An Overview Of Decoking Descaling Technology Inc

By Merv Carlson


Being founded in the fall 1991, Decoking Descaling Technology Inc is widely known to be the pioneer to do progressive pigging of fired heaters in oil refineries. DDT is the pioneer in this advanced technology and currently holds seventeen patents all around the world.

The invention of decoking descaling technology has made DDT become a reliable company which refiners turn to when they need their tubes and other industrial applications to be free from cokes and scales. DDT has customers all around the world. They have served many clients inside and outside Canada. The total countries they have done the job is 26 with total customer satisfaction.

D.D.T. is operating world wide direct or through assigned agents with 29 warehousing locations in eight countries. These agents and warehousing locations provide enough materials for the job to be done.

D.D.T. manufactures pumping units and mechanical piggs at its Lacombe location, with shipping out on a global basis. The decoking, descaling technology applied by DDT is so powerful that they guarantee complete coke and scales of all types removal from the tubes of fired heaters.

Orlande Sivacoe is the person who founded DDT, and also the person who invented DDT patented pigg. Since its foundation in 1991, with the wise leadership and knowledge of Orlande, the company now has clients in 51 countries around the world and more than 150 refineries. Since its beginnings DDT has focused on continuous development of its technology platform. With the right investment in technology, DDT has developed the best-in-class Pigg designs and mobile equipment. With more than 21 years working in this industry, the DDT operators and project managers are said to be the most knowledgeable and experienced people.

Variable-sized Piggs together with interchangeable appendages and mobile pumping units are the hardware components of the DDT process. The function of the pumping units is to control the Pigg position while the tube is being cleaned. Movement of the Pigg during cleaning is controlled by a pumping unit that uses pressurized water. DDT holds 22 patents on both hardware and process for decoking of fired heaters. The pumping units differ in size, which includes small containerized units for easy transport to difficult sites, motorized truck mounted units (single pump), and multiple pass units which includes dual pass and four pass units for faster cleaning performance. Coke and deposits will be entirely eliminated from the fired heater tubes.

The DDT service is a proven process that removes even the hardest coke and scale from furnace tubes. The system has shown its efficiency and has been proven to be much more effective than other traditional cleaning services such as the steam air decoking or chemical cleaning. The service does not involve the use of chemicals so that it is environment friendly as well.

With its proven effectiveness, DDT service has been become the solutions every refiner turns to for off-line decoking of fired heaters.
