In brief, the chemical design plays an important role in the new factory (workshop or installment) construction, the old factory transformation and the small scale experimental or the medium scale experimental installment. That is, the design is a necessary route for the scientific research achievement transforms for the industrialization big production must pass through the way.
In this article, the way of the carbon briquettes made of synthetic ammonia for a comprehensive design process.The chemical process design including process, layout, piping, process design calculations, the material balance and heat balance. As well as process mapping and simple mapping layout and its main reactor equipment calculated design selection. In addition to its support facilities, such as the condenser, the heat pump and selection. As a result of the lack of experience, it may be not a enough satisfactory design. I hope that the teacher could give guidance.
Key words: Carbonized briquettes; Synthetic Ammonia; Gasification; Desulfurization; Transform; Compression; Synthesis
