One or more interconnected steam power plants (SPPs) are constructed in a petrochemical complex to supply utility energy to the process. To avoid large economic penalties or process shutdowns, these SPPs should be flexible and reliable enough to meet the process energy requirement under varying conditions. Unexpected utility equipment failure is inevitable and difficult to be predicted. Most of...

heat stress is well recognized among the hazardous physical agents that might be present during work. this study aims to compare wbgt index at acclimated and unacclimated people to permissible threshold limit value and study the differences between physiological parameters at them. twenty one healthy men were participated in the study. all of the subjects were monitored in two different weather...

abstract to study the effects of sewage sludge on tomato seedling growth, a series of pot experiments, each pot containing 17 kg soil, were conducted in a randomized complete design with eight replications. treatments used were: 5 levels of sewage sludge (5, 10, 20, 30 and 40 tons/ha) and two control treatments (t1, without sewage sludge and t2, sewage sludge + complete fertilizers). analysis o...

This article aims to verify the residents’ perception difference on the environmental quality of two localities near the construction area of the Petrochemical Complex of Rio de Janeiro. Nine environmental quality aspects (water supply services, sewage and garbage collection; leisure areas; public security; health services; streets; air; rivers) were evaluated. Cross-sectional study conducted w...

The rapid development of modern society has resulted in an increased demand for energy, mainly from fossil fuels. The use of this source of energy has led to the accumulation of carbon dioxide (CO2) in the atmosphere. In this context, microalgae culturing may be an effective solution to reduce the CO2 concentration in the atmosphere, since these microorganisms can capture CO2 and, simultaneousl...

In Thailand, there is a growing concern regarding the possible effects of air pollution on the health of residents living near a petrochemical complex in Map Ta Phut Industrial Estate (MTPIE), Rayong Province, Thailand. We studied exposure to selected volatile organic compounds (VOCs) in Map Ta Phut and the association between residing near the petrochemical complex and respiratory ailments. We...
