Chemical process simulators play a vital role as a tool to evaluate different design options in refinery or chemical process industries. The CAPE-OPEN interface standard aids process modeling components to seamlessly integrate thermodynamic packages and unit operation modules provided by different vendors in any CAPE compliant process modeling environment. This paper presents the experience in migrating the UniSim CAPE-OPEN Thermodynamic socket from CAPE-OPEN Thermo interface version 1.0 to 1.1. This paper also discusses the potential advantages of CAPE-OPEN thermodynamic interface version 1.1 over 1.0 with a case study of using Infochem's Multiflash CAPE-OPEN Thermodynamic 1.1 compliant server in UniSim Design Flow sheeting environment addressing specific chemical process industry problem.
