ABSTRACT:
A process for operating a jet scrubber includes inducing gas to flow through a venturi by spraying coarse liquid droplets into the venturi inlet. The liquid is sprayed at the minimum rate needed to pump the gas. Additional liquid is atomized into fine droplets and introduced into the venturi throat. The ratio of combined liquid flow rates to the gas flow rate is substantially greater than the ratio of the minimum liquid flow rate to the gas flow rate. Hydrogen sulfide gas can be cleaned from a gas stream using a Stretford liquid according to the process.
