Ion Exchange Acid Control Technology

Ion Exchange liquid separation technology has been in use for decades in a wide variety of industrial applications including chemical processing, waste water treatment, demineralization, heavy metal recovery, and acid removal. Ion exchange technology acts like a “chemical sponge" and is based upon the electrical attraction of oppositely charged matter (ions) to selectively attract and remove a particular contaminant or species of interest. Some of the industries that rely upon ion exchange technology to solve demanding problems include the Nuclear, Mining, Chemical Processing, Power, Pharmaceutical, Wastewater and Food processing industries.

Ions are electrically charged atoms or molecules that have either a positive (cation) or negative (anion) charge. As a compressor’s fluid oxidizes, it produces carboxylic acids comprised of positively charged Hydronium ions. When oil containing these charged acid molecules comes in contact with Fluid Metrics’ proprietary ion exchange media, the acids are attracted to and adsorbed by the anionic media and are physically removed from the oil. Harmful acid molecules become permanently bonded to the disposable media which neutralizes the acid and controls the fluid’s Total Acid Number (TAN) and pH. Unlike Fullers Earth and some other acid removal media, the Fluid Metrics media acts as a one-way acid adsorber where nothing is released back into the oil that could change or otherwise harm the oil.

The ion exchange technology used in Fluid Metrics’ COP was originally developed, tested and proven by The Dow Chemical Company, makers of Ingersoll Rand’s Ultracoolant™ and Sullair’s Sullube™. Dow Chemical, in addition to being the world’s largest manufacturer of synthetic compressor fluids, is also a world leader in ion exchange liquid separation technologies. Relying on their in-depth knowledge of the chemistries of both technologies, Dow conducted nearly three years of extensive testing to determine the effectiveness of ion exchange technology at removing acids from a variety of industrial lubricants. Included in their testing were today’s most common base stocks of polyglycol, PAO, and ester blended synthetic fluids as well as mineral based oils. The results of Dow’s testing proved this ion exchange technology to be “extremely effective at removing acids and controlling TAN and pH in these lubricants". Dow further determined that this ion exchange technology, “did not contaminate or otherwise harm the treated lubricants in any way" and, that “Based on our testing and unique knowledge of both ion exchange resins and synthetic compressor lubricants, Dow fully endorses this technology for use in the purification of the above mentioned rotary screw compressor lubricants."

Ion Exchange technology has been in use since the early 1900’s to purify and remove dissolved contaminants from potable water.

In recent decades, high performance synthetic ion exchange media was developed for purification of fluids used in the Nuclear Power, Petrochemical, Mining, Pharmaceutical, Chemical Processing, and Food & Beverage industries.

In compressor fluid applications, the ion exchange media acts like a one-way acid adsorber to selectively attract and remove acids from the oil.

In some ion exchange processes, water is released back into the fluid.  However, with Fluid Metrics' proprietary drying process nothing is released back in to the compressor fluid.

The ion exchange technology used in Fluid Metrics' COP has been extensively tested and endorsed by Dow Chemical, the world's leading supplier of synthetic compressor fluids.

According to Dow Chemical, ion exchange technology is "extremely effective at removing acids and controlling TAN and pH" in compressor fluids.

Ion exchange technology will not remove the additives used in compressor fluids and will not contaminate or otherwise harm the fluid in any way.
