Preventive Maintenance starts with an in-house review of oxidizer and process diagram followed by audit of system’s operation. Customers receive a detailed report with recommendations for improving performance, reliability, and safety, upon completion of the inspection service.
S&SE PM service is broken down into the following categories but it may vary based on equipment and model:
Internal & External Mechanical Inspection
External and Internal Mechanical Inspections include but are not limited to: Reactor Chambers, Access Doors, Compressed Air Train, Valves, Media or Catalyst, Insulation, Fan(s), Ductwork and Exhaust Stack, Fuel Train, Burner(s), Expansion Joint(s), Control Panels, Dampers, Collection Plenum, and Flame Arrestor.
Inspection and Component Tests include but are not limited to: Thermocouples, Switches, Actuators, Variable Frequency Drive (VFD), Motors, Starters, Burner Control System, Temperature and Pressure Controllers, Chart Recorder, Lights, Relays, Timers, Emergency Stops, Disconnects, Man Machine Interface (MMI) and Modem
Process Control Analysis
Process Control Analysis includes but is not limited to: System Startup Cycle, Online Conditions, Safety Shutdowns, Alarms, Pressure Control Loops, Valve Cycling, Temperature Profile, Burner Tuning, and Airflow Verification.
Check Critical Parameters
As your oxidizer system get old, you should check critical parameters of your system like TER (thermal energy recovery). After 5 years operation, an average sized RTO designed for %95 TER may slipped to %93 TER. It may reluctant even in the maintenance department. Running a full operating at %93 TER verses %95 TER could add more operation cost.
Evaluate the Operating Cost
Typically, peak of VOC (Volatile Organic Compound) determines your oxidizer design, but average VOC load determine your operation cost. Evaluating and learning what your estimated operating cost can help determine steps to take to reduce the coast associated with operation of thermal oxidizers.
Operating an oxidizer is a long term commitment. In addition to operational data logs, EPA & local environmental agencies require accurate documentation of oxidizer service & maintenance records. Part of that may include having the necessary spare parts on hand for your oxidizer system and prevent down time as well as compliance issues.
Additional services include but not limited to: Emission Monitoring of Process, Destruction Efficiency Checks, Onsite Analysis, Laboratory Analysis, Catalyst Activity Testing, System Inlet Balancing. If operation systems/equipment was affected by environmental requirements, appropriate documentation needs to be recorded. The owner/permit holders is required to show the maintenance document to air quality agent in a manner that provides assurance of continued and ongoing compliance.
