process for the application of the techniques of idroraffinazione catalytic production of kerosene for aviation and diesel

摘要

the invention relates to a process for the application of the techniques of idroraffinazione catalytic production of kerosene for aviation and automotive diesel fuel by means of a singlestage of treatment, characterized by the fact of processed a single office consists of two oil fractions which include aviation kerosene and diesel.and to understand the stages of: (i) to preheat the charge by means of heat exchange with the intermediate and final products; mix the office with a stream of hydrogen rich gas; heat ulteriormente office until reaching the temperature of reaction, to spend the office heated through at least one catalyst bed; refrigerate the office leaving the catalyst bedby means of heat exchange in ribollitori columns of stabilization and fractionation of the product; and cooling the reaction product by further heat exchange with the office;in one or more stages to separate the condensed constituents of the liquid phase at decreasing temperatures, food, without the use of means of pumping.these condensed, jointly or separately.in a first distillation column for the separation of light fractions and the quantity of dissolved hydrogen sulphide; food product to a second distillation column.for the splitting in two final products.
