Description

A survey of selected contaminante in natural gas
liquids (NGL) has been completad for the purpose of
determining whether more stringent NGL
specifications should be considered by the industry.

The survey involved the analysis of over 45 samples
from seven independent processors.

The trace
contaminants that were analyzed include olefins,
oxygenated compounds, fluoride, merciny, and arsenic.

Not unsurprisingly, the highest levels of olefins were
found in the corrmponding hydrocarbon streams, (i.e,,
propylene in the propane streams).

I he highest levels
of oxygenated compounds were found in the propane
and raw make streams.

The highest fluoride levels
were found in the gasoline samples.

And finally,for the
most part, the mercury and arsenic levels were ton
clase to the detection limita for these samples (- 10 ppb
for mercury and – 50 ppb for arsenic) to be able to
accurately determine if these contaminants were
present in any of the samples.

A more exhaustive
study would be needed to analyze for these
componente below these levels.
