High Melt Point Esters are Fatty Acid Methyl Esters with a melt point above ambient.
They are typically seen in winter as either suspended flakes in the biodiesel, or white/yellow cream at the bottom of drums.
The Whole Batch Demeth (WBD) processing method may produce more HMPEs than traditional methods, though this is unconfirmed. There is some speculation that this may be because the yeild is higher using this technique, and that the level of HMPEs could be reduced by doing a cold Water Prewash
