Important experiences related to the oil industry and energy efficiency, including performing energy diagnostics on offshore extraction, separation, compression and pumping systems. Determining the efficiency of crude oil pumps, gas compressors, amine regeneration furnaces and gas turbines under real conditions constitutes an important technical task that requires and adds technical expertise. Feasibility analysis for the final disposal of acid gas in different destinations, or the use of flare gas as an energy source.Design and construction of a pilot plant for the calcination of clays entrained in an air current. Increase in the reactivity of clay materials to be used as additives in cementitious mixtures.Energy diagnostics for the detection of anomalous energy consumption in industries. Recommendations and implementation of corrective measures.
