Abstract [en]

In bio-based methanol production approximately 60% of the biomass energy content is converted into methanol, the remaining part can be recovered as thermal heat. Efficient utilization of the thermal heat is difficult in stand-alone methanol plants. The overall efficiency is to a large extent dependent on the further conversion of power due to the significant quantity of excess heat. Heat can be recovered in a steam cycle but due to poor steam data energy efficiency is low. This paper therefore proposes the integration of a natural gas fired gas turbine. Simulations of the hybrid cycle in methanol production have shown good improvements. The total electrical efficiency is increased by 1.4-2.4 percentage points, depending on the fuel mix. The electrical efficiency for the natural gas used in the hybrid plant is 56-58%, which is in the same range as in large-scale combined cycle plants. A bio-methanol plant with a hybrid power cycle is therefore a competitive production route for both biomass and natural gas.
