InstructionsSEPARATOR SIZING SPREADSHEETREV:ADATE:February 1999I.PURPOSEThe aim of the separator sizing spreadsheet is to assistthe designer in saving valuable time resources by providing auser-friendly spreadsheet in Excel to calculate sizingparameters for both horizontal and vertical separators.II.DESIGN BASESA. Gas residence times are calculated using the normal liquid levelas the basis. In the case of the horizontal separatorwith weirplate partition, the basis used is the height ofthe weir for the gas volume. Dished end volumes havebeen neglected for the gas residence time calculations.B. K-values to be used as input data for the spreadsheetsare found in the GPSA Handbook(10thedition), figure 7.9 on page 7-7.The K factors must be converted to m/s to be placed intothe spreadsheet. The purpose of the K-factor is fordesigns which include woven wire demisters. Demisters(mist extractors) can significantly reduce the requireddiameter of vertical separators.C. Dished-end volume calculations have been included forboth vertical and horizontal separators. For thevertical separator, an option is provided for choosingbetween semi-ellipsoidal and semi-hemispherical ends,however, for all horizontal separators, the ends havebeen assumed to be semi-ellipsoidal.(Reference: GPSA Handbook section 6 Fig 6.21-6.22)D. Other standards used in calculations includeAPI RP 521 Section 5.4.2 and calculations for thestandpipe were from EXXON Criteria in Design Practice 5B(September 1978).III.METHODThe following procedure is a step-by step outline for thedesigner.A. Step One: Choose the type of separator required.The separators available in this spreadsheet include:-Horizontal, 3 Phase, with boot-Horizontal, 3 Phase, no boot, weirplatepartition.-Horizontal, 3 Phase, no boot, standpipefor condensate.-Horizontal, 2 Phase-Vertical, 2 PhasePage 1 of 3SEPARATOR SIZING SPREADSHEET - INSTRUCTION NOTESVertical separators are usually selected when the gas-liquid ratio is high or total gas volumes are low.Horizontal separators are most efficient where largevolumes of total fluids and large amounts of dissolvedgas are present with the liquid. For more information onseparators please refer to GPSA Handbook, Section 7.B. Step Two: After the separator type is chosen, begininputting data into the cells of the spreadsheet whichhave blue italicised text. Do not write in cells whichcontain red or black text! Input data is summarised inthe top left hand side of the spreadsheet. Feedflowrates, properties and nozzle velocity specificationsare entered in this section. Data on vessellength, diameter and liquid levels are entered on thevessel sketch. Unknown values need to be assumed,otherwise errors will occur in the results.C. Step Three: When all blue cells are filled - including thedimensions on the sketch, the spreadsheet will calculateall relevant values. The intermediate calculations canbe found below the sketch. Final output results arelisted on the sketch and in the top section of thespreadsheet. All formulae are in red text.D. Step Four: Before final outputs can be used, warningsmust be considered. Warnings appear in bold green text,and will appear as "OK" when there is no warning present.If a warning does exist, try to change the relevantparameters to remove or reduce the warnings. Thesegenerally relate to liquid levels in the separator and gasresidence times.E. Step Five: Check your units!!! The units defined on thespreadsheets can be found in the nomenclature section.The notes section may also assist with understandingwhich units to use. You can change the values in theblue cells as many times as you like.F. Step Six: When you have your final output, SAVE yourfile by choosing the "SAVE AS" option under the "FILE"menu in Excel . Make sure that you use a different filename to the original master copy. (this will safeguardagainst deletion of the master copy)G. Step Seven: Your work is now ready to PRINT. You mayfind that Excel does not have enough memory to displaythe spreadsheet fully. The print range has been setup forA4 landscape paper and will print only the first 2-3 pages ofthe spreadsheet (the rest of the spreadsheet consists ofintermediate calculations). If you find that the spreadsheetwill not fit on the paper, choose "PAGE SETUP" from the"FILE" menu in Excel and reduce the size of the sheet.Page 2 of 3SEPARATOR SIZING SPREADSHEET - INSTRUCTION NOTESAnother option available is to choose A3 sized paper(page setup menu) to print out your spreadsheet. It isnot recommended that the print area be altered as thishas been preset. However, if the print area needs to bealtered, please use the following procedure."TOOLS""OPTIONS""GENERAL""MICROSOFT EXCEL 4 MENUS""OK"(HIGHLIGHT THE AREA THAT YOU WISH TO PRINT)"OPTIONS""SET PRINT AREA"IV. ADDITIONAL NOTESA. THE CALCULATION TITLE BLOCKThere is a title block at the bottom of each pageof the spreadsheet.Spaces have beenprovided for entering the calculation title, projectnumber and calculation number. These spaces are accessedby moving the mouse pointer into the particular box andclicking once with the left hand mouse button. At thispoint, an object box will appear. Simply click insidethe box once using the left hand mouse button and enterthe data in the normal way. When you have finishedtyping the information, move the mouse pointer to anotherpart of the spreadsheet and click once with the left handmouse button.NOTE: While space has been provided on the title blockfor entering the originators and checkers initials andrelevant dates, these spaces cannot be accessed by theuser. This is because signatures are required to behand written by the originator and checker.B. MAIN MENUThe main menu on the separator sizing spreadsheetallows the user to access any of the sheets in theworkbook through the use of a macro button. Once thedesigner is in a particular worksheet, they can return tothe menu by clicking the "MENU" macro button inthe individual worksheet.Page 3 of 3
