Residual oils from combustion engines, from the industrial sector of Mamonal in Cartagena de Indias, were characterized by densimetry, karl fischer, viscosimetry, atomic absorption and pump density, percentage of humidity, viscosity, metals in suspension and calorific value Designed, constructed and tuned according to ASTM D 240-02. The calorimetric pump was designed in stainless steel 304 schedule 40, with circular section and internal volume of 355,71 mL. It works in an atmosphere of oxygen with pressures between 25 and 30 atm. The temperature sensor used was the SEE TMP-BTA with stainless steel probe and the data-software acquisition system used was VERNIER International's GOLink SEE with a sensitivity to the hundredth degree. It was determined that the higher calorific value (PCS) of the samples of used oils from the industrial sector of Mamonal have an average value of 19934.3 Btu / Lb.
