Two demand scenarios were investigated: BAU and LC. As shown in Figure The BAU demand scenario consisted of olefin, aromatics, and methanol demands of 11.8, 10.9, and 15.5 Mt/y in 2050, respectively. The LC demand scenario consisted of olefin, aromatics, and methanol demands of 7.2, 7.1, and 14.9 Mt/y in 2050, respectively. This was in contrast to the demands of 12.8, 12.3, and 1.5 Mt/y in 2020 for the same chemicals. Methanol demand increased significantly by 2050 to serve as an intermediate in the production of olefins and aromatics via the methanol-to-olefin (MTO) and methanol-to-aromatics (MTA) processes.
