In the past few years, the Brazilian oil and gas sector had a considered growth, gaining enough relevance at international level, and being extremely important for the Brazilian socioeconomic development. However, the sector is still limited due to technical deficiencies. This work aims to conduct a current study, comprehending the entire oil chain, since it is possible to mention the Brazilian market updates on this context. To support this study, the historical development of the Brazilian petroleum industry was presented and the main stages of the production process were exposed with an emphasis on exploration and production phases. The new technologies developed for deepwater extractions, such as the pre-salt regions, were also discussed and, in the end, the relation of this growing market with the opportunities of the Human Resources Program of n. 48 was highlighted. This program identifies the market's actual needs and it's scarce's areas with the purpose of building capacity and qualified workforces, since it is also aimed, in a national level, a self-sufficient human resources for the sector

Stricter environmental policies are shown necessary to ensure an effective pollutant emission control. It is expected for the present year of 2015, that Brazil will assume, at the 21th United Nation's Climate Change Conference (COP21), implementation of commitment to a low carbon economy. This positioning affects the industrial environment, so that is deemed necessary to search for new technologies, less aggressive to the environment, so the adequacies to the new emission policies do not cause a negative effect on production. Almost all of the processes performed in the steel industry demand burning fuel and, therefore, flue gases are sent to the atmosphere. In this present work is discussed the utilization of heat exchangers so, by recovering part of the available heat from the flue gases of certain industrial process, the combustion air is preheated. The combustion air preheat results in less energy requirement, i.e., less need of fuel consumption and, in addition, minor amount of pollutants to be emitted. Due to better fitting to the process, it is studied the utilization of spiral plate heat exchangers. The heat exchanger dimensioning is made by an iterative method implemented in the software Microsoft Excel. Subsequently are analyzed the gains in terms of process's thermal efficiency improvement and the percentage of fuel saving. The latter implies in reduction of the same percentage of greenhouse gases emission

The world population is growing at exponential scales, thus the demand for food grows significantly. The use of pesticides is seen as a way to meet the demand for food and increase the efficiency and productivity of the agricultural sector. BASF SA in partnership with packaging suppliers represent a remarkable scene in the Brazilian market in the agrochemicals sector. In 2014, the Department of Agro from BASF Packaging, identified in its production process certain deformation of its rigid packaging during the filling process of pesticides. This phenomenon is probably caused by the low resistance to compression that the package is used. In order to eliminate the deformation of rigid packaging arising from the filling step, a study will be conducted in conjunction with the supplier JET UNIPAC whose on line problems occurred more frequently. The study is to identify the strength of the rigid containers standardize a compression resistance value at which the package is not deformed after the filling step. This study will present an investigation through experiments combined with theoretical concepts in order to determine possible causes for the emergence of this phenomenon. At the end of the study, a solution to eliminate or reduce to the maximum the packaging deformation problem appears
