Chemicals, Oil and Gas Industry

Most CO2 sources arise from a reaction to form a by-product of another process. With these sources and the availability of large amounts of raw CO2 gas the chemical and industrial gas industries can look to recover, process and liquefy CO2 for their own use or marketing purposes.

ASCO offers various possibilties of recovering CO2 from chemical and thermal processes as well as from burning processes.

Our experts will be pleased to provide advice in choosing the most economical solution.


CO2 By-Product Recovery Plant (BPR)

Be it from an alcoholic fermentation process, other industrial sources (e.g. ammonia or ethylene oxide production) or natural sources, ASCO finds your individual CO2 recovery solution.

The high-purity source with a CO2 concentration of > 95 % is the base for a high-economical CO2 production. Depending on this source the CO2 requires certain types of purification, before it is compressed and liquefied to become ISBT quality and is then stored in a designated tank.


CO2 Stack Gas Recovery Plant (SGR)

The CO2 stack gas recovery plant enables to recover CO2 from flue gas production of boilers or other flue gas sources.

The flue gas is separated from sulphur compound in a CO2 washer (scrubber) before it is transported into the absorber where it is absorbed by the specially formulated ASCOSORB solvent. This ASCOSORB solvent is heated by the steam-controlled reboiler in order to separate the CO2 gas again.


CO2 Production Plant (CPS)

This technology is based on the absorption of CO2 from stack gas into an aqueous monoethanolamine solution with the subsequent separation process by heating with a steam-controlled reboiler. The required CO2 quality according to the ISBT standards is reached after compression and liquefaction.
