SANCHEZ ESCALONA, Andrés Adrián; GONGORA LEYVA, Ever; ZALAZAR OLIVA, Carlos  e  ALVAREZ HERNANDEZ, Edel. Heat exchange and fouling analysis on a set of hydrogen sulphide gas coolers. Min. Geol. [online]. 2017, vol.33, n.3, pp. 324-338. ISSN 1993-8012.

The sulphide acid coolers are tube and shell jacketed heat exchangers designed to cool down the produced gas from 416,15 K to 310,15 K in addition to separate the sulphur carried over by the outlet gas from the reactor tower. The investigation was carried out by applying the passive experimentation process in an online cooler set in order to determine the heat transfer rates and fouling based on heat resistance. It was corroborated that the operation of this equipment outside design parameters increases outlet gas temperature and liquid sulphur carryovers. Efficiency loss is caused by fouling elements in the fluid, which results in changes in the overall heat transfer rate. The linear tendency of the fouling heat resistance based on time for three gas flowrates.
