CHAPTER 12 - CALCULATION OF PETROLEUM QUANTITIES SECTION 4 - BASE PROVER VOLUME DETERMINATION PART 1 - WATERDRAW VOLUMETRIC METHOD

1. Scope

1.1. General

The purpose of standardizing calculations is to produce the same unbiased answer, from the same measurement data, regardless of whom or what does the computing.

This document provides a standardized calculation method and procedure for the determination of a base prover volume using the waterdraw volumetric method under defined conditions, regardless of the point of origin, destination, or units of measure, required by governmental organizations. The criterion contained in this document allows different users on different computing devices, to arrive at identical results using the same standardized input data.

This document rigorously specifies the equations, rules for rounding, the sequence of the calculations, and the discrimination levels of all numbers to be used in these calculations. No deviations from this document are permitted since the intent is to serve as a rigorous standard.

2. Application

2.1.1. Methods

The Base Prover Volume (BPV) of a prover (displacement or open tank) may be determined by one of three methods - waterdraw, master meter or gravimetric.

The operational procedures and acceptance criteria employed to calibrate a prover by the waterdraw method are specified in API MPMS Chapter 4.9.2 - Determination of the Volume of Displacement and Tank Provers by the Waterdraw Method of Calibration.

2.1.2. Applicable Liquids

The application of this standard shall be limited to potable water, which is assumed to be clean, air/gas free, and to properly implement the procedures to correct measured volumes at flowing temperatures and pressures to corresponding volumes at base (reference or standard) conditions. To accomplish this, the density correlations for water specified in API MPMS Chapter 11.4.1 - Water Density are

contained in this document.

2.1.3. Base Conditions

Historically, the measurement of some liquids for custody transfer and process control, have been stated in volume units at base (reference or standard) conditions.

The base conditions for the measurement of liquids, such as crude petroleum and its liquid products, having a vapor pressure equal to or less than atmospheric pressure at the base temperature are -

International System (SI) Units Pressure - 101.325 kPa (14.696 psia) Temperature - 15.00 ºC (59.0 ºF)

United States Customary (USC) Units

Pressure - 14.696 psia (101.325 kPa) Temperature - 60.0 ºF (15.556 ºC)

Base conditions may change based on contract and from one country to the next. Therefore, it is necessary that the base conditions be identified and specified in all standardized volumetric flow measurements by all the parties involved in the measurement.

4.2. base conditions

Reference pressure and temperature conditions, as defined by standard, regulation, or contract, used in custody transfer measurement calculations of fluid volumes and other calculations.

4.3. base prover volume (BPV)

The volume of the prover at base conditions as shown on the calibration certificate.

4.4. calibrated prover volume (CPV)

The volume of the prover at base conditions as determined from a calibration pass or run(s) by the waterdraw method or from one prover calibration run set by the master meter method.

4.5. calibration certificate

A report documenting the calibration of a measurement device such as a meter prover, a thermometer or pressure gauge and its traceability to a national metrological institute (e.g., National Institute of Standards and Technology).

4.6. certified temperature or pressure device

A temperature or pressure measurement device documented to have been calibrated over the operating range against an appropriate standard traceable to primary standards maintained by an internationally recognized standards organization such as the National Institute of Standards and Technology.

4.7. correction for temperature of steel (CTS)

Correction for changes in length, area or volume of a steel prover, tank, tank car or other vessel, due to changes in the steel temperature between its reference temperature and its operating temperature.

4.8. correction for pressure on steel (CPS)

Correction for changes in volume of a steel prover, tank, tank car or other vessel, due to changes in the internal pressure between its reference pressure and its operating pressure.

4.9. correction for pressure on liquid (CPL)

Correction for changes in the density of a liquid, due to the difference between its reference pressure and its operating pressure.

4.10. field standard test measure

A volumetric, non-pressurized, cylindrical, metal container, with a cylindrical neck containing a gauge glass and scale. Designed to stringent specifications, it “contains” or “delivers” an exact volume between a fixed bottom or a bottom shut-off valve and an upper neck scale reading."Flowrate (Qav)

Property of a measurement result whereby the result can be traced back to NIST by an unbroken chain of calibrations.

4.14. pass

A single movement of the displacer, in a displacement prover, that activates the start-stop detectors.

4.15. primary standard

A measurement standard whose value is determined by NIST or appropriate National Metrological Institute.

4.16. prover calibration certificate

A document package stating the Base Prover Volume (BPV) which includes the run data used to calculate the BPV, and the traceability documentation.

4.17. prover with integral detectors

Free displacer prover designs, both unidirectional and bidirectional applications, employ a sphere or piston displacer in a circular conduit or pipe. The detectors are integral to the pipe. In other words, the detectors are mounted directly to the pipe through which the free displacer passes.

4.18. prover with external detectors

Captive displacer prover designs employ a piston attached to a shaft. The displacement of the shaft is constant except that it moves into and out of the calibrated section during a calibration run. Usually, there is one or two externally mounted detectors and/or guide rods attached to the captive piston displacer. Since provers have externally mounted detectors, the thermal effect on the steel may not be the same for the area aspect as for the linear aspect. In terms of a prover calibration, as well as a flowmeter calibration, it is necessary to obtain both a prover barrel temperature and a detector shaft temperature.

4.19. reference conditions

The base conditions of temperature and pressure (e.g., 60.0 °F and 0 psig, 60.0 °F and equilibrium vapor pressure, 15.00 °C and 101.325 kPa, or 15.00 °C and equilibrium vapor pressure) to which measured volumes are to be corrected.

4.20. reference pressure (Pb)

The base conditions of pressure (e.g., 0 psig, 14.696 psia, 101.325 kPaa, and equilibrium vapor pressure) to which measured volumes are to be corrected.

4.21. reference temperature (Tb)

The base conditions of temperature (e.g., 60.0 °F, 15.00 °C, 20.00 °C) to which measured volumes are to be corrected.

4.22. roundtrip or calibration run

The combination of a single pass of the displacer in one direction (e.g., out) followed by a single pass of the displacer in the opposite direction (e.g., back) in a bi-directional displacement prover.

4.23. run

One pass of the displacer between detectors on a unidirectional prover; one round trip of the displacer between detectors on a bi-directional prover; one filling or emptying of an atmospheric tank prover

reference conditions. The calibration requirements are a function of the prover classification.

There are two general classes of provers that employ the waterdraw calibration method - displacement provers and open tank provers.

Sub-classes of displacement provers are unidirectional and bidirectional flow designs, as well as free and captive displacers (sphere or piston)

Sub-classes of open tank provers are top filling or bottom filling designs.

6.2. Displacement Provers - Unidirectional Design

For unidirectional provers, a calibration shall meet the following criteria:

Flowrate stability within a calibration run (or ‘Out’ pass) Calibration shall be considered acceptable when prover volumes at reference conditions

of three (3) or more consecutive calibration runs shall exhibit a range of 0.020 % or less. Flowrate between consecutive calibration runs shall change by at least 25 % or more.

Under special operational circumstances, and with the agreement of all parties concerned in the calibration, the flow rate change between consecutive roundtrips (or calibration runs) may be waived.

Displacement Provers - Bidirectional Design

For bidirectional provers, a calibration shall meet the following criteria:

Flowrate stability within a roundtrip (consecutive ‘Out’ and ‘Back’ passes) Calibrated Prover Volumes (CPV) for the "Out" pass of three (3) or more consecutive

roundtrips shall exhibit a range of 0.020 percent or less. Calibrated Prover Volumes (CPV) for the "Back" pass of three (3) or more consecutive

roundtrips shall exhibit a range of 0.020 percent or less. Calibrated Prover Volumes (CPV) of three or more consecutive roundtrips shall exhibit a

range of 0.020 percent or less. Flowrate between the “Out” and the “Back” pass shall remain the same for each

roundtrip. Flowrate between consecutive roundtrips shall be changed by at least twenty five

percent (25%) or more.

Under special operational circumstances, and with the agreement of all parties concerned, the flow rate change between consecutive calibration roundtrips may be waived.

Open Tank Provers

Copyright API. All rights reserved.

16

For open tank provers, the calibration shall be considered acceptable when the following criteria are satisfied:

Flowrate stability within a calibration run (or ‘Out’ pass) Calibrated Prover Volumes (CPV) for two (2) or more consecutive calibration runs

shall exhibit a range of 0.020 percent or less. After adjusting the scale(s) and resealing, a third calibrated volume at reference

conditions shall be determined. This volume (BPVver) shall be within ±0.010 % from New Base Prover Volume (BPVnew).

There is no flow rate variation criterion between consecutive calibration runs for open tank provers.

Range (‘Out’ R%, ‘Back’ R%, ‘Trip’ R %, and ‘Qav’ R %)

As a measure of repeatability and reproducibility, the following equation shall be utilized to verify the range of results for displacement provers and open tank provers.

R(%) = ( Maximum – Minimum ) / ( Minimum ) x 100

The Range - ‘Out’ R%, ‘Back’ R%, ‘Trip’ R %, and ‘Qav’ R % - shall be determined for CPVout, CPVback, CPVtrip and Qav for three or more consecutive calibration runs.

Displacement Prover Wear – ΔBPV, ΔBPV%

Although not a requirement, the user community traditionally determines the ΔBPV and ΔBPV% to ascertain the physical condition of a displacement prover.

ΔBPV = BPVnew – BPVold

And,

ΔBPV% = ΔBPV / BPVnew x 100

Where, ΔBPV Difference Between BPVold and BPVnew for Displacement Prover BPVnew New Base Prover Volume BPVold Previous (or Old) Base Prover Volume ΔBPV% Percent Difference Between BPVold and BPVnew for Displacement Prover

If the prover was disassembled, modified, re-coated, detector switch adjusted, detector switch replaced, then the BPVold is not representative of the current prover (artefact). For this scenario, the ΔBPV and ΔBPV% are both set to zero.

Verification Tolerance for Open Tank Prover - ΔV, ΔV%

As a measure of reproducibility and to ensure the reading scales have been set properly, the following equation shall be used to verify the BPV results for an open tank prover -

ΔV = BPVnew - BPVver

And,

ΔV% = ( ΔV / BPVnew ) x 100

Where, ΔV Difference Between BPVnew and BPVver for Open Tank Prover BPVnew New Base Prover Volume BPVold Previous (or Old) Base Prover Volume ΔV% Percent Difference Between BPVnew and BPVver for Open Tank Prover

7. Correction Factors

In the waterdraw method, the field standard test measure(s) and prover being calibrated are subject to correction factors to determine the Calibrated Prover Volume (CPV) and Base Prover Volume (BPV).

Corrections are made for -

water density in test measure(s), RHOWtm and CPLtm effect of thermal expansion of steel in test measure(s), CTStm elastic distortion of test measure due to pressure, CPStm water density in prover, RHOWp and CPLp effect of thermal expansion of steel prover, CTSp elastic distortion of prover due to pressure, CPSp

Water Density (RHOWt)

The Patterson and Morris (PM) water density correlation predicts the density of water (RHOWt) at standard pressure (101.325 kPaa, 14.696 psia) as a function of temperature in degrees Celsius and shall be calculated using the following equation -

RHOWt = RHOo x { 1 – [ ( A x ΔT ) + (B x ΔT2 ) + (C x ΔT3 ) + ( D x ΔT4 ) + ( E x ΔT5 ) ] } Where,

RHOWt density at temperature T and Pb in kg/m3

RHOo density at temperature To, 999.973 58 kg/m3 T temperature, in °C To 3.9818 °C ΔT temperature difference, in °C

B 7.926 504 × 10-6

C –7.575 677 × 10-8

D 7.314 894 × 10-10

E –3.596 458 × 10-12

And,

ΔT = T – To

N.B.: When T is measured in °F units, it has to be converted to °C units for the PM water density correlation. To maintain the predictive precision of the PM water density correlation, the conversion of T from XXX.xx °F to XX.xxx °C is required.

To convert from °F to °C,

T in °C = (°F – 32) x 5 / 9

The water density correlation is applicable from 1.00 to 40.00 °C (33.8 to 104.0 °F) and produces the following results -

Density at 15.00 °C (59.0 °F) 999.102 kg/m3

Density at 20.00 °C (68.0 °F) 998.206 kg/m3

And,

ΔTtm = Ttm – To

N.B.: When Ttm is measured in °F units, it has to be rounded then converted to °C units for the PM water density correlation. To maintain the predictive precision of the PM water density correlation, Rounded Ttm shall be converted from XXX.xx °F to XX.xxx °C.

Water Density in Prover at Pb (RHOWp)

The water density for a test measure at Pb (RHOWp) shall be calculated using the PM equation as follows for each ‘pass’ -

RHOWp = RHOo x { 1 – [ ( A x ΔTp ) + (B x ΔTp2 ) + (C x ΔTp3 ) + ( D x ΔTp4 ) + ( E x ΔTp5 ) ] } Where,

RHOWp prover density in kg/m3 at Pb

Correction for Temperature on Steel Container (CTS)

Any container (displacement prover, tank prover, or field standard test measure), when subjected to a change in temperature will change its volume accordingly. The volume change, regardless of shape, is proportional to the coefficient of thermal expansion of the single construction material(s).

The linear coefficient of thermal expansion (GLp) is required for displacement provers.

The linear or cubical coefficient of thermal expansion (GLp, GCp) may be used for an open tank prover.

The linear or cubical coefficient of thermal expansion (GLtm, GCtm), depicted on the Report of Calibration furnished by the calibrating agency (e.g., NIST, NEL), shall be used for field standard test measure(s).

Correction for Temperature on Test Measure (CTStm)

The CTS for a test measure (CTStm) shall be calculated as follows for each test measure fill -

CTStm = { 1 + [ GLtm x (Ttm - Tb) ] }^3 Where,

CTStm Correction for Temperature on Steel Test Measure GLtm Coefficient of linear thermal expansion of Test Measure Tb Base temperature Ttm Mean liquid temperature in Test Measure

N.B.: When Tb and Ttm are in XXX.xx °F units, then GLtm has tobe in per °F units. When Tb and Ttm are in XX.xxx °C units, then GLtm has to be in per °C units.

9. Precision, Rounding, Discrimination and Reporting Levels

Precision

The minimum precision of the computing hardware has to be equal to or greater than a ten-digit calculator to obtain the same answer in all calculations.

Rounding

When a number is to be rounded to a specific number of decimals, it shall always be rounded off in one step to the number of figures that are to be recorded and shall not be rounded in two or more steps of successive rounding. The rounding procedure shall be in accordance with the following:

When the figure to the right of last place to be retained is 5 or greater, the figure in the last place to be retained should be increased by 1.

If the figure to the right of the last place to be retained is less than 5, the figure in the last place retained should be unchanged.

Discrimination and Reporting Levels

The objective of this standard is to record the readings, then perform the calculations.

Chapter 4.9.1 requires a minimum accuracy of ± 0.10 ºF (± 0.05 ºC) and +/- 1 psig (± 0.069 bar, ±6.895 kPa) for the temperature and pressure devices involved in the determination of the BPV.

This standard requires the user to record to the levels shown in the Tables 2 and 3 (temperature, pressure) to achieve the 1 ppm agreement, but not beyond these levels.

34

If the user records the observed temperature values to the nearest 0.10 ºF, then these would be converted to the nearest 0.056 ºC. If the user records the observed pressure values to the nearest 1.0 psig, then these would be converted to the nearest 0.069 bar or 6.895 kPa. 

Technically, it is not achievable for temperature to be accurate to less than ± 0.10 ºF (± 0.05 ºC). This limitation is due to thermowell heat transfer, transfer medium, temperature lagging, temperature device limitations (design, sensor type, certification limitations), ambient effects, and so forth.

For field temperature measurements the maximum discrimination levels using digital or analog field sensing devices, shall be XX.xxx ºC or XXX.xx ºF.

N.B.: When Tp and Ttm are measured in °F units, these parameters have to be converted to °C units for both the PM water density (RHOWp, RHOWtm) and Tanaka compressibility factor (Fp) correlations. To maintain the predictive precision of these correlations, the calculation procedure requires conversion of the Rounded Tp from °F to °C units to XX.xxx °C.

For pressure field measurements the maximum discrimination levels using digital or analog field sensing devices, shall be XX XXX.0 kPa or XXX.xx bar or X XXX.0 psi.

All required data and equation results shall be recorded and rounded (reporting) in accordance with the discrimination and reporting levels specified in the section. For detailed guidance, the user should reference the Process Maps and Examples contained in this standard.

Discrimination and reporting levels different than those specified are not permitted for determining Base Prover Volume.

10. Typical Steel Properties

The prover owner should obtain the steel properties (GCp, GLp, GLd, E) from the original manufacturer. However, it is common practice to employ the prover steel properties contained in the following tables for field application.

Note: The cubical coefficient of expansion (GC) is equal to the three times the linear coefficient of expansion (GL). The GC and GL values listed in Table 13 are valid over a range of 0 to 100 °C (32 to 212 °F).

The following Typical Steel Properties Tables are presented for informational purposes –
