Estudio comparativo de arcillas decolorantes utilizadas industrialmente en la operación de blanqueo de aceites de palma
The palm oil bleaching is an important operation in the refinement in which usually appears inconvenient, although the company’s processors have developed technical to control the quality of the crude oil and to conduct the operation easier of bleaching, is
considered unstable due to the variables that are handled. During the bleaching is retires of the oil soap plans, metals, phospholipids and substances that contribute colour, by means of the clay action launderers, who have pores and great superficial area, where the polluting agents are absorbed by physical effect, giving to purity and quality to the processed oil. In the national market are several clay marks; therefore arose the interest to determine that clay launderer displays better results in yield, removal of polluting agents and good properties to the refined oil. With the analyzed information of the experimentation, the incidences of each variable was evaluated and were the best conditions of agreed operation to the theoretical information and the experimental
results that are presented in this article. In Colombia the Tonsil marks are in great proportion (Sud Chemie) with 35%, Pure Flow (Oil Dri) with 50% and Filtrol (Engelhard) with 15% of the market. Other marks are not due to their lack of competitiveness in price.
