consists
is a vertical pressure vessel designed to handle the mixture of oil and gas, and water, at all stages of the treatment process to ensure low oil in the water before being discharged or re-injected. This new generation of CFU is a high performance single device. Its technology is based on principles floating through special internal parts which create small gas bubbles that attach to oil droplets and contribute to the separation process. The flotation process is maintained by the evolution of dissolved gases and / or additional gas injected into the water feeder. Oil droplets and gas bubbles are mixed together, and because of the low density of this mixture, oil and gas are easily separated in the container. The special design of the internal parts of the container allows this process is repeated in several steps, whose number depends on the application where the technology will be used. Compared with existing technology this new unit can handle many more small droplets of oil, even up to one micron can be removed.
