Gasoline blending in the oil & gas industry

High accuracy flow measurement

Gasoline blending is a refinery operation that blends different component streams into the various grades of gasoline required in the final products. The two properties of major importance are the octane number (indicating how much compression the fuel can withstand before self-igniting) and the Reid Vapour Pressure or RVP (indicating the volatility of the product). The RVP may vary between seasons, as the products will be less volatile in winter, when it is colder.
