摘要

Heat exchangers are the workhorse of most chemical, petro-chemical, food-processing, and power-generating processes. The global heat exchanger market is estimated to top a total of $12,7 billion by 2012, with an increase of 3-5% per annum [1]. Despite this very positive market outlook, manufacturers are under increasing pressure to produce heat exchangers that are more efficient in terms of heat recovery and use of material, while at the same time being faced with fluids that are increas-ingly difficult to process. One major problem directly related to these requirements is the deposition of unwanted materials on the heat transfer surfaces, which occurs in the majority of heat exchangers [2]. Conservative studies estimated that heat ex-changer fouling leads to additional costs in the order of 0.25% of the gross domestic product (GDP) of industrialized coun-tries, and that it is responsible for 2.5% of the total equivalent anthropogenic emissions of carbon dioxide [2, 3].
