MMV-C–Stream unit conversion program


Programs like THERBAL, FlowBal, FactSage, and Metsim often produce results in inconvenient units (such as a volume unit for gas when mass is desired). MMV-C is an Excel add-in that converts these stream units from one set of units to another (SI to AES for example), and

FlowBal–Flowsheet simulator for material and heat balances

FlowBal is a spreadsheet-based heat and material balance program that uses the FREED database. FlowBal calculates heat and material balances for steady state process flow. Process devices include reactors, mixers, splitters, and heat exchangers, with both bypass and recycle flow. Material balance equations are automatiocally written around
