if there is a change in density of fuel oil, do we need make any change in the alcap purifier configuration? (as in the earlier ones were we had to. Consult Alfa Laval’s Alcap separation system brochure on DirectIndustry. HFO cSt, they decided to upgrade one purifier to an Alfa Laval SA separator. To overcome this problem, Alpha Laval has developed the Alcap separator, the Ensure purifier has been fully assembled, that the bowl cover.

In the purifier mode, the EPC60 unit automatically controls the water admitted to the separator for the water seal and displacement of oil prior to sludge discharge. The Captain Nico van der Plas Jr. As Chief Engineer, write out the start up procedure for the centrifuge described in for the benefit of your staff.

Centrifugal Purifiers or Separators Theory, Working and ALCAP Principal

Hi this is Arnav Bhattacharya. Ensure sludge cycle is set to x hours.

Warm through and open heating steam to and from heaters. Special text messages indicate process parameters and alarms on the LCD display. After centrifugal separation, cleaned oil is continuously pumped away and separated sludge and water accumulate at the bowl periphery.


The total losses of sludge, oil and water during the discharge process are considerably less than other separator models due to bowl design, size, longer discharge intervals and accurate controls. The fuel cost savings alone quickly paid for the upgrade and will continue to contribute to the profitability of van der Plas fishing enterprise. However, how to adjust the throughput reducing the flow for better quality of oil should be explained.

The separator design incorporates a sludge evacuation which is absorbed by the casing and which allows the sludge volume to be discharged to a sludge tank. Canada Global Maritime Inc. The sludge accumulated in the sludge space in both a purifier and a clarifier is intermittently discharged.

Water is admitted into the bowl to soften the sludge and displace the oil in the bowl.

In case of vibration or excessive current shut down immediately and investigate. In a clarifier, the water outlet is blocked, lacap. You may also like: The bowl opens and closes very rapidly and oil loss is minimal.

Norway Puirfier Enterprises Ltd. Handling of higher viscosities available. No adjustments are necessary in the bowl, and no gravity discs are fitted. Open feed regulator to purifier and shut recirc valve.


Viscosity of a fuel is reduced by heating. In the clarifier mode, a clarifier disc is fitted instead of gravity disc. Open the catalog to page 4. This means that the conventional sludge tank under the separator can be avoided. Waqas Tariq September 25, at Water is accumulated like sludge. Change discharge from settling to service tank, and adjust feed rate to match engine consumption. Alarm functions are also provided for errors involving the EPC60 unit. How interface is created in purifier?

The CentriShoot discharge process also makes use of a patented, fixed flexing discharge slide, which apcap eliminates metal-to-metal wear. The system is operated automatically by the EPC60 control unit, except for starting the separator. The EPC60 unit provides alarm functions for low oil pressure, high intermediate tank level, and power failure.
