ISO 2016 All rights reserved vBS EN ISO 17349:2016ISO 17349:2016(E)IntroductionIn recent years, the oil industry has been facing challenges in developing and operating high-CO2content of
30、fshore fields. The CO2-rich streams, separated from the produced natural gas, can be injected to enhance oil recovery from the reservoirs. Even in cases where the oil recovery increase is not so significant, operators have to consider the CO2-rich stream compression and injection, in order to avoid
31、its venting to the atmosphere.Main concerns comprise surface safety system and material selection areas, which lack specific standards and regulations for this scenario. The commercial tools available, for instance, to model the dispersion of gases, need to be validated for CO2and CO2/hydrocarbon mi
32、xtures, which have distinctive thermodynamic behaviour. This will affect the choice of materials and plant design.This International Standard addresses concepts and criteria for processing CO2-rich streams, as a supplement to existing standards for offshore installations.vi ISO 2016 All rights reser
