Creating report in HYSYS
When process simulation is completed usually it is necessary to create a report which can contain information about Process Process flow streams Material streams and Energy streams Unit operations
64
We want to have specific unit sets for report
Like: Mass flowrate in lb/hr, Pressure in psia
