CAFE IN-PROCESS DESIGN - POTENTIAL AND LIMITATIONS

CAFE tools comprise computer based tools and methods for the design of chemical processes the use of which is indispensable in modern chemic al engineering. This paper discusses the degree to which CAFE is alrea dy applied and whether limitations exists. Within BASF, the CAFE frame work is provided by the ''ProcessNet'', which integrates numerous simu lation and design tools. The engineer relies alternatively on in house or commercial software. The advantage of CAFE in terms of efficiency depends not only on complex programs, but also to a large extent on th e multiple use of intermediate data and program modules. The ProcessNe t also features a hierarchical file structure to support the engineer' s desktop management. The CAFE environment is being continuously impro ved. The main constraints on CAFE today are are for example the missin g link between fluid and solid applications, a deficit in data managem ent and the poor state of development of advanced or special programs, the progress of research in this area is followed with great interest .
