ALVAREZ, J. G.; ARMERO, J. M.  and  URRUTIA, C. A.. TEMPERATURE CONTROL IN SHELL-TUBE HEAT EXCHANGERS: A REVIEW OF THE INDUSTRY. Entre Ciencia e Ingenieria [online]. 2020, vol.14, n.27, pp.41-49.  Epub Mar 20, 2021. ISSN 1909-8367.  https://doi.org/10.31908/19098367.0005.

This review on temperature control loops in shell-and-tube heat exchangers is part of a study conducted to the industry in the region of Valle del Cauca where the following deficiencies were identified in the control engineering of heat exchangers: lack of knowledge of the model, inexperience in the selection of control strategies, poor tuning of control algorithms and lack of knowledge of performance evaluation criteria. The literature consulted shows a great number of methods of model identification and control strategies and tuning applied to heat exchangers, however, most of them are implemented at the simulation level, disregarding the non-linearities and interactions of the exchanger in the industrial process. The review presents different methods and concepts used to obtain models, control strategies, tuning and evaluation of control loops that are in the literature since 2010.

Keywords : Temperature control; industrial process control; PID controller; system performance; control design; delay systems; Closed loop systems..
