In this paper we formulate and apply the Exergy Analysis the set heat energy consumption elements of a typical plant of fishmeal, estimating experimentally the specific heat of the solid- liquid-vapor mixtures that form the raw material and steam, in order to optimize energy consumption by changes in the original installation and thus achieving the reduction in operating costs. Usually in these plants conventional energy balance and the premise that the specific heats are physical single phase flows is used; however, when solid-fat-water-steam mixture flows are presented, as is the case, these simple energy balances in each heating element become weak and lead to a high error margin in energy system assessment. In the methodology, the specific heats of mixture flows fat-water-vapor-solid is estimated by measurement of indicators in the industrial plant, contrasted with laboratory standar...

En el presente trabajo se formula y aplica el análisis exergético al conjunto de elementos consumidores de energía calorífica de una planta típica de harina de pescado, estimando de forma experimental al calor específico de las mezclas sólido-líquido-vapor que conforman la materia prima y el vapor, con el objetivo de optimizar el consumo energético haciendo modificaciones en la instalación original y logrando así la reducción de costos de operación. Generalmente en estas plantas se utiliza el balance energético convencional y la premisa de que los calores específicos corresponden a flujos monofásicos físicos; sin embargo, cuando se presentan flujos mezcla grasa-vapor-agua-sólidos, como es el caso, estos balances simples de energía en cada elemento térmico se hacen débiles y conducen a un alto margen de error en la evaluación energética del conjunto. Dentro de la me...
