Urea is produced through the following two-step reactions--

1: 2 NH₃ + CO₂ -> NH₂COONH₄

2: NH₂COONH₄ -> H₂O + NH₂CONH₂ (urea)

If a process to make urea has a feed of 300,000 tonnes/yr, then what is the theoretical target (maximum production) of urea in tonne/yr?

Consider a subsequent reaction in which urea is used to make melamine, by the reaction sequence below. Given this reaction, what is the theoretical target (maximum production) for the produced melamine, in tonne/yr?

3: 6 NH₂CONH₂ (urea) -> C₃N₆H₆ (melamine) + 3 CO₂ + 6 NH₃

If the overall reaction conversion for the urea producing reaction is 95%, and the overall reaction conversion for the melamine producing reaction is 90%, then what are the actual outputs (tonnes/yr) for both the urea and the melamine?

If the losses for the separation of melamine product from any by-products or leftover reactants is 2%, then what is the final actual output (considering both reaction and separation loss) for the final melamine product?
