Dear PEI Member:
Most TulsaLetter readers are aware that a 15 parts per million (ppm) sulfur specification, known as Ultra Low Sulfur Diesel (ULSD), was phased in for highway diesel fuel from 2006 to 2010. Diesel engines equipped with advanced emission control devices (generally, 2007 and later model year engines and vehicles) must use ULSD fuel. As a result, exhaust emissions from these engines are decreased by more than 90 percent—a very good thing.
It was anticipated that the change to ULSD would impact lubricity, energy content, materials compatibility, and microbial growth. However, accelerated and increased corrosion of diesel storage equipment was not foreseen as a likely outcome. Unfortunately, as we are all painfully aware, severe and rapid corrosion has been observed in systems storing and dispensing ULSD since 2007—an unintended consequence of reducing sulfur in diesel.
Now let’s consider the changes about to be made to gasoline. Beginning in 2006, new Tier 2 regulations lowered the vehicle standard for sulfur in motor gasoline in stages to an average of 30 ppm, with an absolute cap of 80 ppm, down from the previous standard of 300 ppm—a 90 percent reduction. But in an effort to increase the effectiveness of the catalytic converter, which eliminates nitrogen oxides, hydrocarbons and carbon monoxide, EPA has proposed Tier 3 standards that will reduce sulfur in gasoline even further. The proposed standards, which allow federal gasoline to contain no more than 10 ppm sulfur on an annual average basis by January 1, 2017, are expected to be finalized soon.
Talking to tank owners and contractors in the field, there were no adverse consequences to equipment when the country moved from 300 ppm to 30 ppm. But what will happen when we move from 30 to 10? Has the question been asked? Has the effect on equipment been studied? Do the people proposing the sulfur reduction in gasoline know about the industry’s ULSD experience? Or are we just going to cross our fingers, hope for the best and deal with the problem if equipment that stores 10 ppm sulfur gasoline also starts to corrode more quickly.
