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.

NEC Classifications and Divisions for Hazardous Locations
Electrical equipment in hazardous (classified) locations present a serious threat for workers due to the existence of explosive dust and vapors. Examples of such facilities range from grain mills and gasoline stations to aircraft hangars and chemical manufacturing plants. To prevent devastating explosions that may occur from the ignition of combustible particles in the atmosphere, the National Electric Code (NEC) published guidelines on the proper classification of hazardous locations. Classes, Divisions and...
Hazardous Location LEDs in Chemical Manufacturing Facilities
Employees inside chemical manufacturing plants are exposed to some of the most unforgiving work conditions in the industrial sector. This is because in such environments, workers are exposed to extreme temperatures, dust, volatile chemicals and invisible, explosive gases. Common protection methods against explosive risks include containment, segregation and prevention. Out of all the options, explosive containment is the only method that allows an explosion to take place, in a confined and safe manner through...
Case study - Remote location requires minimum concept
A leading power supply provider in Austria took on the project of monitoring water levels at a power plant in Montenegro, in two remote locations where no infrastructure is available for installation. On top of that, site visits could only occur every two months, so a device with remote data transmission capabilities was key.Because of these factors, the customer needed an easy solution for their water level monitoring. Long recording time, easy maintenance and the low effort for maintenance were the main reasons...
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...
