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.
The bacterial strain TR3.2, representing a novel deeply branching lineage within the Gammaproteobacteria, was isolated and its genome sequenced. This isolate is the first cultivated representative of the previously described "Pyrene Group 2" (PG2) and represents a variety of environmental sequences primarily associated with petrochemical contamination and aromatic hydrocarbon degradation.
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...
