DIN EN ISO 17349:2014-11

This International Standard provides guidelines for design of topside facilities for offshore plants handling CO2 rich streams at high pressures. The surface systems include usual offshore process unit operations, e. g. compression, dehydration, hydrocarbon dew point control and CO2 separation. Cryogenic CO2 separation processes are not covered. The actual concentration of CO2 and other components present in the CO2 rich streams is determined case by case, based on reservoir characteristics, topside plant process selection, economical evaluations and appropriate regulations. This standard intends to address concepts and criteria about process with CO2 rich streams that should be considered as a supplement to existing standards for offshore installations. In this document the term 'Streams containing high levels of CO2', henceforth referred to as CO2 rich streams, designates streams with CO2 molar concentration above 10 %. Pure CO2 streams and CO2 streams from combustion processes are not covered. This International Standard is applicable only to topside facilities of fixed and floating oil and gas production offshore units. Subsea production systems are not covered
