CO₂ ABSORPTION ENHANCEMENT USING METHANOL-BASED NANOFLUIDS

다국어 초록 (Multilingual Abstract)

Recently there are growing concerns that anthropogenic carbon dioxide (CO₂) emissions cause the global warming problem. In this study, the suspensions of Al₂O₃ nanoparticles in methanol (called the nanofluid) are developed and estimated to apply it to absorb the CO₂ in AGR (acid gas removal) system. The continuous removal system is an acrylic tray column with nine plates. The column is a sieve tray type which has flat perforated plates where the vapor velocity keeps the liquid from flowing down through the holes. The absorption experiments have been carried out employing a tray column, where the CO₂ gas and methanol liquid are counter-current flow. The test section is equipped with two mass flow meters to measure the absorption rate. We obtained an enhanced absorption rate (compared to pure methanol absorbent) of 26.9%, 101.3% and 251.5% for the concentrations of 0.005, 0.01 and 0.05vol% respectively.
