Marine Fuel Oil Separator

Product Description

Marine Fuel Oil Separator

 

1. Application

 

    The marine fuel oil separator is 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.
The separator handles the following types of lubricating oils and low viscosity fuel oils:
    Distillate  (viscosity 1.5-5.5 cSt/40℃)
    Marine diesel oil  (viscosity l3 cSt/40℃)
    Intermediate fuel oil and heavy fuel oil  (viscosity 30-380 cSt/50℃)
    Lubricating oil of R & O type, detergent or steam turbine.
    The separator can be operated either as a purifier or as a clarifier. When operated as a purifier the separator discharges the separated water continuously.
    When the oil contains only small amounts of water the separator is operated as a clarifier, discharging the water together with the solid particles.
    The separator has to be installed together with devices for control of its operation.
 

2. Separating Function

 

(1) Liquid flow
    Separation takes place in the separator bowl to which unseparated oil is fed through the inlet pipe. The oil is led by the distributor 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 where it is evenly distributed into the disc stack.
    The oil is continuously separated from water and sludge as it will flow towards the center of the bowl. When the cleaned oil leaves the disc stack it rises upwards and enters the paring chamber. From there it is pumped by the paring disc and leaves the bowl through the outlet.
    Separated sludge and water move towards the bowl periphery. In purification separated water rises along the outside of the disc stack, passes from the top disc channels over the edge of the gravity disc and leaves the bowl into the common sludge and water outlet of the separator.
    Heavier impurities are collected in the sludge space outside the disc stack and are discharged at intervals
through the sludge ports.
(2) Water seal in purification
    To prevent the oil from passing the outer edge of the top disc and escaping through the water outlet, a water seal must be provided in the bowl. This is done by filling the bowl with water through the water inlet, before unseparated oil is supplied. When oil feed is turned on the oil will force the water towards the bowl periphery and an interface is formed between the water and the oil. The position of the interface is determined by the size of
gravity disc.
(3) Displacement of oil
    To avoid oil losses at sludge discharge, displacement water is fed to the bowl. Prior to a discharge the oil feed is stopped and displacement water added through the water inlet. This water changes the balance in the bowl and the interface moves inwards to a new position, increasing the water volume a new position, increasing the water volume in the sludge space. When the sludge discharge takes place sludge and water alone are discharged.
    Sludge discharge occurs while the displacement water is still flowing. A new water seal will therefore establish immediately afterwards. The oil feed is then turned on again.
(4) Gravity disc
    In the purification mode, the position of the interface can be adjusted by replacing the gravity disc for one of a larger or smaller size. A gravity disc of a larger size will move the interface towards the bowl periphery, whereas a  disc of a smaller size will place it closer to the bowl centre.
    The sizes of the gravity discs are normally stamped on the discs.
(5) 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. The clarifier disc is an optional disc with a hole diameter of 40 mm. This disc is not shown in the nomograms.
