Optional Coalescer Pack Equipped IGF

Optional Coalescer Pack Equipped IGF

To aid the separation process the IGF is equipped with coalescer packs and diverter plates. Usually, IGF vessels are internally broken down into compartments with each compartments consisting of eductors, coalecser pack and diverter plate. The IGF is also equipped with a deflector plate and an oil bucket. See IGF internal layout draw­ing for further visual clarification.

Diverter Plates:

These plates seperate the IGF compartments. Each separation compartment consists of a pair of eductors and a coalescer pack. The diverter plates not only separate the compartments but also allow the fluid to flow in a predetermined manner. This increases the retention time which aides the proper removal of the free oil particles.

Eductors:

The eductors are static jet pumps which uses water as a motive force to induce gas bubbles into the oily water. The bubbles assist the oil particles to coalesce to form bigger particle which float to the surface to form an oil film.

Coalescer Pack:

Each compartment has a coalescer pack to further assist the formation of larger oil particles. The pack achieves this by increasing the contact surface area of the fluid thus allowing more free oil particles to come together. There are several types of coalescer packs. The plate type is used for this project.

Deflector Plate:

The deflector plate is installed in the vessel with an inclination to force the oil film into the oil bucket. Since oil will float on water restricting the oil film to a portion will create a thicker oil film which can be skimmed into the oil bucket.
