2010 
Resumen Se hizo un estudio del uso del agua de imbibicion en la industria del azucar de cana de Cuba y, se revisaron mas de 200 fuentes bibliograficas llegandose a conclusiones importantes en cuanto a la cantidad y temperatura del agua de imbibicion, asi como la revision del esquema de imbibicion mas utilizado. A partir de aqui se obtiene un procedimiento para determinar la cantidad optima de agua de imbibicion teniendo en cuenta los precios actualizados del azucar y el bagazo como combustible y para otros usos, Es utilizado para su validacion en dos empresas azucareras de la provincia de Cienfuegos, se obtuvo que en las condiciones economicas actuales, es recomendable utilizar entre 10,4 – 15,4 % cana en dependencia del uso que se le de al bagazo y no entre 18-22 % cana como se viene haciendo historicamente, lo que permitio lograr un ahorro de agua de 66670,1 t, esto hace que se ahorren 9531.77 kWh de energia electrica por bombeo, permitiendo un efecto economico total entre 22939,92 – 218505,47 USD.

More than 200 bibliographical sources were reviewed reaching important conclusions as far as the amount and temperature from the imbibition water, as well as the scheme used of imbibition water most commonly used. A very simple procedure is obtained to determine the optimal amount of imbibition water considering the updated prices of the sugar and the bagasse as fuel and for other uses. It is applied for his validation in two sugar companies of the province of Cienfuegos. In the present economic conditions the results showed that it is advisable to use an amount of imbibition water between 10.4 -15,4 % of the amount of cane processed based on the use of the bagasse and not between 18-22% as it is historically done. It resulted on 66670.1 tons of water and 9531.77 kWh of electrical energy saved. The total economic effect was between 22939,92 - 218505,47 USD. Key words: imbibition, energy, sugar mill.
