When you keep your GLYCOL SYSTEM working properly you will avoid many operational problems such as hydrate formation (icing-up of equipment at temperatures as high as + 15 degree Celsius), corrosion (because water was not removed), and even slugs of water in pipelines.

Glycol is the blood of a glycol system, keep it clean by proper filtration in a (5 micro metre type) full-flow filter. CLEAN THE FILTERS BEFORE THEY CLOG-UP. You will know WHEN by watching the pressure-differential across the filter (if the pressure differential stays at 0,1 bar or less for months you better call in the maintenance man to repair the by-pass valve, the meter or put the filter elements in the correct way into the filter body). MONITOR GLYCOL QUALITY. Fire the operator that puts the filter on by-pass because it is too much bother to clean them.

BUT WAIT before firing the operator (previous point) check whether the filter is properly designed, because if it has many bolts in the flange to keep the lid on the filter it is the designer that should be fired and the filter replaced with one that has a quick open type lid. (This of course only when the pressure is near atmospheric, as it often is in the filter). See drawings.

Most of your pump wear problems will be solved by proper filtration of glycol to remove SOLID PARTICLES.

Salts and other SOLUBLE material that inevitably accumulates in glycol over time will give problems, such as foaming, unless one drains and replenishes the glycol regularly. For good reasons we try to reduce glycol entrainment losses and losses through leaks to a minimum, but at the same time we thus keep all soluble undesirable material in the system. (NOTE that systems with uncontrolled high glycol entrainment/losses, thus high operating costs, have often GOOD GLYCOL QUALITY, because it gets rid of its soluble undesirables regularly by leaks.)
