    Abstract: A method for separating a C4 olefin from a mixture gas comprising C4 olefin and paraffin, and its apparatus are provided to minimize the concentration of isobutane in a C4 olefin and to increase the concentration of a C4 olefin. A method for separating a C4 olefin from a mixture gas comprising C4 olefin and paraffin comprises the steps of introducing a mixture gas comprising C4 olefin and paraffin into an adsorption tower to adsorb an olefin to separate paraffin and a desorbing agent; introducing some of the high purity C4 olefin into an adsorption tower to wash out a small amount of the paraffin adsorbed together with an olefin to increase the purity of olefin; and introducing a desorbing agent to the adsorption tower to desorb and separate an olefin, wherein the continuous adsorption, washing and desorption are carried out at three adsorption towers.

    Abstract: PURPOSE: Disclosed is a treatment method of volatile petrochemical compounds by adsorption. CONSTITUTION: The equipment for adsorption is composed of an adsorption tower (11) packed with silica gel and activated carbon, adsorption recovery tower (12,13), a heat exchanger (14), a storage (15), and a vacuum pump. In the adsorption tower (11), the silica gel adsorbs the stronger adsorbable compounds such as pentene, hexane, or heptane and activated carbon does the weaker adsorbable compound such as methane, ethane, propane, butane, or pentane. The adsorbing process operates at 15-50 deg.C and 30-100 mmHg. The adsorption recovery tower (12,13) is carried out by the one process period of compression, adsorption, decompression, and pressing-cleaning. The recovery tower is operated at pressure of between 30 and 1000 mmHg by operation of vacuum pump. And, the heat exchanger (14) is operated at 1200-1800 mmHg.
