.... For engineering studies it is important that CO 2 streams containing H 2 S and hydrocarbons be evaluated for their miscible flooding potential. It is also important to evaluate the effects of CO 2 and C 5 + components in rich gas mixtures to determine whether they can be used to reduce calculated enrichment...
