Overview of Process Economics

Appendix III provides an overview of process economics. Two principal categories of expenditure are particularly important fixed and operating costs. The fixed cost ( ) can be distributed over the service life of the equipment as an annualized fixed cost ( /yr). The total annualized cost (TAC) of the system is given by...

Having defined and gathered data adequate for an initial reserves estimation, the next step is to look at the various options to develop the field. The objective of the feasibility study is to document various technical options, of which at least one should be economically viable. The study will contain the subsurface development options, the process design, equipment sizes, the proposed locations (e.g. offshore platforms), and the crude evacuation and export system. The cases considered will be accompanied by a cost estimate and planning schedule. Such a document gives a complete overview of all the requirements, opportunities, risks and constraints. 

Process economics is an essential element of a good design procedure. The objective of this appendix is to provide an overview of basic concepts in cost estimation and economics of chemical processes. For more details, the reacker is referred to Humphreys and Wellman (1996), Peters and Timmerhaus (1991), Garrett (1989) and Ulrich (1984). 

This chapter attempts to give a comparative overview of the process and to illustrate the economic and ecological advantages. 

The current state of analytical SPE was critically reviewed and no major changes of the technique have been observed. Overviews of the developments of the extraction technologies of secondary metabolites from plant materials refer to three types of conventional extraction techniques that involve the use of solvents, steam, or supercritical fluids. Each technique is described in detail with respect to typical processing parameters and recent developments. Eollowing the discussion of some technical and economic aspects of conventional and novel separation processes, a few general conclusions about the applicabilities of the different types of extraction techniques are drawn. ... 

Biomass-based processes for the production of hydrogen can be either thermochemical or biological and can produce this clean carrier directly or through an intermediate, storable product. Also, the use of coproducts has to be addressed to improve the process economics and in view of the sustainability of using this natural resource. A recent overview of the status of the different technologies is given in an IEA/NREL review5 and further by Czernik et al.8... 

I have presented a general socio-political overview of China. The in-depth analysis of China s political environment is both necessary and relevant. The prevailing political climate in China determines not only China s economic development path, but also its scientific and technological development path. Politics is China s "Great Helmsman". In the process, I hope I have provided sufficient background information on the Chinese psyche and society to aid in interpreting nuances when interacting with the Chinese. 

The CNG acid gas removal process is distinguished from existing AGR processes by three features. The first feature is the use of pure liquid carbon dioxide as absorbent for sulfurous compounds the second feature is the use of triple-point crystallization to separate pure carbon dioxide from sulfurous compounds the third feature is the use of a liquid-solid slurry to absorb carbon dioxide below the triple point temperature of carbon dioxide. Pure liquid carbon dioxide is a uniquely effective absorbent for sulfurous compounds and trace contaminants triple-point crystallization economically produces pure carbon dioxide and concentrated hydrogen sulfide for bulk carbon dioxide absorption the slurry absorbent diminishes absorbent flow and limits the carbon dioxide absorber temperature rise to an acceptable low value. The sequence of gas treatment is shown in Figure 1, an overview of the CNG acid gas removal process. 

Constructive prospects to solution of this problem are connected with the development and application of complex models to evaluate possible changes in climate and socio-economic development. Parson and Fisher-Vanden (1997,1999) and Dess-ler and Parson (2005) prepared a detailed overview of the methods and results of numerical modeling of global climate changes with the dynamics of socio-economic processes taken into account, in which basic aspects of so-called integrated assessments (IAs) were discussed. The main goal of such developments is substantiation of recommendations for decision-makers in the sphere of ecological policy. 

As an essential transportation and heating fuel, and principal raw material for many process industries the future supply of natural gas is an always critical issue. Because it is more widely geographically distributed than petroleum, maintaining an adequate supply at stable pricing is a national and world economic and societal concern. In concluding this section the authors feel an overview of... 

It has been stated that chemistry is the study of matter and its transformations. One of the major objectives of this book is to provide information on how the basic raw materials from the earth are transformed to produce inorganic compounds that are used on an enormous scale. It focuses attention on the transformations of a relatively few inorganic compounds available in nature into many others whether or not they are at present economically important. As you study this book, try to see the connection between obtaining a mineral by mining and the reactions that are used to convert it into end use products. Obviously, this book cannot provide the details for all such processes, but it does attempt to give an overview of inorganic chemistry and its methods and to show its relevance to the production of useful materials. Petroleum and coal are the major raw materials for organic compounds, but the transformation of these materials is not the subject of this book. 

More examples for applied organocatalysis are presented by H. Groger, who gives an overview of organocatalytic methods already applied on a technical scale. Based on case studies, he shows several examples that satisfy the criteria of a technically feasible process such as high catalyst activity and stability, economic access, sustainability, atom economy, and high volumetric productivity. 

Sampling procedures provide an overview of the type of sampling that is conducted. They need to state, for instance, whether the samples are taken for process control, for product release, or for environmental reasons. The procedures alert us to what particulars to look for in the field when we do the walk-through. We can ask those who sample how they were trained to sample and if they are familiar with the procedures. We can compare what the procedures state to what we observe and then note any discrepancies. It is not uncommon to find differences between what is written and what is practiced. These differences may have important economic, safety, or environmental consequences. 

Chapter 9 presents an overview of modem fermentation processes and their application in food, pharmaceutical, and industrial chemical industries. The social and economic importance of fermentation processes is discussed.
