Inlet mole flowrate:
Tri-Olein =8.201067216(Kmolh), water =74.08344816(Kmolh)
Densities At 250C :
Density of Tri-Olein (L):0.753(gcm3), Density of Water (L):0.800(gcm3), Density of Glycerol(L): 1.092
(gcm3), Density of Oleic-Acid (L):0.734(gcm3), Density of Mono-Olein (L):0.813(gcm3), Density of
Di-Olein(L): 0.818(gcm3).
Rate constants are:
Step 1(forward): Kf=5.0010-3(m3moles), Step 1(reverse): Kr=2.1310-2(m3moles)
Step 2(forward): Kf=8.0910-0(m3moles), Step 2(reverse): Kr=6.1210-0(m3moles)
Step 3(forward): Kf=1.95100(m3moles), Step 3(reverse): Kr=5.5210-1(m3moles)
Note: the constant rates of reactions are taken from different reference. If it is not suitable find the correct
values
Assume constant pressure within the reactor. The reaction is isothermal. Constant volume.
