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 processing method seems to produce more HMPEs than traditional methods. There is some speculation that this is because the yeild is higher using this technique, and that the level of HMPEs may be reduced by doing a cold Water Prewash
