    Pump keeps kicking out

    Moreover "Just a wild thought" We should check for and eradicate any possibility of physical obstructing material as if being sucked-in at random intervals thus affecting pump out operations with increased E/power demand. Best Regards Qalander(Chem)

    Free water content in heavy fuel oil

    For a heavy fuel oil having higher viscosity we may anticipate settling out faster in case storage temperature stays around 80-85 celcius. But should be around 2 days I assume. Best Regards Qalander(Chem)

    Free water content in heavy fuel oil

    Dear, Somehow I am of the opinion that if any mixing is affected in these tanks for homogeneous intake for pumps and indirectly supporting uniform calorific value. Then the water/water vapors are bound to find their way into the storage tank's vapor space. Having said that,it is also a plausible...
