Performance Analysis of a Laboratory Carbon Dioxide Absorption Setup Using Aqueous Monoethanolamine Solution

Abstract

Electricity Generating Authority of Thailand is the largest power producer in Thailand, owning and operating power plants at 45 sites across the country. With forthcoming global climate crisis, current effort in improving energy efficiency and adopting alternative sources of energy may not be sufficiently rapid. Post-combustion carbon capture with amine based solutions is a well-established technology and offers a further option in reducing carbon dioxide emissions from existing power plants. In this work, a laboratory-scale, amine based CO2 absorption setup was developed and its performance test was carried out, using Monoethanolamine at 30% concentration handling flue gas conditions similar to those from Mae Moh power plant. The preliminary results revealed high carbon capture efficiency (>97%) could be achieved in a continuous operation.
