PRESSIO 2024

PRESSIO 2024 integrates all aspects of overpressure protection analysis into one Microsoft Access relational database system eliminating the typical fragmented approach that uses multiple software tools to accomplish the same goal.  Required relief rate, relief device capacities and piping pressure drops are quantified using a variety of industry standard calculations and integrated thermodynamics.  The design of the software follows the steps outlined on the Overpressure Protection Services page as does the documentation and help videos for each form below. For all the details see below and for a quick introduction check out the PRESSIO 2024 Overview Video and Sample Documentation.
