Book excerpt: 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. The problems that restrict the efficient operation of equipment are described and the costs, some of them hidden costs, that are associated with the fouling of heat exchangers are discussed. Some simple concepts and models of the fouling processes are presented as part of the introduction to the subject. Advice on the selection, design, installation and commissioning of heat exchangers to minimise fouling is given. A large part of the text is devoted to the use of chemical and other additives to reduce or eliminate the problem of fouling. Another large section is designed to give information on both on-line and off-line cleaning of heat exchangers. One of the difficulties faced by designers and operators of heat exchangers is anticipating the likely extent of fouling problems to be encountered with different flow streams. Another large section addresses the question and describes methods that have been used in attempting to define fouling potential. The book concludes with a chapter on how fouling information can be obtained using plant data, field tests and laboratory studies.

Available in PDF, EPUB and Kindle. Book excerpt: The present investigation has been under taken to estimate the reduction in the heat transfer rates on account of fouling in a plate heat exchanger with different types of milk mass flow rates preheating temperatures and acidities. The experimental trials were carried out with buffalo whole milk and also of mixed (buffalo+cow) whole milk. It was observed that scaling was profoundly influnced by flow rate of milk and faster flow rates were found to result in reduced deposition. pre heating was singly important as it offected scale formation. The formation of doposit in a plate heat exchanger was greathy reduced by forewarming milk. Soil deposits decreased linearly with the increase.

This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Control of scale formation in heat exchangers using simulated geothermal waters can be achieved by lowering the pH of the water to pH 6 or lower. This does not, however, appear to be an economic approach for highly buffered geothermal brines and would lead to severe corrosion problems. Two commercial scale control agents, Calgon CL-165 and Monsanto Dequest 2060, showed promise of effecting scaling in a minor way and should be tested further on actual geothermal waters. Other scale control methods tested were unsuccessful. These included seeding experiments, turbulence promotin and electostatic and electromagnetic devices reputated to modify scale formation. The experiments were performed with tube-in-shell heat exchangers using simulated geothermal waters prepared from a salt dome solution based brine. The scale formed was primarily silica with a small percent of calcium carbonate and traces of magnesium and iron. Physically it was a hydrous soft solid adhering only lightly to the heat exchange surface. This is not typical of geothermal water scales encountered in high temperature brine operations and the results of the scale control expeirments should be evaluated with that in mind.

Available in PDF, EPUB and Kindle. Book excerpt: A system to generate a 1- to 3-gallon per minute stream of 350 F (177 C) simulated geothermal brine is discussed. A 10,000-gallon tank serves as the brine holding tank. The solution is prepared by diluting 26% sodium chloride, derived from a Gulf Coast salt dome with steam condensate, deaerating, heating the brine to 350 F in a steam heat exchanger, injecting the desired cations and anions into a flowing stream with chemical injection pumps, and mixing with in-line mixers. Non-scaling cations are normally added to the 10,000-gallon base brine solution; anions, such as bicarbonate, silicate, etc. are injected as the sodium salts. Sulfide is injected separately as sodium sulfide solution. Hydrochloric acid is injected to adjust pH to the desired 6-8 pH unit range. Composition of the resulting simulated geothermal brine may be varied over wide ranges for each component. The system is presently in operation on a hydrogen sulfide oxidation study while heat exchangers are being constructed for the scaling studies. Two heat exchanger systems will be used. The first is a large U-tube exchanger designed to receive the hot brine on the shell side with cool water circulating in the tubes. The second is a series of three smaller straight tube exchangers with the hot brine in the tube side. Both systems will be completely instrumented to measure heat transfer coefficients in each exchanger. Proposed experiments include: addition of scale control agents, injection of carbon dioxide to prevent carbonate scaling, and exploration of the effects of electrical and magnetic fields on scaling.

Book excerpt: Deluging of air-cooled heat exchangers with water during warm periods holds the promise of increasing heat rejection capability and reducing the cost of dry cooling. One of the principal uncertainties in the use of the deluge concept is the tendency toward deposition of solids from the delugate. Small amounts of calcium carbonate scale may significantly reduce the cooling efficiency of a deluged system by reducing the heat transfer coefficient and interfering with delugate flow. Thus the question of delugate water quality is of major importance in evaluating scale formation and its effect on heat transfer in the deluged dry cooling system. The paper discusses, in relation to the deluged dry cooling system, the importance of scale prevention, the theory of scale formation and application of this theory to the deluged system, the problems of delugate evaporation, and delugate treatment required to prevent scaling.
