Accurate separation modelling in leading process simulators

Page last modified
June 17 2024

MySep Engine™ gives users of leading process simulators access to MySep separator modelling rigour for vapour-liquid separation, within their dynamic or steady state simulations. This brings much more accurate overall process modelling in applications where carry-over will have significant impact on heat and material balances. 

Carry over of liquids with vapour can have a significant impact accuracy of material and heat balances in process simulations.  The MySep Engine module embeds an accurate representation of gas-liquid separation behaviour inside a dynamic or steady-state process model.  In addition to physically based representation of pressure drop and carry-over performance MySep’s practical warnings indicate where operational limits are exceeded.  

Case studies on production optimalisation, troubleshooting and digitalisation can be found on
