ABSTRACT:
A Stretford process for removing hydrogen sulfide from a high volumetric flow gas stream includes devices for introducing transverse momentum components in a multiphase flow. These momentum components enhance gas/liquid contact and improve the efficiency of hydrogen sulfide removal. Various devices for introducing the momentum components are disclosed including baffle trays, static mixer and tertiary spray devices.
