Produced water is effluent is inherent in the process of the entire oil and gas chain, variations and concentrations of contaminants are differentiated by location and maturation of petroleum reservoirs. With oil and gas extracted, the volume of water produced rises and may reach a limit where it is decided the closure of the production of a reservoir due to its high cost for processing of effluent. For treatment, there are several technologies available in the market. Accordingly, studies and researches seeking new forms and sources to minimize costs and impacts of the treatment process with efficiency to removal of contaminants. Based on this information this paper presents research on the generation and treatment of produced water. 2015-10-01T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/8354 Título: Estudo da sedimentação de cascalhos de poços de petróleo em um fluido de perfuração à base de glicerina, goma xantana e óleos vegetais Autor(es): Porto, Carla Corina dos Santos; Jesus, Janiele Costa; Britto, Antony Passos; Maciel, Samia Tássia Andrade; Cunha, Acto de Lima; Santos, Joao Paulo Lobo dos; Silva, Gabriel Francisco Abstract: The drilling fluids are complex combinations of several compounds that are used in oil activity to secure and assist the oil exploration process.They can assume aspects of suspension, colloidal dispersion or emulsion. Usually, they are employed in the clean up of gravel generated at the deep end by the drill and transport the same to the surface. The transport of these gravels to the surface it has been a major concern of in this area, given that an inefficient process in cleaning of wells can lead to problems that might prevent continuation of operation.This study aimed to develop a glycerin-based drilling fluid in order to improve the sedimentation of gravel; accelerating the removal time and decrease affectivity of the fluids of the environment. 2015-10-01T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/8353 Título: Avaliação de um meio adsorvente a partir da Moringa oleifera Lam para uso no tratamento de água produzida Autor(es): Dias, Brenda Avila; Santos, Kryslaine Machado de Almeida; Santos, Douglas Costa; Maciel, Tássia Andrade; Silva, Gabriel Francisco Abstract: The produced water, originated from the extraction and production of petrolium, has a high content of oil and grease, so, due to this factor the necessity of treatment. The study is to develop a treatment of water produced using two byproducts of crushed Moringa oleifera Lam, acting as a means adsorbent for removal of TOG: the full crushed pod (with seed) and the crushed pods without seed and without the spongy part of moringa. To analyze the design efficiency a chemical study was done on laboratory scale with the aid of the BET Analysis and it was concluded that Sample B obtained a better choice because it showed a high surface area, how bigger is the surface area of the adsorbent, higher is their interaction with the adsorbate. To the total pore volume, the Sample B showed better results, how greater is the volume, better is the adsorbent function. With the provided data was possible to construct the adsorption and desorption isotherms for each sample, the samples A and B are classified in mesopores (2-50 nm), according to IUPAC. From the results, and comparisons with products used, was observed the efficiency of the byproducts of Moringa oleifera Lam as adsorbent means that can replace them in the industry as an alternative means. 2015-10-01T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/8352 Título: Perspectivas de gerenciamento de resíduos e gestão de impactos ambientais na orla de Atalaia em Aracaju/SE Autor(es): Rodrigues Junior, Jocimar Coutinho; Stingelin, Fernanda de Souza; Rocha, Daniella; Barros, Glauber Vinícius Pinto Abstract: The main Brazilian cities was initially developed around the coastal regions, in view of this, urbanization on the coast have been characterized by intense alteration and deterioration of the landscape. The economic importance of the borders of Brazil's beaches have given the high relevance encompassing tourism is fully linked to environmental value and the natural coastline and coastal regions represent. In this regard, several buildings are installed around the edge of the adjacent vicinity to the point of being endangering environmental and social resources. The city of Aracaju and the Watchtower Orla fit into this context. Thus, this study aims to verify how is the waste management in Orla de Atalaia and provocative note the main sources of impacts and the consequences of these acts. In view of this, we can ascertain that the Aracaju city Orla even with a good state of conversation, there is the presence of actions that can possibly be harmful to the environmental and society, causing environmental impacts in the long and short term. The disposal of waste from leisure activities and construction in the study area occurs in parts so that you can come harm the soil and water resources, due to the pollution caused. Thus, conservation and proper management of the Watchtower Orla are extremely important to meet economic purposes jointly with the environmental balance. 2015-10-01T00:00:00Z
