Fouling - an overview ScienceDirect Topics

Fouling is a complex interplay of the chemical system, material of construction, operating conditions (including pressure, temperature as well as vapor and liquid loads), and the specific geometry of the given internal. If a chemical system is prone to fouling, no design will ever be able to completely avoid it.

FOULING - A-to-Z Guide to Thermodynamics,

In fouling associated with combustion, the fouling on heat exchangers may be due to particle deposition, chemical reactions and corrosion as described earlier. It will be clear from these two examples that the process of fouling may be extremely complex necessitating, as it does, a rather empirical approach to its understanding and investigation.

16-02-2006  TEMA fouling factors have been used for decades in heat exchanger design, with values that have remained unchanged for a long time. Although TEMA indicates in its publication of fouling factors that such values should be used only when more accurate information is not available, industry has had a tendency to use such values as the standard approach.

Organic Fouling and Chemical Cleaning of

Fouling and subsequent chemical cleaning of nanofiltration (NF) membranes used in water quality control applications are often inevitable. To unravel the mechanisms of organic fouling and chemical cleaning, it is critical to understand the foulant−membrane, foulant−foulant, and foulant−cleaning agent interactions at the molecular level.

Fouling and its effect on the thermal

Nevertheless, fouling is dependent on the external physical chemical and other variables of the hot and cold fluids as discussed earlier. The variable B in these equations is dependent on the external and other physical and chemical factors leading to fouling and it is an unknown dependent on the specific nature of hot and cold fluids.

Heat exchanger fouling - EnggCyclopedia

Freezing fouling, precipitation fouling and reaction fouling mainly originate because of the change in the fluid temperature. If the temperature difference between the heat exchanger wall and fluid is high, then the fluid close to the wall is most likely to cause fouling because of high temperature change.
