This paper addresses the solution of a two-stage stochastic programming model for a supply chain investment planning problem applied to the petroleum products supply chain. In this context, we present the development of acceleration techniques for the stochastic Benders decomposition that aim to strengthen the cuts generated, as well as to improve the quality of the solutions obtained during th...

In this paper the relationships between crude oil and refined product prices are investigated in a multivariate framework. This allows us to test several (partly competing) assumptions of earlier studies. In particular, we find that the crude oil price is weakly exogenous and that the spread is constant in some but not all relationships. Moreover, the multivariate analysis shows that the link b...

Use of defoaming agents in the pulp and paper industry has evolved over time from use of simple petroleum based products such as kerosene to the state of the art free rinsing silicone emulsions offered by StarChem, LLC. The introduction of new processes and equipment along with the advancement of the defoamer chemistries employed has necessitated different application strategies to maximize pro...

Fuel ethanol is one of the technology success stories of the 21 century. In less than one third of a century, it has gone from being a material produced rather inefficiently in small quantities to a major commercial product. This success can be attributed not only to the fact that ethanol is a renewable fuel and replaces imported oil, but also because it is capable of competing with petroleum b...

In the presented research we have tested the application of photo ionization detector of ECOPROBE 5 analyzer to monitoring of low concentrations of petroleum products in water. Petroleum products are organic pollutants that are present in wastewater most frequently, which is caused by their broad applications and frequent incidents. Emergency leakage of petroleum and its products is predominant...

Renewable Algal Energy, LLC (Kingsport, Tenn.) Algal Biodiesel via Innovative Harvesting and Aquaculture Systems Renewable Algal Energy LLC, will leverage its experience in algal aquaculture, harvesting, and extraction, to demonstrate at small commercial-scale, improved, low cost, energy-efficient methods for harvesting and dewatering algae that contribute to an algal oil product that is cost-c...

Accepted: 29/12/2014 Abstract Polycyclic Aromatic Hydrocarbons (PAHs) are ubiquitous environmental contaminants and found almost everywhere. Most of PAHs are formed during the incomplete combustion of organic matter such as wood, petroleum product, coal and tar. These chemicals are biologically active and pose a risk for human health because of their potentially toxicity such as carcinogenicity...
