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 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...

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...

Production planning is a very important step in managing the operation of a single refinery and their complexes. Despite its significance, few contributions have been found in literature and the existing ones rely on linear models. Pinto et al. (Comp. Chem. Engng. 24, 2259-2276, 2000), presented a superstructure that represents a general topology and allows the implementation of nonlinear proce...

BACKGROUND Occupational and environmental exposure to petroleum refinery products poses a great threat to human health. This study aimed to assess the lung function and Fractional Exhaled Nitric Oxide (FeNO) among petroleum refinery workers. METHODS In this cross-sectional study, 112 participants (56 petroleum refinery workers with mean age 35.20 ± 1.62 years, and 56 age, weight, height, ethn...

Through a variety of material screening experiments, Al was selected as the added metal and constituted a multiple micro-electrolysis system of Fe/C/Al. The metal proportion of alloy-structured filler was also analyzed with the best Fe/C/Al ratio of 3:1:1. The regular Fe/C/Al multiple micro-electrolysis fillers were prepared using a high-temperature anaerobic roasting method. The optimum condit...

The health risk resulting from benzene exposure in petroleum refineries was calculated using data from the scientific literature from various countries throughout the world. The exposure data was collated into four scenarios from petroleum refinery environments and plotted as cumulative probability distributions (CPD) plots. Health risk was evaluated for each scenario using the Hazard Quotient ...

BACKGROUND Occupational exposure to nickel (Ni) is associated with an increased risk of lung and nasal cancers. Ni compounds exhibit weak mutagenic activity, alter the cell's epigenetic homeostasis, and activate signaling pathways. However, changes in gene expression associated with Ni exposure have only been investigated in vitro. This study was conducted in a Chinese population to determine w...
