Thesis (MTech (Chemical Engineering))--Peninsula Technikon, Cape Town, 2004 / Current Risk Assessment procedures for the estimation of the acute health impacts resulting from the accidental release of toxic chemicals into the atmosphere involve the definition or construction of a representative accidental release scenario and the use of one or other air quality or dispersion model to estimate ambient air concentrations and exposure durations in the vicinity of the source. Legislation such as the South African Occupational Health and Safety Act, 1993, Major Hazard Installation Regulations, United States Risk Management Plan Rule and the European Union Seveso n, to prevent and or minimize impacts of such events require owners of installations to perform a Risk Assessment if they handle hazardous substances above specified threshold quantities. Mathematical modeling has been widely used to assist with the Exposure Assessment to perform off-site worst-case release analysis. Governmental departments, agencies and local authorities increasingly (but not exclusively) rely on air pollution models for making decisions related to air quality, traffic management, urban planning, and public health. As a result, the model users' community is becoming larger and more diverse. Most of the air quality modeling work has so far been based on the "deterministic" approach of using only set input parameters and specific applications. The selected model provides estimates of averaged concentrations using specific meteorological and emission data sets.

Uma vez pensados de forma isolada das demais necessidades da empresa, tornam-se ilhas de informação. Em plena era do conhecimento, informações pontuais e ilhadas trazem inúmeros malefícios como falta de colaboração de informações interdepartamentais, falta de veracidade para tomada de decisões gerenciais, acompanhamento histórico gerencial para melhoria contínua dos processos de negócio, democratização das informações, conexão com fornecedores e clientes em tempo real. O Plano Diretor de Automação e Informática, objeto desse trabalho, utiliza-se de modelos e metodologias como forma de integração dessas informações rumo à gestão do conhecimento em tempo real e os organiza em 3 domínios: Negócios, Ciclo de Vida dos Ativos e Cadeia de Valor. Propõe colaboração certificada entre fornecedores de matéria prima, processadores (área industrial) e clientes que compram seus produtos finais. Propõe o gerenciamento da performance da organização rumo a seus objetivos e por fim, propõe que a carteira de investimentos seja orientada à melhoria contínua, chegando a Excelência Operacional (OpX). Todas essas propostas partem da utilização de tecnologias tanto de automação como de tecnologias de informática para serem integradas e governadas por um único ponto de vista oriundo do gerenciamento de portfólio da organização industrial. Devido às altas cifras desses investimentos, as soluções tanto de hardware como de software não são adquiridas todas de uma única vez, mas sim dentro de projetos e programas escalonados no tempo de vida da organização industrial. Ao conjunto desses programas e projetos, chamamos de portfólio de investimentos. E para que possam ser pensados de forma integrada em nível de sua automação e informática, o Plano Diretor deve ser trabalhado dentro da gestão do portfólio. Como resultados da aplicação desses modelos e metodologias, conseguiu-se que organizações industriais chegassem mais fácil e rápido a tomada de decisões gerenciais em benefício do Negócio, Cadeia de Valor e Ciclo de Vida de seus ativos de forma colaborativa e promovendo a melhoria contínua de sua operação e gestão através de sistemas integrados em todos os domínios da informação. Como conclusão, aspectos positivos, avanços e progressos para a ciência, ficam aqui registrados um conjunto de conhecimentos e boas práticas que poderão ser aplicados, melhorados e evoluídos pelos profissionais do setor / Abstract: Chemical Industry Companies invest large amounts of funds in order to gather and send real-time information regarding their industrial processes to their Corporative Systems developed by Information Technology departments. This procedure requires smart instruments, communication network, process controllers, distributed control systems, historical data bases, manufacturing execution systems and enterprise resource planning solutions. These efforts are made in order to implement solutions to well-localized departmental issues. Once these are thought as specific needs of the enterprise, they become isolated patches of information. In the Knowledge Era, isolated information may cause several problems, such as bad syncing of interdepartmental information, lack of veracity for the management decisions, low democratization of the information and connection between the suppliers and the clients, and lack of continuous improvement for the inefficient historical database usage. The Automation and Information Master Plan, subject of this work, uses models and methodologies to integrate and manage information in real time. It rearranges information in 3 domains: business, value chain and asset's lifecycle. It proposes certified collaboration between raw-material suppliers, product processors and clients, which consume the final product. It also proposes performance and organization management in order to achieve continuous quality improvement, i.e. establish Operational Excellence (OpX). All these proposals arise from the application of Automation and Information Technologies and are oriented by the Industrial Organization Portfolio's Management only. Due to the investments' expensiveness, the solutions regarding either software or hardware are not accomplished at once, but rather inside projects and gradual processes along the industrial organization's lifetime. This set of projects and gradual processes is named investment's portfolio. In order to accomplish the integration between automation and information, the master plan must be developed inside the portfolio's management. As a result of the application of these models and methodologies, it was possible for the industrial organizations to make faster and easier decisions regarding the wellness of their assets, value chains and assets' lifecycles. In addition, these decisions also provided continuous operational quality improvement by means of management of systems integrated with all domains of information. As a conclusion, positive aspects as well as scientific progresses are here recorded as a set of procedures that should be applied, improved and further developed by professionals of the area / Doutorado / Sistemas de Processos Quimicos e Informatica / Doutor em Engenharia Química

Indiana University-Purdue University Indianapolis (IUPUI) / This thesis will investigate the effect of extractive industries on the economy of an average Midwestern town from the mid-1800s until the conclusion of the WWII. Primary and secondary sources were studied to gain an understanding of the effect of extractive industries on the development of Midland Michigan. Due to its complete reliance on extractive industries for its economic welfare Midland suffered extreme economic upheavals. In conclusion Midland’s intensive boom and bust economy mirrors Michigan’s own rocky relationship with extractive industries.

Submitted in partial fulfillment of the requirements for the degree of Masters in Technology: Business Administration, Durban University of Technology, 2007. / Unsafe incidents are a regular occurrence in the chemical industries, which have resulted, in some cases in the catastrophic destruction to the environment and loss of life. Major global organizations have shut down after experiencing fatal unsafe incidents as in the case of Union Carbide. This organization was closed after the Bhopal incident in India, in 1984, which claimed the lives of a-bout three thousand residents (see appendix d). In this study, the safety and operational risks at a selected chemical company in Durban are researched. This study looks at the huge number of unsafe incidents in a three year period, from (2003) to year (2005), that occurred at this organization. The objective of this study is to identify the variables that contribute to the high number of unsafe incidents within the organisation. The study will focus on the relationship between staff perceptions and management's assumptions of these contributory variables. The sub-objectives of the study are: o To ascertain staff perceptions of the contributors to the incidents and unsafe working conditions; o To determine if management is accurate in their assumptions of the causes for the incidents; and o To determine relationships between staff perceptions and actual causes of the incidents. The contributors were themed in the study in the following manner: o Behaviour and attitude; e Communications; e Plant and equipment; e Training and development; o Planning and workload; o Safety aspects; and e Other related aspects. Implementing the recommendations made will assist in reducing the number of unsafe incidents and make the organization a safer place for all stakeholders. / M

The thesis deals with the analysis of spatial distinction of the chemical industry in the Czech Republic. The main aim of the thesis is to evaluate the disposition of chemical production in the Czech Republic and using the tools of spatial analysis, mainly location quotients and the Lorenz curve, to identify areas with the highest concentration of the chemical production. Further to identify areas with the greatest potential for the localization and development of the chemical production. The theoretical part of the thesis describes the economic aspects of the localization of the industry and defines the chemical industry itself in a broader context. The practical part deals with the position of the chemical industry in the Czech Republic and focuses on the territory analysis which identifies the regions with the highest concentration of the chemical industry in the Czech Republic

Environmental issues are of increasing concern to citizens, governmental personnel and corporate leaders in most countries all around the world. There is a growing consensus that conventional accounting practices simply do not provide adequate information to support decisionmaking in environmental management. Simply defined, environmental management accounting is management accounting with a focus on physical information on the flow of energy, water, products and materials as well as monetary information on environmental costs and revenues, and projects related to environmental protection. It is not a different method, but simply a mechanism of doing management accounting in an improved manner. When environmental management accounting is well designed and implement it should ensure better internal management and value-added decisionmaking. Ultimately, environmental management accounting is simply doing better comprehensive management accounting while wearing an environmental hat. This study evaluates the awareness of environmental management accounting in the chemical industry. A questionnaire was administrated to a selected group of par-ticipants. All participants in the study are employees from the chemical industry in South Africa. The selection of participants was based on their knowledge, expertise and understanding of environmental practices, challenges and problems in their respective organisations. Different functional roles from different types of chemical companies were identified to participate. The findings of this study indicated that there is a good level of awareness of environ-mental management accounting in the South African chemical industry. Most orga-nisations are applying sound environmental practices and are adopting environ-mental strategies and different tools to improve their current status. Different levels of awareness exist between different types of chemical industries and between different functional roles in the respective organisations. Operational and capital environ-mental information are disclosed and organisations do generate and record information on physical and monetary environmental management accounting. / MBA, North-West University, Potchefstroom Campus, 2015
