Multi-Component Flash

Welcome to our multi-component flash simulator. The tool is designed to help provide a practical understanding of what hapens in a separation stage such as a flash drum, distillation tray, or reboiler.

Use the tool by entering feed conposition on a weight percent basis (wt%) and the flash temperture and pressure. Click "Calculate" to determine the vapor and liquid split and compositions.

Component vapor pressures are estimated from their boiling points and temperature using a COX diagram from J. B. Maxwell and L. S. Bonnell which allows extension to component fractions.
