Air Products has completed the manufacturing of a carbon monoxide (CO) coldbox at its cryogenic equipment manufacturing facility in Caojing, Shanghai.

The coldbox has been manufactured for Yangzi Petrochemical Corporation, a subsidiary of Sinopec Corporation and one of the largest crude oil and petrochemical companies in China and Asia.

Weighing over 300 tons and measuring over 70,000 cubic feet, the coldbox will produce over 300,000 tons of CO every year.

It is the largest CO coldbox and the largest workshop-built CO coldbox that Air Products has ever constructed for its customers globally.

Yangzi Petrochemical will use the CO in its 500,000 ton per year acetic acid factory.

In addition to CO, the coldbox will produce hydrogen and syngas, a mix of carbon monoxide and hydrogen, to produce methanol, fuel, acetic acid and other products.

Li Bing, General Manager of Air Products’ Caojing Manufacturing facility said, “We have already built many oxygen and nitrogen coldboxes for our customers throughout Asia.

The CO coldbox for Yangzi Petrochemical is a new milestone for us in scale, scope and technologies.”

Air Products will ship the CO coldbox via the Yangtze River and work with Yangzi Petrochemical for the road transportation to deliver the coldbox to its facility at the Nanjing Petrochemical Complex in Jiangsu Province.
