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.

Hi, I am not sure about the answer. AFPX High capacity solids-ejecting centrifuge Rajon Khan February 20, at 8: How flow rate of fuel affects purification? The EPC60 unit provides alarm functions for low oil pressure, high intermediate tank level, and power failure. SA separation system The SA Separation Ancillaries separation system is the most compact self-cleaning centrifugal separation system from Alfa Laval.

The fuel cost savings alone quickly paid for the upgrade and will continue to contribute to the profitability of van der Plas fishing enterprise. Reply Very explanatory article, purifker would definitely a guide to all juniors as well a refreshing note for all senior marine engineers.

Based on proven Alcap oil treatment technology, the Alfa Laval S-separator combines heavy fuel oil and lubricating oil treatment into a single separator, thanks to software that makes it possible to set the relevant parameters in the process controller. The separator bowl can be arranged as a purifier or as a clarifier.

Should be as slow as possible to maintain fuel demand.

Centrifugal Purifiers or Separators Theory, Working and ALCAP Principal

If the alcaap contains water it will build up in the bowl and start to be discharged with the clean oil. The water transducer supplies information about process conditions in the cleaned oil outlet to the EPC 50 unit.


Open the catalog to page 2. The separator bowl is fixed at the top of a spindle, which is supported by bearings and special composite springs. Flip Jork February 7, at 5: But the importance and use of pairing tube and difference between the impeller of Mitsubishi and pairing tube of Alfa laval was missing.

Special Topics For You. Set purifier oil feed to minimum.

This is a sign of reduced separation efficiency not only of water, but of solid particles too. They are difficult to remove because they are often hollow which gives them a relative density close to that of the fuel. The Alcapp and the starter box combine to form the control cabinet, which is type approved by many classification societies.

Open the catalog to page 4. Aclap operating in the purifier mode, a gravity disc must be fitted to obtain the correct interface position in the separator bowl, i.

Centrifugal Purifiers or Separators Theory, Working and ALCAP Principal | marinersgalaxy

A water transducer in the clean oil outlet measures the capacitive resistance and signals purifirr to the EPC60 control unit. Handling of higher viscosities available.

Oil paring and water pairing chamber was missed. Lifelong Obsession with all things Nerdy. This density will fall as purrifier fuel is heated up. This principle is used in Settling Tanks. It is designed to clean a wide range of fuel oils used by diesel engines in the marine and power industries.

Purifer purifier pump suction should be closed, the pump discharge valve open to the heaters, and the recirc valve open back to the purifier suction. During normal operation vital process parameters are monitored. Learn how your comment data is processed. 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 sludge is discharged to a small intermediate sludge tank. State how the problem of catalytic fines in fuel oil may be dealt with.

Canada Global Maritime Inc. Global Maritime is a marine, offshore and engineering consultancy company. Hi this is Arnav Bhattacharya. That is it can remove small quantities of water and sludge.

alcap purifiers, Forum Post, Marine Talk, Equipment Technology News resource

The discharge from the purifier should be open to the settling tank. This site uses Akismet to reduce spam. Puifier transducer in the discharge line will detect this and if this occurs after the minimum sludge cycle time, a sludge cycle will be initiated; if the water is detected before the minimum sludge cycle time, then water discharge valve will open.

General Arrangement for Purifiers on board is given in the diagram. Viscosity of a fuel is reduced by heating. If the water levels exceed the values, the process controller automatically initiates a sludge discharge. Water is admitted into the bowl to soften the sludge and displace the oil in the bowl.

But my thinking goes this way. Water is accumulated like sludge. A,cap an effort to offset fuel price increments and maintain earnings, the elder and younger van der Plas agreed in to install an HFO-ready engine and two Alfa Laval purifiers on their new meter fishing trawler.

Warm through and open heating steam to and from heaters. Purifiers are often attributed to cause sleepless nights to 4th engineers.
