glycol coil sizing

[nitin6]

to design a coil inside a glycol absorber(top) to cool
the inlet glycol by colder natural gas stream moving up the
column in a glycol dehydration system.

So what is your question? If the question is how much area is required?, calculate the internal and external heat transfer coefficients and use that to calculate the area required. The duty is set by the glycol flow rate and the amount of cooling you want, the gas outlet temperature is determined from an overall energy balance (Q from glycol = Q gained by gas).

my question for my earlier forum was how to do sizing of
a coil to be located inside a glycol absorber.Iam looking
for suitable calculation procedure.Since the coil is in the
top section above the bubble cap the fluid outside coil is
natural gas.
Additionally i have another coil at the bottom of column.
The absorber has two sections, above gas inlet is the absorption section and below gas inlet is an integral scrubber section.Oil,condensate and water collects in the bottom and is continously drained.A bottom glycol coil runs through this section.
Presently i am looking for a simple calculation procedure
to size my coil and estimate total no of turns required.

This should be a straight forward heat transfer calculation to determine the surface area required, then determine the number of coils to achieve the required area. A good heat transfer text will help you with this (try Process Heat Transfer by DQ Kern)
