The purpose of the present paper is that of researching the impact of corporate governance on financial performance, on a sample of 3 companies (Tamin Petroleum & Petrochemical Investment Co., Persian Gulf Petrochemical Industries Company and Parsian Oil and Gas Development Group), mainly from the chemical industry area, listed at Tehran Stock Exchange index, during the period 2011-2016. In thi...

Special attention to the relative advantages of the economy is the best way toward economic development in every country. Owing to its considerable natural oil and gas resources, Iran has a high potential for the development of these industries. In the value chain process of these God-given resources, a wide diversity of final downstream petrochemical products has a significant charm and scope ...

For the purpose to reveal the substance as the source of offensive odor of the fish from the sea facing petroleum and petrochemical industries, analyses have been made on the sea water, industrial wastes, offensive odor fish meat and the eels kept in the sea or industrial waste for a certain period, by means of gas chromatography, infrared, and ultraviolet absorption spectrophotometries and mas...

The profiles of major volatile organic compound (VOC) sources in petrochemical industry of the Yangtze river delta, China, were experimentally determined. Source samples were taken using summa canister near the petrochemical units. The concentrations of 72 VOC species were quantified using canister sampling and a gas chromatography–mass spectrometry system, and VOC source profiles were develope...

Urban ambient air concentrations of 39 aromatic (including benzene, toluene, and xylenes) and aliphatic volatile organic compounds (VOCs) were measured in Yokohama city, Japan. Yokohama city was selected as a case study to assess the amount of VOC released from Industrial area to characterize the ambient air quality with respect to VOC as well as to know the impact of petrochemical storage faci...

Multicentre randomised trials are complex projects with many operational uncertainties. The embedding of a formal check upon study progress and viability at a pre-specified time point (sometimes referred to as an 'internal pilot') is becoming increasingly common within multicentre pragmatic randomised trials. However, it is worth considering this practice. We argue that most, if not all, multic...

Life cycle analysis and exergy are applied to compare the production of maleic anhydride from different feedstock, both biomass- petrochemical-derived raw materials, in order evaluate sustainability alternative biorefinery processes conventional routes. The considered involve two options: gas aqueous phase furfural oxidation with oxygen (air) hydrogen peroxide as oxidants, respectively, sustain...

There are generally three broad categories of landfill-gas-to-energy (LFGTE) projects: electric power generation, medium-BTU industrial fuel; and high-BTU pipeline gas. During initial feasibility studies, landfill owners and developers should weigh the advantages of each with regard to the technology, local markets, landfill conditions, and site proximity to potential users. There has been an i...

Introduction: Industrial growth, development programs and infrastructure projects, in spite of all the advantages and benefits to humans, has been considered as the source of many hazards, risks and failures. Risk assessment is the organized and systematic method to identify hazards and risk estimation for decisions ranking, in order to reduce the risk to an acceptable extent. The aim of this s...
