KRZ41 is a specialty polymer media, which is effectively formulated for removing by-products remaining after transesterification to produce biodiesel.
KRZ41 is designed for reducing the acid value in biodiesel processing. 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. KRZ41 improves plant productivity and lowers operation costs.

KRZ41 has a long life before exhaustion. This life is dependent upon the point of installation in the biodiesel process. Additionally the exceptional exchange capacity removes residual catalyst, and salts that remains after phase separation.
The actual life of KRZ41 will vary depending on process designs and operating characteristic of methyl ester feed quality.
Once KRZ41 is ready for disposal; it should be disposed of in approved landfills or facilities according to local regulations.
