Scrubber Design Calculation Excel Hot High Quality -

The contaminant removal efficiency (η) can be calculated using the following formula:

When hot gas hits the liquid scrubbing media, water evaporates instantly. This cools the gas to its ( Tsatcap T sub s a t end-sub

Below is the logical order of engineering conclusions your Excel spreadsheet must display after running the calculations: Critical Dimensions Checklist scrubber design calculation excel hot

To build an efficient model, you must define several key input parameters. Gas Flow Rate ( Qgcap Q sub g ): Usually in acfma c f m (actual cubic feet per minute). Gas Temperature ( Tgcap T sub g

High evaporation rates mean substantial make-up water is required. 2. Key Design Parameters for the Excel Calculator The contaminant removal efficiency (η) can be calculated
