It seems there is no calculation table available yet; let’s gather the commonly used formulas and turn them into a calculation table so that it will be convenient for everyone to use. Examples of the formulas are as follows: 1. Circulating hydrogen volume in the unit = (Hydrogenation feed × Hydrogen-to-oil ratio) / Percentage purity of fresh hydrogen. 2. Hydrogen-to-oil ratio in the unit = (Circulating hydrogen volume / Hydrogenation feed volume). 3. Hydrogen-to-oil ratio for the catalyst bed = (Circulating hydrogen volume + Cold hydrogen volume) / Hydrogenation feed volume. 4. Hydrogen partial pressure in the unit = (Reactor pressure × Percentage purity of circulating hydrogen). 5. Unit space velocity (per hour) = (Hydrogenation feed volume) ÷ Catalyst loading volume. Prizes are available for useful formulas; those that are particularly useful will be rewarded with 20 wealth points~~~~
Hydrogen partial pressure = Total pressure * Volume fraction of hydrogen among all gas molecules
At that time, the Topsox catalyst told us that the available hydrogen ratio = amount of pure hydrogen entering the reactor ÷ amount of new hydrogen; what is the ultimate purpose of this value?
