SOLUTION

Combining high-precision gas sensor technology to support decarbonization

RIKEN KEIKI’s patented technologies are integrated into a number of its gas sensors, and by combining these sensors together, it is possible to measure gas in a variety of situations.

Measurement performance for methanation

Methanation, the conversion of H2 and CO2 into methane, the main component of natural gas, is an extremely effective technique in helping realize decarbonization.

It is necessary to monitor the concentrations of H2, CO2, and CH4 generated during the methanation process.

Inside RIKEN KEIKI’s OHC-800 are two kinds of sensors: an optical sensor and a sonic sensor. By employing RIKEN KEIKI’s very own Opt-Sonic calculation method, which was originally conceived to measure the calorific values of fuel gas, the OHC-800 can derive both the concentrations of H2, CO2, and CH4, and the calorific value of the mixed gas, all within one unit.

Measuring the total amount of carbon in flare gas

To move ahead with decarbonization, it is necessary to know how much CO2 is generated when flaring gas.

From figuring out the amount of CO2 that is released during gas flaring to helping find ways of recycling flare gas into usable energy (fuel gas), you will find a solution to your problem in RIKEN KEIKI’s gas measurement system.

Our gas measurement system combines three high-precision sensors to measure the composition of flare gas and contributes to the reduction of CO2 emissions.

Case Study

Stable methanation

In the process of synthesizing hydrogen and CO2, we need to monitor if it is proceeding as it theoretically should. With RIKEN KEIKI’s OHC-800, we can accurately measure individual concentrations of H2, CO2, and CH4, and the calorific value of the mixed gas, all with one device. It also has a fast response time, which is useful for real-time monitoring of the production process.

Flare gas composition analysis

For decarbonization to progress, there is a need to recycle flare gas and capture the carbon from that gas. What we needed first was a simple system to monitor the amount of carbon in our flare gas. After consulting with RIKEN KEIKI, they provided us with a composition analysis performed by the dual-sensor configuration. RIKEN KEIKI's system is explosion-proof and capable of continuous measurement, but not as expensive as an analyzer. For those reasons, we believe that this was the right measurement system for our worksite.

Analyzing gas generated from an IGCC furnace

Apart from being able to measure calorific values using alternative physical quantities, the OHC-800 is easy to maintain and capable of continuous measurement, which, we think, also makes it well suited as a control device. Not only that, by adding extra sensors, it can measure concentrations of the main components of gases generated by an IGCC system, so it checked all the boxes we were looking for in terms of performance.

Hydrogen sensor for vehicles

In hydrogen vehicles, water is generated when producing energy using hydrogen, so we believe a sensor that can be used even in a high-humidity environment is necessary. The FHD has a heater function, and because it is a sensor that can be used even in environments where humidity could be high, it is useful as an automotive sensor.

High-concentration CO2 sensor

A good lineup of products to choose from. The OHC-800 has a good track record of working in CCS (carbon capture and storage) plants. CCS utilizes off-gases from oil after H2 and CO2 have been removed from them. The OHC-800 is also capable of analyzing the original composition of off-gas. We were looking for something that was simple (inexpensive, easy to measure) and could measure these things and came across the OHC-800.

Gas detector for hydrogen carriers

RIKEN KEIKI has a hydrogen gas detector that complies with IEC standards, as well as a full lineup of detectors for gases other than hydrogen. They can also provide maintenance services anywhere in the world.

HYDROGEN ENERGY

Hydrogen is receiving worldwide attention in the drive towards a carbon free society

Wide range of products for hydrogen

Hydrogen holds great potential as a key solution in the global transition to clean energy, and RIKEN KEIKI’s hydrogen sensing technology is playing an active role in various industries. We have a wide range of hydrogen-related products to cover all kinds of scenarios, whether it be production, storage, transport, supply, or usage.
