An industrial refrigeration project with hydrocarbon refrigerant was introduced in a recent publication of the Japanese Government. The highly efficient system helps reduce CO2 emissions by more than 320,000 kg CO2 annually.
The Ministry of the Environment of Japan (MOEJ) recently published a pamphlet introducing 9 exemplary projects using natural refrigerant technologies in different applications in Japan. The MOEJ has been providing financial assistance to projects introducing energy-efficient freezing/refrigeration equipment that uses natural refrigerants. The scheme applies for reducing direct and indirect CO2 emissions when renewing the existing facility or building a new facility.
Below you can find a summary of an industrial refrigeration project with a propylene refrigerant (R1270) based system.
New-generation chemical plant freezing unit with R1270
At a polypropylene production plan in the South of Japan, a 30 year old absorption freezing unit was replaced with a new freezing unit that uses propylene as a refrigerant. The propylene-based system with a cooling capacity of 612 kW consists of cooling tower, cooling water pump, water-cooled propylene chiller unit and cold water tank.
When compared to a R407C based cooling facility, the propylene system reduces CO2 emissions by 312 tonnes annually due improved energy efficiency. Additional 17.1 tonnes of CO2 reduction is related to avoided refrigerant leakage.
Subsidiary rules
The project received support from the MOEJ subsidy program between the fiscal years 2008 and 2012 with the following rules:

The project received support from the MOEJ subsidy program between the fiscal years 2008 and 2012 with the following rules:
- Eligible applicants for subsidy: Private companies
- Projects eligible for subsidy: Projects to introduce energy efficient freezing and/or refrigeration equipment that uses natural refrigerants
- Subsidization ratio: A maximum of 1/3 of the cost incurred for the introduction of the eligible equipment that is incremental to the cost of the comparable HFC-based equipment, including the installation cost
