A process for producing methanol and ammonia by generating nitrogen-containing synthesis gas, reacting the carbon oxides and hydrogen incompletely to methanol and passing the unreacted gas to ammonia synthesis, is characterized by carrying out the methanol synthesis in a first, steam-free, stage and in a second stage in the presence of sufficient steam to convert to carbon dioxide substantially all the carbon monoxide not converted to methanol. Methanol can be taken from the systhesis stage as part of the product or can be recycled to that stage, thus limiting its methanol output. |
