Filter Monitor Qualifications

Element Date Comment

Facet FG2XX-6 April 2011 New SS centre tube + media change

Faudi M2-770-6 Sept 2011 New water absorbent media

Velcon CDF 2XX-P Sept 2011 AL centre tube + media change

•1583 6th ed Filter Monitor Qualifications

No 6” elements currently qualified – expected

late 2012 – change when available

All 2” filter monitor vessels to have 6th

edition elements fitted by Dec 2012


10


• Filter monitor Operation

• Element change out - 1 year (Manufacturer

recommendation) or 22 psi

• Not for use in FSII fuel

• Flow rate should be optimised (avoid repeated low

flow operations)

• Consider use of blanks if necessary

• Monitor differential pressure and investigate severe

changes in differential Pressure


11


Differential Pressure Correction


12


• Differential Pressure Correction

To ensure that the filtration system is not

exposed to conditions outside of the

elements qualified dirt/water removal

performance envelope.

• Can still be done manually

• Option for automatic systems


13


• Differential Pressure Sensing and correction


14


• Automatic dP correction

Rely on piston type dP gauge or electronic

transducers

Different correction factors used between suppliers

(challenge for when different supplier used)

Different correction technologies used FWS v Filter

monitors

Considerations for data management!


15


Differential Pressure Switches


16


• Differential pressure switches

• To ensure elements are not

subjected to elevated pressure

• May be Mandated to fit some

type of device


17


• Differential pressure switch

Piston differential pressure gauges used to provide

dP - In-line pressure devices are an option but will

require further processing

Operational pressure to be set at a pre-set level

Note: Industry investigating options of water probes

to provide additional information


18


• Differential pressure -Summary

Better education required on differential pressure

measurement, correction and implication for operation

Options for new technology to help

New technology (switches) – likely to be mandated

Challenge: What do you do in the event of a lock out?

Do we have supervisor intervention?


19


Similarity & Compliance


20

EI 1582 Similarity

Why

To ensure vessels always meet the

performance requirements of EI 1581

To minimize the number of full scale tests

required.

To allow interchangeability between suppliers


21

• 2nd ed published Dec 2011

• Mandates use of standard

sheet


Similarity & Compliance


22

EI 1582 Similarity

Challenges

• Vessels are in service for a long period (up to

40 years)

• Specifications change to meet changing needs

and vessel requirements change (API

withdrawal)

• Interchangeability of elements (different

manufacturers) is required

• Similarity becomes an issue of compliance

(Qualification v in-service) e.g. positive water drain


23

Similarity - Considerations

•Orientation – Vertical or Horizontal

•Flow Pattern

•Coalescer & Separator -the same

•Element spacing

•Element types

•Flow per unit area

•Separator Entrance/Face velocity

•Element/Vessel Ratio’s

•Void Volume

•Void volume ratio

•Sump volume


24

API/EI 1581 5th Edition / API/EI 1596 1st Edition

Vessel Mechanical Compliance Assessment

• Carbon steel vessels to be internally coated with light-

coloured epoxy coating

• Vertical vessels – lid fall prevention device

• Anti-vibration plate (spider) – the free ends of all

cartridges greater than 46 cm (18 in.) long shall be

stabilised to minimise vibration.

• Thermal (pressure) relief valve

• Automatic air eliminator


25

API/EI 1581 5th Edition / API/EI 1596 1st Edition

Vessel Mechanical Compliance Assessment

• Direct reading pressure differential gauge with

stainless steel sensing lines

• Length to diameter ratio for vertical vessels

• Clean-out/inspections connection

• Work platform, access steps and handrails

• Electrical continuity – all metal items inside the vessel

shall be in electrical contact with each other and the

vessel body. The resistance between any two items

shall be less than 10 ohms.


26

Similarity & Compliance summary

A FWS system can meet the performance requirement

of EI 1581 5th edition but may not meet all the

mechanical requirements – The system is said to

meet the performance requirements of EI 1581 5th

edition

It is only possible in a pre-1581 5th edition a vessel for

the FWS to meet the performance requirements of

5th edition if the vessel as positive water drainage.

(Positive water drainage has been a requirement for

new 1581 FWS vessels since 1989.)

Non conformance to be managed (Not evergreen)


27


•Similarity Sheets

• Request from the filter supplier one for each vessel –

store locally with Vessel operation data

• Manufacturer to provide similarity sheet – End user to

check to ensure compliance

• There may be compromises in vessel performance

• Non compliance to be managed– NOT evergreen
