Alfa Laval Compabloc Plate Heat Exchanger CP50

Supervision of Key Process Parameters

Record the temperature of the heat exchanger

Record the pressure drop across the heat exchanger

Is there any contamination of media observed?

If contamination is observed, describe the analysis for possible internal leakage

Is the pressure drop variation within acceptable limits?

Is cleaning of the heat exchanger required to remove fouling?

Ensure chemical cleaning is performed by authorized and qualified personnel.

Take all necessary protection and precautions for health, safety, and environment regarding chemicals.

Select the type of deposit and corresponding cleaning agent

Ensure compatibility of cleaning agents with materials of construction such as metal and gaskets.

Follow complete cleaning protocol including agent, concentration, temperature, and time.

Check suitability of cleaning protocol with materials of the Compabloc.

Is reverse flow direction (back flushing mode) used for optimal results?

Ensure inspection or heavy mechanical cleaning is required before dismantling.

Record baffle positions before dismantling for correct reassembly.

Pull out the ladder formed by uprights and baffle plates.

Remove triangular PTFE cord gaskets from longitudinal girder lining.

Remove the complete baffle cage.

Clean the triangular groove of the longitudinal girder lining and remove grease.

Dismantling Procedure for Panels

Progressively loosen the nuts one girder after the other

Loosen bottom nuts one panel after the other

Do not unscrew stud bolts or nuts for girder assembly

Remove panels starting with the highest weight

Use welded or screwed lifting lugs to lift panels safely

Clean gasket seating surface thoroughly without scratching

Inspect external elements of the heat exchanger

Check for issues on external elements

Inspect all welds for cracks, defects, and corrosion

Check painting for local absence of coating and blistering

Proceed with internal examination?

Estimate condition of internal elements

Check for issues on internal elements
