  • Recovery of promoters used in flue gas desulfurization
    Patent number: 4724130
    Abstract: In flue gas desulfurization, sorbent promoters are recovered by mixing collected particulates with water to form a slurry. The slurry is dewatered and wet solids are disposed. The recovered material contains water soluble desulfurization promoters and is reinjected in a flue gas desulfurization humidification system. The recycle allows recovery of water soluble promoters and reduces consumption. In addition, for promoters having undesirable disposal characteristics, the system improves the disposal characteristics of the waste solids.

  • Reduction of liquid atomizer droplet size
    Patent number: 4720290
    Abstract: The dispersing ability of atomizing nozzles is improved by dissolving a portion of the dispersion gas into the subject liquid at pressures of at least 50 psi. Explosive expansion of the dissolved gas in the nozzle greatly aids atomization. Further atomization effects are obtained by adding a surfactant to the subject liquid.
