STUDY OBJECTIVES The Clean Air Act Amendments of 1990 requires that chemical facilities in the US with specified quantities of certain toxic or flammable chemicals file a five year history of accidents. This study considers the relation between the reported accidents and surrounding community characteristics. DESIGN This study is a retrospective analysis of the association between the demogra...

The Faraday Discussion on the design of new heterogeneous catalysts took place from 4-6 April 2016 in London, United Kingdom. It brought together world leading scientists actively involved in the synthesis, characterisation, modelling and testing of solid catalysts, attracting more than one hundred delegates from a broad spectrum of backgrounds and experience levels - academic and industrial re...

Many pesticides are being measured in surface water. To promote the use of monitoring data in the process of risk mapping, post-registration, and improvement of water quality, a free available Internet tool has been developed to present all measurements of pesticides in surface water on the level of individual active ingredients in a spatial framework: the Dutch pesticides atlas (www.pesticides...

This paper presents information on business intelligence (BI) and its use in industry. The specifics of BI in the chemical industry are discussed. A sample of a specific case where BI has been used through integration with an enterprise resource planning system is given. It is determined that having the key information and performance measures in place to evaluate business decisions is critical...

The production of renewable chemicals is gaining attention over the past few years. The natural resources from which they can be derived in a sustainable way are most abundant in sugars, cellulose and hemicellulose. These highly functionalized molecules need to be de-functionalized in order to be feedstocks for the chemical industry. A fundamentally different approach to chemistry thus becomes ...

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...

BACKGROUND Occupational cancer monitoring is important for cancer prevention and public health protection. A surveillance system for identifying occupational cancer risks and cancer cases in Italy that are likely to be of occupational origin using information available in the Italian Social Security archives was created and assessed. Persons employed in the private sector, the employing company...

Direct methods for the trifluoromethylation of heteroaromatic systems are in extremely high demand in nearly every sector of chemical industry. Here we report the discovery of a general procedure using a benchtop stable trifluoromethyl radical source that functions broadly on a variety of electron deficient and rich heteroaromatic systems and demonstrates high functional group tolerance. This C...

T his paper derives from an undergraduate course in chemical product design which we ®rst taught in 1998/9 and are still in the process of developing. We are in the process of writing a text book to accompany such courses. We explain our approach to chemical product design and why the subject is important. The distinctive features of product design (particularly in contrast to process design, a...

The goal of any load-management program is to maintain, as nearly as possible, a constant level of load, thereby allowing the system load factor to approach 100%. The important bene®ts of load management are reduction in maximum demand, reduction in power loss, better equipment utilisation and saving through reduced maximum demand charges. Load shifting, one of the simplest methods of load mana...
