Nalco provides innovative, eco-friendly services for water treatment and emission reductions in the power industry. The company has a worldwide client base, providing cost-effective solutions that are safe, reliable and help bring measurable returns on investments.

Water treatment solutions and dust control

Our solutions ensure that reliability is enhanced through the maximising of plant availability, preventing unscheduled downtime, reducing maintenance and increasing the lifespan of equipment.

Profitability is increased through the optimisation of heat rate and a reduction in water requirements and necessary manpower.

Operations efficiency is improved through increasing the effectiveness of condensers and cooling towers. Corrosion, scaling and fouling are prevented. There is also the optimisation of turbines and fuel use.

In addition, our services ensure the meeting of stringent standards for health and safety, as well as the environment. Control of dust and ash handling are improved, reliability and safety goals are achieved. In addition to reductions in water use, output of wastewater and greenhouse gas emissions.

Air protection solutions

The Nalco Air Protection Technologies (APT) group offers a complete range of solutions for control of mercury emissions at coal-fired power generation facilities.

Nalco APT optimises the air quality control devices (ACQDs) that reduce greenhouse gas emissions, with only minimal modification of existing equipment required by Nalco mercury solutions for their integration.

Mercury control technologies

A mercury reduction of more than 95% is provided by Nalco’s Nalco APT MerControlĀ®, which ensures that mercury emission requirements are met. In addition, stringent emission regulations are satisfied such as the Mercury and Air Toxics Standards (MATS / Utility MACT).

Cost-effective mercury emission treatment

Nalco’s mercury control solutions are easily integrated with existing air quality control devices (ACQDs), saving significant costs on buying new equipment, installation, and annual operations and maintenance. This simple integration with existing devices ensures that any impact on plant operations is minimal.

Preserving coal-combustion by-products

No harmful impacts on the resale value of by-products from coal combustion occur from using Nalco mercury control technologies.

Products include:

  • MerControl 7895, which significantly decreases the impact of activated carbon on fly-ash resale value for concrete applications
  • MerControl 8034 is a proven solution for complete removal of mercury re-emission without affecting the quality of gypsum
  • MerControl 6012 mercury sorbent is non-halogen and non-carbon. It captures mercury in spray dry absorbers (SDA) and circulating dry scrubbers (CDS)

Equipment, measurement and testing for mercury removal

Nalco provides onsite demonstrations of equipment, measurement, and other services so customers can gain a greater understanding of how Nalco’s mercury removal solutions can specifically benefit them.
