Abstract: This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by applying non-condensable media to create density differences and then using a mechanical device to separate the solids from the liquids based on the density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.

Abstract: A mixed fluid separator apparatus includes an overload protection chamber that prevents a large and sudden influx of oil from fouling a coalescing separator. To prevent sudden influx of a large concentration of oil from overwhelming the coalescing separator, a separate overload protection chamber is connected to a main coalescing separator apparatus. The overload protection chamber includes a water drain (majority water with some oil) to the main coalescing separator apparatus and an oil overflow (majority oil with some water) to drain excess oil when necessary to prevent overfilling of the coalescing separator apparatus. The overload protection chamber functions to rapidly separate and remove heavy concentrations of oil, protecting the main coalescing separator apparatus.
