Divergan® F (PVPP) absorbs the haze forming polyphenols which eliminates that fraction from the Protein/Tannoid Complex, the major cause of non-biological post-filtration turbidity.
Optimal addition would be after the aging vessel before the filter, however, it can also be added to the aging vessel provided a sufficient sedimentation period is assured. Optimal dosage temperature is 32° F or below with good dispersion and a minimum contact time of 4 minutes. PVPP is dusty and typically requires a 2 hour hydration period prior to use.
Typical Dosage Rate: 3 - 6 lbs/100 bbls
