Overview
Mechanical cleaning, otherwise known as mechanical decoking or descaling, helps ensure the optimal performance of fired heaters utilized in the refining and
petrochemical industries. Internal fouling can reduce production throughput and prevent the proper transfer of heat to the feedstock, which can lead to elevated tube temperatures and eventual tube failures. As such, it is imperative that all fouling is removed to achieve target run times and throughput.
While the mechanical cleaning process can be quite effective, the methods to confirm the overall cleanliness of a heater coil do not provide adequate assurances that all of the fouling has been removed.
Quest Integrity’s Advanced Decoking & Cleanliness Verification (ADCV) empirically detects and measures internal fouling, thereby eliminating any uncertainties in coil cleanliness. This is accomplished using specialized ultrasonic-based technology, software, and proprietary cleaning methods. By applying Advanced Decoking and
Cleanliness Verification, owner/operators are able to use data-driven solutions that can reduce decoking times, reveal unexpected operational issues and validate cleaning
efforts, allowing assets to return to service faster and with better operational assurances.
