The vapor pressure for water at 60F is 0.5 psia. %PDF-1.5 % %%EOF Naphta is characterized as light or heavy depending upon its distillation cut, and is used as a feedstock of high-octane gasoline. based on any of the following: PDF documents can be viewed with the free Adobe Reader, Signs/symptoms from exposure to the substance, Substance categories (flammable, meth lab, etc. Naphtha is a term used to describe a class of hydrocarbon mixtures obtained from the distillation of Petroleum or Coal-Tar. Question: If the vapor pressure of naphtha is 40 mmHg, a) what is its saturation air level in ppm? Benzene, C6H6, is a clear colorless to light-yellow liquid, flammable with a petroleum-like, aromatic odor. The boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric pressure.For water, the vapor pressure reaches the standard sea level atmospheric pressure of 760 mmHg at 100C. It is defined as the absolute vapor pressure exerted by the vapor of the liquid and any dissolved gases/moisture at 37.8 C (100 F) as determined by the test method ASTM-D-323, which was first developed in 1930 [2] and has been revised several times (the latest version is ASTM D323-15a). Naphtha weighs 0.74 gram per cubic centimeter or 740 kilogram per cubic meter, i.e. p a (kPa a) = p r (kPag) + p atm (kPa a), patm = 100 kPa a at sea level. Naphtha was the name originally applied to the more volatile kinds of petroleum issuing from the ground in the Baku district of Azerbaijan and Iran. This applies to both experimentally derived and estimated vapor pressure data. [.adYE#YdJ\mI(;k,x"8U@`/P0QR!D%HP.!|Lqt:%44, &A8@RPA(-PP@Z Naphtha is usually limited on RVP but you want as much C4 in Naphtha as gasoline is more valuable than LPG. For comparison, the vapor pressure of water at 25C and 1 atm is 23.8 mm-Hg, while its vapor pressure is 760 mm-Hg (1 atm) at 100C, its boiling point. I am looking for vapor pressure data for a Naphtha fraction sold as a plastic extrusion aid. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website.

At 100 oF (38 oC) vapor pressure of 13.8 psia can be found in the boundary between gasolines (sg~0.71-0.77, per wikipedia) and natural gasolines (typical sg=0.67, per wikipedia). - Biobased naphtha comes from the refining of biobased feedstocks. Class IB Flammable Liquid: Fl.P. 0000011573 00000 n b) what is its saturation air level in %? Open drum carefully as content may be under pressure. Dispose of rinse water in accordance with local and national regulations. The velocity head or term vs2/2g is often quite small, of the order of 1 foot or less and this is no exception so we will therefore neglect it. This is a mixture of C9-C13 naphthenes, iso- and n-paraffins. Naphtha splitters were revamped so that the majority of benzene and benzene precursors (cyclohexane and methylcyclopentane) ended up in the light naphtha fraction instead of the heavy naphtha fraction. NAPHTHA 1. Notes: As Rubber solvent (Naphtha) [no CAS]. Since this is at equilibrium, liquid is evaporating into gas, and gas is condensing into liquid. vapour pressure, pressure exerted by a vapour when the vapour is in equilibrium with the liquid or solid form, or both, of the same substancei.e., when conditions are such that the substance can exist in both or in all three phases. The average error from the proposed correlation is about 0.06 bar (0.88 psia). 399.47 - 491.79: 3.97067: 1606.529-85.923: Camin and Rossini, 1955 : Benzene - Thermophysical properties.
