Reid vapour pressure definition

Reid vapour pressure means the vapour pressure of a liquid as determined by laboratory testing in a standard manner in the Reid apparatus;

Reid vapour pressure. , of petrol, means the petrol’s volatility at 37.8ºC measured using—

Reid vapour pressure or “RVP”: means the absolute vapour pressure exerted by a liquid at 100 °F (37.8 °C) as determined by the test method ASTM-D-323;

Examples of Reid vapour pressure in a sentence

• The vapour pressure of gasoline is usually determined using the stand- ardized Reid method (SS-EN 13016-1) in which the vapour pressure of petroleum products is determined at 37.8°C (100°F), it is thus called the Reid vapour pressure (RVP).

• Ethanol has, to date, been the renewable fuel of choice to substitute fossil gas- oline, but isobutanol may well be a better option due to its higher carbon-to-oxygen ratio, high energy density and low Reid vapour pressure.

• The amount of solution gas or product volatilization per unit oil production is determined from the change in product vapour pressure between the inlet separator at the field production facility (i.e., the vessel operating pressure) and the refinery inlet (e.g., a Reid vapour pressure of 30 to 55 kPa).Although the simple mass balance using national production statistics is a crude indicator of fugitive methane losses, it offers a greater degree of confidence than that offered by the Tier-1 approach.

• The higher alcohols (propanol, butanol and pentanol) on the other hand, provide better water tolerance, volatility control and lower Reid vapour pressure (RVP).

• Its Reid vapour pressure at 37.8°C is 65.5 Kpa (Pyzuir, 2015).Condensates can be either recovered from gas processing plants, after being processed from raw natural gas or from oil and gas field wells.

• ASTM distillation, Reid vapour pressure (RVP), Gum content (existent), Smoke point, Aniline point, Flash point, Moisture content by Dean & Stark method, Kinematic viscosity by Dynamic viscosity; Redwood viscometer, Pour point, Conradson / Ramsbottom Carbon residue, Rotational viscometer.

• The effects of ethanol addition on Reid vapour pressure (RVP), antiknock quality and tailpipe exhaust 14emission of the oxygenated and non-oxygenated gasoline blends, were investigated.

• Two modeling differences are that we fixed the constant κ = 1 and, hence, the coefficient vector is β = (3, 3/2, 0, 0, 2, 0, 0, 0) and varied the signal-to-noise ratio by increasing the scale parameter σ from one-half to two in increments of 0.5. We again used an autoregressive design for the matrix of predictors.

• Two hydrocarbon test fuels, designated G-RS-1 and G-RS-2 were employed to study the effect of added ethanol on 128the Reid vapour pressure (RVP) and octane numbers (O.N) of these fuels.

• NOTE - The approximate relationship between temperature, Reid vapour pressure, and explosive limits of petroleum products is given in figure 2.
