Abstract or Description

Abstract: "CEPHDA is a computer-aided chemical engineering process design tool, which we implemented in the 'ASCEND' (Advanced System for Computations in ENgineering Design) modeling environment. CEPHDA contains models for levels 2 (treating a whole process as a 'black box') and 3 (implementing recycle flows) of the hierarchical design process which Douglas (1988) developed in his text 'Conceptual Design of Chemical Processes.' We have tested CEPHDA by modeling a three step process from toluene to benzene to ethyl benzene to styrene. The CEPHDA library was created so that inexperienced process engineers can readily create, evaluate, and optimize such models."
