Article
First-generation sugarcane ethanol production is a well-established technology. However, second-generation ethanol is not yet consolidated in industries. Under these circumstances, this work presents a multi-objective optimization of this process focusing on economic and environmental objectives. The impact of the Brazilian decarbonization program...
Chapter
According to the Brazilian federal program called Renovabio, biofuels producers will earn a number of carbon credits, known as CBios, proportionally to the reduction of greenhouse gases emissions. These CBios will be sold by biorefineries to fuel distributors in Brazil. Thus, the environmental performance will have a direct impact on the economic p...
Article
During the transition to a low carbon economy, techno-economic-environmental analyses of industrial processes will have increasing relevance. Within this context, the replacement of hexane by ethanol (either hydrous or anhydrous) as solvent for soybean oil extraction is assessed. Sugarcane bagasse was the fuel for cogeneration of energy. All proces...
Conference Paper
This work assesses the techno-economic-environmental feasibility of technological routes for biodiesel production from soybean oil. Two scenarios were analyzed: the conventional biodiesel production process, in which soybean oil is extracted using hexane as solvent, and the transesterification of this oil is accomplished by a methanolic route; the...

Brazil signed in 2015 the Paris agreement and committed to rising the renewable sources share in the Brazilian energy grid, what includes biofuels production. In order to comply with this agreement, the Brazilian government issued the "RenovaBio" law, which aims to stimulate the energetic efficiency in biofuels production and to compensate the biof...
Conference Paper
In this work, a Nonlinear Model Predictive Control (NMPC) strategy is investigated on a rigorous pressure-driven dynamic model of a depropanizer distillation column, implemented in a dynamic process simulator environment. Depropanizer distillation columns are present in Natural Gas Processing Units (NGPUs) for the separation of the propane from iso...

Conference Paper
According Paris agreement signed in 2015, Brazil has committed itself to decrease, until 2025, 37% of the greenhouse gases emissions based on 2005 year. Other commitment made was that the renewable energy proportion should reach 45% until 2030. In this climate change background, the replacement of raw materials from non-renewable sources by the one...
Chapter
This work investigates the application of Nonlinear Model Predictive Control (NMPC) using Hammerstein Models in an offshore oil production well with gas-lift. The problem is especially challenging from the control point of view because it presents regions with gain sign inversion. This reversion of the gain direction makes this problem difficult to...

Potassium is an essential ion for plant nutrition, usually supplied in the format of chlorides and sulfates. Within the conjuncture of the Brazilian mineral production it is necessary to import carriers of this chemical element (of the order of 80% of the demand) in order to supply the demand of the national agricultural sector. In this way, initia...

Cryogenic Air Separation is a technology that allows the largest capacity of production at a moderate to high-purity level. The core of this technology is the Distillation Double-Column System, a very complex process due to its condenser-reboiler heat integration that requires a precise control of the many variables involved. Other characteristics...

During the exploitation of off shore oil and gas, the produced fl uids fl ow from the formation into the wellbore and then into the tubing and fl owlines to fi nally reach the topside primary processing system. There, these produced fl uids are heated and separated into water, gas and oil in a three-phase separator due to the diff erence of density...

In this work a hybrid methodology based on statistical approach and phenomenological modeling was developed aiming the monitoring of the performance of compression equipment in an offshore oil platform. A rigorous model was employed in order to estimate thermodynamic based values of the performance of the compression system, given by the polytropic...

Thesis
Full-text available
This study proposes a new approach for history matching based on Kernel PCA (KPCA) and Genetic Algorithm to adjust the reservoir permeability field. The history matching is an inverse problem, with huge dimensionality, where some parameters of the reservoir model are adjusted so that the simulation of the mathematical models could be able to make a...

This work proposes a new approach for history matching using Kernel PCA to adjust the reservoir permeability field obeying geostatistical constraint. Although there are several methodologies in literature for history matching, most of them don't take into account geostatistical restrictions. Besides, history matching is a problem of huge dimensiona...
