This study examined the impact strategy, core competence, and involvement of HR executives in strategic decision making on the refinery managers' evaluation of the effectiveness of HR and refinery performance among 86 U.S. petro-chemical refineries. Survey results indicated that higher involvement of HR in organizational strategy was strongly related to perceptions of HR effectiveness, and that...

Caustic scrubbing is a technology that has been used for the removal of H2S and other acid species from gases in different industries for many years. Improvements in design and control strategies, favorable prices for caustic compared with other non-regenerable H2S scavenging chemicals, and the potential for sales value for the NaHS (sodium bisulfide) product have made caustic scrubbing an econ...

The conversion of biomass into fuel under typical refinery conditions is a promising solution to decrease carbon footprint. Herein we convert representative compound new bio-petroleum, DX (1,2:3,5-di-O-isopropylidene-α-D-xylofuranose) mixture with n-hexane. Firstly fresh zeolites (Beta, ZSM-5 and USY) were explored. Beta zeolite showed high performance in converting hydrocarbons. Thus it was fu...

The continued reliance on non-renewable fossil resources has led to serious environmental issues. In light of these concerns, the transition from sources more sustainable ones have been explored, as exemplified by production bio-based lactic acid via lignocellulosic biomass bio-refinery process. Malaysia, second-largest producer palm oil in world, generates abundant, cheap, and underutilized fo...

The accumulative levels of SO2 in soil and plant's leaves around an oil refinery were monitored. Four different sites around the refinery area were chosen; west, south east, north east and the northern side. The refinery southern side was not accessible. In addition to the soil samples, leaves samples of the dominant plants species Myoporum pictum were randomly collected from all sites. Highly ...

1 Data 1.1 U.S. Refineries 1.1.1 Sources of data I match and compile three data sets on characteristics and imports of U.S. refineries collected by the U.S. Energy Information Administration (EIA): (i) capacity of distillation unit and upgrading units (parts 6-7 of form EIA-820: annual refinery report); (ii) imports of crude oil, (form EIA-814: monthly imports report) (iii) domestic purchases o...

environmental pollution consists of different types of pollutants in air, soil, and water. due to the fact that plants can respond to environmental pollution, they can be used as bio-indicators for environmental monitoring. air pollution in areas with oil and gas refineries nearby is an important problem. this study aims to survey the effects of gas refinery air pollutants on conocarpus erectus...

Conventional biological treatment process is not very efficient for the treatment of petroleum refinery wastewater (PRW) that contains high-concentration of organic contaminants. Prior to biological treatment, an additional pretreatment process for PRW is required for the effluent to meet the discharge standards. While re-circulated bio-filter (RBF) has been applied as a pretreatment process in...

We introduce Refinery, an open source platform for exploring large text document collections with topic models. Refinery is a standalone web application driven by a graphical interface, so it is usable by those without machine learning or programming expertise. Users can interactively organize articles by topic and also refine this organization with phrase-level analysis. Under the hood, we tra...

In this paper, a modeling tool for risk assessment analysis of the movement of hydrocarbon contaminants in the vadose zone and mass flux of contamination release into the groundwater table was developed. Also, advection-diffusion-reaction equations in combination with a three-phase equilibrium state between trapped air, soil humidity, and solid particles of unsaturated soil matrix were numerica...
