PRODUCT DESCRIPTION

DESCRIPTION

PUROLITE® PD 206 is a dry polishing media specifically formulated to remove by-products remaining from the transesterification process to produce methyl ester or B100.

PUROLITE® PD 206 is designed preferably for use in “purification” vessels installed after the phase separation and demethylation stage. PUROLITE® PD 206 can also be installed after phase separation and before the demethylation step to remove catalyst and glycerin and prevent back reactions, which form mono and di-glycerides. This media replaces magnesium silicate “wash” and may reduce or replace water wash. PUROLITE® PD 206 improves plant productivity and lowers operation costs while enabling ASTM or EN specifications for B100 to be achieved.

PUROLITE® PD 206 has a long life before exhaustion processing up to 2000 lb of B100 per pound of dry media depending on the level of impurities in the untreated biodiesel. PUROLITE® PD 206 functions both as a dehydrating (desiccant) media and as an ion exchange polishing media. As a desiccant PUROLITE® PD 206 has a high loading capacity to adsorb free glycerin and trace methanol and water. Additionally the exceptional exchange capacity removes residual catalyst, and salts that may remain after phase separation.

PUROLITE® PD 206 is flow able both in the dry form and when exhausted, making it easy to handle during installation and removal from “purification” vessels. PUROLITE® PD 206 is fully compatible for use in methyl ester and ethyl ester purification processes.

The actual life of PUROLITE® PD 206 will vary depending on process designs and operating characteristic of methyl ester feed quality. Once media is exhausted PUROLITE® PD 206, which is non-hazardous, should be disposed of in approved landfills. Check with your local waste hauler for proper disposal instructions.
