Characteristics of methanol production by the hydroformylation method

Thread Content

1) It is connected in series in the ammonia synthesis process; therefore, it must meet both the process requirements for ammonia synthesis and the requirements for methanol production. Any change in the process conditions of either party will affect the production and operation of synthetic methanol and synthetic ammonia; therefore, necessary supplementary adjustment measures must be implemented during production to ensure that both synthesis processes can proceed simultaneously. 2) Since it is connected in series in the ammonia synthesis process, the process gas after methanol synthesis must be refined before it can be used in the ammonia synthesis reaction. Therefore, the composition of the raw materials after synthesis into methanol must meet the requirements of production. Methanol synthesis gas is produced through partial recycling, and methanol synthesis is not the end stage of the entire production process. 3) Compared with the ammonia synthesis process, since hydroxylamine uses a copper-based catalyst, its resistance to poisoning is poor; therefore, special purification measures must be taken. It maintains the CO and CO2 necessary for synthesizing methanol, while preventing gases such as H2S from entering the system
