Longeron,
An accumulator is also considered for the reason that you indicate. Seal vendor also recommend it to damp the pressure pulsation of the screw pumps. Those pulsations may cause damage to seal metal bellows.
Regarding to point 4, we will use a back pressure control valve and not a...
Hydrocarbon coking is a thermal conversion of heavy oil to lighter products and petroleum coke, a solid product. As hydrocarbon leak through the hot seal faces it takes temperature and coke could be formed.
Steam quench (Plan 62) is specified to cool the atmospheric leakage and prevent coke...
Thanks for your comments Flexibox.
Here some more details:
-Water coolers will be used. It’s also required that barrier fluid be at maximum 60ºC, so water fouling should not be a problem.
-Ok. It’s considered to uses Royal Purple 910.
-Seals will be metal bellows, face to back configuration...
We are implementing at our Refinery Plan 54 on pumps that handle heavy hydrocarbon products at high temperature. (Heavy Vacuum Gas Oil, Reduced Crude, Pitch, Tar, 260ºC-360ºC)
Based on the experience at other Refinery and the recommendations posted in this forum we have specified one console...
