17、leum Measurement Standards (MPMS) Chapter 19.4 was published followinga revision that was carried out concurrently with revisions to Chapter 19.1, published as the fourth edition, andChapter 19.2, published as the third edition. Primary changes are:1) Consolidation of common material in Chapter 19.4

18、. Material that had previously been included in both Chapters19.1 and 19.2 has been moved to Chapter 19.4. Chapter 19.4, which was previously Recommended Practice forSpeciation of Evaporative Losses, now has the title Evaporative Loss Reference Information and SpeciationMethodology. This Chapter had

19、 already contained reference information on the properties of chemicals andtypical petroleum liquids, and this information has now been removed from Chapters 19.1 and 19.2. In addition,meteorological data have been moved from Chapters 19.1 and 19.2 to Chapter 19.4. In the revised documents:a) Meteor

20、ological data are found in Chapter 19.4,b) Calculation of storage tank temperatures is found in Chapters 19.1 and 19.2 (in that fixed-roof tanks involvecalculation of the vapor space temperature in order to determine vapor density, whereas this step is notinvolved in estimating emissions from floati

21、ng-roof tanks), andc) Calculation of true vapor pressure is found in Chapter 19.4 (in that this is now calculated in the same mannerfor both fixed- and floating-roof tanks).2) Reconciliation of nomenclature. Chapters 19.1 and 19.2 previously had different nomenclature for the samevariables. These re

22、visions adopt a common set of symbols for both chapters.3) Reorganization of the formats. In addition to common material having been removed from Chapters 19.1 and 19.2,the remaining text has been edited to remove unnecessarily verbose or repetitive language. The summary tableswere deemed redundant,

23、 and have been deleted.4) Appendices. Appendices have been redesignated as annexes. 5) SI units. An annex has been added to each chapter to address SI units.Chapter 19.4, third editionIn addition to common reference material being moved to Chapter 19.4, the following changes have been made:1) Solar

24、absorptance factors. The former designations of Good and Poor have been replaced with the designationsNew and Aged, and a new category designated Average has been introduced.2) Alternative methodology for calculating storage tank temperatures. An API study of storage tank temperaturesconcluded that

25、a more sophisticated model for estimating storage tank temperatures has relatively little impact onestimated emissions, and thus the methodology now presented in Chapters 19.1 and 19.2 is the same aspreviously appeared in Chapter 19.1 (and in EPA AP-42). However, a more sophisticated model has been

26、addedas Annex I in Chapter 19.4. 3) No. 6 Fuel Oil. The default properties for No. 6 Fuel Oil have been revised, resulting in a significant increase in theestimated true vapor pressure. The former default properties are now presented as being suitable for vacuumresidual oil. A new default speciation

27、 profile has also been added for No. 6 Fuel Oil. The study on which thesechanges are based has been added as Annex G.v4) Maxwell-Bonnell correlations. The annex presenting the Maxwell-Bonnell correlations has been edited with theconclusion that the separate correlations for predicting the normal boi

28、ling point from distillation data are notreliable.5) Determination of true vapor pressure. Cautions have been added to section 4.2 of Chapter 19.4 with respect tothe use of Reid vapor pressure to determine the stock true vapor pressure, and ASTM test methods D2879 andD6377 have been referenced for d
