This topic discusses the concept of butane blending, Gasoline properties, and seasonal RVP specs, Blend Models and benefits calculator.
Description
RVP is enhanced due to the mixing of Butane into RFG (reformulated gasoline). There is a limit concerning RVP in gasoline. This serves as a constraint for butane blending. Because of this constraint, a refiner should do butane blending carefully. Blending benefit depends on Butane and gasoline price spread. RVP depends on temperature. RVP specs vary from summer to winter. They also vary as per the refinery location. RVP may vary from six psi to twelve psi. For N-butane, RVP may be up to 46 psi. For blending purposes, low-value normal Butane is preferred by the refiner.
