from the exhaust air of the dryer.
Previously no heat was recovered from the hot drying air, because of the high hydrochloric acid content in it. When cooled down, through the water and acid dew point, hydrochloric acid is formed and corrosion occurs.
A HeatMatrix polymer APH was selected, because of its ability to handle corrosive exhaust air. Incoming cold air is heated from 10 to 56 °C, resulting in an energy saving of 170 kW. Corrosion free heat recovery is achieved.
Your path to lower CO2 emissions, energy consumption and costs
Our process engineers assess technical feasibility of additional heat recovery on your process. The potential reduction in CO2 emissions and energy costs is determined.

What causes potential corrosion problems of flue gas?
Why can the HeatMatrix heat recovery systems be cleaned easily?
HeatMatrix heat recovery systems are designed for low maintenance cost. The polymer heat exchangers have a low tendency of chemical bonding and therefore a lower degree of fouling. Furthermore an in-situ cleaning system can be installed which will facilitate cleaning during operation and limits the required downtime for maintenance purposes. Our non-polymer heat recovery solutions are designed in such a way that cleaning can be done off-line and no operational stop is required.
Can HeatMatrix deliver projects turnkey?
This depends on the size of a project and the geography. If you contact us, we can judge the situation.
