Contamination of the water bodies occurs from different sources including oil refineries. Oil refinery effluent contains different chemicals at different concentrations including ammonia, sulphides, phenol, hydrocarbons and heavy metals. Monitoring the impact of pollutants on aquatic life forms is challenging due to the differential sensitivities of organisms to a given pollutant, and the inabi...

This study examines the GHG emissions associated with producing bio-hydrocarbons via fast pyrolysis of Miscanthus. The feedstock is then upgraded to bio-oil products via hydroprocessing and zeolite cracking. Inventory data for this study were obtained from current commercial cultivation practices of Miscanthus in the UK and state-of-the-art process models developed in Aspen Plus . The system bo...

Petroleum industries are large water consumers and generate a lot of wastewater at various stages industrial operations. Wastewater from the petroleum contain recalcitrant pollutants such as hydrocarbons that present in high concentrations, dissolved solids sulfur compounds can pose potential environmental threat. Bioelectrochemical systems (BESs) known to be sustainable processes treat kinds w...

For co-processing of bio-oil and conventional fossil feed in existing refinery fluid catalytic cracking (FCC) units, little attention has been paid to the increased aromatics basic nitrogen content associated with introduction how it affects FCC performance. In this contribution, effect blending two bio-oils obtained from different treatment wheat-straw pyrolysis vapors atmospheric residue was ...

Bio-oil produced from the hydrothermal liquefaction (HTL) of biomass is unstable and cannot be transported over long distances to a refinery for upgrading transportation fuel. This study examined effect solvent on stability bio-oils derived HTL sugarcane bagasse. The accelerated aging test (0–8 days at 80 °C) was used assess these oils with aid indicators such as water content, molecular weight...

The operational stability and continuity are key production characteristics of actual refinery processing units, which plays important role to safe and efficient production. While few literatures have given a sufficient and comprehensive expression of such characteristics. In view of the problem, this paper discussed refinery operations optimization based on operational stability and continuity...

The fisheries sector is one of the most ancient and important sectors in world plays a significant role providing nutrition socio-economic development country. fish processing industry produces huge quantities wastewater, encompassing amounts contaminants form soluble, colloidal, particulate matters. disposal shellfish waste serious issue, effluents discharged from seafood-processing plants con...

The accuracy of using linear models for crude distillation unit (CDU), fluidize-bed catalytic cracker (FCC) and product blending in refinery planning has been debated for decades. Inaccuracy caused by nonrigorous linear models may reduce the overall profitability or sacrifice product quality. On the other hand, using rigorous process models for refinery planning imposes unnecessary complication...
