Carbon monoxide (CO) is a colourless, odourless poisonous gas and has a special significance as a raw material for the chemical industry.
Pure CO is primarily required for the production of:
acetic acid
polyurethane
polycarbonate
formic acid
phosgene
Processes for Manufacturing Carbon Monoxide
CO is generated by reforming hydrocarbon-content feed stocks as natural gas, mineral oil fractions or coal and always comes about in conjunction with hydrogen in mixture ratios characterized by the C/H ratio of the individual feed stocks.
All processes supplied by LE (Linde Engineering) for the extraction of CO are largely based on the company's own technologies, supported by licenses, if required.

With 75 plants world wide for the production of H2/CO, planned and installed by Linde – 17 of which are also operated by Linde – as well as just as many cold boxes for the recovery of CO, Linde is one of the leading contractors in this business segment.
Linde plants provide CO with a purity of up to 99.99 vol.-% and a capacity from 100 Nm3/h to over 30,000 Nm3/h.
