To control our # 6 oil viscosity, we can cut with the following cutterstocks,
crude unit diesel flash ~ 180 °F
merox kerosene flash ~ 160 °F
distillate hydrotreater diesel flash ~ 180 °F
visbreaker gas oil flash ~ 190 °F
At times, usually when...
Can anyone help me determine pump mini flow requirements.
I would like to verify the pump vendors recommendation of 60% of rated flow. The pump manufacture is basing this not only on protection the pump under closed discharge conditions but also for radial & axial thrust affecting mechanical...
