TEG absorber stages

[JAIFAR]

Dear Engineer:

Would someone help me in solving the number of TEG absorber number of trays?!! The available equilibrium data for Natural gas -water -TEG system from M.S.Worley are in the table below :

TEG concentration Lb H2O/Lb TEG Equilibrium
(% w/w ) water content
lb H2O/mmscf
99 0.0101 1.24
98 0.0204 2.5
97 0.0309 3.88
96 0.0417 5.25
95 0.0526 6.7
90 0.1111 13.33

I have an absorber of 71 bar and 40% tray efficiency.

I'm struggling on how to plot the above data to count for number of absorber trays???

If you can't solve your string of TEG question by buying a GPSA handbook of google McCabe-Thiele
