Synthetic Ammonia Energy Saving Renovation Project Activity Poster

The main construction contents of the energy-saving renovation project of the alcohol-ammonia production system are: 1. Energy-saving optimization of the 60,000-ton combined alcohol production line. Add one Ф1200 methanol tower to replace the original two Ф800 methanol towers ； Utilize one methanol tower of the original combined alcohol production system to replace one Ф500 tower and one Ф600 tower in the original methane chemical section. ； A new set of 1500Nm3/h synthetic ammonia purge membrane separation and hydrogen extraction device was added. After the transformation, 3,938 tons of standard coal can be saved every year. 2. Transformation of heat recovery system in gas production process: Transformed 6 gas waste heat recoverers in the alcohol and ammonia production gas section of the entire plant into high-efficiency heat pipe recoverers ； The normal pressure jackets of 22 gas generators were transformed into pressurized jackets, and 11 normal pressure steam drums were transformed into pressurized steam drums, thereby improving the low-level heat energy recovery rate of gas and the conversion rate of the carbon layer in the furnace. Through the transformation, 4,680 tons of standard coal can be saved annually. 3. Optimization and transformation of decarbonization system: Modify the procedures of the three pressure swing adsorption decarbonization systems in the entire plant, add a replacement recovery process, reduce the CO2 content in the decarbonized gas, and reduce the energy consumption of hydrogen production. Through the transformation, 5219.2 tons of standard coal can be saved annually. This post was last edited by jindin312 on 2009-2-20 20:32 ]
