Chemtex’s MEG Corrosion Inhibitor is a specially formulated chemical additive designed to prevent corrosion in multi-ways. It treats the surfaces of the metal making them less susceptible to corrosion. It buffers the organic acids formed as a result of glycol oxidation. Inhibited glycol based heat transfer fluids provides corrosion protection without reducing system’s heat transfer efficiency.
It is very important to use inhibitor in glycol system to prevent degradation of glycol. Glycol in presence to heat and air degrades into five organic acids namely: Glycolic Acid, Glyoxalic Acid, Formic Acid, Carbonic Acid & Oxalic Acid. Metal acts as catalyst in un-inhibited glycol solution for the formation of these acids, which then chemically attacks and corrodes system.
Also available Pre Inhibited Mono Ethylene Glycol and normal Mono Ethylene Glycol.
Application:
Mono Ethylene Glycol Brine System (MEG)
Glycol turning Red. What does it indicate?Due to immense corrosion in system, the rust in the system metal makes the glycol turn red in colour. At this point the glycol is fouled with iron contaminants which increase the glycol degradation rate. It is important to add corrosion inhibitor to the glycol system to avoid such degradation of glycol.
Dosage :
The amount of Corrosion Inhibitor required to inhibit corrosion depends on the type of system, application, brine concentration and plant operating conditions. The specific dosage rates and method will be specified by the CSL technical representative.
Major Benefits:
- Zero or negligible loss of metal or corrosion
- Excellent heat transferability and flow rate
- Long and extended life of glycol without fouling
- Avoids leaks in heat exchangers such as PHEs
- Maintains the anti-freezing properties of glycol
- Does not form sludge, as in case of other mere pH buffers used in glycol
