scale ammonia production plants throughout the industrial world, some of which produce as much as 2000 to 3000 tons per day of anhydrous ammonia in liquid form. The worldwide production in 2006 was 122,000,000 metric tons. China produced 32.0% of the worldwide production followed by India with 8.9%, Russia with 8.2%, and the USA with 6.5%.
A molar ratio between hydrogen and nitrogen of 3 to 1 is optimal for ammonia production (Twigg, 1996). This ratio is achieved by controlling the flow of N 2 stream. The synthesis reaction is exothermic; therefore, the generated heat can be used initially to preheat the feed reactor and, then, it is recovered to produce additional power in GT-4.
Flowchart is one of the most widely-used diagrams that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows.

The ideal temperature is 450C. According to le chatelier''s principle, if you increase the temperature the smaller the amount of products release. However, if you decrease the temperature, this slows down the rate of production. 450C is a compromise temperature as it produces a medium yield at a medium rate.
