Essential Components of Your Post

Remove 200 kg/h of air (suction) from a vacuum column at 0.3 bar abs, compressing to 1.2 bar abs, using 8 bar g steam.

👉 – includes sample data and validation against published case studies.

Look-up tables for steam, air, or specific hydrocarbons to automate enthalpy and entropy calculations. ejector design calculation xls

Here is how you should organize your rows and columns in Excel.

Steam ejectors (or eductors) are crucial components in process industries, offering a reliable, low-maintenance solution for creating vacuums, mixing fluids, or handling gases without moving parts. Designing an efficient ejector, however, requires complex thermodynamic calculations. Utilizing an spreadsheet is the most efficient way to manage these calculations, optimize geometry, and ensure system performance.

Suction Fluid (Air):

Modeling the momentum transfer between the motive and suction streams. This is the most complex part of the design, often assuming constant pressure or constant area mixing.
