Equilibrium flash calculations
Equilibrium flash calculations
(OP)
DEAR CHEM.ENG
I have a sweet feed gas of the following components;
C1,C2,C3,IC4,nC5, CO2(0.0005mol%), N2 (0.0254mol%)and H2S(0.000004% MOL), feed into an absorber using a lean TEG of 98.7 wt % as a solvent.
Im struggling to calculate the F=L+V= 1 , i tried to use Coulson and Richardson's Vol.6, Gas conditioning and processing vol.2 (Campbell) and others.
I got K values (for all components except H2O and TEG) at 71 bar and 38C by interpolation from Campbell vol.1.
Would you please guide me to the absorber flash calculations????

any suggestions????

In the university we had a thermodynamics book by Smith Van Ness with many numerical examples.

I still have an old Excel file which might help you navigate the SVNA text, if you buy that book. If you're interested I'll e-mail it. The procedure is far too complicated for me type out.
Maybe you can validate your results in a way that's faster than doing the hand-iteration method?

Amphoteric I appreciate if you can please send me that excel. sheet and I will have a go through.

I have attached my old calculation to this post. It may help you formulate a strategy to tackle your problem. Please note the disclaimer.
