Hi al's,

What should be the Temp Difference in Divided Wall distillation column?

We have very less temp difference in our Kero/ G oil Fractionator column, 'ie' only 2^0c. while in Design is 10^0c.
If I take in account, temp guage is calibrated and there is no error in guage but difference in Product side is very less. Re-boiler out to column is 352^0c and Bottom Product Gas oil outlet 350^0c.

what can be possible problem is there, can any one put some light on this problem.

thanks

Toor
