ID vessel has the appropriate Leff/D ratio. The selected vessel would then be 24 in. I have done some other calculationaccordingto an AIChE (1) paper. MrArt Montemayor I think experience is the main thing in designing. The retention time in a separator is determined by dividing the liquid volume inside the vessel by the liquid flow rate. Set the vapor velocity equal to 75% of the terminal settling velocity. Derivation of the Souders-Brown and Stokes Law Equations. A quick search from the book :Petroleum and Gas Field Processing By Hussein K. Abdel-Aal, Mohamed Aggour, M. A.
