The supply of conventional amines such as monoethanolamine (MEA), methyl diethanolamine (MDEA), and 2-amino-2-methyl-1-propanol (AMP), can meet current demand. The manufacturing process is well established and there is extensive experience. However, there are few large-scale commercial suppliers. This may lead to bottlenecks or monopolisation of the market at the projected scales. Manufacturing relies on alkyl oxides and ammonia; these chemicals require ASU, and hydrogen, both of which we have identified possible bottlenecks for. The production of alkyl oxides such as ethylene oxide, and propylene oxide require silver-based catalysts. We address the issues associated with catalysts based on metals in limited supply below.
