WorleyParsons has been awarded the basic design and detailed design contract for China National Offshore Oil Corporation (CNOOC) LNG Cold Energy Air Separation Unit (ASU) Project. Located in Ningbo, China, it will be capable of producing more than 600 tons per day of liquid oxygen, nitrogen and argon.
"We are very excited to be working with CNOC in this first of a kind ASU project in China. This project will enable us to strengthen our position as the leading procurement and construction management (EPCM) service provider in China," said Mr Karl Qiu, President of WorleyParsons China.
The facility is designed to liquefy air at low temperatures by using cold energy recovered during the LNG re-gasification process, to produce industrial gas products.
The facility brings environmental and energy efficiency benefits compared to conventional processes, saving as much as 50 per cent of the conventional energy requirements by using the LNG cold energy to achieve liquefaction and to produce chilled glycol. The chilled glycol displaces the cooling water utility previously used for air compression in the ASU plant, thereby also conserving water resources. Additionally, the use of LNG cold energy technology decreases carbon dioxide emissions by reducing electrical use in operation of the ASU.
