Chemical processes are often operated under high pressures, at high temperatures, and with fast material flows and complex manufacturing mechanisms. Thus, their operation is always more risky, environmentally more harmful, and potentially more dangerous than other types of manufacturing activities when abnormal or destructive situations arise. In the extreme, catastrophes, such as explosions, t...

Background: We consider the problem of identifying the dynamic interactions in biochemical networks from noisy experimental data. Typically, approaches for solving this problem make use of an estimation algorithm such as the well-known linear Least-Squares (LS) estimation technique. We demonstrate that when time-series measurements are corrupted by white noise and/or drift noise, more accurate ...

abstract   iran has many historic cities and villages with economic, historic and cultural values facing with many seismic faults. there have been no comprehensive studies about reducing the vulnerability of the historic villages, and the available documents describe the retrofitting experiments only about the single buildings.  lack of a comprehensive look at the subject leads to the loss of t...

This mini-review discusses some of the recent work on Novel Process Windows by the group of Micro Flow Chemistry and Process Technology at the Eindhoven University of Technology, and their associates. Novel Process Windows consist of unconventional approaches to boost chemical production, often requiring harsh reaction conditions at short to very short time-scales. These approaches are divided ...

The selection of solvents in the chemical industry is typically based on performance and economic considerations. Other relevant aspects, such as the safety implications that a given solvent generates for the process, are generally left for their consideration after the design of the process has been completed. In this work, an approach for solvent selection including safety considerations at t...

In 1998 the Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ) launched the Convention Project on Chemical Safety in developing countries. The project aims to support developing countries in the implementation of the Rotterdam and Stockholm Conventions, create human resources and institutional capacities and to demonstrate via pilot measures how chemical safety in the partner countries c...

Batch process becomes increasingly important due to greater emphasis on low-volume, higher added value products, and a need for flexibility in market driven environments. The process safety management becomes a crucial issue and its implementation has become a mandatory as the public concern on environmental impacts and safety of chemical industries heightened. This research proposes a risk ana...

There has been a recent surge in the number of disasters and incidents in occurring in the process industry (e.g. the petrochemical, chemical, food and pharmaceutical industries). The reasons include defects in process-safety management (PSM); inadequate safety management systems in companies; inadequate knowledge among managers and insufficient information about the tasks undertaken and result...

Protective controllers prevent the occurrence of forbidden states in chemical processes. In this paper we present a new and systematic approach to design a protective controller with respect to the standardized concept in process industries`Safety of Process Plants Using Process Control Systems' 1]. The plant is modelled by means of nite automata. For an ef-cient solution of the controller synt...
