Baker Petrolite FOAMSTOP 5000 Low Catalyst Impact (LCI) Antifoam Reduced Silicon Carryover
Baker Hughes improved refinery operationA Midwest US refinery using a 600,000 cSt antifoam in their delayed coker was experiencing silicon carryover in the streams exiting the main fractionator. Base case coker liquid product samples were collected at identical periods in the drum cycles while filling both Drum A and Drum B.
Drum A samples showed silicon levels of 58.0 ppm, 38.8 ppm and 5.5 ppm in coker naphtha, LCGO, and HCGO, respectively. Drum B samples showed silicon levels of 33.8 ppm, 28.7 ppm and 1.8 ppm in coker naphtha, LCGO, and HCGO, respectively.
Baker Hughes representatives were asked to collaborate with the refinery staff to review the system and then present recommendations. After a joint analysis by both parties, it was agreed that a newly developed product, Baker Petrolite FOAMSTOP™ 5000 low catalyst impact (LCI) antifoam, would be evaluated. Additional sets of naphtha, LCGO, and HCGO samples were collected to monitor silicon levels, using the same sampling protocol developed to generate the baseline data.
