Acetaldehyde is a typical toxic substance of the petrochemical industry. Dissolved organic carbon (DOC) plays an important role in wastewater treatment. Therefore, molecular weight, hydrophilicity, and chemical composition DOC acetaldehyde were evaluated. First, weight (MW) distribution was investigated; results showed that mainly composed components with MW less than 1 kDa, possessed higher pr...

The main object of this study was to compare the natural and synthetic( NaA and NaM) zeolites as absorbents in removing emulsified and dissolved traces of organic compounds, which appear in the wastewater of  power plants, refinery and petrochemical complexes.  The specific objectives of the work was: a) to select the best species that have the highest amount of absorption; b) to measure th...

The paper describes an approach to predicting gas explosion loads and response which has been developed for offshore installations and which only recently has been adapted to onshore petrochemical facilities. The paper consists of three parts: Part 1: An overview of vapour cloud explosion hazards in petrochemical onshore facilities and a discussion of modeling approaches. Part 2: A probabilisti...

Erratum: “Radionuclides in Fracking Wastewater: Managing a Toxic Blend” The Focus article “Radionuclides in Fracking Wastewater: Managing a Toxic Blend” [Environ Health Perspect 122:A50–A55 (2014); http://dx.doi.org/10.1289/ehp.122-A50] incorrectly stated that Pennsylvania requires pit liners for temporary impoundments and disposal to have a minimum thickness of 30 mm. The correct minimum thick...

Abstract: Chemical storage tank leakage in petrochemical wharf is a serious economic, environmental and safety problem. Risk assessment is an effective way to identify chemical storage tank hazards and provides a guide for accident prevention in petrochemical wharf enterprises. Based on the characteristics of chemical storage tank zone, this paper proposes a real-time relative risk assessment m...

Natural dyes have been used from ancient times for multiple purposes, most importantly in the field of textile dying. The increasing demand and excessive costs natural dye extraction engendered discovery synthetic petrochemical compounds. Nowadays, they are dominating market, with nearly 8 × 105 tons produced per year due to their wide range color pigments consistent coloration. Textile industr...

In this work, a multiperiod MINLP model is proposed for the supply chain optimization of a petrochemical complex. Nonlinear, semi-rigorous models have been included for main plants in the site, allowing the determination of process operating conditions and product properties. Intermediate and final product storage and shipping are considered. Binary variables are associated to intermittent prod...
