FEIZHOU 13X Molecular sieve can Removal of CO2 from Natural Gas Using Membrane Separation System Modeling and Process Design

Natural Gas (NG) processing is one of the major industrial separation processes. Membrane process, a relatively new technology among other available techniques, can be 

used for the removal of impurities like carbon dioxide from NG. Membrane performance has been described by different mathematical models over the decades. In this work, a 

simple mathematical model has been suggested to be incorporated with ASPEN HYSYS in order to design the membrane system for CO2/CH4 separation. Parameter sensitivities were analyzed by changing the operating conditions, such as feed composition and pressure and membrane properties (including selectivity of the membrane). Moreover, different configurations have been investigated for the optimized design including single stage (with and without recycle) and double stage membrane systems. It is shown that methane recovery can be improved by recycling permeate stream as well as by using double stage membrane system.

13X-2 is used for cryogenic air separation. The adsorption capacity for CO2 and H2O has been futher improved.It has good performance even when CO2 content is low.In the 

same pressure, the CO2 adsorption capacity is about 22% higher than normal 13X.

Typical Applications：

Removal of water and CO2 in cryogenic air sepatation system. 

Low regeneration temperature.
