    Low Sulfur Fuel Oil

    gladken, Get the full chemical analysis of the FO from your vendor. After doing a combustion analysis, this will tell you what the ash is and how much is generated per pound of fuel combusted. Better yet, get the vendor to do it. Hope this helps. saxon

    rough estimate of bubble velocity

    gmorin, volume flow is volume flow (cfm). Cut off the flow, volume goes to zero. Convert gas volume to liquid volume and this is the volume you lose. Hope this helps. saxon

    Concentration of Salt Stream

    Volunteer, You may want to take a look into Ultra-filtration/RO. Based on your flow rate, you're only looking at approx. 3.5 gpm which is well into the range of smaller UF/RO units. As for crystallizers, this is awful far down in their operating range. Hope this helps. saxon

    P&ID Standards

    Procman, In the interest of saving drafting hours and ease of making revisions; I prefer the simple, "From Dwg. xyz" or "To Dwg. zyx" (both based on direction of flow). When tied to a specfic Equip. No., when revisions come down the line over the years,which they will, it makes revising the...

    Pump Replacement

    Tomfitz, You can utilize the Pump affinity laws to check the comparison. Better idea, demand the Manu'f. pump curve for the pump in question. No curve, no problem, the pump doesn't come into the plant. Hope this helps. saxon

    Pump efficiency , old x new ?

    dkf, There have been some minor hydraulic improvements in impellor design and at the suction impellor eye(due to CFD). The real cost savings have come about in the development of Hi-effciency motors and the implementation of VSD's. Hope this helps. saxon
