Why is the difference between rich and lean liquids so large in MDEA amine-based desulfurization?
Thread Content
In the dry gas desulfurization system, the flow rate of the rich liquid is 62,000 kilograms per hour, while the flow rate of the lean liquid is 12,000 kilograms per hour. Could you explain it?
I hope someone knowledgeable can provide an answer. . . .
Is there a problem with the flow meter? Or is there an error in the instrument configuration? Theoretically, there shouldn’t be much difference.
Reply to 3# superclaus-user: No, that’s exactly the format of the data provided. Moreover, there is little lean liquid, and it’s not possible to connect the lean liquids in parallel.
For this system, information such as whether it was put into operation after the commissioning of a new production unit or after the modification of instruments needs to be provided in detail in order to conduct an analysis. Otherwise, it’s impossible to say anything; it’s like saying that someone is unwell – no matter whether you consult experts or professors from within the country or abroad, they won’t be able to determine what disease the person has and how to treat it based on such information alone.
I think there are several possibilities for this: 1. There is a problem with the flow meter; depending on the type of flow meter, significant issues may arise that cause variations in the flow rate. Because in principle, there shouldn’t be such a large difference between the two traffic volumes. 2. There is a possibility of medium cross-contamination; a composition analysis of the lean and rich amine solutions can be performed to examine the concentration differences. Check whether steam from the scanning process or other substances have entered the amine solution system, resulting in an excess of amine solution.
If the flow meter is fine, check the process!
There should still be some semi-poor liquid left. Please check carefully!
The simplest method is to measure the concentrations of the rich and lean fluids; if the difference in concentrations is not significant, then it’s a problem with the flow meter. The likelihood of a problem with the flow meter is 99%. 9%. Another possibility is liquid leakage; however, if that occurs, the concentration of the lean liquid will drop rapidly. The product quality must be substandard.
Is the amount you gave a stable value? Or an instantaneous value at some point?
Yeah, we can’t just let the original poster drink it.
