Abstract: The present invention addresses to a system and methodology for evaluating the deposition in tubes of the furnaces of delayed coking unit (DCU) in order to reduce the costs involved with premature shutdowns. With this system, load rankings are obtained, influences of certain loads on processing are evaluated, and additives that reduce deposition are further evaluated. Consequently, the results obtained by such a system allow greater flexibility for the follow-up engineer to optimize his delayed coking unit in order to increase load or increase the unit campaign time, drastically reducing costs in premature shutdowns, or increasing its return by increasing load and shutdowns, since the load is limited by the degree of deposit formation, and that directly affects the wall temperature.

Abstract: The present invention addresses to a method for characterizing water produced in oil samples containing water with contents below 0.5%, by measuring the analytes of interest directly in the oil containing the emulsified water. For this, it is necessary to carry out filtrations to remove possible suspended solids, since they may interfere with the composition of the water. The method proposed in the present invention provides methodologies with and without interference in the equilibrium by washing the oil with distilled water, measuring the analytes of interest directly in the oil.

Abstract: The present invention relates to a process for the production of bio-oil-based renewable streams for composing a diesel or aviation kerosene (AVK) pool by combining the technologies of hydroprocessing esters and fatty acids (HEFA) and thermochemical conversion of lignocellulosic biomass for generating bio-oil. The integration of conventional raw material from the HEFA pathway with a bio-oil fraction has the advantages of the use of a stream originating from the conversion of lignocellulosic material, which is widely available on the market, and also the production of a renewable stream containing aromatics in its composition.

Abstract: The present invention relates to a method for detecting and mapping the spatial distribution of organic compounds aiming to understand how such organic compounds are distributed on the surfaces of reservoir rocks subjected to injection fluids for oil recovery purposes. The DESI and LAESI techniques may be used in the analysis of rocks from trials of oil recovery in small or large scale. Furthermore, both techniques may be applied in the analysis of compounds present on the surfaces of minerals from aquatic environments.

Abstract: The present invention discloses a portable system comprised of an electrochemical cell for batch injection analysis (BIA) coupled to a copper oxide electrode for the selective determination and quantification of monoethylene glycol (MEG) from different petrochemical samples with application in the environment laboratory and in field analyses, aiming at the quality control of these samples by portable methodology and in a short analysis time.
