ALCAP PURIFIER PDF

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.

The company provides highly specialized professional engineering services to the marine and offshore industries assisting during execution of complex projects. In a clarifier, the water outlet is blocked, i.

Centrifugal Purifiers or Separators Theory, Working and ALCAP Principal

The discharge from the purifier should be open to the settling tank. 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. The feed regulating valve alcsp the purifier should be set to zero. That is it can remove small quantities of water and sludge.

The EPC60 puriffier provides alarm functions for low oil pressure, high intermediate tank level, and power failure. When operating in the purifier mode, a gravity disc must be fitted to obtain the correct interface position in the separator bowl, i.

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. Handling of higher viscosities available. After centrifugal separation, cleaned oil is continuously pumped away and separated sludge and water accumulate at the bowl periphery. The separator bowl is fixed at the top of a spindle, which is supported by bearings and special composite springs.

The separator design incorporates a sludge evacuation which is absorbed by the casing and which allows the sludge volume to be purififr to a sludge tank.

The sludge is discharged to a small intermediate sludge tank.

Manually set gravity discs have replaced the more refined Alcap technology in the separator bowl. Lifelong Obsession with all things Nerdy. They cause abrasive wear in fuel pumps, injectors, liners and piston purifidr. Water is admitted into the bowl to soften the sludge and displace the oil in the bowl.

The system is operated automatically by the EPC60 control unit, except for starting purifirr separator. Other factors that assist separation are: Upgrading an Alfa Laval purifier originally installed onboard to an Alfa Laval SA separator system drastically reduced fuel costs.

The 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. The lower the viscosity the lower the drag force on sludge particles.

Special text messages indicate process parameters and alarms on the LCD display. When water is detected in the cleaned oil, the transducer sends a signal to the EPC 50 process controller. Infact at one point in time Eureka Forbes use to be seen as a training ground for budding sales purofier, Best non electric alcwp purifier in India in AFPX Purrifier capacity solids-ejecting centrifuge This means keeping the purification temp as high as possible and the throughput as low as possible.

Their membership includes ship equipment manufacturers, fishing equipment suppliers and the aqua culture industry. Reply Very explanatory article, which would definitely a guide to all juniors as puriffier a refreshing note for all senior marine engineers. Hello Srinivas, It is because of the pressure difference of water. The EPC60 control system masterminds the operation of the separation system and allows the monitoring of control and alarm functions. They are difficult to remove because they are often hollow which gives them a relative density close to that of the fuel.

Clear text messages, alcaap in several languages, indicate process parameters and alarms on the LCD display. Oil is fed into the high speed rotating bowl which basically operates as a clarifier, but water and solids are separated and are thrown to the outside of the bowl by centrifugal force.
