Abstract
A system and method for cleaning coils in a fired heater is provided. The cleaning system includes a data acquisition tool configured to pass through the coils to acquire data. The cleaning system is configured to establish a pre-cleaning fouling baseline derived from the data for the coils. The cleaning system is configured to develop an optimized cleaning plan for the coils based on the pre-cleaning fouling baseline. The optimized cleaning plan includes a focused cleaning for a fouling area in the coils. The cleaning system further includes at least one cleaning pig configured to clean the coils based on the optimized cleaning plan. The cleaning system further includes a decoking truck for cleaning the coils with the cleaning pig based on the optimized cleaning plan.
