KR awarded DongHwa Entec and DongHwa Pneutech Approval in Principle (AIP) for the Ammonia Fuel Supply and Re-liquefaction System at Marintec China held on 6 December, 2023 in Shanghai, China.

The Ammonia Fuel Supply and Re-liquefaction System is the result of a Hazard and Operability Analysis (HAZOP) of operation and control with APAVE Korea (ABS Consulting) to identify and improve process hazards and operational issues in advance.

Ammonia has the characteristics of being lighter than air, so it can be effectively controlled in case of gas leakage and has a low explosion potential compared to other fuels. However, it is accompanied by problems of toxicity and corrosiveness, so it is essential that the design addresses these issues.

In response, DongHwa Entec completed the overall process design for the fuel supply, reliquefaction, and neutralization system, considering the unique characteristics of ammonia. Specifically, the core equipment for ammonia reliquefaction is a reciprocating compressor from DongHwa Pneutech.

KR will continue to collaborate with companies developing environmentally friendly technologies to contribute to the global goal of carbon neutrality and will provide ongoing support for successful technology development.
