The main objective of this study is to define an emergency response team's location in a specific area based on the risk of refinery's plants. The Centre of Gravity and Hakini network methodologies are both used to define the team's location in a network based on index values and distance between locations. These methodologies are different with respect to one basic concept concerning the possibility of defining critical locations in the network in the first case and boundaries on the second case. The index in this case will be the frequency of hazardous events in each plant located in the network. The two methodologies will be implemented and the results will be assessed. A sensitivity analysis will be carried out, looking at specific elements such as alternative routes and population dislocation in case of accidents. Furthermore, the real historical data and usual data used in Brazil for hazardous events will be assessed to check the influence on the final results. A third methodology, the Monte Carlo simulation, will be carried out to check the emergency team's availability, safety reliability and number of expected unwanted events to support the final decisions and verify if the best location takes some influence in emergency attendance efficiency. The refinery case study will be carried out to define emergency response team location in a Brazilian refinery.

Case Study - Groundwater: Locating Water Wells
South Sudan: 4000 L/min water wellDate: February 25, 2015Site: Yeri Mozo Village, South Sudan, AfricaEquipment: SuperStingR8 WiFi, SwitchBox56 and passive cables spaced at 5m.Software: EarthImager2D with a finite element inversion model of dipole-dipole array data.Results: Resistivity imaging successfully located a very high production potable water well with 4000 liter/hour static yield.
Simultaneous nitrification, denitrification and phosphorus removal (SNDPR) in a full-scale water ...
The combination of simultaneous nitrification-denitrification (SND) with enhanced biological phosphorus removal (EBPR) provides a more efficient and economically viable option for nutrient removal from municipal wastewater compared to conventional two-step nitrification-denitrification. This study analyzed the nutrients (N and P) profiles in a full-scale municipal wastewater reclamation plant (WRP) located in the tropical region, in which more than 90% of nitrogen was removed. Interestingly, average SND efficiency...
Antibiotics in groundwater under locations with high livestock density in Germany
Antibiotics are deployed in large quantities both in human and in veterinary medicine. Studies show that antibiotic residues occur in the environment (e.g. soil and surface waters). In some cases they were also detected in ground and drinking water. However, the degree of groundwater pollution by antibiotic residues from livestock farming is unknown. Therefore, the federal environment agency (UBA) supported a project that aimed to investigate near-surface groundwater samples in regions of high livestock density...
Locating Leaks for Cooling Water Systems
This article illustrates how to locate leaks on cooling water systems in loud, industrial environments like Nuclear or Coal power generating plants without digging or putting anything inside the pipeline. Infrared-Energy Pattern Analysis (IR-EPA) works on all pipeline sizes and all pipeline materials because it identifies the water outside the pipeline instead of listening for leak noises like traditional leak detection techniques. IR-EPA is safe due to its passive nature and only monitors the ground surface for...
Typical Sensor Location Considerations
The sensor mounting location within a space may be dependent on many variables. There are no specific formulas since each application will have it’s own determining factors and priorities. These include, but are not limited to: source of gas: Is the source a combustion exhaust from a vehicle or furnace or a vapour from a tank spill, pipe leak, or faulty valve? density of gas: some gases are light than air and will rise, others are heavier and will migrate toward to the floor or into a pit use of the...
