The MultiFlash properties package contains an extensive library of thermophysical and transport properties that can be used in multiphase calculations in a flexible manner. Powerful models for flash calculations can be employed for any combination of liquid, gas, and solid phases. Besides a large number of models for processing chemicals (such as equations of state or group contribution methods) the package contains a variety of models that make it well suited for applications in oil and gas industries (e.g. for modeling flows in pipelines) or polymer processing (e.g. using the recent PC-SAFT equation of state).
Such a standalone properties package obviously benefits from the integration with a large number of software packages that require thermophysical and transport properties. This is where CAPE-OPEN comes into play: the use of the standard interfaces allows customers to make use of the MultiFlash package in a plug and play manner across the chemical design and operation lifecycle. Models and data provided by MultiFlash can now be used in different commercial or in-house software packages without having to recode the interface between the package and e.g. the process simulator in which it is to be used. This development also simplifies life on Infochem’s side because the use of a single interface to reach a broad base of customers reduces the efforts to be spent in code development and support. The MultiFlash package is now in use in combination with the CAPE-OPEN interfaces at large chemical engineering companies such as BP or BASF.
