background: in process industries, production, storage, transportation, usage and disposal of chemicals are inherently dangerous and the risk of catastrophic accident occurrence is potentially high. to improve safety level in these industries, establishment of process safety management (psm) system is considered as the most effective measures. this study was conducted to determine the degree of...

BACKGROUND Petrochemical industries have been identified as important sources of emissions of chemical substances, and adverse health outcomes have been reported for residents who live nearby. The purpose of the current study was to examine the adverse effects of petrochemical industrialization in Taiwan on the life expectancy and personal income of people living in nearby communities. METHOD...

Microalgae are capable producers of food, feed supplement, chemicals, and biofuels. Marine microalgae and cyanobacteria are rich in several chemical compounds therefore, they could be used in some biological applications related with health benefits. Through microalgae, a wide variety of compounds such as polyphenols, polyunsaturated fatty acids (PUFA), or phytosterols can be obtained. However,...

Mining and deforestation in the early 20th century, the development of petrochemical industries during the 1950s, and the constant weathering of natural deposits of cinabrium (HgS) have made Golfo Triste, Venezuela, a region impacted by mercury (Hg). We studied the chronology of Hg in coral skeletons of Siderastrea siderea (1 colony, 1900-1996) and Montastraea faveolata (2 colonies, 1930-1999) ...

background heat, chemical and organic pollution are three types of environmental pollution, caused by refinery and petrochemical industries. problems caused by hear and chemical pollutants are currently resolved to some extent but organic pollution such as poly aromatic hydrocarbons (pahs) are still considered as important problems of industry and environment. objectives a laboratory study was ...

— Seven important variables having profound impact on the ability of a mixing tank to suspend particles have been investigated using computational fluid dynamics (CFD) technology. The results obtained from this study can be applied across a broad range of industries such as the chemical, biochemical, petrochemical and mineral processing industries. Finally, a design template incorporating the o...

The industrial wastewater treatment is gaining more and more importance with the rapidly increasing need for expansion of existing plants and erection of new plants to cater the needs of chemical, pharmaceutical and petrochemical products and intermediates. The treatment of the wastewater is key to the sustainable and acceptable industrial growth. Petroleum industries and refineries are importa...

the establishment of good process safety management (psm) is widely considered as the most effective means of improving safety levels in process industries. this study was conducted to evaluate the feasibility of establishing and implementing psm requirements based on occupational health and safety assessment series 18001 standards (ohsas 18001) and health, safety and environment management sys...
