PART 219 ORGANIC MATERIAL EMISSION STANDARDS AND LIMITATIONS FOR THE METRO EAST AREA
SECTION 219.110 VAPOR PRESSURE OF ORGANIC MATERIAL OR SOLVENT
Section 219.110 Vapor Pressure of Organic Material or Solvent
a) If the organic material or solvent consists of only a single compound, the vapor pressure shall be determined by ASTM Method D2879-86 (incorporated by reference in Section 219.112 of this Part) or the vapor pressure may be obtained from a publication such as: Boublik, T., V. Fried and E. Hala, "The Vapor Pressure of Pure Substances," Elsevier Scientific Publishing Co., New York (1973); Perry's Chemical Engineer's Handbook, McGraw-Hill Book Company (1984); CRC Handbook of Chemistry and Physics, Chemical Rubber Publishing Company (1986-87); and Lange's Handbook of Chemistry, John A. Dean, editor, McGraw-Hill Book Company (1985).
b) If the organic material or solvent is in a mixture made up of both organic material compounds and compounds which are not organic material, the vapor pressure shall be determined by the following equation:
|
Pom |
= |
n ∑ i=1 |
Pi |
Xi |
|
n ∑ i=1 |
Xi |
|||
where:
|
Pom |
= |
Total vapor pressure of the portion of the mixture which is composed of organic material; |
|
|
|
|
|
n |
= |
Number of organic material components in the mixture; |
|
|
|
|
|
i |
= |
Subscript denoting an individual component; |
|
|
|
|
|
Pi |
= |
Vapor pressure of an organic material component determined in accordance with subsection (a) of this Section; |
|
|
|
|
|
Xi |
= |
Mole fraction of the organic material component of the total organic mixture. |
c) If the organic material or solvent is in a mixture made up only organic material compounds, the vapor pressure shall be determined by ASTM Method D2879-86 (incorporated by reference in Section 219.112 of this Part) or by the above equation.
