Blending of gasoline with butane is a common procedure to increase the RVP. The desired volatility of a gasoline blend is entirely linked to the ambient temperature. In hotter climates, gasoline components with lower volatility than in cold climates should be used. In cold climates insufficient volatility results in cars failing to start. Excessive volatility in hot climates causes a “vapor lock”. Here combustion fails to occur, because in the fuel lines the liquid fuel changes into a gaseous fuel, that operates the fuel pump ineffectively  and starves the engine of fuel.

Beacon 3000 NIR process analyzer has the capability to measuring this scope of different physical properties, also where butane is added to the gasoline, throughout the entire  blending operation.
