Other special gas
separation device

We design and manufacture custom-made device to meet the diversifying needs of our customers.

I want to reuse only the necessary components from the exhaust gas generated from factories and facilities

I want to purify the raw material gas and generated gas in various manufacturing processes

In this way, we examine, design, and manufacture device according to customer requests.

Contributing to the reduction of greenhouse gas
emissions and a decarbonized society.

Carbon dioxide concentrator

Carbon dioxide is concentrated to a high purity (e.g. 90 vol% or more) and recovered from boiler flue gas.
Carbon dioxide is said to be one of the causes of global warming.

By recycling the collected carbon dioxide, we can contribute to the realization of a carbon-neutral society.

Inlet gas composition example	CO₂ 30〜60 vol% N₂ 30〜55 vol% O₂ 10〜15 vol%
Product CO₂ concentration	≧ 90 vol%

※Regarding the CO₂ concentration of the inlet gas composition, we also support low concentrations, so please contact us.

More use of Hydrogen gas
and Realize Hydrogen Society

Hydrogen purification device

Refine to high purity Hydrogen (ex. 99.9 vol% or more) from Steam-reformed mixed gas (H2, etc).

Hydrogen purification device catalog

Inlet gas composition example	Steam reformed gas H₂ 77 vol%　CO₂ 20 vol%, CH₄ 2 vol%　CO 1 vol%
Product hydrogen flow rate	0.16～270 Nm³/h
Product hydrogen concentration	≧ 99.9 vol%

Future Hydrogen Society

On December 26, 2017, Japan announced its "Basic Hydrogen Strategy". This is because hydrogen has two characteristics when viewed as an energy resource.

Can be made from various resources
Does not emit carbon dioxide even when used

Due to these characteristics, hydrogen is attracting attention as a new sustainable energy.

Contributing to effective use of biogas

Methane purification device (biogas purification device)

We purify methane from biogas generated from digestion tanks of sewage treatment plants, bio-fermentation tanks of food processing companies and livestock farmers.

Our biomass-related business

Inlet gas composition example	CH₄ 60 vol%　CO₂ 40 vol%
Product methane concentration	≧ 90 vol%
Inlet gas flow	5～500 Nm³/h
Product gas flow rate	2.5～260 Nm³/h

Methane purifier (biogas purifier) — device with inlet 50 Nm³/h

Sustainable energy

The utilization of carbon-neutral biomass resources is attracting attention due to social needs such as the construction of a recycling-oriented society and the promotion of measures against global warming. Biogas obtained from biomass resources such as sewage sludge, garbage, and livestock manure has the advantage of stable supply and high sustainability.
Refined methane obtained from biogas is expected to be used as an alternative fuel for natural gas, such as gas power generation, boiler fuel, and raw material for steam reforming (hydrogen production).

Proposals for customers
who are having trouble with gas separation

Other special gas separators

Separation and purification of small-scale gas that is difficult to implement due to high cost
Separation and purification of customer-specific exhaust gas, etc.

For such projects, we will consistently support our customers, from laboratory-level testing to actual machine design, production, and on-site adjustments.
