Sulfur compounds are removed from petroleum by the addition of sodium hydroxide at a very high concentration. As a result, a residue called spent soda or spent caustic is generated, being extremely aggressive to the environment. In this work, the chemical properties of this residue are described in detail. The sodium hydroxide remains that have not reacted, sulfur compounds, and organic matter ...

Hazardous waste is any solid waste that either exhibits any of the ,characteristics, of hazardous waste or is a listed EPA waste. In addition, EPA Hazardous Waste Codes are also classified as acute and non-acute. P-listed codes and certain dioxin codes (F020-F023 and F026-F028) are considered to be acute, whereas the remaining codes are non-acute.

The WD-PAC and ACTF-PAC materials reflect a good gasoline and condensate oil adsorption capacity (q e , mg.g−1) from ,wastewater, with high kinetics rates within 2–4 h contact time. Kinetic adsorption was found to behave as a pseudo-second kinetic model and controlled by a diffusion mechanism with an exothermic nature.
