    Air Separation Unit

    I have information on an existing ASU inland at a barometric pressure level of 0.86 bara at a specific oxygen purity and producing 3000t/d of oxygen. I also have the cost of such a unit assume x million $. I need to move this ASU to the coast where the barometric pressure is 1 bara and it...

    Cooling water pump

    A pump was installed which takes suction out of the existing cooling tower sump. A civil channel was created to supply water to the pump sump from where the vertically installed centrifugal pump takes suction. The pump is cavitating. Flow rate 1800 m³/h. How do I calculate the friction loss...

    CO2, Potasium Carbonate System, V2O5 as corrosion inhibitor

    I need to understand and I need to know when and how the chemical reactions occur between Fe and V2+. I am looking for the corrosion meganism. Secondly, what would be the maximum velocity of the gas stream through a column that would cause the vanadium protective layer to dissapear due to erosion?

    Hot Carbonate System CO2 removal from Synthese Gas

    I want to thank TBARBill & Art Montemayor for their feedback. I appreciate it. Maybe just to clarify my own position. I am coming from a crude oil refinery and the pure chemical process engineering slightly different but I would assume that it is all the same at the end. My objective is to...

    Hot Carbonate System CO2 removal from Synthese Gas

    We have an UOP Benfield process installed in our plant. The process or unit description is Benfield "Modified hot carbonate gas treatment system" We are sending a LPG stream through the Benfield process to absorb the CO2 before it enters a cryogenic process. The gas is coming from...
