Technical Seminar : Condition monitoring of turbine lubricating oils

Oil varnishing, oxidation and phosphate ester degradation are among the most threatening problems for both gas and steam turbines. Fortunately, there are ways to detect and remedy these issues efficiently and effectively. Discover the best available lubricating oil analysis techniques and contamination control procedures during the two-day seminar ‘Condition monitoring of turbine lubricating oils’ in Singapore. Applying these techniques will enable you to improve the reliability and availability of your equipment.

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.

Biomass Counts

The importance of biomass as part of a strong and competitive low carbon economy is highlighted in a major new campaign initiative sponsored by the European Biomass Association AEBIOM, of which GDF SUEZ is a member, represented by Laborelec.

The Biomass Counts campaign argues that biomass will continue to be a vital component of our energy mix into the medium and long term. It turns the spotlight on what is needed to assure the continued growth of the bioenergy sector.

Among other measures the initiative calls for an EU action plan for the heating and cooling sector, with an agreed strategy for legally binding sustainability criteria. For more information, please visit www.aebiom.org.

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.

End is in sight for EnAlgae (European algae project)

2015 is the final year for the EnAlgae project, and after four years’ study, experimentation and dissemination the end is now very firmly in sight. Partners working on the project are busy finishing off reports and working on presenting their final conclusions. This will come to fruition when the project holds its final close-out conference in the Autumn. The event is due to take place in Brussels on 29th and 30th September. Further details on this event will be published in due course.

Laborelec is contributing to EnAlgae by helping to define and develop the decision support tool, a major output of the project. The tool will be used provide investors and policy-makers with the necessary means to tailor algal-based energy solutions to particular physical and social conditions within NWE.
