Introduction FCC decant oil is the primary feedstock to delayed coker to produce needle coke, a premium carbon precursor to synthetic graphite electrodes. Mesophase development during coking, determines the graphitizability of the needle coke product. Mesophase development, in turn, depends on the molecular composition of the feedstocks [1,2]. In a commercial delayed coking unit, liquid-phase c...

Stormwater run-off from for example industrial areas as well as roads with heavy traffic may contain considerable amounts of pollutants. Run-off from these areas may require special treatment to fully comply with existing environmental regulations and safeguard the receiving water bodies. In this study, flocculation and membrane filtration are tested to evaluate their efficacy in removing heavy...

Mangrove sediment harbors a unique microbiome and is a hospitable environment for a diverse group of bacteria capable of oil biodegradation. Our goal was to understand bacterial community dynamics from mangrove sediments contaminated with heavy-oil and to evaluate patterns potentially associated with oil biodegradation is such environments. We tested the previously proposed hypothesis of a two-...

The simultaneous extraction of oil and sand during the cold production of heavy oil generates high porosity channels termed “wormholes”. Wormholes grow in a 3D radial pattern within a certain layer of net pay zones, resulting in the development of a high permeability network in the reservoir, boosting oil recovery. Meanwhile, the development of wormholes causes reservoir pressure to fall below ...

The effect of spent engine oil (SEO) on soil properties and growth of maize (Zea mays L.) was investigated. Five treatments (0.0, 0.2, 0.4, 0.6 and 0.8 l/kg) of the spent oil were applied to soil in perforated poly bags with maize stands at four weeks after sowing. Soil analysis showed that SEO had no effect on both the pH and texture of the soil. Organic C, N and Mg in the contaminated soils i...

During any marine oil spill, floating oil slicks that reach shorelines threaten a wide array of coastal habitats. To assess the presence of oil near shorelines during the Deepwater Horizon (DWH) oil spill, we scanned the library of Synthetic Aperture Radar (SAR) imagery collected during the event to determine which images intersected shorelines and appeared to contain oil. In total, 715 SAR ima...

Measures for assessing the environmental impact and long-term sustainability will become an increasingly important requirement in industrial project management. The concept of sustainability influences all aspects of a project, from its earliest phases: development procedures, design of facilities and infrastructure, operation of the industrial facility, and economics. Project management resear...
