The aim of this work focuses on the study for degumming multi specie and ray liver oils obtained by fish industry trough phosphoric acid enzymes process. used as agents were Lecitase Ultra® phospholipase A1 LysoMax® Oil acyltransferase. effect phosphorous content, acidity, peroxide value, anisidine index, color density evaluated. Then, neutralization with NaOH was carried out to eliminate free ...

Residue hydrodesulfurization (RHDS) is a critical process in the petroleum refining industry for removing sulfur compounds from heavy residual oils. However, catalysts used RHDS can easily be deactivated by numerous factors, leading to reduced efficiency and economic benefits. The remanufacturing of spent useful strategy extending lifespan catalysts, reducing waste, improving sustainability. Th...

The oil refining industry is an with high requirements for process control. Nowadays, important problem the creation of concept control systems companies and enterprises. Oil one Earth's most resources. Its extraction processing have become relevant mankind. However, in modern environment, tasks extracting latest equipment, as well use cleaning minimal losses, important. This paper discusses in...

A molecule-based characterization methodology was developed for correlation and prediction of assays and properties for crude oil and petroleum fractions. From readily accessible crude oil, the assay data such as distillation curve, API gravity, and PNA contents, identifies an optimal set of chemical compositions of model hydrocarbon molecules that were designed to mimic measurable physical and...

The paper considers the problem of lean manufacturing in oil and gas industry. Oil-producing enterprises have no experience using manufacturing, but it seems to be cost-effective. Now introduction resource-saving technologies at industry, including is relevant. purpose article develop recommendations for promising directions development current state sector economy world Russian Federation has ...

Many have voiced concern about the long-term survival of coastal communities in the face of increasingly intense storms and sea level rise. In this study we select indicators of key theoretical concepts from the social-ecological resilience literature, aggregate those indicators into a resilience-capacity index, and calculate an index score for each of the 52 coastal counties of Louisiana, Texa...

Mercury pollution threatens the environment and human health across the globe. This neurotoxic substance is encountered in artisanal gold mining, coal combustion, oil and gas refining, waste incineration, chloralkali plant operation, metallurgy, and areas of agriculture in which mercury-rich fungicides are used. Thousands of tonnes of mercury are emitted annually through these activities. With ...
