Reduction of CO₂ Emission

By improving productivity and managing energy use well, we can contribute to the reduction of CO₂ emissions themselves. In particular, the amount of CO₂ released into the atmosphere can be significantly reduced by separating and capturing CO₂ generated during combustion processes such as manufacturing and power generation. HORIBA's wide range of "measurement" solutions such as gas measurement, material analysis, energy management and services can also contribute to CO₂ reduction through CO₂ separation and capture during product manufacturing and reduction of material and electric power consumption.

Reduction of CO₂ Emissions through Separation and Capture

CO₂ Separation and Capture in Combustion Processes

CO₂ is separated and captured from the exhaust gas generated in the combustion process. This is the CC (Carbon dioxide Capture) part of CCUS (Carbon dioxide Capture, Utilization and Storage). From the standpoint of cost and technique, the "chemical absorption method" is considered advantageous for thermal power plants, the "physical adsorption method" for chemical plants, and the "membrane separation method" for cement and steel plants.

The separated and captured CO₂ is also utilized in the carbon recycling process. For more information on carbon recycling solutions, please visit here.

1. Chemical Absorption Method (Amine Method)
To produce high-quality CO₂, it is important to measure and monitor CO₂ and impurity gases in the separation, capture, and purification processes, as well as in pre and post treatment.

Pretreatment: Generally, sulfuric gases contained in flue gas are removed by desulfurization. SO₂ gas needs to be measured and monitored during desulfurization, and CO₂ gas needs to be measured and monitored after desulfurization.
Separation, Capture, and Purification: In the amine process, monitoring whether CO₂ reacts with amines in the absorption column and is captured is necessary for optimal plant control. This is accomplished by measuring and monitoring the CO₂ gas. Measurement and monitoring of the pH and conductivity of the amine solution is also required for stable process operation.
Post-treatment: The amount of CO₂ adsorbed can be confirmed by measuring the solution after adsorption with a TOC meter. It is also possible to determine CO₂ separation by measuring the solution itself after the CO₂ separation process. In addition, the unwanted gas after CO₂ removal needs to be treated, and the exhaust gas must be measured and monitored to confirm that it achieves a level at which it can be finally emitted from the chimney.

2. Physisorption Method

By observing adsorption and other state changes that occur on the zeolite surface using a Raman microscope that captures the bonding state of substances, you can evaluate the performance and degradation of the adsorbents.

3. Membrane Separation Method

The reaction efficiency and replacement cycle of the membrane can be predicted by measuring the amount of carbon attached to the separation membrane and the amount of sulfur in the catalyst after the reaction to evaluate their degree of degradation.

CO₂ Separation and Capture in the Blue Hydrogen Production Process

By separating and capturing the CO₂ generated in the production of coal- and natural gas-based "gray" hydrogen, the "blue" hydrogen is produced with no CO₂ emissions into the atmosphere during production. We also contribute to blue hydrogen production with solutions cultivated in CO₂ separation and capture in the combustion process.
