ABSTRACT:
A high purity isobutane adsorption separation and purification apparatus is provided including a pressure regulator which regulates the pressure of an isobutane-containing gas; the at least one adsorption bed packed with zeolite 5A and carbon molecular sieve arranged downstream of and operatively associated with the pressure regulator; a flow control valve disposed between the pressure regulator and the at least one adsorption bed; a surge tank operatively associated with and for receiving a purified isobutane product from the at least one adsorption bed; a vacuum pump operatively associated with and for removal of impurities from the at least one adsorption bed; and valves disposed between the pressure regulator and the at least one adsorption bed, between the at least one adsorption bed and the surge tank, and between the at least one adsorption bed and the vacuum pump. An adsorptive separation and isobutane purification process is also provided which may be used with the apparatus of the invention.
