Analysis of the cement clinker produced with incorporation of petroleum sludge

Abstract: Very limited researches have been conducted on the incorporation of petroleum sludge waste into cement clinker production even though this waste may contain similar components to those of clinker raw materials. In this research, petroleum sludge was integrated into cement plant as raw material to produce the cement clinker. As results, incorporation of 5% of this waste was able to produce an acceptable quality of cement. Despite the use of petroleum sludge has decreased the properties of the produced clinker, but it still fit the requirements.

Nanostructured Membranes for Water Purification

Abstract: Membrane based processes enjoy numerous industrial applications and have greatly enhanced our capabilities to restructure production processes, protect the environment and public health, and provide new technologies for water purification. The scope of membrane technology is still extending, stimulated by the developments of novel membrane materials and membranes with better properties, as well as by the decrease of capital and operation costs. Recent advances in nanomaterials empower next-generation multifunctional membrane processes with exceptional catalytic, adsorptive, optical and/or antibacterial abilities that enhance treatment cost-efficiency. This chapter reviews emerging opportunities and sustainable approaches for the design of nanostructured membranes for water purification. Potential development and implementation barriers are discussed along with research needs to overcome them for enhancing water purification.

Prédiction des tensions superficielles, facteurs acentriques et indices de corrélation des hydrocarbures purs

Abstract: 'Une nouvelle methode de contribution de groupes pour l'estimation des tensions superficielles, facteurs acentriques et indices de correlation des hydrocarbures purs a ete etablie. Les deviations absolues moyennes (average absolute deviations, AAD) enregistrees entre les valeurs tabulees et celles calculees sont de 2,5 %, 4,1 % et 1,5 % respectivement pour les tensions superficielles, les facteurs acentriques et les indices de correlation.
