(How much steam is consumed per theoretical ton of ammonia-copper washing?)
Thread Content
How much steam is consumed per theoretical ton of ammonia-copper washing? How is the cost of synthetic ammonia calculated?
The heat consumption for ton of ammonia-copper washing is 630,000 kcal； Equivalent standard coal is: 900 kilograms, and equivalent fuel coal is 1167 kilograms. I’m sorry, there was a calculation error: 630,000 kca is equivalent to 90 kilograms of standard coal, and 126 kilograms of fuel. This post was last edited by *aoye613 on 2009-2-21 13:36]
The costs associated with the copper washing process, including electrolytic copper, liquid ammonia, acetic acid, steam, and electricity, are as follows: (Extracted from data on energy consumption in small nitrogen fertilizer production) Electrolytic copper: 0.1819 kg/NH3; Liquid ammonia: 8 kg/tNH3; Acetic acid: 0.2423 kg/tNH3; Steam: 300 kg/tNH3; Electricity for copper pumps: 20 KW•h/tNH3; Electricity for freezing: 11 KW•h/tNH3
