New microwebsite "SCR Catalyst testing" is now online

Why is SCR catalyst testing so important?

Reducing costs in deNOx plants through extending SCR catalyst lifetime and finding optimal asset management scenarios begins with a trustworthy and unbiased assessment of the condition of the catalysts. But SCR catalyst testing can be tricky, since selecting the right tests calls for the right questions to be asked first. At ENGIE Laborelec, you’ve come to the right place. We perform the complete range of regular and more specialized SCR catalyst tests. You get unbiased support to fit your objectives, independently from the original equipment manufacturer or regeneration company.

Catalytic deNOX systems are costly, and catalysts have to be replaced regularly. But what you may not already be aware of is that the CAPEX and OPEX of deNOX systems can still be significantly reduced, typically up to 100,000 € a year. Want to know how? Get your copy of our brochure here or contact us for an in-depth consultation. Our experts will explore with you any opportunities for improvement, evaluating how realistic these are, while bringing all the necessary elements to calculate the gains to be made.

Effect of a gas–gas-heater on H2SO4 aerosol formation: Implications for mist formation in amine based carbon capture

Authors: Jan Mertens, R. Bruns, B. Schallert, N. Faniel, P. Khakharia, W. Albrecht, E. Goetheer, J. Blondeau, K. Schaber

This study presents the potential of a gas–gas-heater (GGH) to minimise amine emissions.

  • A GGH removes up to 70% of sulphuric acid from the flue gas.
  • A GGH prevents the homogenous nucleation of sulphuric acid into aerosols.
  • Information will serve designing future aerosol emission countermeasures.

Collection and Generation of Sulfuric Acid Aerosols in a Wet Electrostatic Precipitator

C. Anderlohra, L. Brachert, J. Mertens & K. Schaber (Institut für Technische Thermodynamik und Kältetechnik, Karlsruhe Institute of Technology, Karlsruhe, Germany, Laborelec, Linkebeek, Belgium)

Abstract: Wet electrostatic precipitators (WESPs) are considered to be a possible technology for the control of sulfuric acid mist. The performance of a lab-scale WESP was investigated as a precipitator for sulfuric acid aerosol droplets produced under controlled conditions in a pilot plant. It was found that for higher levels of residual SO2 in the flue gas, WESP collection efficiencies were greatly reduced due to aerosol formation inside the WESP. Investigations showed a strong correlation of aerosol emission from the WESP with incoming SO2 concentration and operating voltage. It is suspected that the reactive species produced in the nonthermal plasma of the corona discharge oxidize the SO2 to SO3 which forms sulfuric acid. This causes supersaturation with subsequent homogeneous nucleation and thus aerosol formation.

Emission measurements on tuck boat catalyst systems at Port of Antwerp

Laborelec has won a public tender for measuring the efficiency of the back-up diesel engine catalysts of the Port of Antwerp tuck boats. To do so, our experts will perform various emission measurements (NOX, CO, fine dust, NH3, and carbon hydrogen) before and after the catalyst systems. And this at seven different loads of the tuck boats’ backup diesel engines.

The critical factor in winning the public tender was our strong experience with emission measurements and catalyst systems, for instance in power plants.
