Recent Developments in the UNO MK 3 Process–A Low Cost, Environmentally Benign Precipitating Process for CO2 Capture

Substantial progress in the development of the UNO MK 3 process and it's cost reduction capabilities has been made since previously reported [1] . In particular, the recent results of two pilot plant trials of the process continue to demonstrate and confirm the major features of the UNO MK 3 process: Low overall cost (up to 50% less than the best amines) Multi-impurity capture and production of valuable by-products (no degradation products) Low energy of regeneration (less than 2.5 GJ/T CO 2 ) Low volatility and environmental impact (SOx and NOx converted to fertilizer products) A good fit with existing global potassium markets (no additional potassium required) These new results are groundbreaking in terms of advancing the process; with no major barriers evident for scaling up the process from the current pilot scale (TRL 5) to larger scale demonstration (TRL 6/7) over the next few years.
