Recycling of Cold Drainage (Diamond Water) Brings Mutual Benefit and Common Prosperity
冷排水循環再利用 結合在地互利共榮
CPC Corporation, Taiwan
Diamond water is both tangible and intangible to aquafarm owners as it creates a highquality
living environment for grouper and improves the survival rate of farmed fish
while also developing local industries as well as the reputation of Taiwan’s Grouper
Kingdom.
INTRODUCTION
In response to the government’s policy of expanding the use of natural gas, the Company adheres to the core goal of implementing energy resource integration and achieving circular economy. When the Company imports natural gas, suppliers will first compress it into liquefied natural gas (LNG) by lowering the temperature to 162°C below zero. After LNG is delivered to Taiwan, temperature exchange with seawater takes place to gasify LNG before it is ready for consumer consumption. A great deal of cold energy will be released during gastification, apart from using it to cold energy air liquefaction, cold energy power generation, cold energy chiller system, air separation, the Company also provides local aquafarm owners with low-temperature water to breed high-economic value fishes. Through the application of the diversified cold energy project allocation and the common prosperity of the community and industry can achieve the benefits of circular economy.
FRAMEWORK AND STRATEGY
Since 2005, the Company has provided clean and lowtemperature of cold drainage to the Kaohsiung Yongan Fishpond free of charge. Cold drainage is filtered and cleansed three times before being discharged to create a quality environment for the grouper, reduce the possibility of diseases, and thus enhance output. Therefore, aquafarm owners call the cold drainage as diamond water. The Company has benefited the local fishermen and helped organised the Yongan Grouper Festival every year. The high-quality grouper competition promotes the characteristics of the local industry with practical actions. Green Technology Research Institute of the Company further utilises the advantages of cold drainage, and cooperates with four sectors of production, government, academia and private sector to carry out the cultivation of seaweed, sea fungus, sea urchin, abalone, and develop food, sea fungus gift boxes, and health care medical products. The Company established the best model of mutual benefit, symbiosis and common prosperity.ACHIEVEMENT AND IMPACT
The Company supplies free cold water discharged from the LNG process to local aquafarms through underground box culverts. Apart from the ease of access, aquafarm owners do not need to worry about the possibility of barnacles clogging the intake or typhoons damaging the pipelines. Aquafarm owners are able to save on expenses from electricity for pumping water, maintaining, repairing, or restoring pumping equipment. Diamond water is both tangible and intangible benefits to aquafarm owners. It creates a high-quality living environment for grouper and improves the survival rate of farmed fish, also creating an annual output value of about NT2 billion dollars, and promotes the development of local industries as well as the reputation of Taiwan’s Grouper Kingdom. Meanwhile, It reduces carbon dioxide emissions by approximately 2,780 tons per year.FUTURE DIRECTION
In the future, the Company will increase the proportion of cold drainage supply and will cooperate with the government to install more water transportation pipes in order to expand the benefits to neighbouring towns, and will continue to counsel fishermen to participate in the cultivation of cold-drained fishes and algae. In addition, the Yongan LNG Cold Discharge Water Aquaculture Test Farm of the Fisheries Agency, Council of Agriculture, was unveiled to promote fisheries transformation with innovative aquaculture technologies, in order to boost marine economic growth. The Company will also promote academic research, in hopes to make good use of cold energy resources and implement the circular economy as well as contribute to energy conservation, carbon reduction and environmental protection, while taking into account the development of local industries, local employment and prosperity.
