Plant Audit - Water Chemistry and Corrosion Control
Two-to-three day review of water and steam chemistry, operation, and maintenance of the steam generating plant aimed at prevention/reduction of cycle component corrosion and scale and deposit formation.  Results of the audit are recommendations for optimization of the plant procedures and practices.
Note:  The Condition Assessment Audit can be performed during the same plant visit.  
Background
With the increase of unit sizes, stresses, and heat fluxes, equipment aging, unit cycling, and the high cost of replacement power and steam, corrosion protection of the steam cycle components during operation and layup and the control of water and steam chemistry are of critical importance.
Objectives
Prevention/reduction of cycle component corrosion and the resulting forced outages and maintenance cost.
Operation at the maximum thermodynamic efficiency (minimum heat rate) and generating capacity.
Audit Experience
Each of the over fifty audits performed resulted in one or more of the following achievements:
improvement of communication between management, chemists, operators, and maintenance
reduction of scale and deposit buildup
improvement of efficiency and generating capacity
reduction of corrosion
prevention of potentially catastrophic failures
faster startups
improvement of operation
better layup practices
improvement of sampling and instrumentation
better recordkeeping
improvement of the makeup and condensate polisher performance
reduction of cost of water treatment chemicals.
AGENDA FOR PLANT AUDIT
Before the plant visit, a Jonas, Inc. Water Treatment Questionnaire and related information is complied and reviewed.
