Introduction: Today, due to the development of technology and automation of industries, the presence of humans in working environments has  decreased. Despite this dramatic decline, the cause of more than 80 percent of the incidents in the oil and gas industry is related to human errors. The purpose of this research was to identify and evaluate the human errors of operators in control room...

Background: incidents are one of the most important causes of damages in an organization. incidents, rarely, occure of a big mistakes ,they usually occur due to chain of Most minor and less important human or series errors. May each error, Have minor consequences But with combination their effects, sets or systems are moving invariably to the serious consequences and disastrous. Therefore, this...

Radon gas concentrations and uranium-238 concentration in soil samples at the surface (depth = 15 cm) were determined for fifteen three refineries (Al-Kasak, Al-Qayarah, Baiji) using “sealed can technique”. CR-39 solid-state nuclear pathway detectors. The of radon Al-kasak refinery ranged from (1509 to 8323.2 Bq/m3) with an average (4916.1 Bq/m3), exhalation rate (1110.3 612.7 (861.5 Bq/m3). ef...

The operational stability and continuity are key production characteristics of actual refinery processing units, which plays important role to safe and efficient production. While few literatures have given a sufficient and comprehensive expression of such characteristics. In view of the problem, this paper discussed refinery operations optimization based on operational stability and continuity...

The accuracy of using linear models for crude distillation unit (CDU), fluidize-bed catalytic cracker (FCC) and product blending in refinery planning has been debated for decades. Inaccuracy caused by nonrigorous linear models may reduce the overall profitability or sacrifice product quality. On the other hand, using rigorous process models for refinery planning imposes unnecessary complication...

A 25-year-old man, a field operator in a petroleum refinery was found unconscious. He was exposed to hydrogen sulfide and presented with Glasgow Coma Score of 5, severe hypoxemia on arterial blood gas analysis, normal chest radiography, and normal blood pressure. On hospital day 7, his mental state became clear, and neurologic examination showed quadriparesis, profound spasticity, increased ten...

  Performance and capacity of sulfur recovery unit (SRU) are greatly affected by the H2S:CO2 ratio of the acid gas stream. The acid gases in Iran contain around 35 mol% H2S and 60 mol% CO2. This low concentration of H2S calls for more complex sulfur plant, larger equipments, and higher costs. Acid gas enrichment processes (AGE) is run to upgrade low quality acid gas collected from gas treating...

Preliminary studies on the performance of a laboratory scale perlite biofilter inoculated with a mixed culture taken from petrochemical refinery sludge was evaluated for gas phase styrene removal under various operating conditions. Initially, the biofilter was acclimatized for 53 days at constant loading rates (40-60 g/m.h), wherein the performance gradually improved with fluctuations in the re...
