A New Semi-Quantitative Process Safety Assessment Method and Its Application for Fluorochemical Industry
نویسندگان
چکیده
Traditional hazard and operability analysis (HAZOP) is one of the most widely applied methods for process safety management in enterprises. Due to its principles based on conservative qualitative judgment, it often leads too risk identification results fluorine chemical industry usually with high-risk processes keep continuity production. Most improved quantitative semi-quantitative are layer protection (LOPA) resolve over-conservative problem traditional HAZOP database LOPA. However, model, taking LOPA as main line only provider scenarios influencing factors, limited fact that can analyze complete independent layers (IPLs). Therefore, order realize or disaster causes consequences, a new method takes integrate LOPA, F&EI (fire explosion index) quantitatively calculating reduction probability failure demand (PFD) general (GPLs) PFD IPLs. With case comparison industry, proved this effectively improve complex scenarios.

A New Two-stage Iterative Method for Linear Systems and Its Application in Solving Poisson's Equation
In the current study we investigate the two-stage iterative method for solving linear systems. Our new results shows which splitting generates convergence fast in iterative methods. Finally, we solve the Poisson-Block tridiagonal matrix from Poisson's equation which arises in mechanical engineering and theoretical physics. Numerical computations are presented based on a particular linear system...
متن کاملA new method for accelerating impossible differential cryptanalysis and its application on LBlock
Impossible differential cryptanalysis, the extension of differential cryptanalysis, is one of the most efficient attacks against block ciphers. This cryptanalysis method has been applied to most of the block ciphers and has shown significant results. Using structures, key schedule considerations, early abort, and pre-computation are some common methods to reduce complexities of this attack. In ...
متن کاملDREAM: a method for semi-quantitative dermal exposure assessment.
This paper describes a new method (DREAM) for structured, semi-quantitative dermal exposure assessment for chemical or biological agents that can be used in occupational hygiene or epidemiology. It is anticipated that DREAM could serve as an initial assessment of dermal exposure, amongst others, resulting in a ranking of tasks and subsequently jobs. DREAM consists of an inventory and evaluation...
متن کاملA New Semi-Quantitative Approach to Open-Pit Mine Sustainability Assessment
Sustainability assessment has received numerous attentions in the mining industry. Mining sustainability includes the environmental, economic, and social dimensions, and a sustainable development is achieved when all these dimensions improve in a balanced manner. Therefore, to measure the sustainability score of a mine, we require an approach that evaluates all these three dimensions of mining ...
