Calculation of the hydrogen-scavenging oil ratio for hydrogenation units
Thread Content
Everyone, I have a few questions regarding the calculation of the hydrogen-to-oil ratio in hydrogenation units. First of all, the hydrogen volume displayed on the gauge is in standard cubic meters; so when calculating the hydrogen-to-oil ratio, does it need to be converted into the volume of hydrogen at the current pressure? Furthermore, our setup is as follows: after the catalytic reforming reactor, the fuel enters the refining reactor together with straight fuel. Well, the hydrogen-to-oil ratio for the first reforming reactor is relatively easy to calculate, but how should the hydrogen-to-oil ratio for this refining reactor be calculated?
No conversion is needed; use the volume at standard conditions
It is then meaningless to calculate the hydrogen-to-oil ratio for the second reactor.
Why? ? ? ? ? ? ? ? ? ? ?
The purpose of evaluating the hydrogen-to-oil ratio is to assess the hydrogen environment of the feed oil and to achieve a balance between this hydrogen environment and operational energy consumption. If two reactors are connected in series, it is difficult to calculate the hydrogen-to-oil ratio for the second reactor; unless done by research departments, this will not provide any practical guidance for production.
Is oil also measured by volume flow rate? I’ve also been struggling with the issue of how to calculate the hydrogen-to-oil ratio. Additionally, I’m not sure whether the amount of recycled hydrogen refers to the amount that enters the reactor after mixing with the oil, or something else Does this count as the amount of rapidly cooled hydrogen? Please give me some advice! Thank you!
The hydrogen-to-oil ratio only needs to be kept within a certain range; it is also difficult to use as a means for adjustment in terms of operation, and the volume can simply be calculated based on cubic meters
No conversion is needed; simply multiply the standard cubic volume of hydrogen by its purity and divide by the volume of the feed oil
Catalyst hydrogen-to-oil ratio in the bed = (amount of recycled hydrogen + amount of cold hydrogen) ÷ amount of hydrogen feed (v)
