Statistical analysis was used to investigate the effects of differen...
Probabilistic risk assessment through fault tree analysis is an effective tool to estimate the probability of hazardous event occurrence in chemical process industries. The probability of failure occurrence for basic events is not often available in process industries. The aim of this study was to calculate the basic event failure occurrence probab...
If shutdown scenario of burner of the sulfur recovery unit takes place, toxic release, fire, and explosion accident can easily occur. Therefore, it is essential to assess the basic causes of burner shutdown scenario. Fault Tree Analysis (FTA) could be used to assess the occurrence probabilities of burner shutdown scenario and its basic causes/event...
Risk analysis with fault tree analysis is essential for the chemical process industries to successfully prevent hazardous scenarios. Unfortunately, most of the process risk analysis studies based on expert judgment suffer from epistemic uncertainty problem. Fuzzy sets theory uses fuzzy membership functions to treat the vagueness and imprecision in...
Titanium dioxide nanoparticles were immobilized on granular activated carbon (GAC) as a porous and low-density support for photocatalytic degradation of furfural.

In the present research, electrocoagulation, ultrasonic, and simultaneous application of both methods were investigated to remove humic acid (HA) from wastewater. For the electrocoagulation method, the effects of five combinations of platinum, graphite, and aluminum electrodes, pH, time, voltage, temperature, and concentration of electrolyte on rem...
In the recent decades oil spills in the aquatic environments are one of the major sources of environmental pollutions, which are steadily growing with the increase in oil consumption. Adsorption is a rapid and cost effective process to minimize the environmental impacts of oil spills and cleanup these pollutants. In this work, the crude oil sorptio...
The performance of the aluminosilicate mesostructure (MSU-S) and its modified forms with phosphotungstic acid (HPW) and nickel oxide-HPW (NiO-HPW) for desulfurization and denitrogenation of model diesel fuels were studied. According to the results of characteristic tests (N2 adsorption-desorption, XRD, SEM, and NH3-TPD), HPW incorporation causes hi...
