Summary post on energy-saving and power-saving optimization processes for ammonia synthesis production

Thread Content

To summarize, our company’s technologies for energy conservation and power saving in ammonia synthesis are as follows: 1. The use of high-efficiency tubular absorbers for gas washing, cooling, and dust removal enables an effective improvement in the efficiency of these processes, reduces the amount of cooling water required, enhances the purity of the gases, and simultaneously achieves energy savings. 2. The use of high-efficiency tubular absorbers for desulfurization in units with high sulfur content enables an effective improvement in desulfurization efficiency, increases the sulfur capacity of the desulfurization liquid, resolves the issue of resistance associated with packed towers, reduces the volume of desulfurization liquid that needs to be circulated, and thus achieves good energy-saving results. 3. By combining a high-efficiency, low-resistance gas-liquid separation honeycomb structured packing with a low-resistance, controllable-level tray distributor, a modular packed tower can effectively improve absorption efficiency and reduce the resistance of the packed tower, thereby achieving good energy-saving results. 4. The steam injection technique in a stepped manner, both from above and below, in the fixed-bed gas generation process can effectively reduce the operating resistance of the fixed-bed furnace, increase the gas production per furnace, enhance gas production efficiency, reduce char formation, and improve the proportion of useful gases. The coal and steam saving effect of the briquette gas production process is significant. 5. The use of differential pressure technology for the energy recovery of high-pressure hydraulic energy within the system yields significant power-saving effects (utilization in medium-pressure decarburization pumps and turbines, as well as in high-pressure copper washing differential pressure pumps). 6. The use of evaporation cooling technology in place of water coolers, along with the elimination of large-scale system circulation, effectively improves cooling efficiency and thus achieves energy savings. 7. The technology of using waste heat within the system for ammonia absorption refrigeration as a substitute for ice machines enables effective utilization of this waste heat, reducing the system’s refrigeration energy consumption by around 70%.
