Abstract
A separation assembly is generally described that can chemically treat condensate material in a fluid stream. One particular example of a separation assembly is a crankcase filtration assembly used in engine oil filtration and that includes an additive material disposed within the crankcase filtration assembly. The additive material chemically treats condensate material of blow-by fluids received by the crankcase filtration assembly when a condition is present in the condensate material. For example, the crankcase filtration assembly provides a unique structure with a chemically treated component that can reduce an acidic condition in condensate material received by the crankcase filtration assembly, and even more generally may extend engine oil life.
