How to calculate the hydrogen-to-oil ratio in gas-phase reactions
Thread Content
In the gas-phase hydrogenation process, given the saturated vapor pressure of the feedstock, how can the minimum molar ratio of hydrogen to feedstock be calculated to ensure complete vaporization of the feedstock at the specified reaction temperature and pressure?
If you calculate the molar ratio, it is the same in the gas phase and the liquid phase. Because the amount of substance is independent of state. You mean the volume ratio, right?
A volume ratio that results in a gaseous state is also acceptable; this issue can be reduced to determining, at a specific pressure, the temperature at which the dew point of the raw material is reached, that is, the temperature at which the raw material precipitates out in hydrogen.
