Corrugated Plate Interceptors (CPI): DESIGN PRINCIPLES
The ESI CPI is designed and engineered for oil recovery applications where energy usage and equipment costs are a determining factor. The CPI is a gravity separator where efficiency is determined by the rising velocity of the smallest particles that will be intercepted, usually greater than 50 microns. The plate pack is made of many closely spaced corrugated plates. Using Stoke’s Law, the rate of rise of the oil can be calculated. The greatest advantage of the ESI CPI is that the rising distance is usually less than one inch. This allows the oil droplets to rise and coalesce to larger droplets or sand to fall out of the flowing stream.
