Process Engineering index

The Process Engineering index, over a ten-year period (January to January), is shown in Figure 6.1a. 

Kingdom, a commercial organization, Technical Indexes Ltd., publishes the Process Engineering Index, which contains on microfilm information from over 3000 manufacturers and suppliers of process equipment.

To get the best estimate, each job should be broken down into its components and separate indices used for labour and materials. It is often more convenient to use the composite indices published for various industries in the trade journals. These produce a weighted average index combining the various components in proportions considered typical for the particular industry. Such an index for the chemical industry in the United Kingdom is published in the journal Process Engineering, Anon. (2004). The composition of this index is ...

A quarterly publication of Industrial Research Service, Inc., Dover, N.H. It gives cost data for process engineers. Each year it pubhshes an index and abstract of cost literature. 

In this thesis an inherent safety index for evaluating inherent safety in preliminary process design was presented. The inherent safety of a process is affected by both chemical and process engineering aspects. These have been dealt separately, since the index was divided into the Chemical Inherent Safety Index and the Process Inherent Safety Index. These two indices consist of several subindices which further depict specific safety aspects. The Chemical Inherent Safety Index describes the inherent safety of chemicals in the process. The affecting factors are the heat of the main reaction and the maximum heat of possible side reactions, flammability, explosiveness, toxicity, corrosiveness and the interaction of substances present in the process. The Process Inherent Safety Index expresses safety of the process itself. The subindices describe maximum inventory, maximum process temperature and pressure, safety of equipment and the safety of process structure.

It is possible to modify the index to represent a particular situation by changing the component weightings, and hence recalculate the values of the modified index for particular years. An alternative index is the Process Engineering (PE) Plant Cost Index, values are published monthly in Process Engineering journal. 

Where there are stated specifications for individual measurements y, a is sometimes turned into a kind of index comparing it to the difference in upper and lower engineering specifications. For example, one such process capability index is...

Chemical Engineering Index, CE (1957-1959 = 100) cost developed for U.S. conditions primarily as a plant construction index. Separate CE indices are published for process equipment, heat exchangers and tanks, process machinery, and for each of the cost components and for the overall weighted total for a typical process. CE instruments is used in Section d. Published in each issue of Chemical Engineering. 

The chapter on Rheological Measurements has been prepared by R.P. Williams, Reader in the Department of Chemical and Biochemical Process Engineering at the University of Wales, Swansea - an expert in the field. Thanks are due also to Dr D.G. Peacock, formerly of the School of Phamacy, University of London, for work on the compilation and processing of the Index.

Whenever a process engineer uses flow property data, he should know on what instrument and how these data were determined in order to properly assess the validity of the data. Instruments to determine flow properties are generaliy referred to as rheometers. The rheometers that wiii be briefly described in the next few sections are the capiiiary rheometer, the meit indexer, the cone and plate rheometer, the slit die rheometer, and dynamic mechanicai rheometers. For a more detailed description of these and other rheometers, the reader is referred to the literature [64-66]. A brief but good survey of commerciai rheometers was presented by Dealy [92]. 

An object-oriented language for modelling general dynamic process was successfully developed and its usage has proved efficiency in code reusability. The development of model libraries of models for thermodynamics, process engineering and other application areas is one of the future tasks. The DAE index reduction method allows EMSO to directly solve high-index DAE systems without user interaction. This fact combined with the symbolic and automatic differentiation systems and the CAPE-OPEN interfaces leads to a software with several enhancements. 

Traditionally the analytical chemist has provided support to an industrial process line by supplying information about the chemical composition of raw materials, intermediates and end-products. However, chemical composition information may not always fultil the needs of the process engineer, who is responsible for quality management and quality assurance. The quality specifications of a product frequently use parameters other than chemical composition and the relationship between chemical composition and product quality specifications is often obscure. In a marketplace in which products are accepted on the basis of performance specifications, there is an increasing interest in on-line analytical techniques that can predict polymer product performance beyond melt index, YI, melting and crystallisation temperature.
