Jet A-1 contamination
Jet A-1 contamination
(OP)
Hi again!
I am researching the possibility of multi-product pipelines, and need to know how much diesel (gasoil) or gasoline (mogas) is alllowed to contaminate Jet A-1. From what I've read, it seems the limiting factor may in fact be the water in the diesel and gasoline, rather than the products themselves (water must be below 30ppm in Jet A-1). Can anyone provide some insight? Thanks!

RE: Jet A-1 contamination
Separation between similar products, gasolines, or distilates is always maintained and relatively no mixing is allowed. Gasolines of different octanes that are mixed in between batches producing an interface mixture can be carefully injected into the lower quality fuel. Gasolines of 92 Octane can be injected into gasoline of 87 octane, but not vice versa. Ultra low sulfur diesel can be injected into Low sulfur Diesel. Jet can be injected into diesel. No gasoline can be injected into jet or diesel, or visa versa.
Initial segregation of fuels is normally accomplished by specific gravity. Gasolines are lower than 0.76 Kerosene between 0.76 to 0.82. Jet 0.82 to 0.85, Diesels can range from 0.85 to 0.96
Other limits can apply such as vapor pressures, viscosities, pour point temperatures, freeze temperatures and even color. Vapor pressures are different between summer and winter grade gasoline mixes in many countries. It may not be a good idea to mix those at all.

There are numerous and extensive specific ASTM specs that can be applied in each case.

Thanks for the info! You seems to always have the information that I need :)
RE: Jet A-1 contamination
There was sometimes mixing of gasoline into diesel, and jet a1 into diesel, but as refining limits have got tighter, the allowable percent mix of contamination has reduced over the years. Each shipper has different allowances but you're generally into fractions of a percent of the total parcel or tank volume.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way

Here's Colonial Pipeline's Product specification list. It's 78 pages long,
