Methyl tertiary butyl ether (MTBE) is known as a promising substitute for tetra ethyl lead (TEL) in order to increase the octane number of gasoline. MTBE process, as many other processes, has two distinguished section, namely reaction section and separation section. In this paper we focus only on synthesis and optimization of separation section of this process. In order to achieve this obje...

  In this paper, authors tackle three very important questions that need to be answered if a theory of design is to be constructed. The first is what designers do, Which we attempt to illustrate with the help of case studies and theories of design practice. The second question is what guides designers. Here, authors try to present some of the proposed normative positions about design, to show t...

This paper describes the application of process integration principles to the design of oil refineries hydrogen network. In this regard, a design hierarchy as well as heuristics and required guidelines are proposed. The recommended rules compensate lack of procedure to the design and make the design process easier. The guiding principles of the design are based upon pinch technology and ext...

In the developing world, skills in innovation and creative design have emerged as key attributes for graduating designers. Creativity is essential if we want to generate new solutions to the considerable and complex problems in architecture. Metaphor is frequently expressed as a key tool for enhancing creative design, yet little empirical research has been performed on how novice designers can ...

The Taguchi method is a useful technique to improve the performance of products or processes at a lower cost and in less time. This procedure can be categorized in the static and dynamic quality characteristics. The optimization of multiple responses has received increasing attention over the last few years in many manufacturing organizations.  Several approaches dealing with multiple static q...

design process is one of the main processes practiced in engineering. in this paper, after demonstrating the place of engineering among the topics discussed about technology, design process is studied from the perspective of three different models. the first model, vincenti’s model, provides an abstract explanation of the design process; the second model, bucciarelli’s model, has a sociological...
