Note:
eparator can by any length, but the ratio of seam-to-seam length to the diameter of the vessel H / Dv usually in the range of 2:1 to 4:1
Calculation choice ratio H / Dv : 4/1The approximate filter capacity have been refered from Fig. 7-16/7-13 _Engineering Data Book ( Approximate Gas Filter Capacity)
