Hi all
I am working on graduation project sweetening of Natural Gas at atmospheric pressure
i used CNG cylinder as a source of NG and MDEA (methyl diethanol amine activated with piprazine),
and installed absorber (acrylic with ID 7 cm, 1.5 m height), plastic rashing ring 0.9 cm diameter ,
i have Co2 analyzer and found CNG (inlet feed ) contain 4400 ppm co2
the question is i need VLE( vapour liquid equilibrium data ) for complet matrial balance for the design
i want to understand the diffrence between Co2-MDEA system ,CO2-MDEA-H2o system
and CO2-MDEA-H2o-CH4 system
please any one can teel where to find these data so i can draw relation between Moles of Co2/Moles of Ch4 Vs Moles of Co2/moles of Mdea
