An Integrated Reactive Separation Process for Co-Hydrotreating of Vegetable Oils and Gasoil to Produce Jet Diesel (original) (raw)

2018

Abstract

An integrated reactive separation process for the production of jet diesel from vegetable oils and gasoil mixture has been developed. The integrated reactive separation process consider three interconnected sections: 1) a triglyceride hydrolysis section consisting of a catalytic heterogeneous reactor which is used to transform the triglycerides of the vegetable oils or animal fats to the corresponding fatty acids and a coupled decanter-distillation column to separate the fatty acids from glycerol and water; 2) a co-hydrotreating section where a reactive distillation column is proposed to perform the deep hydrodesulfurization (HDS) of gasoil and the hydrodeoxigenation (HDO) and the decarbonilation of the fatty acids simultaneously and 3) a isomerization section where a catalytic reactor is used to produce the jet diesel with the appropriate fuel properties. Through intensive simulations the effect of the different operating variables of the three sections were studied. Results show t...
