The installation comprises a tank (10) containing oils and/or fats to be treated and a tank (11) containing light alcohol, pumps (3) and (4) feeding said materials to a tubular reaction vessel (30) having a winding configuration provided with heating means for internally maintaining a supercritical temperature with respect to the alcohol used and a pressure, for producing esterification and transesterification reactions, without the presence of catalysts of said oils and/or fats and alcohol, a heat exchanger (8) for heating the affluents and cooling the reaction effluents and a reaction effluent depressurization tank (21). The installation further comprises means (22, 23, 28) for stirring the reaction product at the reaction temperature and pressure in one or more segments of the tubular vessel (30) covering a sector of the reactor before its end area for exit towards the depressurization tank (21). |
