Understand the relationship between circulation, pressure drop and wash solution condition.

Circulation flow indicates whether liquid is reaching the contact section as intended. Pressure drop can help identify changes in the gas path, although the meaning of a change depends on the equipment arrangement and operating flow.

Solution condition may be assessed with suitable measurements and sampling procedures. Dosing, blowdown and make-up water should follow the reviewed process requirements rather than an assumed universal setting.

Operators also need an inspection schedule for spray distribution, accessible packing areas and mist separation components. Inspection and maintenance must follow site procedures for isolation, chemical handling and safe access.
