Degradation of Glycerin
Degradation of Glycerin
(OP)
I am in the process of designing a flow test loop using glycerin as a standard fluid. The stand will be dedicated for pure glycerin only, so the plan is to leave lines and tanks filled when not in use. Should I expect significant degradation of the fluid or line components from prolonged exposure? Is there a metric showing if or how much water pure glycerin can scrub from the air in humid conditions? Microbial growth? To maintain the stand properly, viscosity and density need to be readily controlled. If I can predict a degradation of these properties, then I can devise a fluid change-out plan and cost estimate.

acceptable and design the measures to assure that the
water adsorption is controlled.
I experienced microbal contamination of diluter glycerin --
I don't know if it may be a problem in the case of higher concentration.

It has been reported that glycerol is so hygroscopic that when having a film on the skin and the air's humidity is less than 65%, it may absorb the moisture from the skin drying it.
