The purpose of this study was to investigate the feasibility of obtaining biodiesel using calcined agroindustrial residue ashes from Huasaí (Euterpe oleracea mart) as a solid catalyst in the transesterification of used vegetable oils. The agroindustrial residues were collected from Negocios Agroindustriales Loreto NALSAC, while the used vegetable oil was obtained from the facilities of FUNDESAB. A comprehensive physicochemical characterization of the used vegetable oil was conducted, revealing moisture values of 0.76% and acidity degree of 0.62%. The Huasaí agroindustrial residues underwent a drying process at 90°C for 2 hours, followed by pulverization and calcination at 700°C for 4 hours to obtain the CCRAH catalyst, whose analyses revealed a potassium concentration of 16.51% and calcium of 7.19%.During the direct basic transesterification reaction, a maximum biodiesel yield of 80....

The main objective of this degree work was: To perform calculations of energy losses in the pipes, accessories and flow meters in the hydraulic bench of the Unitary Operations and Processes laboratory of the Faculty of Chemical Engineering of the UNAP for it is operation. The present quantitative research was of a descriptive type, the results were explained in the fluid mechanics equipment, as well as in the accessories (elbows, expansions, orifice plate, flow meters such as the Venturi tube, flowmeter, rotameter, etc.). The equipment, as it is intended for academic purposes, has galvanized steel pipe of different diameters (1/2", 3/4", 1 1/2", 1” and 2”), in which different phenomena can be observed. It was determined that the total experimental friction losses (Experimental or real flow rate of 34.2 LPM) have an error of 26% compared to the theoretically calculated one (Theoretica...
