DECOKING & DESCALLING SERVICES

Kanooz provides comprehensive Decoking and Descaling services for fired heater tubes and pipelines utilizing specially designed studded pigs and Decoking Machineries. Mechanical Decoking by pigging method has proven to be the most effective, safer, and environmentally friendly method for decoking fired heaters.

Decoking Process:

The decoking process involves a closed-loop recirculation of pig driving medium for the cleaning operation. Metal studs protruding from the poly foam pig scrape and remove coke deposits while passing through the tube. A controlled amount of water flows around the pig and past the cleaning heads, flushing loose coke deposits ahead of the moving pig and collecting them in a tank.

Decoking Equipment:

The decoking/descaling process employs various types and sizes of pigging materials and tool configurations depending on the type and hardness of coke/scale. The equipment used to drive the pig through the tubes/pipes is custom-built to suit the specific requirements of the operation.

Kanooz's state-of-the-art DOUBLE PUMPER decoking machines represent the pinnacle of efficiency in decoking operations. These machines have the capability to decoke two passes simultaneously, leveraging 2000-gallon pumps. This innovative design significantly reduces decoking time compared to conventional decoking machines.

Benefits of Decoking by Pigging

  • Complete Removal of Furnace Coke: Decoking by pigging ensures thorough removal of coke deposits from furnace tubes, leaving them clean and free of obstructions.
  • Safety and Environmental Friendliness: This method is safer and more environmentally friendly compared to conventional methods like steam-air decoking. It reduces the risk of accidents and minimizes environmental impact.
  • Simultaneous Maintenance Activities: Decoking by pigging allows for concurrent maintenance activities such as refractory works, burner inspection, and tube inspection. This simultaneous approach reduces overall downtime and maximizes operational efficiency.

Decoking by pigging stands out as a reliable, safe, and efficient method for maintaining furnace integrity and prolonging equipment lifespan.
