Economic Impact of Fouling in Heat Exchangers The decision-making process regarding fouling can be driven by the need to solve an acute and recurring problem in the production. A heat exchanger or condenser subject to excessive fouling, with the need to be serviced (manually cleaned) in between scheduled turnaround moments, will obviously benefit from on-line [ ]. Heat exchanger fouling is a commonly occurring problem in different kinds of heat exchangers. It results in changing the heat transfer surface and reducing the overall heat transfer rate through that surface. During fouling, the surface of a heat exchanger wall develops another layer of solid material. This can happen for a variety of reasons.
(). Fouling of heat exchangers: characteristics, costs, prevention, control, and removal. British Corrosion Journal: Vol. 20, No. 4, pp. Fouling in heat exchange equipment results in a significant energy toss by increasing heat transfer resistance and fluid frictional resistance. This paper deals with an effective way to monitor fouling and describes a potentially useful diagnostic approach for discriminating different types of deposit in situ. Information regarding deposit type would be useful in selecting an appropriate.
Fouling reduces the heat transfer rate and increases the pressure drop of heat exchangers. Fouling mechanisms are broadly classified as sedimentation, chemical reaction, crystallization, and biological. Heat exchanger designs should accommodate these fouling mechanisms and guidelines based on the vast operating experience that are discussed. In chapter 3b the influence of heat exchanger-fouling on energy use in the sugar production in Zambia is explained using exergy analysis. Application of exergy analysis on heat exchangers in the sugar industry Sugar-cane and beet sugar are the two plants which are used as raw materials in the manufacture of sugar. Exergy analysis on.

Summary Heat exchanger fouling has long been recognized as a significant cause of energy inefficiency across many process industry sectors. In refining industry. Fouling of heat exchangers in the dairy industry has been investigated extensively and a large number of studies are reported in literature.
This review focuses on the mechanisms of milk fouling, detailing the role of protein denaturation and aggregation reactions as well as mass transfer. It has also been endeavoured to review the effect. Book April Analysis of Heat Exchanger Fouling in Cane Sugar Industry.

Bansal and Müller-Steinhagen (), in a study on crystallisation fouling in a plate heat exchanger with a corrugation angle of 60°, have shown that the fouling rate and the fouling resistance are inversely proportional to the velocity.
Furthermore, the earlier deposit in the plate is located downstream of the contact points, revealing a stagnant zone. heat under the temperature difference conditions for which it was designed.
Fouling of heat transfer surfaces is one of the most important problems in heat transfer equipment. Fouling is an extremely complex phenomenon [1]. Evaporation falls into the concentration stage of downstream processing and is widely used to concentrate sugar juice.
Fouling reduces the heat transfer coefficient of the evaporators and if the evaporators are rate-limiting raw sugar production is reduced. This chapter discusses the types and locations of the scale formed in the evaporators in the raw cane and beet sugar industries, showing case studies with detailed scale analysis.
Description This unique and comprehensive text considers all aspects of heat exchanger fouling from the basic science of how surfaces become fouled to very practical ways of mitigating the problem and from mathematical modelling of different fouling mechanisms to practical methods of heat exchanger cleaning.
cane sugar from the combined A and B massecuites is dried in fluidized bed or spouted bed driers and cooled. After cooling, the cane sugar is transferred to packing bins and then sent to bulk storage.
Cane sugar is then generally bulk loaded to trucks, railcars, or barges. Refined Sugar Production. Heat exchangers dimensioned to reduce fouling The production of sugar from cane or beets is a well-defined and energy-intensive industrial process (extraction, purification, evaporation, and crystallization).
By-product recovery through methanisation and cogeneration has become one of our clients’s major objectives. Sugar is produced in approximately countries from sugar cane and sugar beet. Cane sugar makes up 80 % of total annual production and is the primary source for 70 countries, while 40 countries rely on beet crops.
Only ten countries produce sugar from both sources. The top ten sugar producers, headed by Brazil, India and the EU, account for. At the British Sugar factory at York, they reuse condensate to heat the raw sugar juice immediately after crushing and steeping. This results in severe fouling on the raw juice fluid circuit as protein and dirt are deposited out on the surface.
At the Newark factory, they needed to boost production at one stage of the process which used pan vapours from a previous stage to heat the sugar.Heat Exchangers 73 individual thermal resistances of the system.
Combining each of these resistances in series gives: 1 UA = 1 (ηohA)i 1 Skw 1 (ηohA)o () where η0 is the surface efficiency of inner and outer surfaces, h is the heat transfer coefficients for the inner and outer surfaces, and S .At the British Sugar factory at York, they reuse condensate to heat the raw sugar juice immediately after crushing and steeping.
