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.

Open operating water and set bowl operating water to close. Water is continuously discharged from the bowl.
Reply In alfalaval purifiers ,opening water and closing water are connected through same pipe from the solenoid water block, how do they function during alcxp and closing of discharge slide Reply Hello Srinivas, It is because of the pressure difference of water.
Hello Srinivas, It is because of the pressure difference of water. The system operates on the Alfap principle. This means that the conventional sludge tank under the separator can be avoided. Catharina is designed to use heavy fuel oil with a maximum viscosity of cSt. The separator is driven by an electric motor via a friction clutch and belt. Fast payback Comparable fishing trawlers typically use marine gas oil as fuel.
Centrifugal Purifiers or Separators Theory, Working and ALCAP Principal
Wishes to be this Generations’ Yevgeny Zamyatin. Oil is fed into the high speed rotating bowl which basically operates as a clarifier, but water and solids are purifiee and are thrown to the outside of the bowl by centrifugal force.
This site uses Akismet to reduce spam. Canada Global Maritime Inc. Warm through and open heating steam to and from heaters.
The purifier pump suction should be closed, the pump discharge valve open to the heaters, and the recirc valve open back to the purifier suction. For generations, the van der Plas family fishing business relied on marine gas oil to power its trawlers around the North Sea. But the importance and use of pairing tube and difference between the impeller of Mitsubishi and pairing tube of Alfa laval was missing.
Reply can i ask how thus the flow control disc work Reply But the importance and use of pairing tube and difference between the impeller of Mitsubishi and pairing tube of Alfa laval was missing. Likes to dabble in Poetry, Literature, Art and Cinema. Other factors that assist separation are: Martech is an engineering consulting company incorporated in British Columbia, Canada.
Open the catalog to page 4. ViscoLine Monotube Unit A water transducer in the clean oil outlet measures the capacitive resistance and signals changes to the EPC60 control unit. A purifier separates sludge and water from the oil. Learn how your comment data is processed. AFPX High capacity solids-ejecting centrifuge 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.
Should be as slow as possible to maintain fuel demand.
ALCAP High density Purifier used Onboard Ship
The water transducer supplies information about process conditions in the cleaned oil outlet to the EPC 50 unit. Open the catalog to page 2.
On the other hand, heavy fuel oil must undergo the process of cleaning purifoer fuel oil to be of the correct viscosity before being injected into the engine. No adjustments are necessary in the bowl, and no gravity discs are fitted.
Alcap separation system – Alfa Laval – PDF Catalogs | Technical Documentation | Brochure
Start the purifier watching the ammeter which should fallback as the purifier speed increases. Newbuilding Orders for Daewoo. In alfalaval purifiers ,opening water and closing water are connected through same pipe from the solenoid water puriffier, how do they function during opening and closing of discharge slide.
The result is a separator with the same high performance, but one that does not automatically compensate for process fluctuations. In case of vibration or excessive current shut down immediately and investigate. Depending on the actual process conditions, the EPC 50 process controller selects the operating mode.
The sludge is discharged to a small intermediate sludge tank.
Very explanatory article, which would definitely a guide to all juniors as well a refreshing note for all senior marine engineers.
