    Estimating heat transfer coefficient in a forced convection oven

    I would like to estimate heat transfer coefficient in a forced convection oven that is open on both ends. Oven has multiple heating zones, with zone 1 at 170 degrees C, zone 2 at 180 and zone 3 at 200. This temperatures may change depending on the batch running. I understand the heat transfer...

    Thermodynamic model for hydrometallurgical reaction

    H2PtCl6 + 6NaNO3==>6NaCl +2HNO3 + Pt(NO3)4 happens under fusion at about 500 degrees. Does anyone know if this reaction can happen in aqeous form? Meaning reacting aqeous H2PtCl6 and NaNO3 in a heated vessel and stirring. Tried to find sources for this information but helpless. Is there a model...

    Removal of dissolved NaCl from 10-16% PtN solution?

    I am presently trieng to figure out the removal of NaCl from PtN solution. No hydrocarbons as carriers if you're planning liquid-liquid extraction, PtN is a good oxidising agent and u'll be cooking up an explosion. I wanted to take advantage of the eutectic mixture, by adding more NaCl, drop...
