HTRI Xchanger Suite V6.00 Hit
as of this writing, aspen technology is not providing the tasc and acol modules of the htfs suite under its university program. instead, it is offering the htfs-plus design package. this package basically consists of the tasc and acol computational engines combined with slightly modified guis from the corresponding bjac programs (hetran and aerotran), and packaged with the bjac teams mechanical design program. this package differs greatly in appearance and to some extent in available features from htfs suite.
heat exchanger networks are the most important element of a plant design. these networks can be designed in a number of ways, and this section of the book is devoted to a number of design methods. the most common way of designing heat-exchanger networks is to look for a design configuration that maximizes the heat transfer rate. this approach was used for the designs presented in this section. however, there are other options available. for example, the plant can be operated to meet the performance requirements of its process, and the design can be made to follow the specifications. this approach is described in chapter 13. another way of designing heat exchanger networks is to look for a design configuration that minimizes the energy consumption. this approach is described in chapter 14. this book also includes some material on the design of heat exchangers for one-pass systems. this chapter is devoted to the design of heat exchangers with phase change, such as cooling towers and preheaters. it is also the only chapter in the book that deals with a phase-change component that is not part of a system. in this case, the phase-change component is designed so that heat is transferred from the fluid to the material. the design of the phase-change component is presented in chapter 15.
the htri xchanger suite is available from . it is priced at $20,000, and is only available to universities, colleges and research institutions. the student can download the program and its documentation, complete a demonstration online, and then use the package for as long as they want. when their project is complete, they can continue to use the package or ask for a license.
i have made a concerted effort to introduce the complexities of the subject matter gradually throughout the book in order to avoid overwhelming the reader with a massive amount of detail at any one time. as a result, information on shell-and-tube exchangers is spread over a number of chapters, and some of the finer details are introduced in the context of example problems, including computer examples. although there is an obvious downside to this strategy, i nevertheless believe that it represents good pedagogy.
these devices transfer, or exchange heat between two flows (liquid or gas) via a conductive barrier without physically mixing them. this heat is a form of energy, and engineers have developed systems where heat exchangers are used to efficiently transfer energy between pathways. heat exchangers come in many varieties because there are many different ways to achieve this heat transfer; this article will highlight the double pipe heat exchanger, one of the most basic, but flexible configurations. we will first examine what makes a heat exchanger a double-pipe design, how they accomplish energy transfer, and what are the main advantages and applications of such a design.
the modeling is done as in the previous example using bulk stream properties and one hextran shell per hairpin. in order to accommodate the seriesparallel configuration, however, each parallel bank of hairpins is represented as a separate double-pipe heat exchanger, as shown in the diagram below. the flowsheet contains nine streams and four units (two heat exchangers, a stream divider and a mixer). each heat exchanger consists of five hairpins connected in series. aniline flows through the inner pipes and benzene flows through the annuli.
