Extend the life of your ion exchange resin up to four times

Since Eco2Pure™ market entry 6 months ago, it has proven to be an attractive purification solution to biodiesel producers of all levels.

But did you know that Eco2pure™ can also be used to extend the life of Ion Exchange resins?

Here are five great reasons to use Eco2Pure™ to extend the life of your ION exchange resins:
A. Reduce your resins waste stream & disposal costs. Remember Eco2Pure™ has additional uses.
B. Reduce biodiesel soap levels prior to contact with the resins.
C. Reduce the overall TAN content of your fuel.
D. Extend resin life up to 4 times.
E. Enjoy huge savings as a result.

Recent field trials and case studies have shown that Eco2Pure™ will extend the life of resins significantly. Up to 4 times!

Eco2Pure™ powerful soap removal capabilities and low cost operating costs make it the natural choice to act as a guardian to the resin tower.

Typically, resin towers are configured in a lead/lag arrangement with the lead tower doing most of the dirty work and the lag tower performing the final polishing function.

So why is the Eco2Pure™ so effective at extending resin life?

Typical biodiesel made from UCO can have rather high soap levels ranging from 1500-3000 ppm.

Most gel type Ion exchange resins are capable of trapping soap molecules on the surface of the resin bead.
There are several such resins on the market all of which function differently and all of which create a new waste stream. Another great reason to pro-long their life.

There are several resins available on the market today. Each of these resins function slightly differently. They all work to remove soaps from biodiesel, but they may not be economical using standard processing techniques.

ION exchange resins are designed to work best on biodiesel with less than 500 ppm soap.

Lets put that into context:

Commercial producers using virgin oils may be able to meet the 500 ppm soap in unwashed biodiesel.

Producers using used cooking oils (WVO) will have 3-6 time this amount of soap in their biodiesel. That is 1500-3000 ppm soap. This means the resin will exhaust 3-5 times faster. Therefore to make resin use viable, an additional wash method is advisable upstream of the resin tower.

Resins operate by removing the soap by replacing the metal ion in the soap with a hydrogen forming FFA that is passed through the resin and left in the biodiesel. This means that if you have high soap levels this will result in a high acid number.

So by using the Eco2Pure™ upstream of resin systems to remove excess soaps, you will not only significantly increase resin life and reduce renewal costs, but also keep the TAN (total acid number) in specification.

So why do Ion Exhange resins need to be protected?
Two traditional problems that resin systems experience are compaction and fouling.

Compaction is caused when the beads grow in size over their normal lifespan and do not move up the tube adjusting for an increase in size. Compaction can cause ruptured resin tubes, burst resin beads, and decreasing flow rates.

Fouling is a coating on the top layer of the resin with contaminants like glycerin or undissolved soaps that result in flow stoppages. Fouling can be prevented by giving the biodiesel enough time to clear before passing over the resin bed.
