Developments in the CO2CRC UNO MK 3 process: A multi-component solvent process for large scale CO2 capture

Abstract

The CO2CRC's UNO MK 3 process is a precipitating potassium carbonate process engineered to capture 90 % of carbon dioxide emissions from large scale emission sources such as power stations and other industrial sources. The UNO MK 3 is expected to have benefits in the following areas; • Low energy of regeneration (2 - 2.5 GJ/tonne of CO2). • Low overall cost, which is expected to be greater than $20/tonne of CO2 avoided less than competing amines. • Low volatility and environmental impact with low emissions, low toxicity and smaller carbon footprint. • Multi-impurity capture of CO2, SOx and NOx with linkage to the global potassium fertilizer chain. These key benefits of the UNO MK 3 proce..
