Maximizes equipment lifetime and increase availability
Our comprehensive EDITUBE® Wet Electrostatic Precipitator (WESP) inspection service maximizes equipment lifetime and increases availability. Our operational and technology expertise assists in maintaining a high level of performance and safety.
Decreased maintenance costs
Minimized power waste
A WESP is traditionally the last piece of gas cleaning equipment before the process gas enters the acid plant or stack. Performance losses in this section can have a significant influence on acid product quality, plant availability or maintenance costs as passing particles will lead to impurities in the sulfuric acid, form plant deposits or result in emissions into the atmosphere.
Ensuring high performance of the WESP is therefore essential and requires in-depth knowledge of the equipment with regards to process, mechanical and electrical aspects. Due to long service intervals, it is almost impossible to develop and maintain this expertise with site personnel. Failing to provide the appropriate equipment care can have a negative influence over time and lead to:
Reduced removal efficiency
High corrective maintenance costs and decreased availability
The Metso Outotec EDITUBE WESP inspection scope combines three areas of expertise into one comprehensive service package, ensuring the maximized performance of EDITUBE throughout the lifetime.
The inspection consists of reviewing the current WESP operation, inspections of the mechanical and electrical conditions including:
Identification of key performance parameters from DCS and the control system
Evaluation of key operational data and report on recommendations with regards to T/R unit operating parameters
Inspection of the mechanical equipment condition
Inspection of electrical equipment
Verification of required/available spare parts
These activities are performed by experienced Outotec service personnel while maintaining the highest standards in work safety.
A service report is compiled for each inspection which summarizes the overall condition of EDITUBE and provides recommendations for improving operations, alignment and follow-up maintenance, which may include repairs or replacements. Possible upgrades and modernizations are recommended and the spare part status is verified.
The regular performance of the WESP inspection supports a systematical approach to plant maintenance and provides benefits for the plant operation such as:
