Ammonia Process with Nonlinear Alternative Specifications: Simultaneous Solution (Reklaitis [1983], p. 273) We
have solved this problem using the sequential modular
approach with a single-variable search; see Chapter 3,
Problem 3.17.
Starting with Problem 4.10, suppose the splitter split
fraction α6
is adjusted so that the combined reactor feed gas
contains 18 mol % CH4. Calculate all flows in the process.
Again, assume a basis of 1000 mol/h for the feed stream
(stream 1). Solve this problem using the simultaneous solution approach.
Solution Hint
This problem can be confusing to solve, especially as to
the best way of incorporating the nonlinear equations into the
