The Enviro-Sep™, Corrugated Plate Interceptor (CPI), design is based on the principle of Stokes Law. CPI efficiency is determined by calculating the relationships between the flow-rate, oil and water specific gravity, temperature and oil content.
The Enviro-Sep™ CPI Separator design is based on the principle of Stokes Law. CPI efficiency is determined by calculating the
The Enviro-Sep™ Plate Separator receives produced water through the inlet (1) into the primary inlet chamber (2) with solids settling to the bottom of this compartment and free oil forming an interface above the liquid level. Separated liquids pass through a removable distribution plate (3) creating an even flow distribution across the width of the plate pack for optimum flow characteristics.
plate pack, (4) which consists of multiple corrugated plates designed to allow for oil droplet coalescence and separation. As the process flows downward through the pack, separated oil begins to agglomerate on the underside of each plate allowing for oil particle growth and their rise to a collection area at the oil water interface. A thick layer of oil forms this interface and is allowed to collect until it overflows an adjustable oil weir (5) into an oil bucket for removal.
Simultaneously, separated solids fall to the base of the pack and settle in the secondary solids chamber (6). The process water exits the bottom of the plate pack, rises upward and spills over a fixed water weir (7). On the backside of the water bucket there is a secondary oil compartment (8) which collects oil that may pass through the plate pack due to surges or upsets. Removal of this collected oil is a manual operation, opening a normally closed isolation valve. The gasketed cover (9) allows for a positive gas blanket pressure. A vent is provided for overpressure (10).
