Further refinement of heat exchanger design procedures will only be possible in conjunction with more sophisticated methods to include the effects of fouling. While the installation of excess heat transfer surface may extend the operation time of heat exchangers, it provides no remedy against the ...
FOULING: THE ULTIMATE CHALLENGE FOR HEAT EXCHANGER DESIGN The costs caused by the process related formation of deposits on heat transfer surfaces are in the order of 40,000 million dollar U.S. per year, for the to... HMG Mullersteinhagen 被引量: 0发表: 0年 High efficiency solar air heat...

Crude oil fouling in refinery preheat exchangers is a chronic operational problem that compromises energy recovery in these systems. Progress is hindered by the lack of quantitative knowledge of the dynamic effects of fouling on heat exchanger transfer and pressure drops. In subject of this work is...
And reduced by processes that result in shear waves in the fluid to excite vibration to the heat exchange surface by applying a mechanical force to the fixed heat exchanger adjacent to the heat exchange surface, the fouling of the heat exchange surface. By applying the dynamic actuator coupled ...
The studied cases include fouling and underneath corrosion in heavy diesel oil (HOD) heat exchangers, fouling in glycol heat exchangers and fouling in vertical thermosyphon heat reboilers.doi:10.1615/1-56700-172-6.210Jamil J. Al-BagawiS. Said...
The objective of this paper is to pre-determine the fouling factor and cleanliness factor obtained in the heat exchangers to avoid the degradation and capital cost losses obtained during the heat exchanging process. The performance factor of heat exchangers degrades with time due to scaling or ...
outlet temperatures of the hot and cold streams with time to plan the optimum cleaning schedule of heat exchangers that provides the minimum operational cost or maximum amount of savings.In this paper, the simulation of heat exchanger networks is performed by choosing an asymptotic fouling function....

Fouling of food process plant surfaces and the subsequent cleaning needed is a significant industrial problem, and as the cost of water and chemical disposal increases, the problem is becoming more significant. Current literature on water-based cleaning is reviewed here according to the classification...
