Sulzer supports large-scale carbon capture project in Japan

23rd April 2024

Sulzer’s mass transfer equipment will be at the core of one of Japan’s large-scale carbon capture plants. Based in Yamaguchi Prefecture, the facility will support the decarbonization of a leading chemical manufacturer by leveraging Sulzer’s extensive expertise and specialized mass transfer technologies.

Column internals and packing for the entire commercial-scale carbon capture process will be supplied by Sulzer, global leader in separation and mixing technology. Including the direct contact cooler, absorber, and regenerator columns with the largest internal diameter measuring 2.8 m (approx. 9.2 ft).

The units will feature MellapakCC™ structured packing, AYPlus™DC structured packing, and tailored column internals designed to maximize performance when capturing carbon dioxide (CO2) from flue gases. These solutions minimize pressure drop and solvent emissions, reducing the plant’s capital and operational expenses as well as its environmental footprint.

Prior to the selection of the mass transfer equipment, Sulzer conducted extensive in-house feasibility, pilot-scale testing, and pre-engineering services to develop a highly effective setup. In addition, the company will support the installation of the column internals and structured packing through its expert and localized Tower Field Service offering.

Sulzer Chemtech Division President Uwe Boltersdorf comments: “Our carbon capture solutions are being leveraged worldwide to help create a carbon neutral future. We are extremely proud to support such a key decarbonization project in Japan. Through our advanced testing capabilities, we were able to develop the most suitable design for this specific application, ultimately maximizing the carbon emission reduction potential of the plant. 

When it came to specifying the equipment, the customer was truly captivated by the capabilities of our separation technologies, in particular the MellapakCC structured packing, which is unique in the marketplace. We also received extremely positive feedback about the collaboration and look forward to completing this project and supporting similar ventures in the future.”
