The detection and cleaning of fouling in pipes is currently a significant problem in process industries. The presence of fouling causes a substantial increase in plant operation costs for a number of reasons, and potentially causes contamination of products. Process efficiency is also reduced. A number of methods and patents have been developed to address these problems and various mechanical, chemical, or combined tools have been employed to date. Most of these procedures require halting production and consequently there is a considerable cost associated with existing cleaning processes. In addition, these processes bring about significant environmental and safety implications, as they often involve hazardous cleaning substances. Novel techniques are researched in this study to improve these conventional methods and create solutions that are cheaper, safer and more environmentally sustainable. A critical review of the state of the art of these methods is presented, including approaches based on ultrasonic vibration of the pipe. This paper also seeks to analyze limitations that are pertinent to the prevention of fouling in pipes. Finally, an overview of recent developments in this area, with an emphasis on potential market opportunities, is presented.
