There are really no more questions; just pick any one – a question related to the quality of hydrogen
Thread Content
As the title suggests, I’m not sure what topic to choose; I’ll just pick one arbitrarily. I hope everyone will actively participate in the discussion. 1. For residue hydroprocessing, what are the target values for CO and CO2 levels in the fresh hydrogen? 2. Assuming that the total concentration of CO and CO2 in the fresh hydrogen is around 200PPM, but there is no CO or CO2 in the recycled hydrogen, then where do they go? Why? 3. What issues should we pay attention to in normal production management? Those who participate get 10 wealth points; those who give good answers get 20 wealth points. Yay!
1. In residue hydrogenation, the levels of CO and CO2 in the fresh hydrogen must generally be kept below 10 ppm to ensure a clean and efficient refining process. 2. If CO and CO2 are present in the fresh hydrogen but not detected in the recycled hydrogen, these gases may have been converted or absorbed by the catalyst. For example, during the hydrogenation process, CO and CO2 may react with hydrogen to produce water and methane. 3. In normal production management, attention should be paid to equipment maintenance, quality control of raw materials and products, environmental protection measures, as well as employee safety training. At the same time, testing instruments should be regularly inspected and calibrated to ensure the accuracy of the data. .
In hydrogenation units, the control of CO and CO2 in make-up hydrogen generally requires that their levels be kept below 20 ppm. 2. If CO and CO2 are present in make-up hydrogen but not detected in recycle hydrogen, this is due to the methanation reaction
The methanation reaction requires the formation of CH4, but there’s no methane present
The methanation reaction is used to remove CO and CO2; the methyl group content in the recycled hydrogen
