scope:

This International Standard contains provisions for design of topside facilities for offshore plants handling CO₂-rich streams at high pressures; i.e. CO₂ molar concentration above 10 %. The surface systems include usual offshore process unit operations, as shown in Figure 1.

This International Standard is applicable only to topside facilities of fixed and floating oil and gas production offshore units up to the last barrier, such as an ESDV. Subsea production systems and Cryogenic CO₂ separation are not covered.
