Development and Evaluation of a New Amine Solvent at the Mikawa CO2 Capture Pilot Plant

Decreasing CO2 Emissions from coal fired thermal power plants is a critical issue in the world. Toshiba designed and built the CO2 capture pilot plant at Mikawa coal fired thermal power plant in 2009. Following this, we have developed not only an efficient CO2 capture system but also amine solvent that captures CO2 using live flue gas from the thermal power plant. After compiling the laboratory results, we decided to introduce the new amine solvent to the Mikawa pilot plant in order to evaluate the overall performance of this new solvent at 10t/d-scale test. We prepared the new solvent and subsequently stared to optimize the operation conditions, monitored the life performance and investigated the amine degradation. As a result, we confirmed the regeneration energy of 2.4GJ/t-CO2 with 90% capturing CO2 by 12%-CO2 concentration live flue gas from coal fired thermal power plant.
