Transmix is received by either pipeline or tanker truck and is offloaded through a filter and into a storage tank. Product is then pumped from the tank through another filter and into a heater. The heater powered with natural gas and the unit raises the product temperature nearly 500F, creating steam which is separated in a distillation column. The light fuel (gasoline) rises to the top and the heavy fuel (diesel) settles to the bottom of the column. A recycle stream is used to maintain temperature and quality in the column. The finished products are sampled and sent to an onsite lab for testing and certification. Once certified, the product is resold and is perfectly fine to use!
According to a timely response to our questions from Scott Dean, BP Spokesman, BP plans on having the gasoline re-processed. Many bigger terminals where gasoline is loaded have their own transmix processing areas, so in this case, BP may either sell the contaminated fuel to a re-processor, or it may have its own transmix processing facilities. That was a question we did not ask. However, once the contaminated fuel is processed as transmix, it will again meet specifications and will be safe to use in your engine, and like all gasoline sold at BP, it will have a
quality guarantee. It sure is unfortunate what happened, but at least the contaminated gasoline won't be wasted, and I'm sure a lesson will be learned.
