Normal butane is an important gasoline blendstock, with a great combination of high octane and relatively low cost. It also has a high Reid vapor pressure, or RVP, which is a good news/bad news kind of thing because while regulators allow higher-RVP gasoline — that is, gasoline with higher levels of butane — to be sold during the colder months of the year, they forbid its sale during the warmer months, thereby forcing butane levels in gasoline to be kept to a minimum. As we discuss in today’s RBN blog, air-quality regulations and seasonal shifts in butane blending may add complexity to gasoline production and marketing, but they also create opportunities to increase gasoline supply and earn substantially larger profits through much of the year.
