IntroductionINTRODUCTION TO HORIZONTAL VESSEL SIZING PROGRAMProgram Name0.0Version0Revision0AuthorR AspinallCLICK ON HIGHLIGHTED BUTTONSDate31-Dec-99PurposeLevel Control GuidelinesThis program is designed to assist with sizing of 2 phase and 3 phase horizontal separators.The following liquid levels are offered only as an approximate guide.This program is based on the guidelines for horizontal separators in API 12JWhere project specific level control data is available, the following may be ignored.For explanation of liquid levels click on boxes highlighted in yellow.Instructions for use1. Input required process data in the 'Data Input' sheet:3 Phase Separator- Fluid Mass Flowrates & Densities- Oil Viscosity- Separator operating pressure- Separator Type - ie 2 or 3 phase- Separation Device- Vessel Aspect Ratio (Length/ Diameter)- Level constraints (See diagrams opposite For Guidelines)There are 2 options for entering liquid level constraints:1) Default level constraints may be chosen by clicking on the 'Default Level Constraints' button2) User specified level constraints may be entered directly- Required Oil & Water or liquid (for 2 phase separators) Residence Times- Max allowable rhov2 for inlet/ vapour outlet nozzles and max allowable velocity for liquid outlet nozzle2. Goto the 'Calculations (1)' sheet by clicking on the button at the bottom of 'Data Input Sheet'3. Input an initial guess for the vessel diameter based on the estimated diameter andenter maximum interface and liquid levels as a percentage of the vessel diameter.4. Hit the 'Execute Program' button and check residence times to see if requirements are met.( Note1: the calculated default liquid levels are based on the user input level constraints)( Note2: the program will give a warning if input dia is too small (based on user input level constraints))2 Phase Separator5. If either the API criteria or other criteria is not met adjust dia and/ or maximum Oil/ Interface levelsand rerun program1. When actual liquid levels are known, these may be entered by clicking onthe 'enter liquid levels' button in the 'Data Input' sheet. This will take the user tothe main calculation sheet and the liquid levels can be entered in the highlighted cells.Once these are entered, go back to the Data Input Sheet and complete input.Goto 'Calculations (1) sheet' and enter the vessel diameter. There is no need to executethe program since this calculates liquid levels based on the level constraints.2. The water outlet nozzle is fixed @ 150mm above the vessel base. This may be adjusted to auser preferred value by overwriting the default value in 'calculations(2)' worksheetLimitations1. Does not take into account vessel heads therefore the separation volume used in calculations is conservativeFEEDBACK: All feedback should be sent to the Owner (Assigned Custodian): - see Revision Status sht.
