Iwatani Corporation has increased its competitiveness in the market with a second CO2 recovery and purification plant from Union Engineering that has recently been put into operation.
Iwatani is a major player in the gases industry with a range of projects under development in Japan as well as in the rest of South East Asia. The new plant is part of its effort to further strengthen its position as a leading supplier of highly pure CO2 in China.
The CO2 containing by-products stream from ethylene oxide and ethylene glycol production is often emitted to atmosphere; by implementing a Union Engineering CO2 plant this waste gas can be purified to highly pure CO2 and turned into a profitable business.
Mr. OOYA FUMIAKI, of Iwatani Corporation, commented, “In view of technology, Union can provide [a] sophisticated process, high quality product, material consumption and energy consumption are on the advanced level wherever in domestic and abroad…Union plant will increase our competitiveness in market.”
“We regard any product or technical development that can resolve, mitigate, or reduce environmental impact as ‘Eco-friendly Products’. This business case fits perfectly into our strategy and Union Engineering was the natural choice as partner to realise the project.”
A profitable business
The modern day ethylene oxide plant is a highly efficient process plant designed to minimise energy use and waste generation. However, due to the nature of the process, carbon dioxide is generated as a by-product during the oxidation process.
“…rather than releasing this naturally stored CO2 to the atmosphere we see a trend that moves towards recovery of CO2 from CO2 rich by-products streams from a range of industrial processes. This trend creates a win-win solution for all partners involved”
Liu Peng, Union Engineering in China
In most instances this highly concentrated stream of carbon dioxide is considered a waste product and emitted to the atmosphere.
By integrating a CO2 purification and liquefaction unit into the plant this can turn the waste stream into a profitable business by converting the gas into a highly pure CO2 to be used in food and beverage applications.
Sales Manager Liu Peng, Union Engineering in China, explained, “CO2 is a product with still increasing demand. In China a large amount of the CO2 used for food and beverage applications are produced from natural CO2 wells.”
“However, rather than releasing this naturally stored CO2 to the atmosphere we see a trend that moves towards recovery of CO2 from CO2 rich by-products streams from a range of industrial processes. This trend creates a win-win solution for all partners involved, the environment considered one of them.”
Union Engineering is the world leader in CO2 technology, headquartered in Denmark and with sales and service offices in Brazil, China, Dubai, Singapore and the US.
