With increasing pH-value the number of free hydrogen ions decreases, which keep the calcium ions in solution. The ratio of free hydrogen ions can be described by the saturation index which is calculated by the reaction equations and the equilibrium constants. It can be seen, t...T. Reg ...
Fouling Factors in Heat Exchangers The fouling factors to be used in the design of heat exchangers are normally specified by the client based on their experience of running the plant or process. If uncontrolled, levels of fouling can negate any benefits produced by careful heat exchanger design....

The Heat Exchanger Fouling and Cleaning Conference is a biennial event that brings together experts from industry, academia, and research centers to share their latest research and technological developments in fouling mitigation and cleaning strategies.
Fouling of heat exchange surfaces is mitigated by a process in which a mechanical force is applied to a fixed heat exchanger to excite a vibration in the heat exchange surface and produce shear waves in the fluid adjacent the heat exchange surface. The mechanical force is applied by a dynamic...
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...

Particulate fouling in an Alfa-Laval P20 plate heat exchanger was investigated using a suspension of aluminum oxide particles in heptane. Process parameters such as flow velocity, heat flux, and particle concentration were varied over a considerable range. In this paper, the influence of the above...
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 ...
