Tube cleanliness verification has become a key demand from clients. Mechanical decoking and descaling operations have typically relied on judgment and subjective interpretation of pressure/flow indications. For some time the industry has been obliged to accept this, but has been seeking a more reliable method of scientific evidence.
Within the mechanical cleaning process various techniques and indications are used to judge the internal cleanliness of process tubing. These may include:
Such measures can be rather qualitative, judgmental and subject to human error, as well as exaggerated claims.
By deploying a Cokebusters’ intelligent pig it is now possible to ‘see’ inside the entire process and verify the degree of cleanliness.
Our intelligent pig is deployed during and following mechanical cleaning operations using the same connection arrangements. In a time efficient operation the data gathered from the intelligent pig can be used to accurately locate and verify thickness of residual internal coke or scale. Equipped with this knowledge, the mechanical cleaning operators are then able to perform a safer and more efficient service by concentrating their efforts only on the process tubing where fouling remains.
A critical advantage is the practice of combined service which Cokebusters patented in 2007. Our mechanical cleaning operators and inspection technicians are colleagues working together, communicating seamlessly. In newly constructed assets an inspection can be carried out to provide a baseline which can be very helpful as a record for future operations. In certain circumstances a pre-decoke/descale inspection can be carried out; more usually the piping inspection runs in harmony with the mechanical cleaning to bring the operation to a successful conclusion providing coke/scale removal verification.
Cokebusters are aware of the negative impacts that the daily running of the business can have on the environment. Our aim is to prevent and minimise this impact, whilst continuously creating positive improvements to ensure a positive effect on our local environment and globally.DOWNLOAD POLICY
