Heat Exchanger Fouling Articles & Analysis

An extensive investigation of the effect of fouling on heat exchangers performance has been carried out based on the first and second laws of thermodynamics. Non-dimensional fouling thermal resistance is firstly defined, and five typical criteria in terms of heat transfer units number, heat transfer effectiveness, exergy transfer units number, exergy transfer effectiveness and non-dimensional ...

In every situation where a heat exchanger is required, the combination of products and service fluids, application, temperature and other variables will be different. Understanding these properties ensures the correct heat exchanger is supplied. For example, high fouling materials may require a scraped-surface unit. Having adequate information will also ensure that the heat exchange process does ...

ABSTRACT A diesel emissions control system built and tested on an industrial forklift truck is described. The system utilizes a pleated media type diesel soot filter. The temperature limit of the filter material is well below the temperature of the exhaust gas. Therefore, cooling of the exhaust gas is necessary. A finned-tube heat exchanger is included in the system to cool the exhaust gas to ...

The Situation A California refinery produces xylene for use as commercial product and a precursor for petrochemical manufacturing. A primary component to the production of xylene is the isolation and purification of the chemical from a complex mixture of petroleum hydrocarbons. Steam based heat exchangers are used to process the xylene. Inherent to the design and rough duty heat exchangers face ...
