Increase Crude Value by Reducing TAN
Total Acid Number (TAN) is expressed as the milligrams of potassium hydroxide required to neutralize the acids in a one-gram sample, and acts as an important quality measurement. Crude oil with a TAN value of 0.5 or greater is considered corrosive and is therefore devalued. Without neutralizing this TAN, your full crude value is slipping through your fingers.

As we neutralize the naphthenic acid trapped within crude oil, we eliminate the price cuts happening at the refinery level. Because a high TAN value in crude oil indicates increased infrastructure corrosion, refineries use this measurement to mark down the price they pay you. Avonlea can remove the undesirable acids that may be stopping you from receiving the top dollar price you should.
First, what is cavitation
Hydrodynamic cavitation is the process of vaporization of a fluid through the rapid decrease of localized pressure in a flow system, below the vapour pressure, thus creating millions of tiny bubbles.
As those bubbles collapse, very high localized temperature, pressures and shock waves are created. This high-level of energy release provides Avonlea with an excellent environment to enhance physical and chemical processes.
How Does Our Cavitation Technology Work for TAN Reduction?

How Will Our Technology Benefit Your Oil and Gas Business?
There are so many reasons to use our TAN removal system:
First as mentioned, a high TAN value indicates the presence of harmful components, which in a refinery leads to corrosion problems. Since many facilities process thousands of barrels of high TAN crude each day, these high levels of naphthenic acid reduce the recovered sales prices ranging between $1.15 – 10.73/bbl.
When expanded in real terms, that means for every five thousand barrels of high TAN crude sent to refineries each day, this would equate to a minimum of $2.09M/year lost to high acidity.

In addition, our cavitation technology will benefit your facility’s processing and save you money on operational costs in the following ways:
- Product will be a higher grade crude, with increased market value
- Produced oil will be clean, and non-acidic
- Opens you up to a broader sales market
- Reduced facility corrosion
- Decreased stress on equipment, fewer breakdowns, less maintenance and reduced downtime and loss of production at output
- Zero environmental impact
The TAN Reduction Service We Offer
The good news is that we don’t hand over expensive complicated machinery and leave you to figure it out on your own. Instead, we do the processing for you so all you need to do is reap the benefits.
Our equipment is compact and efficient and adapts easily to all facilities where it can be utilized, not to mention that our people are knowledgeable and courteous and will work with your company every step of the way.


Other Services We Supply
Our service is extremely effective at TAN reduction, but we are branching out in other areas.
