Abstract: The present invention refers to a portable analysis system that, from analytical methodologies set based on digital images acquired by portable devices and accessories developed in an expedited way, allows the performance of the analytical test without technical deepening by the executor of the analysis. Such methodologies allow the evaluation of chemical species relevant to the O&G sector, for following up compositional parameters in aqueous samples and analytical monitoring of production and effluent treatment. Thus, a quick implementation is possible considering eventual diagnoses associated with the parameters of interest and following up of different processes. The application can be in any laboratory present in an operational unit, whether offshore or onshore, as well as it can be used for direct measurement in the field, depending on the necessary environmental and operating conditions.

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 describes the coprocessing of a lignocellulosic liquid stream and an intermediate fossil stream in the oil refining process comprising the steps of (a) contacting said intermediate fossil stream and said lignocellulosic liquid stream with a stream of solvent of C3-C10 hydrocarbons in an extraction section, obtaining a stream of extract with solvent and a stream of raffinate with solvent; and (b) sending said stream of extract with solvent to a separation section, obtaining a deasphalted oil stream comprising solvent-free carbon of renewable origin and a stream of recovered solvent. The present invention further relates to a process for producing fuels from the deasphalted oil stream comprising carbon of renewable origin, wherein the process comprises sending the deasphalted oil stream to a conversion section of an oil refinery.
