A Review on Process Controllability

Kurt Pedersen†, Sten Bay Jorgensen†and Sigurd Skogestad‡†Department of Chemical EngineeringTechnical University of DenmarkLyngby, Denmark‡Department of Chemical EngineeringNTNUTrondheim, NorwayNovember 26, 1998Abstract: Definitions of terms used within process fle xibility design and controllability assessment are given andtheir relations discussed. Methods for controllability evaluation and methodologies for integrating these into thedesign process are reviewed for some modes of operation. Basically two types of evaluation and design methodsprevail; One type is based upon linear model analysis, whereas another type is based upon physical chemical in-sight and thus provides nonlinear information.In process design practice the plant piping and instrumentation diagram evolves iteratively using mainly experi-ence and process reasoning to address questions related to plant controllability. It would be desirable to be able toaddress such questions more quantitatively at different abstraction levels during process design such that control-lability evaluation can be integrated into the design process.This paper is an unpublished internal report, which is produced within the EU CAPE.NET project (workinggroup 3).
