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.

Wood pellets and biomass: Health and safety first

Wood pellets and biomass cannot be considered entirely harmless in the work environment. This is the key message of a recent article in Bioenergy International. In the article, Yves Ryckmans, Chief Technologist Biomass of Laborelec, discusses the potential health risks for staff exposed long term to wood dust.

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

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.

Initiative Wood Pellets Buyers has been transformed into Sustainable Biomass Partnership (SBP)

logo SBP sustainable biomass partnerMain reasons are that the focus will not be only on wood pellets but on solid biomass as a whole. SBP has got a new governance system with new board, director and sounding board. Not only biomass buyers are contributing to SBP but also specialists in corporate social responsibility and experts in forestry.

Optimizing combustion processes throughout Europe

Combustion inefficiencies, slagging, and elevated emissions of NOX and CO are common problems resulting from imbalances in coal-fired power plant boilers. Laborelec uses mobile EUtech EUflame 2D sensors, a two-dimensional temperature measurement system, to visualize such imbalances and optimize the combustion process. The sensors were already successfully implemented in various power plants in Belgium, Germany, and other European countries.

Training Course Combustion Technology on GE/SIEMENS/ALSTOM Gasturbines

On request of the ONG, Mr. Hannes Laget of Laborelec organized a training session on combustion in Gasturbines in Dubai. There was a 2 day session for GE machines and a 2 day session for Siemens/Alstom machines.

During the first day of each session the basics of combustion technology were addressed with special attention to the design philosophy of DLN combustion systems and the impact on emissions. Possible combustion issues such as combustion instabilities and flash back were explained. Also the fuel specifications, combustion chemistry and combustion dynamics were treated during that first day. The second day the focus was on the specific design and control philosophy of the GE, Siemens and Alstom machines. Special attention was given to why and how to follow up the tuning of the combustion system.
