Nitrous Oxide Monitoring for Greenhouse Gas Reduction

Greenhouse gases (GHG), which are considered to be one of the causes of the global warming, include carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and fluorinated gases.

In particular, various industries are required to reduce and manage the N₂O emissions, which impact on the warming the atmosphere is 298 times that of CO₂.

For example, sewage treatment plants generate N₂O during sludge incineration treatment and during wastewater treatment in raw-water tanks and sludge storage tanks. Meanwhile, industrial waste treatment plants and garbage disposal plants generate N₂O during incineration. Although N₂O reduction has become increasingly common by adoption the latest equipment such as pyrolysis gasifying treatment, further reduction of N₂O emissions is required through proactive monitoring.

Voice of Facility Management and Plant Manufacturers

Need to monitor N₂O continuously and at high accuracy 24 hours a day, 365 days a year

　► Sewage treatment facilities

　 - Sludge incineration: high-temperature cyclone, exhaust gas from stack

　 - Water discharge: raw-water tank, sludge storage tank

　► Incineration facilities at industrial waste treatment plants and garbage disposal plants

　 - Fluidized-bed-type incineration system

► Manufacturing facilities at chemical plants

- Production of nitric acid from ammonia

Voice of R&D Managers

Setup of analyzer needs to be easy to operate for R&D of N₂O
Need to be able to conduct N₂O research and studies in the field and in the lab

　► Various research and development departments
