Reduction of CO2 Emission

We can contribute to the reduction of CO2 emissions by improving productivity and management of energy usage. The amount of CO2 released into the ambient atmosphere can be significantly reduced by extracting COgenerated from the combustion process. Our wide range of measurement and analysis technologies for gas, material, and energy management can contribute to reductions of CO2 emissions.

GHG (Greenhouse Gas) Protocol Calculation of GHG emissions based on Scope 1, 2, and 3

Based on "Basic Guidelines for Calculating Greenhouse Gas Emissions through Supply Chains (Ver. 2.4)" by the Ministry of the Environment and the Ministry of Economy, Trade and Industry.

Based on the GHG Protocol, businesses that emit more than a certain amount of GHGs are required to calculate, report, and disclose their GHG emissions throughout their supply chain.

What is supply chain emissions

GHG emissions represent not only the emissions of the business itself, but also the total of all emissions generated throughout the entire supply chain related to business activities, from the procurement of raw materials to manufacturing, logistics, sales, and disposal. The GHG Protocol classifies the scope of GHG emissions (scope) into three categories. 

Reduction of GHGs

N2O, which has a global warming potential 298 times that of CO2, and CH4, which has 25 times that of CO2, are required to be reduced and controlled in various industries, along with CO2, and technology development is underway to further reduce these three GHGs.

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. 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 Restraining the Emission Factors Themselves

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.

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.

Utilization of Cellulose Nanofiber (CNF)

Nanocellulose such as Cellulose Nano-Fiber (CNF) is a plant-derived carbon neutral material that is expected to be utilized in various base products as a lightweight material with high strength and elastic modulus.
It is also expected to be applied to material recycling and heat utilization in thermal recycling after use. We offer high performance particle characterization analyzers that enable material characterization at the nano-level.
