Previous issue date: 2013-07-29 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico / One of the waste generated during the drilling of oil wells are gravel which are impregnated
of drilling fluid. This residue consists of highly toxic chemicals, including toxic metals. This
study suggests an alternative process to the treatment of this waste, by incorporating it the
form of raw material in the ceramic matrix , and by solidification and stabilize the metals present,
Aluminum (Al), Iron (Fe), Manganese (Mn) and Zinc (Zn). The raw materials were
characterized by the techniques of X ray fluorescence (FRX), X ray diffraction (DRX), laser
granulometry (GL), thermogravimetry (TG) and differential thermal analysis (ADT). To evaluate
the percentage of gravel effect the environmental and technological properties were obtained
from formulations containing 0, 10 and 20 % by weight of gravel in the ceramic matrix.
After sintering at temperatures 1080, 1120 and 1160 ?C, the samples were tested for water
absorption, the linear shrinkage firing, voltage of rupture and solubility. The results obtained
showed that the stabilization by solidification, is a viable alternative to safe disposal of
waste drilling. Ceramics products can be used in the manufacture of solid bricks / Um dos res?duos gerados durante a perfura??o de po?os de petr?leo s?o os cascalhos
que ficam impregnados por fluido de perfura??o. Este res?duo ? composto por produtos
qu?micos de alta toxidade, entre eles os metais t?xicos. Este estudo prop?e um processo alternativo
ao tratamento deste res?duo, incorporando-o na forma de mat?ria-prima em matriz cer?mica,
e atrav?s da solidifica??o estabilizar os metais t?xicos presentes, Alum?nio (Al), Ferro
(Fe), Mangan?s (Mn) e Zinco (Zn). As mat?rias-primas foram caracterizadas por fluoresc?ncia
de raios X (FRX), difratometria de raios X (DRX), granulometria a laser (GL), termogravimetria
(TG) e an?lise t?rmica diferencial (ADT). Para avaliar o efeito do percentual de cascalho
nas propriedades tecnol?gicas e ambiental, foram obtidas formula??es contendo 0, 10 e
20 % em massa do cascalho na matriz cer?mica. Ap?s sinteriza??o ?s temperaturas de 1080,
1120 e 1160 ?C, as amostras foram submetidas a ensaios de absor??o de ?gua, retra??o linear
de queima, tens?o de ruptura ? flex?o e solubilidade. Os resultados alcan?ados mostraram que
a t?cnica de estabiliza??o por solidifica??o, ? uma alternativa vi?vel a destina??o segura do
res?duo de perfura??o. Os produtos cer?micos obtidos podem ser utilizados na fabrica??o de
tijolos maci?os e blocos cer?micos de alvenaria, em determinados percentuais e temperaturas
de queima descritas neste trabalho / 2020-01-01
