Environment System Research Division

The Environment System Research Division is working on state-of-the-art technologies of environmental machineries and systems with high efficiency and low pollution in order to actively cope with social issues such as fine particle air pollution and global warming. Our division has the core environmental technologies in plasma, air/water treatment, engines, combustors, and so on, and we are developing highly-efficient and environmentally-friendly power generation systems for the future based on these technologies.

Department of Environmental Machinery

Research Topics

  • Gas cleaning systems using electrostatic technologies for industries and indoor air quality
  • Particulate precursor reduction technology
  • Gas clearing system in coal and renewable energy power plants
  • Advanced technology for purification and waste water treatment
  • Membrane-based desalination

Major Achievements

Commercialization of an Electrostatic Gas Cleaning System for IT Manufacturing Industries

This air pollution control technology is aimed at solving environmental issues such as emission regulations and civil complaints related to harmful gases and ultrafine particles from IT manufacturing industries. This technology perfectly removes soluble gases, ultrafine particles, and mists simultaneously in the IT manufacturing process by using advanced electrostatic methods.

Department of Clean Fuel & Power Generation

Research Topics

  • Biocrude-oil Production by Fast Pyrolysis of Biomass
  • Clean Gas Turbine Combustor for Power Plants
  • Fuel Cell Hybrid System and BOP Technology
  • Low-Carbon Agricultural Energy System

Major Achievements

Low-NOx Combustor for Large Gas Turbine Power Plants

We have successfully developed our own low-NOx combustors for large gas turbine power plants. NOx emission, which also can be a source of fine dust, was reduced by improving fuel mixing and combustion instabilities were suppressed by the fine tuning of the swirl flow fields. Our combustors were installed and operated on an active power plant, the first such case in Korea. More than 30% NOx reduction has been reported after 3 years of operation.

Department of Engine Research

Research Topics

  • Novel-concept and new-fuel power systems
  • Combustion control technology for high efficiency engines
  • After-treatment of engine exhaust gas and particulate
  • Fuel supply systems for low-carbon fuels
  • Thermal energy management of heat-powered machines

Major Achievements

Hydrogen-enriched Compressed Natural Gas (HCNG) Engine

Development of both ultra-lean burn and stoichiometric HCNG engine satisfying the EURO-6 emission standard and reducing more than 15% of CO2 emission without expensive de-NOx devices.

Department of Plasma Engineering

Research Topics

  • Energy and environment technologies using plasmas
  • Large-area and high-speed plasma surface treatment technologies
  • Plasma process and equipment for next-generation renewable energy devices

Major Achievements

Low-pressure Plasma Technology for Eco-friendly Semiconductor Processing

This is an innovative technology that reduces pollutants emission from the semiconductor processing by applying a plasma reactor before a vacuum pump. This technology enables ecofriendly processing, preventing safety-related accidents and extending the lifespan of vacuum pumps in the processing lines. The technology has been commercialized by a medium-sized vacuum company, LOT Vacuum Co. Ltd., and over 300 units are currently running in the semiconductor manufacturing lines at Samsung Electronics.
