摘要:
A process for co-production of ammonia, urea and methanol from natural gas, comprising the steps of (a) producing a synthesis gas by simultaneous feeding natural gas to an au-tothermal reformer (ATR) and to a steam methane reformer (SMR), the two reformers running in parallel, (b) feeding air to an air separation unit (ASU), where the air is split into oxygen, which is fed to the ATR, and nitrogen, (c) subjecting the synthesis gas from the SMR to a water gas shift, (d) removing the carbon dioxide from the synthesis gas from step (c) and leading it to urea synthesis in a urea synthesis unit, (e) combining the hydrogen-rich gas from step (d) with the nitrogen from step (b), removing catalyst poisons from the gases and leading the gas mixture to ammonia synthesis in an ammonia synthesis unit, (f) optionally removing part of the carbon dioxide from the syngas from the ATR in step (a) and leading it to urea synthesis in a urea synthesis unit and (g) leading the syngas from step (f) to the methanol synthesis unit, wherein synthesis gas from step (a) may be led either from the ATR outlet to the SMR outlet upstream from the shift stage or the other way.
