Kanooz offers comprehensive Decoking and Descaling services for fired heater tubes and pipelines using specially designed studded pigs and Decoking Machineries. The mechanical Decoking by pigging method proved to be the most effective, safer and environmentally friendly method for decoking fired heaters.
Decoking Process: The decoking process employs a closed loop recirculation of pig driving medium for the cleaning operation. The protruding metal studs on the poly foam pig will scrape and remove the coke deposits while passing through the tube. The controlled amount of water flows around the pig and past the cleaning heads thereby flushing the loose coke deposits ahead of the moving pig and to bring into the collection tank.
Decoking Equipment: The decoking/descaling employs different type & size of pigging materials and tool configurations depending upon the type and hardness of coke/scale. The equipment that drives the pig through the tubes/pipes is basically custom built to serve the purpose.
Kanooz's state of the art DOUBLE PUMPER decoking machines are capable of decoking two passes simultaneously using 2000 gallon pumps and minimize the decoking time drastically as compared to conventional decoking machines.
Benefits: Decoking by pigging guarantees complete removal of the furnace coke unlike steam-air decoking. The method is much safer and environmentally friendly as compared to conventional methods and allows maintenance activities such as refractory works, burner inspection, tube inspection, etc. simultaneously that reduce the overall down time.
DECOKING & PIGGING EQUIPMENT
Kanooz's decoking units are self-contained and built on mobile trailers to facilitate faster mobilization and proper reach/access to the work location without the assistance of crane/handling. The semi-automated unit has latest pressure-flow instrumentations that allow the operators to control the direction, speed, location of the pig etc. and thus to eliminate stuck pig scenario and monitor the movements through the desktop monitor.
Inline Inspection by Intelligent / Smart Pigging: Teamed up with strategic partners, Kanooz offers intelligent/smart pigging services for fired heater tubes and pipeline inline inspection etc. And carried out several inspection tasks through long form /short form contracts.
