Propane demand is expected to be 110,000 barrels per day lower on average in 2014 compared to 2013 because of reduced demand from petrochemical plants, according to EIA's Short-Term Energy Outlook. In contrast to propane used as a heating fuel in buildings during colder months and as a crop-drying fuel during the harvest season, both of which are highly seasonal and weather dependent, petrochemical consumption of propane has relatively little seasonality.
