Vapor pressure gasoline

These data, given for illustrative purposes, show that even for the coming years the refiner will be pressed to reduce the gasoline vapor pressure as much as possible. 

Gasoline Vapor Pressure/Light Olefin Yield... 

Reid Vapor Pressure (RVP) is gasoline vapor pressure at I00°F. 

The vapor pressure of petroleum or a petroleum product is the force exerted on the walls of a closed container by the vaporized portion of a liquid. Conversely, it is the force that must be applied to the liquid to prevent it vaporizing further. The vapor pressure increases with increase in temperature and is variously expressed in terms of millimeters of mercury, pounds per square inch, or other equivalent units of pressure depending on common usage. Gasoline vapor pressure depends critically on its butane content, and in the refinery the final adjustment of vapor pressure of a gasoline to meet the specification is often made by butane injection. 

Our automotive pressure sensor line offers a wide range of choices. At one end of the range is the gasoline vapor pressure sensor for 5 kPa used to detect leaks from the gasoline pipe. At the other end is the common-rail pressure sensor for...

Normal butane for gasoline-vapor pressure control... 

The analyst now has available the complete details of the chemical composition of a gasoline all components are identified and quantified. From these analyses, the sample s physical properties can be calculated by using linear or non-linear models density, vapor pressure, calorific value, octane numbers, carbon and hydrogen content.

Vapor pressure specifications for gasolines in Europe (Distribution by class). 

Among several other gasoline volatility criteria, we will cite the V/L ratio and the relations existing between the various ways of expressing the vapor pressure. 

Outside of their very high resistance to auto-ignition, the aviation gasolines are characterized by the following specifications vapor pressure between 385 and 490 mbar at 37.8°C, a distillation range (end point less than 170°C), freezing point (-60°C) and sulfur content of less than 500 ppm. 

Debutanized gasoline cuts from Arabian Light crude. Reid Vapor Pressure as a function of yield, weight %. Aromatics content as a function of yield, volume %. 

For these reasons, ethanol is most likely to find use as a motor fuel in the form of a gasoline additive, either as ethanol or ethanol-based ethers. In these blend uses, ethanol can capture the high market value of gasoline components that provide high octane and reduced vapor pressure. 

Amylenes. Amylenes (C monoolefins) produce alkylates with a research octane in the range of 90—93. In the past, amylenes have not been used widely as an industrial alkylation charge, although in specific instances, alkylation with amylenes has been practiced (23). In the future, alkylation with amylenes will become more important as limits are placed on the vapor pressure and light olefin content of gasolines.
