API MPMS 19.3 PART F Document Information:
Title
Manual of Petroleum Measurement Standards Chapter 19.3 - Evaporative Loss Measurement Part F - Evaporative Loss Factor for Storage Tanks Certification Program
American Petroleum Institute
Publication Date:
Mar 1, 1997
Scope:
BACKGROUND
The purpose of this standard is to provide a mechanism for users
of the API evaporative loss standards, and related documents, to
verify the accuracy of device specific loss factors that they are
requested to use. The certified loss factors developed under this
standard denotes that an API certified facility certifies that the
factors published for certain specific devices have been developed
in a way that is consistent with that used for the generic or
default factors published in the API standards. Use of the
certified factors is believed to improve the accuracy of the
calculated evaporative loss. The generic factors are not being
withdrawn and are still published by API; this is an extension of
the standards to incorporate new and more specific information.
API does not make any recommendation, conclusion, or warranty
concerning a device having a certified loss factor. Likewise, the
user should not draw any inference concerning the differences
between devices that have certified factors and those that do not.
Participation in the certified loss factor program is strictly
voluntary.
API publishes certain standard methods for estimating the
evaporative losses from storage tanks. These methods, namely MPMS
19.1 and 19.2, require inputs for various parameters that affect
the quantity of material evaporated. Some of these inputs are loss
factors that are specific to the type of equipment being
considered. API has traditionally supplied default factors for
these values that were developed from API's own testing programs.
These factors are not meant to represent all equipment types or to
specifically represent a particular device. They are referred to as
generic loss factors. Specific devices may have loss factors that
are different from those listed in 19.1 or 19.2. Users of the API
calculation methods may have a need to reflect the capabilities of
a specific device in their evaporative loss calculations.
The document covers the methods and procedures that shall be
used to petition API to certify a device-specific evaporative loss
factor for use in place of those default factors listed in MPMS
19.1, and 19.2. These factors may also be applicable for use with
other calculation techniques that are comparable to or derived from
the above API documents. The process of applying to API for a
device specific loss factor and receiving a certified factor for
API is referred to here as the certification process.
This standard describes the specific test protocols required to
be performed, the certification requirements for the testing
facility, the manner in which the data must be submitted, and the
reviews and procedures that API will use to review the submitted
data. Options available to API to publish the results of its review
are addressed in this document but not defined.
LIMITATIONS
The certification of a loss factor for a device does not in any
way imply that the device is acceptable, effective, or safe for any
proposed service. It does not imply recommendation of the device by
API or enhanced quality or features as compared to other similar
devices.
Evaporative loss control devices are not primarily chosen based
on their loss rate, but on a variety of other factors.
Certification of a loss factor for a device does not imply that the
device is of higher quality or in any way better than any other
device, with or without a certified loss factor.
The use of a certified factor does not remove or mitigate the
limitations or restrictions on the API evaporative loss standards.
The certified factors are to be used as substitutes for factors in
API or related documents.
