[QUOTE="Nowthenblue, post: 7823935, member: 39242"] [SIZE=4]It's chemistry, to make Ammonium Nitrate you have to firstly make Ammonia, to do this in very simple terms you need natural gas ( currently the expensive bit )which is CH[/SIZE][SIZE=3]4[/SIZE][SIZE=4], then you combine it with Nitrogen from the atmosphere ie N ( the free bit ) to make Ammonia NH[/SIZE][SIZE=3]3[/SIZE][SIZE=4]. You lose the C element as Carbon Dioxide as we know. Now you need to make the Nitrate bit, so you make Nitric Acid which is HNO[/SIZE][SIZE=3]3,[/SIZE][SIZE=4] using some more Ammonia in the process, and now you can combine this with your other Ammonia to make Ammonium Nitrate which is NH[/SIZE][SIZE=3]4[/SIZE][SIZE=4]NO[/SIZE][SIZE=3]3[/SIZE][SIZE=4]. All sounds simple as if you can do it with a chemistry set, but high temperatures, high pressures and caltalysts are needed. Urea is slightly different, you still need to start with Ammonia, but then you combine with Carbon Dioxide to make Urea which is CH[/SIZE][SIZE=3]4[/SIZE][SIZE=4]N[/SIZE][SIZE=3]2[/SIZE][SIZE=4]0. [/SIZE] You are partly right, some of the gas is used to power other activities when making N fertilisers, but upwards of 85-90% of the cost of production is the gas. [/QUOTE]
