pyChemEng

pyChemEng is a Python package for understanding and representing multiple adsorption and kinetic models in the chemical thermodynamics spectrum. This project is an initiative considering research scientists for the unequivocal representation of the models with all the useful information.

Examples

The variables x and y are established initially as a list. Later, the function isotherm is called with all the parameters set to True for the graphs that could be produced with the function. The same procedure adheres to the kinetics function.

The following is a precedent for implementing the package for adsorption isotherms models. All the available outputs are called for the current example.

  plot    -->  Varying adsorption (i.e., y) with concentration in the solution at equilibrium (i.e., x)     
  comp    -->  Predicted values vs experimetal values 
  res     -->  Residuals 
  std_res -->  Standardised residuals

  from adsorption import *

  x = [0.36, 1.26, 2.69, 3.95, 5.93, 8.98, 16.89, 26.23]
  y = [3.76, 6.15, 12.35, 14.49, 17.39, 21.96, 22.93, 23.17]

  isotherm(x,y,ad_model=langmuir,plot=True,comp=True,res=True,std_res=True)

Currently available adsorption isotherm models in this package are:

  langmuir
  freundlich
  toth
  sips
  temkin
  dubinin

The following is a precedent for implementing the package for adsorption kinetic models. All the available outputs are called for the current example.

  plot    -->  Varying adsorption (i.e., y) with time (i.e., x)     
  comp    -->  Predicted values vs experimetal values 
  res     -->  Residuals 
  std_res -->  Standardised residuals

  from kinetics import *

  x = [61.60,118.84,178.81,237.37,299.17,414.08,540.83]
  y = [7.77,10.02,11.45,13.09,13.91,14.32,14.32]
  
  kinetics(x,y,Kn_model=pfo,plot=True,comp=True,res=True,std_res=True)

Currently available adsorption kinetic models in this package are:

  pfo
  pso
  elovich
  sips
  temkin
  dubinin

pfo --> Pseudo First Order

pso --> Pseudo Second Order
