Lanlang Biodiesel Purification Dry Ion Exchange Resin

LANLANG CA005DR is a special commercial grade dry wash ion exchange resin that can be used to remove impurites from Biodiesel after the glycerin has settled and been removed. It works extremely well at removing soaps, catalyst, glycerin, and even water. When used as recommended and in tandem with a demethylation system, it can allow you to remove the contaminant levels in Biodiesel down to ASTM specifications.

Physical Properties
LANLANG CA005DR Ion Exchange Resin consists of tough spherical beads that have an average particle size of 400 microns (dry), and a range of 350 microns to 500 microns. It weighs 7.6 pounds per gallon, or 56 pounds per cubic foot (dry). Note! The individual beads will swell to more than twice their size when exposed to water, methanol or glycerin. It is very important to size the dry wash towers properly so that there's enough room for the beads to swell without rupturing or damaging the dry wash towers.

How It Works
LANLANG CA005DR resin is placed inside of a holding vessel. Typically the vessel employed is tubular and is referred to as an Ion Exchange Dry Wash Tower. The resin beads, when deposited in the column, form a "resin bed" at the base of the vessel. Unnwashed Biodiesel is then pumped through the vessel and through the ion exchange resin beads.


As the Biodiesel flows through the LANLANG CA005DR resin beads, the impurities are removed and the Biodiesel is purified. The LANLANG CA005DR resin purifies the Biodiesel by working at a molecular level through a process called ion exchange. The LANLANG CA005DR resin literally exchanges sodium or potassium ions in the soap in the Biodiesel for hydrogen ions in the resin. This means that it breaks the soaps apart and keeps part of the soap molecule and gives up part of a hydrogen molecule, resulting in Biodiesel with extremely reduced soap levels.


The LANLANG CA005DR resin beads also act like a filter to filter out insoluable soaps, catalyst, glycerin, and water from the raw Biodiesel. This means that LANLANG CA005DR dry wash resin can help you cleanse your raw Biodiesel extremely well! By flowing Biodiesel through the resin, LANLANG CA005DR acts as an ion exchange tool to alter the soap molecules and also filters out the glycerin and other contaminants resulting in much cleaner Biodiesel. After the LANLANG CA005DR has become saturated with soap and glycerin, it can also be cleansed through a process called regeneration. This means it can be washed back out and used again several times before it's completely exhausted.

Where LANLANG CA005DR Is Used In The Biodiesel Production Process
LANLANG CA005DR ion exchange resin is used after the glycerin has been settled and removed from the Biodiesel. The resin can then be used on the Biodiesel either before or after the excess methanol has been removed (demethylation).


If soap levels in the raw Biodiesel are greater than 250 ppm, the LANLANG CA005DR resin will reach its maximum saturation of glycerin before it reaches the maximum capacity for catalyst and soap. In this case, LANLANG CA005DR should be used before demethylation. Once the resin is fully saturated with glycerin, you can utilize a methanol wash to remove the glycerin and soap from the LANLANG CA005DR. The "dirty methanol", which contains soap and glycerin, can then be reused to make Biodiesel (see below for specifics). By using the methanol wash procedure, you can restore the LANLANG CA005DR resin absorption capacity repeatedly until it's catalyst absorbing capacity is exhausted.


If soap levels in the raw Biodiesel are less than 250 PPM, the LANLANG CA005DR resin will be less likely to reach it's maximum capacity for glycerin before it reaches the maximum capacity for catalyst & soap meaning that it will typically cleanse much more raw Biodiesel before a methanol wash is needed. In this case, the LANLANG CA005DR resin can be used as a final polishing step after the Biodiesel has been demethylated.


LANLANG CA005DR Resin Life Expectancy


There are a number of factors that affect B-100 contaminant levels. These include the completion of upstream reactions, effective phase separation and feedstock quality. For a well operated system, with an average of 1000 PPM of polar (glycerin + soap) contaminants, you should expect to purify between 125 to 175 gallons of B-100 Biodiesel with each pound of LANLANG CA005DR™ resin.
