UIG industrial gases plant supply experience includes carbon dioxide recovery, purification and liquefaction plants on
both
equipment sale and turnkey basis where, in addition to core process equipment,
UIG supplied carbon dioxide storage tanks,
installation, startup, operations, maintenance and product marketing/ sales services.
Capturing and producing
carbon dioxide as a commercial product requires that it be recovered and
purified from a relatively high-volume, CO2-rich gas stream;
typically streams which contain a high percentage of carbon dioxide created as a byproduct.
The most common sources of carbon dioxide feedstock to commercially viable
liquid carbon dioxide plants are hydrogen plants, ammonia plants,
corn-to-ethanol plants, and breweries.
Removal of carbon
dioxide from combustion process stack
gases (process heaters, boilers or power plants)
may be required for environmental reasons, but such sources are not good candidates for commercial recovery due to the low
concentration of CO2 in the source gas and the presence of undesirable compounds which
may create taste, odor, or even health issues if not completely removed.
