    Pumping Sludge -10% solid

    For high content of solids in a system, you might need empirical formulas. Suggest you contact specialists in handling sludge and solids. They should be able to recommend pumps, piping, etc. See http://www.toyopumps.com Alfonso

    Addition of polymers to reduce pressure drop

    The use of Drag Reducing Agents (DRAs) is an excellent method to increasing the flow rate in crude oil pipelines. The effectiveness of the method depends on the type of crude oil. DRAs seem to be a cost effective solution for low viscosity, >24 API crudes. It seems that the only way to be sure...

    Viscosity of a crude oil blend

    Good discussion here. At the end of the day, I decided to prepare a spreadsheet for calculating the viscosity of a blend of crudes based on the W.A. Wright method, as described on the Guide to Petroleum Product Blending. This method requires knowing viscosities (cSt) at two different...

    Viscosity of a crude oil blend

    Would anybody point me to a book/journal/article where I can find a correlation for estimating the viscosity of a blend of two crudes? Let's say I have a blend of 80% of a 19 API at 160 F and 20% of a 30 API at the same temperature. Your help would be much appreciated. Regards, Alfonso
