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.

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.

Reduction of CO2 emissions by reducing materials used and electricity

Off-gas Reduction at Petrochemical Plants and Refineries

In production processes unutilized gases called "off-gases" are often generated besides final products. Off-gases that cannot be utilized throughout the process are incinerated in flare stacks, which causes an increase in CO2 emissions.
Improving productivity by reducing the amount of off-gas through the use of highly accurate process gas measurement techniques contributes to save both production materials and reduce CO2 emissions.

HORIBA Solution >>
Real-time measurement of low-concentration impurity gases with high sensitivity and speed
The amount of off-gas can be reduced by measuring low-concentration impurity gases (e.g., methane, ethane, acetylene, etc.) contained in high-concentration raw gas, with high sensitivity, high speed, and in real time, and feeding back the results to the production control system.

Improving efficiency and optimization of energy use

Environmental impact assessment through Life Cycle Assessment (LCA) and other methods has become increasingly important in order to achieve carbon neutrality, which is being implemented through various measures in countries around the world. In this context, there is an urgent need to reduce CO2 emissions through the efficient use of energy.

For more information on LCA, please visit Environmental Impact Assessment (LCA and GHG Protocol) page.
