Waste Heat To Energy

Calgon Carbon benefits from capturing waste heat from our operations. Waste heat is captured and used for a variety of purposes in order to reduce our energy demand for processes such as for steam generation, heating air and process water and building and space heating.

Through waste heat recovery, last year Calgon Carbon sites collectively generated more than 100,000 GJ of energy. Each opportunity to reduce energy demand also equates to a reduction in greenhouse gas emissions, and the continuation of waste heat recovery practices prevented the emissions of more than 16,000 metric tons of greenhouse gas emissions.

• Our Feluy facility in Belgium recovers waste heat from a reactivation furnace to generate steam, which in turn is used to produce electricity onsite.
• The Big Sandy facility in the U.S. also captures waste heat to generate steam used for temperature control, process water and air heating and building and space heating throughout the facility.
• The UV Technologies division reduces energy demand by the seasonal relocation of a 60 ton chiller. When located indoors, the heat released by the chiller offsets building heating requirements. When located outdoors, stress on the building's cooling system is reduced. This practice is dynamic and correlates to testing levels at the facility.

Scheduled for completion in the spring of 2017, a capital project at our Pearlington, MS plant will install a heat recovery steam generator (HRSG). Steam produced by the HRSG will reduce the steam demand from our natural gas boiler, reducing natural gas consumption of the facility. While energy savings is dependent on processing conditions, the site's natural gas consumption is estimated to be reduced by more than 9,000 GJ each year. Associated reductions in greenhouse gas emissions are estimated at more than 500 metric tons as a result of this capital project.
