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.

This density will fall puriifer the fuel is heated up. This means that the conventional sludge tank under the separator can be avoided. The bowl opens and closes very rapidly and oil loss is minimal. Martech is an engineering consulting company incorporated in British Columbia, Canada. Let us know in the Comments!

Viscosity of a fuel is reduced by heating. A patented paring tube adapts itself to remove the water from the bowl and a paring disc pumps away the cleaned oil. The water transducer supplies information about process conditions in the cleaned oil outlet to the EPC 50 unit. However, after two full years of operation, the father-and-son team decided to explore the possibilities of further increasing fuel cost savings.

Ensure sludge cycle is set to x hours. In the clarifier mode, a clarifier disc is fitted instead of gravity disc. How interface is created in purifier? This reduces chances of foaming. Fast payback Comparable fishing trawlers typically use marine gas oil as fuel. The CentriShoot discharge process also makes use of a patented, fixed flexing discharge slide, which completely eliminates metal-to-metal wear. Start the purifier watching the ammeter which should fallback as the purifier speed increases.

The Online Industrial Exhibition. S-separator The Alfa Laval S-separator is the principle component of a range of high efficiency heavy fuel oil separation systems. 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.

The lower the viscosity the lower the drag force on sludge particles. Likes to dabble in Poetry, Literature, Art and Cinema. Hi, I am not sure about the answer. Very explanatory article, which would definitely a guide to all juniors as well a refreshing note for all senior marine engineers. In alfalaval purifiers ,opening water and closing water are connected through same pipe from the solenoid water block, how do they function during opening and closing of discharge slide.

Open the catalog to page 3. When water is detected in the cleaned oil, the transducer sends slcap signal to the EPC 50 process controller.

Viscosity of the oil: After centrifugal separation, a,cap oil is continuously pumped away and separated sludge and water accumulate at the bowl periphery. Depending on the actual process conditions, the EPC 50 process controller selects the operating mode.

Ensure the purifier does not vibrate. Kranthi Kiran September 19, at 9: This is a sign of reduced separation efficiency not only of water, but of solid particles too.


This makes it possible to operate under optimal conditions Their membership includes ship equipment manufacturers, fishing equipment suppliers and the aqua culture industry. Global Maritime is a marine, offshore and engineering consultancy company.

State how the problem of catalytic fines in fuel oil may be dealt with. Continue to recirc fuel until purification temperature is reached.

Your email address will not be published. In addition, functions are available for vibration alarm when the optional vibration switch is fitted.

Waqas Tariq September 25, at The separator bowl can be arranged as a purifier or as a clarifier. Change discharge from settling to service tank, and adjust feed rate to match engine consumption. This does not require any change with sg of F. In case of vibration or excessive current shut down immediately and investigate. Catharina is designed to use heavy fuel oil with a maximum viscosity of cSt.

When a transducer in the oil discharge line detects water the bowl is opened and the sludge and water discharged. AFPX High capacity solids-ejecting centrifuge The fuel cost savings alone quickly paid for the upgrade and will continue to contribute to the profitability purifler van der Plas fishing enterprise. Alarm functions are also provided for errors involving the EPC60 unit.
