Flare Ko Drum Sizing by Api 521 SWP008: 'File:///conversion/tmp/scratch/480402124.xls'#$sheet1

This document contains calculations and sizing parameters for 7 different flare knockout drum runs according to API 521. It includes information on vessel tag number, run number, liquid and gas densities/viscosities, sizing parameters like CRe^2 value, liquid and gas flow rates, drum dimensions, drainage volume, liquid accumulation areas, residence times, vapor accumulation areas, vapor velocities and minimum drum lengths required to meet design criteria. The minimum drum length to drum length ratios show that the length criteria is met for all 7 runs.
