Gas Cleaning

GC001: Identify novel protectors for candle filters coupled with Pall's CPP unit and identify sorbents to co-remove gaseous contaminants

Particulate cleaning at high temperatures is a critical unit operation required for the development of advanced IGCC and fuel cell power generation cycles. In the temperature range covering warm to hot gas cleaning, key issues to be addressed include: identification/prevention of corrosion in candle filters, impact of tensile stress and pulse cleaning techniques on the filter media, and opportunities to combine the removal of gaseous contaminants through injection of sorbents and condensation of volatile species such as alkalis and trace elements on the filter cake formed in candle filters. This project addresses many of the above mentioned issues with additional potential to develop collaborative activities with Pall to evaluate their coupled pressurised pulse (CPP) cleaning technique for candle protection.
