Ultra High Purity (NH₃)

Coretech’s own technical capability will carry out the construction
of a contract, including business feasibility evaluation, plant design (including simulation), production, supply, installation and pilot test.

  • Plant specification
    - Capacity
    5,000Ton/year
    - Quality
    Input NH₃ 99.6%over, Residual : 0.4%
    (Raw NH₃ residual : H₂O, Oil, O₂, N₂, CO, CO₂, CnHm…)
    Output : 7N NH₃

  • Human Safety First
    Advantages of Automated Systems
    Mechanical advantage
    - Produce ultra-high purity NH3 gas which used in semiconductor,
      LED and heat treatment process.
    - Raw Material 99.6% -> Product 99.99999%(7N) 97% yield,
      90% operation ratio.
    - Resell VENT GAS as industrial ammonia water to maximize profit and   reduce sewage treatment costs.
    - Reduce plant construction costs based on simple production and   maximize production capacity.

    Ultra-high purity ammonia is a special gas for industrial processes such as ultra-thin liquid crystal displays (TFT-LCDs), integrated circuits and light-emitting diodes (LEDs).

He recycle system(Package)

Based on Coretech’s technology, recollects and recycles Helium which
used in semiconductor and heat treatment process to reuse.

  • Human Safety First
    Advantages of Automated Systems
    Mechanical advantage
    - After refine 99.9%(3N) He to 99.999(5N) O2 ratio under 20ppm,   recollects and reuses
    - In catalyst base, convert O2 which produce in a process recovery to H2O   with H2 chemical reaction and emit dryer
       (He)=>Catalyst+(H2+O2)=H2O
    - Through Helium recycling system, use of quench medium
       (99.5% recovery per quench cycle) and cost savings

Ultra High Purity Chlorine (Cl₂)

  • Mechanical advantage
    - Produce ultra-high purity Cl₂ gas which used in semiconductor, LED and   heat treatment process
    - Raw Material 99.5% -> Product 99.9999%(6N) 97% yield, 90% operation   ratio
    - Low operation costs due to automatic system
    - Reduce plant construction costs based on simple production and   maximize production capacity
