  • Patent number: 10518303
    Abstract: Disclosed are a thermal desorption system for oil-contaminated soil and gravel, using a microwave indirect irradiation method and including a microwave emission prevention device and a preheating device using waste heat, and a thermal desorption method for oil-contaminated soil and gravel, using the same. In addition, it is disclosed that an outer tube encompassing an inner tube extends to both sides and a plurality of ring-shaped microwave attenuation units are arranged on the inner circumferential surface of the outer tube, such that microwaves are prevented from leaking between the inner tube and the outer tube, thereby enabling eco-friendliness, and even the waste heat generated during a pollutant desorption process is utilized in the system itself, thereby enabling economic feasibility to increase further.

  • Patent number: 8221541
    Abstract: Disclosed is a heavyweight concrete composition using slag byproducts, including: ground granulated blast furnace slag; slow-cooled electric-arc-furnace oxidizing slag or atomized steel slag used as a fine aggregate; a coarse aggregate; water; and a chemical admixture based on 100 parts by weight high-early-strength cement. Thus, the heavyweight concrete composition contains a large quantity of steel slag and blast-furnace slag that are byproducts in iron-making and steel-making processes, thereby remarkably reducing an amount of emission of carbon dioxide and maximizing the recycling of waste resources for preserving the natural environment. As a result, an eco-friendly heavyweight concrete product can be made.
