EscrowUnlt © AP6.0Produce cleaner bio-diesel consistently. With Purolite PD 206 cleaner bio-diesel fuels can be produced at lower cost and with much less waste. And Purolite PD 206 when used in final purification helps you meet USA and European standards. That means fuel that can be marketed worldwide, even for demanding high-performance applications. Best of all, Purolite PD 206 includes Purolite technical support. This means answers from experts that can put more efficiency and product quality into your bio-diesel plant. PUROLITE® PD206 is a dry polishing media specifically formulated for removing by-products remaining after transesterification to produce biodiesel. PUROLITE® PD206 is designed for use in “purification†vessels installed after phase separation. Point of use can either be before demethylation to remove catalyst and glycerin and prevent back reactions or after demethylation as a “final†polishing step.This media may replace magnesium silicate “wash†and water wash. PUROLITE® PD206 improves plant productivity and lowers operation costs while enabling ASTM or EN specifications for B100 to be achieved. PUROLITE® PD206 has a long life before exhaustion. This life is dependent upon the point of installation in the biodiesel process and on the level of impurities in the untreated biodiesel. PUROLITE® PD206 functions both as a dehydrating (desiccant) media and as an ion exchange polishing media. As a desiccant PUROLITE® PD206 has a high loading capacity to absorb free glycerin. Trace methanol and water although being absorbed to a limited degree should be removed by stripping in the demethylation column. Additionally the exceptional exchange capacity removes residual catalyst, and salts that remains after phase separation. PUROLITE® PD206 is flowable both in the dry form and when exhausted, making it easy to handle during installation and removal from “purification†vessels. PUROLITE® PD206 is fully compatible for use in methyl ester and ethyl ester purification processes. PUROLITE® PD206 can be washed with methanol on site several time to maintain it's ability to remove glycerin. However it must be ionically regenerated to maintain the ability to remove trace catalyst and soaps. Consult your Purolite representative for availability and details. Call for more information (***)-517-4707 Purolite® PD206 is a dry ion exchange resin that functions as a combined desiccant and ion exchange media it is specially formulated to enable maximum removal of free glycerin as well as catalyst, soaps and salts from crude biodiesel. Purolite® PD206 is designed for use in “purification†vessels primarily installed after phase separation and before or after demethylation. What are the benefits of using Purolite® PD 206? Purolite® PD206 is a cost effective method of purifying biodiesel removing glycerin and ionic contaminants. This technology provides a simple, low energy process to eliminate water wash steps and other inorganic labor intensive processes. Higher biodiesel production can be obtained by reducing processing time compared to alternate purification methods. Purolite® PD206 will reduce waste disposal of both liquid and solids. Since Purolite® PD206 may be regenerated, returning it to original performance; this product can be reused for many years before being disposed. Dry Purolite® PD206 should be loaded into two or three tall narrow purification columns (“leadâ€, “lag†and/or “standbyâ€) operated in series. The lead vessel does the bulk of the glycerin removal and the second or lag vessel polishes trace glycerin leaking from the lead vessel. Recommended vessel configuration is for the height to be at least 3 times the diameter and that resin be filled to 50% of the vessel height as the resin will swell to nearly twice its original volume. Crude biodiesel flows through the lead and lag vessels to maximize media loading on the lead column optimizing operating cost and labor. When free glycerin leaving the lag vessel exceeds 0.01%, the standby vessel is put on-line in the lag position, the original lag is now in the lead position and the original lead bed is now removed from service. Media in this off-line vessel is either replaced if operated after demethylation or flushed with methanol to remove glycerin if positioned before demethylation then placed in standby (or in the lag position if only two vessels are used).
