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.

Abstract:
The present invention relates to a system for manufacturing a hydrocarbon compound by using Fischer-Tropsch synthesis. A catalyst reduction reactor of the present invention in the system for manufacturing the hydrocarbon compound by using the Fischer-Tropsch synthesis comprises a mixer into which an iron-based catalyst is charged, a first synthetic gas is injected for reducing the iron-based catalyst, and into which a second synthetic gas is injected so as to be mixed with the reduced iron-based catalyst. As a result, a catalyst is reduced (activated) in a separate reactor and then introduced into the Fischer-Tropsch reactor thereby facilitating introduction of an additional catalyst when manufacturing the hydrocarbon compound using the Fischer-Tropsch synthesis, and reducing the time required for manufacturing.
Abstract:
PURPOSE: An apparatus for simultaneous production of synthetic oil and electricity is provided to synthesize synthetic oil by supplying synthetic gas to a Fischer-Tropsch synthesis reactor unit. CONSTITUTION: A steam methane modifier(1) generates a synthetic gas with a H2/CO ratio of 3:1 or more by modifying supplied natural gas. A first and a second heat exchanger(21,22) are installed in a heat exchanger supply pipe(2), to supply high temperature synthetic gas to a pressure-changing absorption separator(3). The pressure-changing absorption separator separates the synthetic gas into a synthetic gas with H2/CO ratio of 2:1, and high purity hydrogen, and supplies the same to a synthetic gas supply pipe and high purity hydrogen supply pipe, respectively. A Fischer-Tropsch synthesis reactor unit generates electricity by using the high purity hydrogen. A methane heat exchange supply pipe(6) has a third heat exchanger(61) to increase the temperature of methane, and supplies the methane.
