background: the refining process generates large volumes of wastewater containing a variety of chemical contaminants. the use of natural substitutes in treating wastewater which have fewer harmful effects is considered an effective step towards protecting the environment and sustaining the development of these industries. this study focused on the use of moringa oleifera and alum at the wastewa...

Organic toxic compounds such as polycyclic aromatic hydrocarbons, phenolic are a global environmental concern they cause inflammation and skin cancer. As you know there two types of anthropogenic sources hydrocarbons: petrogenic pyrogenic sources. Petrogenic include crude oil petroleum-derived hydrocarbon compounds. Pyrogenic formed result incomplete combustion organic substances oil, wood, coa...

This paper evaluates the influence of crude oil (vacuum residue) properties, processing fluid catalytic cracking slurry oil, and recycle hydrocracked vacuum residue diluted with heavy cycle operating conditions H-Oil hydrocracking on quality liquid products. 36 cases operation a commercial H-Oil® ebullated bed hydrocracker were studied at different feed composition, conditions. Intercriteria an...

Background. Sustainability and safety of production processes are a priority for organizations operating in potentially hazardous areas service. To promote safe work style maintain the stability processes, concept culture (SC) is actively used. The problem involving employees to issues brings up aspects engagement, motivation values.

Palm fatty acid distillate (PFAD) and methyl ester (FAME) are used by P. aeruginosa PAO1 to produce rhamnolipid biosurfactant. The process of fermentation producing biosurfactant was structured in a 2 L bioreactor using 2% PFAD FAME as carbon sources minimal medium with nitrogen concentration 1 g L?1. Mass spectrometry results show the crude produced predominantly monorhamnolipid (Rha-C10-C10) ...
