Balancing Chemical Equations

solvesimul.m can be easily adapted to solve more equations but as it stands it will solve 2 unknowns in 2 equations (1 non-linear and one linear).To solve equations of this form... a*x + b*y = A (1) a1*x^2 + b1*y^2 = B (2)...with fsolve (used by solvesimul.m) you need to rewrite them so that they...

It estimates the Newton Raphson optimization procedure for (m) unknowns of (n) non-linear equations. In case no Jacobian vector is presented, then the initial Jacobian vector is estimated by Broyden Method (multivariate secant approach) and it is then updated using the Sherman Morrison...

The five programs provided solve several process design problems. These examples were originally provided as applications of process design optimization by Edgar, Himmelblau and Lasdon in their excellent book entitled Optimization of Chemical Processes, McGraw-Hill International Edition, 2001....

We use the SRK equation of state to compute the correction factor due to gas-phase nonideality as a result of the high pressure applied in the ammonia synthesis. We also compute the extent of reaction. Plots of these two quantities versus pressure for temperature equal to 800K are presented. The...

This function solves the linear fractional-order differential equations (FODE) with constant coefficients. The short memory principle has not neen used here, so the length of input signal is limited to few hundred samples. The parameters of the FODE (in its standard form) are the inputs of this...

The program allows one to choose the best reactor setup among three alternatives: (1) a plug flow reactor with recycle, (2) a combination of a plug flow reactor and a stirred tank reactor in series and (3) two stirred tank reactors in series. This problem was solved graphically by O. Levenspiel...

PID control over the exit raffinate composition (x5) of a five stages column is obtained by changing solvent flow rate (G). The set point is equal to 0.1. The model equations include backmixing effects. This problem is solved using Berkeley-Madonna in Chemical Engineering Dynamics, Ingham et al.,...
