For the production of synthetic ammonia from natural gas, is the Topsoe process more widely used or the KBR process?
Thread Content
According to a document on the ammonia synthesis process, since 1990, the Topsoe process has accounted for over 50 percent of all cases. Why is that?
The ammonia synthesis plants in our country that use natural gas and light oil as raw materials are mainly large-scale facilities. Among the large-scale ammonia synthesis plants that have been built to date, 14 use natural gas as a raw material, while 6 use naphtha. These plants employ the Calog process, the Calog-TEC process, the Danish Topsoe process, the energy-efficient AMV process, and the American Brown process. Using natural gas as raw material (traditional process), the average energy consumption per ton is 36.66 GJ, with the lowest value being 32.84 GJ ； Using natural gas as the raw material (energy-saving process), the average energy consumption per ton is 34.12 GJ, with the lowest value being 31.05 GJ ； The average energy consumption per ton using naphtha as raw material is 38.68 GJ, with the lowest value being 37.01 GJ.
In recent years, KBR has likely held a dominant position; the two largest natural gas-based fertilizer plants in the country use KBR’s technology, and for most new projects abroad as well, KBR’s process is employed
