See Appendix H: Reciprocal Calculation Method for Certain Refined Hydrocarbon Solvent Vapor Mixtures. 56 0 obj <> endobj Hydrotreated heavy naphtha (petroleum) is a complex mixture of hydrocarbons ob-tained by treating a mineral oil fraction with hydrogen in the presence of a catalyst. The air pump that was used to force naphtha vapor to the engine for starting can also be utilized to provide air pressure for the ship's whistle. In about two minutes the pressure gauge would indicate 10 to 15 pounds and the operator would open the injector valve (C). Mixtures labelled naphtha have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar and peat. 9.19 Reid Vapor Pressure: 0.13 psia NOTES JUNE 1999. Notes: As Rubber solvent (Naphtha) [no CAS]. 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. Now, you probably want the True Vapor Pressure (TVV) at temperature T. Knowing the Reid Vapor Pressure (RVP measured at 37.8C and given in gage pressure), the ASTM distillation curve, T and . Naphtha weighs 0.74 gram per cubic centimeter or 740 kilogram per cubic meter, i.e. Solution: Here, we need to find the vapor pressure of urea corresponding to the water vapor pressure.

So it typically only makes up a very small portion of the gasoline pool. 0000031525 00000 n I assume the term wild comes from the high vapor pressure and the fact that there generally are not many specs on it, since it is basically a small leftover stream that . Answer (1 of 4): In many countries, naphtha refers to diesel fuel or even gasoline. Low-boiling naphtha (sometimes referred to as light naphtha) is another hydrocarbon product that is also somewhat interchangeable with natural gasoline and lease condensates, and is the product designated as naphtha, specifically low-boiling naphtha.
