The superior choice with the lowest investment
The present paper describes the preferred technology for large scale methanol production. The benefits of using Autothermal Reforming (ATR) for synthesis gas production will be highlighted with emphasis on single line capacity. A process economic evaluation will be outlined illustrating the advantages of ATR technology compared to two-step methanol reforming at large methanol capacities. The use of an adiabatic top layer in the BWR and the impact on reactor size and investment will be described. The paper also covers ongoing developments of synthesis gas and synthesis technology including reduction of the S/C-ratio in the ATR to further increase single line capacity and reduce capital cost.
