Venting Requirement for External Floating Roof Tank

May 23,2007 API 650 tanks automatic bleeder vent#0183;In my opinion,other than a bleeder vent to allow in breathing and out breathing while the roof is setting on its legs,there's no much more that I would do.As far as the bleeder vent(s) go,maybe someone can assist in the calculations for size and number.I have never seen one larger than 8 and never more than three per tank or less than 1.Venting Guide for Aboveground Storage TanksFind tank size on Table C which can be found on page 7.Table lists wetted area and CFH for common sized tanks.For a 274L x 130W x 65H (22' I O'L x 10-1 x 5'5H) tank wetted area = 61 2 sq.ft.and required vent capacity = 396,320 CFH.Proceed to Step 4.STEP 2 Wetted Area Table If tank size is NOT listed on Table C,page 7,wetted areaVenting Calculation - Outbreathing - EnggCyclopediaVenting Calculation for Outbreathing due to liquid movement into the tank.As per API 2000,the outbreathing flow should be sized to correspond to maximum possible liquid flow into the tank.Depending on the flash point and normal boiling point of liquid contents at the tank operating pressure,the venting requirements are different.
