Minimising emissions for plants worldwide

From Chile to China, from cement to coal-fired power plants, Airnord solutions are hard at work minimising emissions and securing plant performance.

Here are just a few cases from our thousands of successful projects. Contact us if you’d like to see more.

Case story

An emission level well below the guarantee

A leading European producer of limestone-based products, Nordkalk, asked us to install an APC solution at its plant in Köping, Sweden. The result surpassed all expectations: dioxin emissions were slashed by 50%, while dust emissions were reduced to only 3-5 mg/Nm³, well below the guaranteed level.

Case story

Major ESP upgrade in a 20-day window

South Korean steel giant POSCO posed us two challenges. One, could we upgrade the internals in the ESPs responsible for treating over two million m³/hr of sinter waste gas? Two, could we com-plete the task in a once-in-a-decade 20-day shutdown? We succeeded on both counts – and brought emissions down from 18 to less than 10 mg/Nm³.

Case story - Turn key solution

Turnkey cement ESP achieves < 5 mg/Nm³

Dutch cement maker ENCI entrusted us to deliver a complete turnkey APC solution for one of their cement plants. The solution comprised numerous elements: a large four-field ESP for de-dusting the kiln and dryer, PIACS® Control System, all connecting ductwork, supports, dust transport equipment, etc. The result was impressive, being operationally well below the guaranteed 5 mg/Nm³.

EXCEED EXPECTATIONS. AND THEN SOME

When signing a contract to install ESPs at a major paper mill in China’s Shandong province, we guaranteed particle emissions of less than 10 mg/Nm³. The actual result was – like numerous other Airnord projects – well below 5 mg/Nm³. What’s more, we were able to erect three new ESP chambers while the boiler was still in operation.

REMOVING DUST IN NON-FERROUS PROCESSES

Removing dust in non-ferrous, high-temperature processes such as copper, zinc, lead and nickel is challenging. Acidic gases and sticky dust create metallurgical dust build-ups that can negatively impact ESP availability and collection performance, and increase maintenance costs. Airnord ESPs overcome these tough conditions by delivering very high equipment availability, securing the maximum plant uptime expected in today’s business environment.

Case story - PIACS

OPTIMISING ESP PERFORMANCE FOR BAHRAIN STEEL

Although installed more than 20 years ago, our ESPs at a Bahrain Steel plant continues to limit emissions to well below 3 mg/Nm³. Keen to extend this impressive performance, and also secure high productivity, Bahrain Steel decided to install PIACS® units. The benefits were so decisive, it was decided to extend the use of PIACS® to even more ESPs.

Case story - Coromax

CLEARING THE AIR IN CHINA

Baosteel reached an agreement with local authorities to radically reduce dust emissions from two 350 MW coal-fired boilers in Shanghai. The project involved upgrading ESPs with two additional fields and 16 Coromax® Pulse units. Following installation, emissions had been lowered to compliant levels for a gas volume of 1,350,000 Nm³/h.

WHAT MAKES COROMAX® SO EFFECTIVE?

More than 500 Coromax® Pulse Systems have been installed worldwide. Download the brochure and see what makes it such a popular choice for plants keen to meet tough emissions standards – and slash power consumption – but without increasing collection areas.

Case story - GSA desulphurisation

REDUCING SO₂ BY MORE THAN 97%

It seemed like missions impossible: install a high-performance GSA desulphurisation solution at a cement plant in a tight installation window – and achieve results similar to those of more expensive wet scrubbers. Contact us to learn more about how the project for Norcem in Norway reduced SO₂ by 97.3%.

Case story - GSA desulphurisation

DIOXIN REMOVAL OF >99.9%

China’s special economic area of Shenzhen produces a lot of waste. And we were selected to help turn it safely into energy for the region’s burgeoning population. Following installation of GSA desulphurisation solutions and other APC equipment, we lowered dioxin emissions to 0.1 mg/Nm³ – a removal efficiency of >99.9%.

Case story - CompactClean

FULL ESP BENEFITS. AT A FRACTION OF THE SIZE AND COST

Some applications (brick ovens, lime kilns, district heating, etc.) do not require full-size ESPs. But they still need to meet tough emissions limits. In these cases, CompactClean™ is the ideal solution. Modular and pre-assembled, it can be installed in a fraction of the installation time, cost and size of full-scale ESPs.
