Purchasing new glycol can be expensive. Beyond the initial purchase cost, the expenses for disposal and transportation of contaminated glycol can quickly escalate.

One of the most significant costs for gas producers when replacing contaminated glycol is the revenue lost due to downtime and production interruptions.

Additionally, these expenses do not account for the substantial costs of using steam cleaners or chemical agents to prevent re-contamination of the new glycol.

Natural gas processing companies have two options for replacing contaminated tri-ethylene glycol:

Run a Vacuum Distillation Unit

Purchase Costly New Glycol

Combat Expensive New Glycol Purchases

By opting to distill existing glycol, immediate cost savings are recognized.
  • Costs about half the price of new glycol
  • Drastically reduces waste disposal to just a few drums
  • Absolutely no downtime
At Pristine Alliance, we strive to deliver an inexpensive and environmentally friendly solution that extends the lifespan of TEG in dehydration units. Our distillation unit is straightforward to connect, requiring only three connections: glycol inlet, glycol outlet and a fuel source.


The Pristine Process

Used glycol is pumped into our system, where it is heated and subjected to vacuum distillation.

During this process, several key benefits occur:

Vacuum distillation enhances the relative volatility of key components, improving their separation with fewer theoretical stages.

The reduced pressure minimizes degradation and polymer formation, thanks to lower bottom temperatures and shorter mean residence time.
Capacity, yield and purity are increased.
The distilled glycol is then pumped back into the operating system. Our distillation unit effectively removes chlorides, hydrocarbons, solids and well-treating chemicals as well as impurities with salts and degraded glycols within our system. This reduces waste disposal by up to 97% and restores the glycol to 97-99% purity, enhancing its hygroscopic properties and overall dehydration performance.

TEG dehydrators are essential for preventing hydrate formation in pipelines. When properly maintained and operating at peak efficiency, they provide a reliable and cost-effective method for gas dehydration.

We work closely with our clients to offer the most cost-effective solutions for maintaining their dehydration units. By utilizing our patented vacuum distillation unit, you can significantly improve your bottom line.
