Our simulation software convergence engines have been proven in extensive use within industry to provide you with accurate results.  In fluid flow simulation, we set the standard when we developed the first integrated liquid, gas, and 2-phase pipeline network analysis software with a patented graphical user interface which has been the most widely used in the chemical and refining industry since 1993.  A Gaussian elimination matrix is formed to solve all of the equations for pipeline pressure drop and equipment pressure drops based on the Darcy equation for liquids and gases.  For compressible gases, we use the Peng-Robinson equation of state to accurately predict the non-ideal gas density and all of our pure component data comes from the latest version of the AIChE DIPPR database.

Our process simulation engine was developed over a 30 year period and has been used to build major refineries and petrochemical facilities.  Our flare header simulation software computational engine has been used in industry for over 30 years and our pressure relief valve simulation engine has been used in industry for 20 years on hundreds of facilities and applications.  Our simulation software programs for fluid flow, process, flare, and PRV analysis incorporate the most widely accepted thermodynamic methods and property calculations recommended by industry experts to provide you with superior results.  With EPCON simulation software, you can choose your desired thermodynamic packages from the American Petroleum Institute (API), the Dortmund Data Bank Software and Separation Technologies (DDBST), and the Gas Processor’s Association (GPA) to provide you with the best possible thermophysical properties and simulation results.
