LOTTE Chemical and LOTTE Construction Begins Development of

Highly Pure Nitrogen Production Technology Using Carbon Capturing Gas Separator

■ LOTTE Chemical and LOTTE Construction signs MOU for developing highly pure nitrogen production technologies

    using carbon capturing gas separators... Pursuing process development, testing facility installation and operation,

    review commercialization application

■ Produced highly pure nitrogen can be used by the plant or sold outside... Help with procuring economics

   of CCU equipment

■ Basic Materials Research Chief Hwang Min-jae, “CCU application will be continuously expanded to achieve carbon   

    neutrality”… “R&D will be carried out continuously to expand LOTTE Chemical’s gas separator CCU technologies”

LOTTE Chemical announced that it has begun development of highly pure nitrogen production technologies using gas separator CCU (Carbon Capture, Utilization) on the 2nd.

LOTTE Chemical and LOTTE Construction agreed to pursue mutually organic cooperation based on the core capacities and technologies possessed by each company through an MOU for developing highly pure nitrogen production technology using carbon capturing gas separators by the LOTTE Construction Technology Research Institute on the 27th. The event was joined by LOTTE Chemical Basic Materials Research Chief Hwang Min-jae, Innovation Center Chief Choi Young-heon, LOTTE Construction Technology Research Institute Director Kim Geum-yong, and Technology Research Planning Team Leader Seok Won-gyun. 

Through this MOU, the two companies will pursue ▲highly pure nitrogen production process development, ▲installation and operation of testing facilities, ▲green certification, and ▲application of commercialization.

Exhaust gas is generated when manufacturing products in the petrochemical process, and CCU technologies refer to the technology for collecting regularly discharged exhaust gas to separate and utilize carbon dioxide. Exhaust gas also includes carbon dioxide, but also contains about 70% of nitrogen. LOTTE Chemical plans to gather the nitrogen included in exhaust gas to make it highly pure for utilization. Plans are to improve economic efficiency as well when installing CCU equipment later with the said technologies.

Nitrogen is often injected in work related to process activation or repairs in petrochemicals. LOTTE Chemical also currently uses nitrogen for equipment sealing, pipe purging, drying, etc. Nitrogen is also used in a variety of other areas such as production of steel and steel products, automobile and electronic device welding, food packaging, etc. LOTTE Chemical plans to use nitrogen procured through the highly pure production process at its plant or sell the nitrogen.

LOTTE Chemical Basic Materials Research Chief Hwang Min-jae stated, “CCU application will be continuously expanded to achieve carbon neutrality,” adding, “R&D will be carried out continuously to expand LOTTE Chemical’s gas separator CCU technologies.”

LOTTE Construction Technology Research Institute Director Kim Geum-yong commented, “Through this MOU, we now have the opportunity to strengthen the technology capacities and cooperation of the two companies to respond to climate change,” and added, “We will find new projects and increase investments for carbon neutrality.”

Meanwhile, in March of this year, LOTTE Chemical installed gas separator CCU pilot facilities for the first time among domestic chemical companies at Yeosu Plant 1 and conducted test operations for nine months. Through this, performance verification of carbon capture gas separator was completed, and it is pursuing commercialization of the separator carbon capture for the first time among global companies at the Daesan Plant based on the data and operating technologies collected and analyzed during the testing process.
