This is a case study of accidents occurring in a petrochemical plant located in South Eastern Brazil. It was based on comprehensive interviews with engineers and workers concerning major accidents. Information collected during the interviews highlighted the contrasts in how management and workers interpret industrial accidents. Some implications for actions were discussed.
B ulk petrochemical manufacturing is a highly competitive global industry. When margins are tight, manufacturers seek ways to optimize performance and to reduce costs while maximizing yields and revenue. Optimization options include alternative feeds, plant/process revamps and improved operations to achieve better separation and yields to lower energy consumption, to minimize product loss and t...
OBJECTIVES This study aimed to evaluate the relationship between residential district of people, such as power plant, steel-mill and petrochemical industries, and health-related quality of life (HRQoL). METHODS Using a cross-sectional study design, we randomly recruited participants for our study from industrial areas (thermoelectric power plant, steel-mill, petrochemical industry) and rural ...
We evaluated glutathione transferase (GST) activities and the levels of glutathionylated hemoglobin in the RBC of 42 workers exposed to 1,3-butadiene in a petrochemical plant, using 43 workers not exposed to 1,3-butadiene and 82 foresters as internal and external controls, respectively. Median 1,3-butadiene exposure levels were 1.5, 0.4, and 0.1 microg/m3 in 1,3-butadiene-exposed workers, in wo...
[1] Airborne formaldehyde (CH2O) measurements were made by tunable diode laser absorption spectroscopy (TDLAS) at high time resolution (1 and 10 s) and precision (±400 and ±120 parts per trillion by volume (pptv) (2s), respectively) during the Texas Air Quality Study (TexAQS) 2000. Measurement accuracy was corroborated by in-flight calibrations and zeros and by overflight comparison with a grou...
The course of 20-year studies on the health of the population of Ptock and its neighbourhood has been discussed as regards environmental pollution generated by refinery-petrochemical plant. Analysis of environmental factors and general principles of health-promoting phenomena were of particular concern. This paper demonstrates an increase in options of environmental factors in studies on health...
Petrochemical plants are increasingly faced with the need to upgrade their control centers to support the installation of more advanced control systems and to better protect operations personnel in the event of catastrophe. Plants often take advantage of this opportunity to consolidate existing control rooms into a central facility, in hopes of improving plant-wide communications, increasing op...
Fugitive emissions are an important aspect in running a chemical or petrochemical plant. Apart from their environmental impacts, fugitive emissions are responsible for loss of medium during the production process. Due to this plant efficiency is reduced and a higher capital expenditure is required. Three common types of sealing systems are compared: compression packings, mechanical seals and ma...
