Wirtschaftlichkeit als Kriterium für die Entwicklung, Auslegung und Auswahl von Apparaten und Maschinen für Prozeßstufen

Abstract

AbstractEconomy as a criterion for development, design, and choice of equipment and machines for process steps. The object of this paper is to show how a supplier of individual machines can influence the total costs of a chemical processing plant. This influence is quantified using actual examples based on the development of a product range, the optimizing and matching together of mechanical and thermal separation processes, and the selection of the most suitable types of equipment. Studies show that the products and services of an equipment manufacturer can influence substantially more than just capital investment costs and interest charges with their consequent effects on the annual running costs of a plant. It is possible to reach more economical solutions for important stages in a manufacturing process if the plant designers and the equipment manufacturers work closely together. A too tightly specified enquiry can prevent a manufacturer from offering the technically and economically optimized solution. By involving equipment manufacturers and correctly using their know‐how one can tap a substantial potential for the reduction of plant running costs.
