WHAT IS ASPEN? A computer program for steady-state process simulation (a.k. process Flowsheeting) Developed for the simulation of Chemical Petrochemical Processes Coal-based Processes Petroleum Refining Polymer Processes One of many commercially available flowsheeting programs such as PROII (Simulation Sciences) HYSIM (Hyprotech) ChemCad(Chemstation)

HEAT EXCHANGER NETWORK SYNTHESIS 1: TARGETING OBJECTIVES: 1 Determine the minimum energy inputs required for a process 2Determine the minimum number of heat exchangers required to transfer this energy 3Develop a methodology for determining where these heat exchangers should be placed in the process

层次分析法(Analytic Hierarchy Process,简称AHP)是对一些较为复杂、较为模 糊的问题作出决策的简易方法,它特别适用于那些难于完全定量分析的问题。它是美 国运筹学家T.L. Saaty教授于70年代初期提出的一种简便、灵活而又实用的多准则 决策方法

The Fourth method: Definition a dictionary will give you two different definitions of the word definition: ( \a statement of what a thing is\and(2)a\a statement or explanation of what a word or phrase means or has meant. \ In the strict sense a definition as we shall use the word here is not of a thing. but of a word or of a process The process of making a definition is not, however, a mere game of words. It is clear that we cannot make a usefu

Thermophysical properties of meat In chilling, freezing, thawing and tempering processes heat has either to be introduced or to be extracted from the meat to change its temperature The rate at which heat can be removed or introduced into the surface of meat is essentially a function of the process being used, for example air blast, plate, immersion, and so on. However, the rate at which heat can flow from within the meat to its surface is a function of the thermophysical prop- erties of the meat. If we continue to
