Previous issue date: 2004-09-02 / The production of petroleum is frequently accomplished with great volumes of water, that it is carried of the underground with the oil. It is a challenge of the present century the development of technologies that allow the use of waste water for purposes that consume great amounts of water and don't demand as rigid as the one of the drinking water requirements. The solar distillation has been configuring as an alternative of clean technology for desalination of brine and saline. Besides causing the minimum possible damage to the environment, it takes advantage of an abundant and free energy source: the solar energy. That study aims to develop a Solar Distillator for treatment of the produced water of the oil wells, to obtain an efluent to use in agriculture and vapor generation. The methodology for collection, conservation and analysis of the physical-chemical parameters obeyed the norms in APHA (1995). The sampling was of the composed type. Experiments were accomplished in the solar distillation pilot and simulation in thermostatic bathing. The operation was in batch system and for periods of 4, 6 and 12 h. The developed Distillator is of the type simple effect of two waters. It was still tested two inclination angles for covering; 20? and 45?. The Distillator presented minimum of 2,85 L/m2d revenues and maximum of 7,14 L/m2d. The removals of salts were great than 98%. The removal of TOC in the simulation was great than 90%. In agreement with the data of energy and mass balance, it was verified that the developed solar Distillator presented compatible revenues with those found in literature for similar types. It can be inferred that the obtained distilled water assists to the requirements CONAMA in almost all the points and could be used for irrigation of cultures such as cotton and mamona. As the distilled water has characteristics of fresh water it can be used in the generation of vapor / A produ??o de petr?leo ? realizada freq?entemente com grandes volumes de ?gua, que ? carreada do subsolo junto com o ?leo. ? desafio do presente s?culo o desenvolvimento de tecnologias que possibilitem ou uso ou reuso de efluentes para outros fins. A destila??o solar ? uma alternativa de tecnologia limpa para dessaliniza??o de ?guas salobras e salinas. Esse estudo visa desenvolver um Destilador Solar para tratamento da ?gua de produ??o de petr?leo, com vistas a se obter um efluente pass?vel de utiliza??o na agricultura e gera??o de vapor. A metodologia para conserva??o e an?lise dos par?metros f?sico-qu?micos obedeceu preconiza??o do APHA (1995). A amostragem foi do tipo composta. Foram realizados experimentos no destilador solar piloto e simula??o em banho termost?tico. A opera??o foi em sistema de batelada e por per?odos de 4, 6 e 12 h. O destilador desenvolvido ? do tipo simples efeito de duas ?guas. Testou-se ainda dois ?ngulos de inclina??o para cobertura; 20? e 45?. O destilador apresentou rendimentos m?nimo de 2,50 L/m2d e m?ximo de 7,5 L/m2d. As remo??es de sais foram superiores a 98%. A remo??o de TOC na simula??o foi superior a 90%. De acordo com os dados dos balan?os energ?tico e de massa, verificou-se que o destilador solar desenvolvido apresentou rendimentos compat?veis com os encontrados na literatura para seus similares. Enfatiza-se que o isolamento utilizado n?o estava nas condi??es de otimiza??o, logo, esse rendimento pode ser melhorado. Pode-se inferir que a ?gua destilada obtida atende aos requisitos CONAMA em quase todos os pontos, podendo ser utilizada, com ressalvas, na irriga??o de culturas n?o comest?veis como o algod?o e a mamona. Como a ?gua destilada tem caracter?sticas de ?gua doce pode ser utilizada na gera??o de vapor
