    Inventor: Cheol Lee
  • Patent number: 12275908
    Abstract: Proposed is a method of emulsifying fuel oil and a desulfurization agent. The method includes (a) a step of adding a desulfurization agent to fuel oil for line mixing thereof, (b) a step of generating droplets in the resulting mixture of step (a), (c) a step of causing the resulting mixture of step (b) to pass through a magnetic field so that the mixture can be magnetized, (d) a step of subjecting the resulting mixture of step (c) to vortex mixing, and (e) a step of causing collision of the resulting mixture of step (d). The method uses fuel oil as a continuous phase and a water-based desulfurization agent as a disperse phase and emulsifies the desulfurization agent in the fuel oil through water-in-oil (W/o) emulsification so that the desulfurization agent can be stably dispersed in the fuel oil. Since the fuel oil and the desulfurization agent are burned together during combustion, sulfur oxides that may occur during the combustion are removed, whereby sulfur oxide emissions are reduced.

  • Patent number: 12270138
    Abstract: Reinforcing filaments or fibers, such as aromatic polyamide (aramid) fibers, can be reliably measured and consistently mixed into asphalt cement concrete by soaking the fibers in a wetting agent, then severing them to a desired length, and mixing the segments with other ACC ingredients. The wetting agent holds the fibers together loosely, so they can be distributed more uniformly throughout the ACC without clumping. The wetting agent soaks into the ACC mixture and/or evaporates, leaving the reinforcing fibers behind.
