SANCHEZ-ESCALONA, Andrés A.; CAMARAZA-MEDINA, Yanán; RETIRADO-MEDIACEJA, Yoalbys  and  GONGORA-LEYVA, Ever. Heat transfer incremental on a jacketed coolers system through optimization of the water flowrates. Enfoque UTE [online]. 2020, vol.11, n.4, pp.71-86. ISSN 1390-6542.

This research proposed an optimized water distribution scheme in order to increase the heat transfer on a hydrogen sulphide gas coolers system. The system is comprised by two jacketed shell and tube heat exchangers, installed in a series-parallel arrangement. Each equipment operates with three streams, hence two major thermal communications are present. The water flowrates optimization was performed through genetic algorithms, using a model based on the ɛ-NTU method for simulation of the heat exchangers. The heat transfer incremental was estimated within the range 3695 to 10514 W, while the gas temperature reduction at the system outlet was projected between 2,9 and 9,8 K. Calculated heat recovery varied from 3,90 to 22,16%, averaging 12,44%. Multivariate linear regression was implemented for determination of the functions that solves the studied problem from a technological point of view.

Keywords : genetic algorithms; energetic efficiency; heat exchangers; optimization; rational water usage.
