The development of high-sulfur gas fields, also known as sour gas field, is faced with a series of safety control and emergency management problems. The GIS-based emergency response system is placed high expectations under the consideration of high pressure, high content, complex terrain and highly density population in Sichuan Basin, southwest China. The most researches on high hydrogen sulphide gas dispersion simulation and evaluation are used for environmental impact assessment (EIA) or emergency preparedness planning. This paper introduces a real-time GIS platform for high-sulfur gas emergency response. Combining with real-time data from the leak detection systems and the meteorological monitoring stations, GIS platform provides the functions of simulating, evaluating and displaying of the different spatial-temporal toxic gas distribution patterns and evaluation results. This paper firstly proposes the architecture of Emergency Response/Management System, secondly explains EPA's Gaussian dispersion model CALPUFF simulation workflow under high complex terrain and real-time data, thirdly explains the emergency workflow and spatial analysis functions of computing the accident influencing areas, population and the optimal evacuation routes. Finally, a well blow scenarios is used for verify the system. The study shows that GIS platform which integrates the real-time data and CALPUFF models will be one of the essential operational platforms for high-sulfur gas fields emergency management.

“…Such an approach can be used to assess the environmental safety of new industrial technologies [10], [11] along with an assessment of their economic efficiency [12]. Mathematical modelling of the physical processes of release and dispersion of harmful impurities in the surface layer of the atmosphere allows us to predict the fields of mass concentration of TC [13], to determine the inhalation toxidosis and the probability of damage to the maintenance personnel [14]- [16].…”

The purpose of the work is to assess the degree of inhalation damage of a person exposed to the toxic cloud of liquefied gas evaporation from a spill spot of various shapes. The mathematical model of liquefied gas spill evaporation which arose as a result of accidental destruction of the storage capacity and further dispersion of the gas impurity in the atmosphere surface layer was developed. The computational technology for determining the fields of conditional probability of human inhalation damage by a toxic gas based on a probit analysis is developed. The mathematical model takes into account the flow compressibility, complex terrain, three-dimensional nature of the dispersion process, and the presence of toxic liquid substance evaporation from the arbitrary spill spot with varying intensity. The model allows obtaining space-time distributions of the toxic gas relative mass concentration and inhaled toxidosis which is necessary to determine the fields of the human damage probability based on the probit analysis. For different ellipticity of the hydrogen cyanide spill elliptical spot the fields of probability of human mortal damage are obtained and the influence of spot ellipticity on the scale of the consequences of an accident of this type is analysed. The developed technology allows carrying out automated analysis and forecasting in the time and space of the damage probability of a person exposed to the toxic gas as an indicator of the safety of the technogenic object.

“…In order to mitigate the damage of a chemical accident, a great deal of research has focused on the statistical analysis of accident risk [ 2 ] and executive emergency response plans [ 4 , 5 ]. With the development of environmental numeric simulation models [ 6 , 7 , 8 , 9 ] and model integration techniques [ 10 , 11 ], many Decision Support Systems (DSSs) have been established to help manage chemical hazards [ 12 , 13 , 14 , 15 , 16 , 17 ]. A recent survey found that most DSS are based on quantitative risk assessments of potential accident sources and used to predict and prevent major accidents.…”

“…However, limited by the technical capacity and design idea, these DSSs always have shortcomings in some respects. First the majority of DSSs can only handle specific types of accidents, mostly hazard release and diffusion [ 13 , 15 , 16 ]. Few take explosion and conflagration into consideration, but due to the serial simulation strategy, cannot realize the multi-type simulation simultaneously [ 14 , 17 ].…”

“…Second, other DSSs have utilized real-time data processing (including meteorology data and accident source information) [ 6 , 13 ], but cannot present real-time simulation results. Third, the system architecture for DSS is mostly in the client/server mode [ 13 , 14 , 15 , 16 , 18 ]. This category of system architecture is easy to design and implement, although the software modification for system function amendments, at client and servers ends, are very involved.…”

The chemical industry poses a potential security risk to factory personnel and neighboring residents. In order to mitigate prospective damage, a synthetic method must be developed for an emergency response. With the development of environmental numeric simulation models, model integration methods, and modern information technology, many Decision Support Systems (DSSs) have been established. However, existing systems still have limitations, in terms of synthetic simulation and network interoperation. In order to resolve these limitations, the matured simulation model for chemical accidents was integrated into the WEB Geographic Information System (WEBGIS) platform. The complete workflow of the emergency response, including raw data (meteorology information, and accident information) management, numeric simulation of different kinds of accidents, environmental impact assessments, and representation of the simulation results were achieved. This allowed comprehensive and real-time simulation of acute accidents in the chemical industry. The main contribution of this paper is that an organizational mechanism of the model set, based on the accident type and pollutant substance; a scheduling mechanism for the parallel processing of multi-accident-type, multi-accident-substance, and multi-simulation-model; and finally a presentation method for scalar and vector data on the web browser on the integration of a WEB Geographic Information System (WEBGIS) platform. The outcomes demonstrated that this method could provide effective support for deciding emergency responses of acute chemical accidents.
