Chemical Process Simulation
A guide to simulation techniques for chemical engineering. Covers flowsheeting, partitioning and tearing a set of equations and networks of process units, maintaining sparcity of matrices, convergence promotion methods, and available data banks of properties. Reviews background information on model formulation and numerical methods, and applications of graph theory in synthesising networks.
