浅析制冷系统的操作对氨合成生产运行的影响

Influence of refrigeration system operation on ammonia synthesis

氨冷凝温度的高低将决定氨合成塔进口氨含量的高低,也将直接影响合成氨反应的效率。影响冷凝温度的因素被分析,加强冷凝温度的控制降低入口氨含量,有利于提高氨合成效率。

3-hydroxypropionic acid （3-HP） is a potential valuable chemical, for example, can be used to synthesize biodegradable thermoplastic resin and 1,3-propanediol. The research progresses in the production methods of 3-HP, including the chemical and microbial fermentation routes, were introduced. Through comparing the advantages and disadvantages of the two production methods, the chemical synthetic route was considered to be more competitive and have a brighter future than the microbial fermentation route.
