New Challenge to Reduce Total Hydrocarbon Losses
10
l Target areas of the SACROC facility for process improvements
l Capitalize on Cynara membranes resistance to hydrocarbon condensation
l Collaborate with customer to address areas of improvement
Strategy
l Maintain current production of high purity CO2 for EOR reinjection while improving the current level of NGL permeate losses

CO2 Membrane Technology in Natural Gas Applications, Future-Forward
l For low CO2 (3 – 15%), high feed pressure (750 – 1,100 psig) applications
l For deep (2,000m) and far (200 – 500 Km) off-shore applications • FPSO and FPU
l For high H2S (1 – 30%) conctent applications • Separation of H2S and CO2 • High H2S (15 – 30%) bulk separation
l For separation of N2 and CH4 l For Helium separation
• High final concentration (99.99%) requirement
