True vapor pressure definition

True vapor pressure means the equilibrium partial pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute (API) Bulletin 2517, Evaporation Loss from External Floating Roof Tanks, 1980. The API procedure may not be applicable to some high viscosity or high pour crudes. Available estimates of true vapor pressure may be used in special cases such as these.

True vapor pressure means the equilibrium partial pressure exerted by petroleum liquid as determined in accordance with methods described in American Petroleum Institute Bulletin 2517, Evaporation Loss from Floating Roof Tanks, 1962.

True vapor pressure means the equilibrium partial pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute Bulletin 2517, Evaporation Loss from External Floating-Roof Tanks, Second Edition, February 1980 (incorporated by reference—see §60.17).

Examples of True vapor pressure in a sentence

• True vapor pressure means the pressure exerted when a solid or liquid is in equilibrium with its own vapor.

• True vapor pressure (TVP) is the criterion that the Tanks 4 software, developed by EPA and API, uses to determine tank content emissions characteristics.

• If such audit shall disclose that Tenant has understated the Gross Sales for such Lease Year by more than three (3%) and Landlord is entitled to any additional Annual Percentage Rent’ Tenant shall pay to Landlord all of Landlord’s reasonable cost of such audit.

• The equation is as follows (from AP-42, Section 5.2 [June, 2008]): LL = 12.46 * SPM/(TR)Where: LL = Loading losses (lb/Mgal loaded)S = saturation factor (AP-42, Table 5.2-1) P = True vapor pressure of liquid (psia)M = molecular weight of vapors (lb/lbmole) TR = temperature of liquid loaded (°R) Compliance with the monthly VOC emission limitation is demonstrated through the recordkeeping established in d)(1), the results of the annual gas analysis and the methodology established above.

• WVOC = 0.166677 lb/ft3 * Vinst * [TVP / (12.9-TVP)] Where: WVOC = Mass of hydrocarbon emissions in lb/day Vinst = Air volume flowrate in standard cubic feet per day TVP = True vapor pressure of hydrocarbons in lb/in2 absolute K.
