I was wondering if a dryer is ever placed before the compressor? For limiting the presence of water vapor before the compressor inlet, I was thinking of drying the air before the compressor (it's a closed system btw). Is this the right technique? Or you this be done otherwise?
Apparently, there are two dryers after the compressor( a knock-out drum is in between the compressor and dryers). Would a solution to get the water out properly be that the dryer is placed before the compressor?
I found that they use the Karl Fischer method (ASTM-D6304). The values I have indicate the following: (DDMMYY)
632 ppm on 16/09/16
351 ppm on 27/01/17
640 ppm on 20/07/17
584 ppm on 25/10/17
834 ppm on 4/05/18
So, apparently there is some foaming on the oil when they change it. Which could indicate contamination from water.
Also, the problems seems worse in the summer. This could perhaps also point in the direction of bacteria. They like it warm, right?
But if the problem is water. Wouldn't the...
In the oil analysis it does sometimes show that small steel particles are present. But I don't see clear connection between the two. Sometimes the amount of particles is normal but the demister still fails.
Is it common for filters to not show any visible contamination when bacteria or fungi...
The manometer has been looked at and is not the problem.
The filter is a fiber demister pad. I can't find a link to the original filter but this link shows the filter best( first picture): https://www.demisterpads.com/demister-pad/fiber-demister-pad.html
The concern is partly the cost of the...
I'm doing an internship about mechanical maintenance. I have come to a problem that is a bit over my head. The problem was also discussed by a few process engineers but they did not come with a good solution.
So, the oil filter is part of a biogas compressor. The biogas comes from the...
