The continuous build-up of coke on the inner walls of fired heaters and heat exchange surfaces in oil refineries and bitumen upgraders commonly leads to reduced energy efficiency and periodic shutdown of the affected process unit.
Decoking Descaling Technology Inc (DDT) has developed the most advanced system for off-line decoking of fired heaters. DDT’s technology can remove the hardest coke and scale that forms in commercial fired heaters. We are the company that refiners turn to when the competition runs into situations that demand superior technology to remove the toughest coke.
The DDT process removes coke build-up from heater tubes in a series of highly-controlled incremental cleaning runs. Because the DDT process is much more effective than steam-air decoking, chemical cleaning, or any other mechanical cleaning method, our customers attain all the economical benefits of an increased run length, longer tube life, and a lower fuel usage.
DDT’s Bi-Directional Pigg® Control Method facilitates the cleaning of heaters which incorporate reducers and changing pipe diameters, without having to make any onsite modification. This technology allows our operators to concentrate on the most contaminated section of a heater thereby further optimizing the cleaning procedure.
