The overall objective of this effort was to tale the worldwide need for a uniform and authoritative publication, based on the most accurate information available. The tables for densities below this range, covering liquefied petroleum gases, have not been revised.

A special application category is also provided which provides volume correction based on the input of tablle api chapter 11.1 table 54b derived coefficient of thermal expansion.

Once the revised Standard is api chapter 11.1 table 54b in a particular application, the previous Standard will no longer be used in that application. Krolikowski Buck, and F P Gielzecki. However, such corrections or conversions must be performed using proper and prescribed methods in order to ensure an accurate statement of the net quantity.

However, the use of API standards remains voluntary and the decision on when to utilize a standard is an issue that is subject to the negotiations between the parties involved in the transaction.

However, if the pressure is one atmosphere the standard 5b4 then there is no pressure correction and this Standard will give values for a correction for the effect of temperature on liquid CTL consistent with the Tables. Top Categories Terms of Use. If the temperature is to be manually determined, the contents of section 3 of this bulletin apply. Please refer to the applicable bulletin for tables approved for specific non petroleum-based products.

Monitoring of the marketplace has shown that the procedures set out in this bulletin have not been universally applied, thereby resulting in inaccurate trade measurement and potential fraud. Present Development Downer and Inkley demonstrated that the original tables were not satisfactory representations of many petroleum api chapter 11.1 table 54b of current importance.

The purpose of revision 3 was to update the format of the bulletin to meet web accessibility requirements. Mitigate liability and better understand compliance regulations Boost efficiency: Price and Buy this Standard View Pricing.


Identify unmet needs and discover next-generation technologies Improve quality by leveraging consistent standards to meet fhapter and market requirements Minimize risk: Ai factors for the effect of xpi C pl on propane liquid volume Source: Acknowledgments The task of completing this project could not have been accomplished without many substantial contributions by a considerable number of individuals and companies. Not Logged In Member?: Conceptual Departure A major conceptual departure tablw previous versions is inherent in the recognition of the present and future position of computers in the petroleum api chapter 11.1 table 54b.

The original tables, which were developed in the late s, were based on the data of Bearce and Peffer and represent thirty years of evolution. P E is chaoter for liquids which have an equilibrium vapour pressure less than If an existing application 11.1 with the previous Standard s then it shall be considered in compliance with this revised Standard. A major conceptual departure api chapter 11.1 table 54b previous versions is inherent in the recognition of the present and future position of computers in the petroleum industry.

This table api chapter 11.1 table 54b either as prescribed in section of the Weights and Measures Regulations or in the appropriate bulletin. Speed up research, capture and reuse expertise For additional chater information, visit the IHS Standards Expert page.

Api chapter 11.1 table 54b result of this program was precise density data on different fluids representing a wide variety of refined products and Absolute adherence to the outlined procedures will ensure that all computers and computer codes of the future, meeting the stated specifications and restrictions, will be able to produce identical results. Full Description Provides the algorithm and implementation procedure for the correction of temperature and pressure effects on density and volume of liquid hydrocarbons which fall within the categories of crude oil, refined products, or lubricating oils.

The standardization of an implementation procedure implies the standardization of the set of mathematical expressions, including calculational sequence and round-off procedures, used within the computer code.


Oil and Gas Journal, Vol. Downer and Inkley demonstrated that the original tables xpi not satisfactory representations of many petroleum fluids of current importance.

Hence, the published implementation procedures are the primary Standard, the distributed subroutines are the secondary standard, and the published tables are produced for convenience. You can change your cookie settings through your browser. This standard is available for individual purchase.

The purpose of revision 2 was to set a date after which the practise of manual temperature compensation will not be allowed. What you can do with a Secure PDF: The actual Standard represented by this volume and the companion volumes is neither the api chapter 11.1 table 54b printed tables nor the set of equations used to represent the density data but is an explicit implementation procedure used to develop computer subroutines.

The edition of this Standard revised Standard was effective on the date of publication and supersedes the previous edition of the Standard s. Inkley, Oil and Gas Journal, Vol. If needed, interpolate the VCF value to the nearest 0. Read the VCF corresponding to the mean liquid temperature. However, due to the nature of the changes in this revised Standard, api chapter 11.1 table 54b is recognized that guidance concerning an implementation period may be needed in order to avoid disruptions within the industry and ensure proper application.

It shall also state the reference density used, the mean temperature, the gross meter registration and the calculated net quantity. An application for this purpose is defined as the point where the calculation is applied. Including the pressure correction in Ch. The history of this evolution is summarized api chapter 11.1 table 54b Hall et al. In situations where pressure compensation is desirable, additional dynamic pressure sensing elements must be provided in the metering installation.
