Trends in an Absorption Column through Mass Transfer Coefficients

A study was conducted to measure the values of m.t.c and N an absorption column. Values were in range 10-5, while those 10-7. The trends with variables confirmed previous studies. However, they not m.t.c. Pressure variance suggested as reason. Error assessed at a percentage 15% for m.t.c, under 2% pressure. Using other methods than only measuring concentration solute Hempl apparatus recommended.
