Refinery LPG Slip Stream Test

Gulf Coast Refinery



Petromax Refining Company is a new refinery in Houston that is experiencing high levels of black powder contamination in its’ incoming product streams. Black powder in the LPG product stream on the outlet of the cracker column lowered its quality and product value.

BPS Magnetic Separator 1” OD x 3 ½” L
Slip Stream Size ½”
Slip Stream Flow Rate 5 gph
Temperature 145° F
Test Duration 14 days
Black Powder Collected 18 g
Sample Size 9.58  g
Particulate Size 1-100 microns
Particuate Composition 50.5% Iron

23% Iron Sulphate

21.5 Sulfer

5% Magnesium, Calcium,

Silica, and Aluminum.


A BPS magnetic separator was installed on a slip stream downstream of the cracking tower, and downstream of traditional filters to compare filtration efficiencies.



The test was successful; the magnetic separator element captured significant amounts of ferrous and non-ferrous contamination missed by the conventional filters.
