. As the hot gas hit the recirculating liquor, it would evaporate water instantly, cooling the gas but shrinking its volume and changing the density. The Inputs:
Excel drop-down drives different calculation pathways:
offers a downloadable spreadsheet for preliminary single-stage spray tower calculations, including removal efficiency and pressure losses. Color-code these cells (e
Create an X-Y Scatter chart plotting the vs. the Equilibrium Line . This visual check ensures the operating line does not cross the equilibrium line (which would cause pinching and make the design impossible).
