Abstract
A process for manufacturing methanol is disclosed, wherein the pressure in the step of preparation of the synthesis gas is selected equal to the pressure in the step of preparation of methanol from the synthesis gas. The operation efficiency of the process is maintained by recycling the methanol-free recycle stream to the reaction zone for methanol synthesis notwithstanding the lower pressure in the step of methanol synthesis.
