A Saudi Arabian energy pipeline company understands the problem of increased Black Powder in an NGL pipeline after the completion of the pigging process.
Traditional depth filtration is inefficient in removing Black Powder to sub micron levels, this filtration prematurely loads with Black Powder.
The main source of Black Powder in this application results from the pigging process. The scraping of the pig along the pipeline wall increases the amount of highly ferrous Black Powder in the NGL system. This Black Powder impedes the refining processes and causes premature wearing of all the components within the fractionation facility such as valves, meters, and compression units. Finally, this contamination devalues the end product.
The company agreed to test a BPS Magnetic Separator Rod (2”OD, 26” long) in a slip stream off a 14” diameter pipe downstream from the pigging process.

On average, 12.5 g/day of Black Powder passed through the 1” line on the test skid. By mass it can be approximated that the BPS Magnetic Separator test skid would run for 232 days before reaching 2900 g and still register a 0 psi differential; along with the ability to collect another 2900+ grams depending on the density of the Black Powder particles before cleaning is required.
*The TDM reached its 25 psi limit within 8 days as shown in Test #5 and as a comparison to the BPS MS in Test #6 would equate to the replacement of 29 TDM filters in 232 days.
This BPS Magnetic Separator has shown its ability to capture ferrous and non-ferrous contamination without flow restriction. The BPS system is capable of capturing a higher proportion of solid particles over a long duration with minimal flow restriction and stress on pumps.
