Assessing atmospheric emissions from an amine-based CO2 post-combustion capture processes and their impacts on the environment: a case study
1st May 2014
This two volume study was commissioned by the Global CCS Institute to expand knowledge on the environmental impacts of the capture process of carbon capture and storage (CCS). The study measured actual emissions and explored a case study into air quality at the AGL Loy Lang PCC Plant in Victoria, Australia.
This document summarises the major outcomes of the CSIRO-led investigation into the potential air quality impacts of amine-based post-combustion carbon capture (PCC) technology.
Volume 1. Measurement of emissions from a monoethanolamine-based post-combustion CO2 capture pilot plant
This report describes the comprehensive experimental investigation of emissions concentrations of selected PCC liquors and process gas streams at the AGL Loy Yang Power Station using the CSIRO Loy Yang pilot-scale post-combustion capture (PCC) plant (LYPP). The benchmark solvent, monoethanolamine (MEA), was used to capture CO2 from the process gas of the Loy Yang coal-fired power plant. The experimental study focused on applying, evaluating and, where required, further developing current stack sampling and analytical techniques to identify the major chemical components existing in the process.
Volume 2. Atmospheric chemistry of MEA and 3D air quality modelling of emissions from the Loy Yang PCC plant
This report describes an experimental and modelling study of the impact of ethanolamine (MEA) emissions from the CSIRO Loy Yang pilot scale PCC plant. A chemical transport modelling system was used to simulate the likely impact of retrofitting a PCC installation to Loy Yang power station. A representative month (March 2005) was selected on the basis of having many of the atmospheric process of relevance to the chemical transformation of MEA and near-source plume strikes from the power station.
