Species Removal via the Inspection of Rates

Several methods have been suggested for the identification of redundant species. An early approach was introduced by Frenklach et al. (Frenklach et al. 1986 Frenklach 1991) who investigated the elimination of species from a detailed 

Valorani et al. (2006) used the CSP method (see Sect. 6.4) for the identification of redundant species. They first define important species and check in which modes they are present. Reaction steps are then identified that have a significant contribution to these modes. These reaction steps may include further species, which will be considered as necessary species. Using an iterative procedure, the number of necessary species is continuously increased until at the end of the process no more important reactions are found.
