MySep Studio offers Design and Performance Simulation for process phase separators.  It applies MySep’s proprietary modelling and correlations to give detailed incremental analysis of gas-liquid and liquid-liquid separation.  You can rapidly size a new separator and analyse its performance characteristics selecting from a range of internals.   Deliverables include a comprehensive report, user-customisable data sheets and to-scale equipment layout sketch.

MySep Studio users are engineers in Upstream, Midstream and Downstream Oil and Gas.  The software is widely used in Operating companies to evaluate and optimise performance of installed process equipment.   Engineering Contractors and Consultants apply MySep on greenfield and brownfield projects to produce new designs, to debottleneck existing processes and explore revamp options.  MySep is also used in separation equipment suppliers to produce reliable designs that provide their customers assurance of meeting performance.
