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
