    摘要： The invention relates to a method for the coproduction of methanol and ammonia from natural gas involving the following steps: 1. Natural gas (flow 1) , steam and oxygen are mixed with one another in a reactor A during which the natural gas is partially oxidized and additionally reformed with the aid of catalysts; 2. The gas mixture removed from reactor A is split into a flow (flow 2) for synthesizing methanol in a unit E and into another flow (flow 3) for producing hydrogen; 3. The carbon monoxide present in flow (flow 3) for producing hydrogen is converted into carbon dioxide inside reactor B with the aid of catalysts and intermediate cooling stages; 4. Remaining impurities such as methane, traces of carbon monoxide and argon are washed out in a cleaning unit D, and hydrogen (flows 6, 8) is fed to the methanol synthesis in unit E and to the ammonia synthesis in unit F; 5. The methanol synthesis gas (flow 7) is converted into methanol (flow 9) with the aid of a catalyst, and the methanol is brought to the required level of purity by distillation; 6. The ammonia synthesis gas,(flow 8) is compressed in unit F and converted into ammonia (flow 10) with the aid of a catalyst, and the ammonia is separated from the recovered synthesis gas by partial condensation.

    摘要： The invention relates to a method for the coproduction of methanol and ammonia having the following steps: 1. Natural gas (stream 1), steam and oxygen are mixed together in a reactor A, wherein the natural gas is partially oxidized and further reformed with the aid of catalysts, 2. The gas mixture taken from reactor A is divided into stream (stream 2) for the methanol synthesis in a unit E and another stream (stream 3) for hydrogen production, 3. The carbon monoxide present in the stream (stream 3) for the hydrogen production is converted into carbon dioxide with aid from catalysts and intermediate cooling stages, 4. Remaining impurities such as methane, traces of carbon monoxide and argon are washed out in a purification unit D, and hydrogen (streams 6, 8) is fed to the methanol synthesis in the unit E and the ammonia synthesis in a unit F, 5. The methanol synthesis gas (stream 7) is converted into methanol (stream 9) in a unit E with the help of a catalyst, and the methanol is brought to the required purity by distillation, 6. The ammonia synthesis gas (stream 8) is compressed and with the help of a catalyst is converted to ammonia (stream 10) in unit F, and the ammonia is separated from the recovered synthesis gas by partial condensation.
