摘要

The heat exchanger fouling and cleaning community is confronted with new challenges that have not been foreseen in the past and with old problems that are increasingly getting worse. For example, the automotive industry utilizes more heat exchangers to meet efficiency and emission standards by reducing NOx through exhaust gas recirculation (EGR) coolers. While theoretically very effective, this technique has been severely hindered by rapid formation of various types of deposit on the cooler surfaces. Along the same lines, oil refineries nowadays have to cope with heavier crude oils or densified residuals with higher risk of fouling from sources that until recently have not been economical to process. World population growth, particularly in arid areas, demands more potable water, which is mainly produced from seawater, which in thermal desalination units is prone to the chronic formation of deposits. Numerous studies have shown that heat exchanger fouling may be responsible for 1-2.5% of global CO_2 emissions. Cost penalties due to fouling, for example, for additional fuel, down-time, overdesign, cleaning chemicals, and so on, have been estimated as about 0.25% of the gross domestic product (GDP) of industrialized nations.
