✦ Synopsis

An analytrcal model was developed to determme the amount of non-condensable gases -essentrally oxygen 02, nitrogen N2 and carbon dioxid CO2 -released during adiabatrc evaporatron m the chambers of MSF-desalination drstrllers. For a once-through type plant without deaerator and for a recycle type plant wrth vacuum deaerator the degasrfication schemes are illustrated and the resulting gas-concentratrons in the vapor are compared for different venting rates and cascade configurations.
