2. Desenvolvimento de um sistema de recirculação com uso de wetlands construídas para efluentes da piscicultura / Development of a recirculating system using constructed wetlands for aquaculture effluents
Global aquaculture has been growing very fast in recent decades due to several factors, including: population growth, demand for low calorie protein and especially the reduction of natural fish stocks. Brazil has enormous potential to become a world leader in fisheries production in captivity. However, the development of aquaculture in Brazil must be conduct

4. Estudo do processo de cristalização de sacarose a partir de soluções provenientes de cana-de-açúcar por resfriamento controlado
Today, Brazil is the major producer and exporter of sugar in the world. In the last harvest 2008/2009, 31.5 millions tons were produced, of which 60% were exported providing a 40% of international market share. However, sugar is a product that has commercial difficulties, due to the hard restrictions, such as rates, subsidizes and technical barriers like the

5. Simulação do processo de desasfaltação de petroleo pesado para obtenção de asfaltenos e oleo lubrificante / Simulation of a heavy oil deasphalting process to obtain asphaltenes and lube oil
Petroleum deasphalting is one of the major primary processes in crude oil refining. The study of deasphalting has gained considerable attention in the last few decades due to the increase in heavy crude oil reserves. In Brazil, the majority of the explored reserves produce heavy oils. The increasing reduction in the processing of light oils, added to the inc

6. Characterization and treatment of sludge originated from septic tanks / Caracterização e pré-tratamento de lodo de fossas e de tanques sépticos
Septic tanks are small structures used for partial treatment of wastewater produced from urban and rural areas. It utilization is justify mainly by simplicity of construction and for being a technology that requires low operational dedication. Although it is a technology vastly used in Brazil, there is not much information about the characteristics of the wa

8. Projeto, desenvolvimento, otimização e scale-up de um leito fluidizado para classificação de fosfato bicálcico microgranulado
Brazil holds second place in world production of dicalcium phosphate, which represents the main source of phosphorus for complementing the mineral salt that makes up the daily feed for cattle, hogs and fowls. Considering the fact that the increase in consumption of phosphates due to the increased annual consumption of meat by the world population, developmen

9. Simulação, projeto e construção de uma unidade piloto multi-proposito para pirolise de residuos
Pyrolysis, one of many solid waste chemical conversion processes, has been receiving a special atenttion from engineers, researches and environment specialists. The pyrolysis has been tested in many pilot plants, and some industrial plants are operated with success. Heating in a controled atmosphere absenced of oxygen, an organic portion of waste materials c

10. Conversion of a deasphalting unit for use in the process of supercritical solvent recovery
In order to reduce energy consumption and to increase deasphalted oil yield, an old PETROBRAS deasphalting unit was converted for use in the process of supercritical solvent recovery. In-plant and pilot tests were performed to determine the ideal solvent-to-oil ratio. The optimum conditions for separation of the supercritical solvent from the solvent-plus-oi

11. Development of a Laboratory-Scale Leaching Plant for Metal Extraction from Fly Ash by Thiobacillus Strains
Semicontinuous biohydrometallurgical processing of fly ash from municipal waste incineration was performed in a laboratory-scale leaching plant (LSLP) by using a mixed culture of Thiobacillus thiooxidans and Thiobacillus ferrooxidans. The LSLP consisted of three serially connected reaction vessels, reservoirs for a fly ash suspension and a bacterial stock cu
