Mono Ethyl Glycol (MEG) and Tri Ethyl Glycol (TEG) are widely used for hydrate inhibition in production lines and well shut-ins. However, its effectiveness can deteriorate over time due to contamination with water, scale, rust and break down products from biological activity. Contamination often consists of divalent ions such as Calcium, Magnesium and Iron along with Glycolic and Oxalic acids that inhibit the normal action of the MEG or TEG.
ABCAN has developed a patented system for the regeneration of MEG and TEG. The systems saves expenditure and the logistics involved in the disposal and replacement of the contaminated product.
How Does It Work?
The Glycol recycling process comprises of the following stages:
• Initial Filtration to remove any suspended solids down to 25 microns.
• The acids are then absorbed onto a fixed bed media. The acids are absorbed as a magnesium silicate salt on the media bed.
• The next step is the chelation of the divalent ions onto the fixed bed media.
• At this point the only contaminate left is water which can either stay in the mixture or can be distilled off
according to customer requirement.
• There is also an option to remove radionuclides and Lead if required.
Allows MEG and TEG to be regenerated and reused without
removal from site.
• Saves on further purchase of MEG and TEG and disposal costs.
• Fully automated with minimal manpower requirement.
• High throughput (up to 80m3 per hour).
• Option to remove water.
• Additional options for the removal of monovalent ions such as Sodium (Na), Chlorine (Cl) and Potassium (K).
• Additional options for the removal of NORM and Mercury (Hg).
• The ABCAN system has proven commercial benefits over other available systems.
Additional Waste Treatment
ABCAN can treat or remove various chemicals and contaminants including:
- Hexavalent Chrome (Chrome vi)
- Iron (and Iron Cyanide)
- Radioactive Material
- We can treat waste with emulsions and reverse emulsions
