    3 Separator Basics 3.1 Basic principles of separation 3.1.1 Factors influencing the separation result Separating temperatures For some types of process liquids (e.g. mineral oils) a high separating temperature will normally increase the separation capacity. The temperature influences oil viscosity and density and should be kept constant throughout the separation.
  • Page 18 3.1 Basic principles of separation 3 Separator Basics Phase proportions An increased quantity of water in a oil will influence the separating result through the optimum transporting capacity of the disc stack. An increased water content in the oil can be compensated for by reducing the throughput in order to restore the optimum separating efficiency.

  • Page 24: Design And Function

    3 Separator Basics Design and function 3.2.1 Application The MMPX 303SGP-11 is a high-speed centrifugal separator intended for marine and land applications. It is specifically designed for cleaning of mineral oils from water and solid particles (sludge). The cleaned oil is discharged continuously, while the sludge is discharged at intervals.

  • Page 25: 3.2.2 Design

    3 Separator Basics 3.2 Design and function 3.2.2 Design The MMPX 303SGP-11 separator comprises a frame consisting of the frame lower part (H), the intermediate part (E) and the frame top part (D) with a frame hood (C). The separator bowl (B) is driven by an electric motor (G) via a flat-belt power transmission (K) and bowl spindle (F).

  • Page 26: Separating Function

    3.2 Design and function 3 Separator Basics 3.2.4 Separating function Liquid flow Separation takes place in the separator bowl to which unseparated oil is fed through the inlet pipe (201). The oil is led by the distributor (T) towards the periphery of the bowl. When the unseparated oil reaches the slots of the distributor, it will rise through the channels formed by the disc stack (G) where it is evenly distributed...

    3.2 Design and function 3 Separator Basics Clarifier disc In the clarification mode, the gravity disc is replaced by a clarifier disc which seals off the water outlet. In this case no water seal is required and consequently there is no oil/water interface in the bowl.
  • Page 29 3 Separator Basics 3.2 Design and function Bowl opening The key event to start a sludge discharge is the downward movement of the operating slide. This is accomplished by supply of opening water (372) to the discharge mechanism. Water is drained off through nozzles (Y) in the bowl body.

  • Page 35: Start After A Service

    4 Operating Instructions 4.1 Operating routine The best separation results are obtained by using a gravity disc with as large a hole diameter as possible, which will not cause a broken water seal in the bowl or an emulsification in the water outlet. The presence of salt water in the oil may demand the use of a gravity disc with bigger hole than indicated in the nomogram.
