  • Hydrogen sulfide removal process
    Patent number: 4603035
    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.

  • Hydrogen sulfide removal process
    Patent number: 4511544
    Abstract: A Stretford process for removing hydrogen sulfide collects a horizontal pool of liquid downstream of the primary gas/liquid contactor and accelerates a multiphase flow along the surface of that pool and along a serpentine path. Additional gas-liquid contact is effected by the interaction of multiphase flow and structural components establishing the pool and causing the acceleration.
