51st Excellent Environmental Equipment Award: "Energy-Saving Heat Pump Type Ammonia Recovery System" Receives Director-General Award from the Agency for Natural Resources and Energy

We are pleased to announce that the "Energy-Saving Heat Pump Type Ammonia Recovery System" (hereinafter referred to as "this product"), developed by Kimura Chemical Plants Co., Ltd. (hereinafter referred to as "our company"), has received the "Director-General Award from the Agency for Natural Resources and Energy" at the 51st Excellent Environmental Equipment Award, hosted by the Japan Society of Industrial Machinery Manufacturers. The award ceremony was held on March 25, 2026, followed by a presentation of the awarded equipment.

Furthermore, this product also received the "Chairman's Award of the Energy Conservation Center" in the "Products and Business Models" category at the 2024 Energy Conservation Grand Prize (hosted by the Energy Conservation Center, Japan), reaffirming the originality, performance, economic viability, and future potential of our equipment.

🔳Overview of This Product

This product is a system for recovering and reusing ammonia from wastewater containing ammonia generated in chemical, food, and semiconductor factories. It consists of first and second distillation columns, various condensers, a reboiler, and a heat pump. Wastewater is preheated and then supplied to the first distillation column. The generated ammonia vapor is condensed by a heat recovery condenser and sent to the second distillation column for further purification. Finally, ammonia is condensed and absorbed, and recovered as 25wt% ammonia water. The treated water is reused for heating and preheating before being discharged at a low concentration.

Unlike the conventional steam stripping method, this equipment utilizes a heat pump to recover and reuse waste heat, eliminating the need for external steam and achieving high efficiency. As a result, it can reduce primary energy input by approximately 81% and CO2 emissions by approximately 83%.

🔳Future Prospects

Ammonia is widely used as a basic chemical, but it is also discharged in large quantities in low concentrations in wastewater from exhaust gas denitrification processes, and from the semiconductor and chemical fiber industries. Domestic and international production volumes continue to increase, and with stricter environmental standards and the movement towards achieving carbon neutrality by 2050, the importance of efficient recovery technology is growing.

In the future, it is expected that the energy-saving heat pump type ammonia recovery system, which does not emit CO2, will replace conventional inefficient treatment methods such as combustion and dilution. The recovered and concentrated ammonia is expected to be utilized as a decarbonized fuel and hydrogen carrier.

Furthermore, as understanding spreads among chemical, food, and semiconductor manufacturers, as well as engineering companies and trading firms, its adoption is expected to expand, leading to advancements in equipment performance, scaling up, explosion-proof capabilities, and cost reduction.
