Metal Recovery Technology

Recovery of Precious Metals from Industrial Wastes

The key point of the technology

Most of the companies, generating fermentation wastes, throw their wastes into the sea.
We invented high value sorbents out of the wastes to recover precious metals or remove heavy metals.
The new invention, Bio-sorbent overwhelms IER(Ion Exchange Resin) in every way, and it is also eco-friendly and highly efficient.
The entire recovery & removal cycle of Bio-sorbent is environmentally friendly, and it enables us to overcome the shortcomings with the wet process.
he recycling of the wastes and the concrete securement of metal resource are the beauty of the technology

The necessities of technical revolution

In various industry areas, using heavy metals and precious metals, called non-ferrous metals, already became generalized.
The wastes containing these metals have been increasing continuously.
That is why there are growing needs to deal with these wastes more economically and eco-friendly. Globally, it is strongly prohibited to throw fermentation wastes into the sea; The regulation takes effect in 2016 in Korea. This technology will be killing two birds with one stone under the circumstances.

Gas Reforming Technology

From fuel cells to hydrogen energy

What is the fuel cell?

It is an energy transforming technology from a chemical reaction between hydrogen and oxygen to electric power without emitting pollutants.
Environmentally friendly and high-efficiency technology.
From hydrogen on the anode and oxygen on the cathode, it generates energy as a reverse reaction of electrolysis. The type of the energies are electricity and heat.
The main source comes from town gas (LNG, LPG), Biogas and so on, and transform them to hydrogen. Since then, the technology is not limited by geographical factors.
It can be used not only for electricity, but for also hot-water supply and heating.

The reasons to become the next generation energy

  • High-efficiency

    • The technology directly transforms fuel cells into energy.
    It shows 10~20% higher efficiency, compared to the existing method.

    • The fuel energy technology reaches 80% of energy efficiency as 40% of electricity and 40% of heat energy.
    It is able to use both energy types simultaneously

  • Green generating process

    • Hydrogen and oxygen as the raw materials are harmless,
    and the transformed material, water is also innocuous.

    • Carbon dioxide, emitted during the transforming process,
    is less than a thermal power generation.

The reasons to become the next generation energy

  • Reformer

    The device catalytically reacts fossil fuels, and transforms them into reformed gas. The gas is injected into fuel cells.

  • Stack

    The device generates energy by an electrochemical method between hydrogen from Reformer and Oxygen

  • Electricity inverter

    The device changes direct current, coming from fuel cells, to inter current.

Reformer for hydrogen supply

  • Partial Oxidation (POX)

    The device catalytically reacts fossil fuels, and transforms them into reformed gas. The gas is injected into fuel cells.

  • Steam Reforming (SR)

    The power generation method by natural gas and steam is the most economical means, since the hydrogen production efficiency is higher than 70%.

  • Autothermal Reforming (ATR)

    Partial Oxidation (POX) and Steam Reforming (SR) occur at the same time. Therefore, this system can be operated without heat supply from outside.

Reforming System Diagram

  • Desulfurizer

    Sulfur in town gas should be eliminated, since reforming catalysts can be contaminated by sulfur, and it can cause deactivation.

  • Primary Process

    Separation of fuels in the hydro carbon line for reforming process. The fuels are separated into Hydrogen and Carbon.

  • Selective Oxidizer

    Decreasing carbon monoxide to several ppm by means of using air to supply reformed gas into stacks.

  • Steam Generator

    Heating water to supply steam for the reforming process.
