Abstract: A process for treating a petroleum fraction and for efficiently absorbing an organic halogen compound from a fluid mixture of the organic halogen compound and an inorganic halogen compound derived from crude oil. Also disclosed is an improvement in absorption performance of a halogen-compound-absorbing material, thereby reducing the frequency with which the absorbing material is exchanged. The absorbing agent includes attapulgite (palygorskite) having high absorption performance with respect to organic halogen compounds. Also disclosed is an absorption column in which the aforementioned absorbing agent and a halogen-compound-absorbing agent, that includes zinc oxide, are disposed in series, thereby making it possible to raise the treatment performance with respect to a fluid that contains, in high concentrations, the organic halogen compound in addition to the inorganic halogen compound.

Abstract: Disclosed is a method for recovering a volatile organic compound (VOC) using pressure swing adsorption carried out with two beds that includes feeding the VOC to the first bed for adsorption and, while the VOC is being adsorbed by the adsorbent material in the first bed, simultaneously extracting the VOC adsorbed by the adsorbent material in the second bed through executing a desorption step by reducing the pressure of the second bed to cause desorption of the VOC in the adsorbent material of the second bed, executing a reflux step by transferring gas to the second bed and removing the transferred gas from the second bed, and executing a repressurization step by increasing pressure of the second bed to a pressure suitable for adsorption of the VOC by the adsorbent material in the second bed.

Abstract: Provided is a composition for use in fabricating a carbon molecular sieve membrane, including a fluorine-containing polymer matrix and polysilsesquioxane. The composition shows high selectivity to the gas to be separated and high separation quality by controlling the mixing ratio of the fluorine-containing polymer matrix with polysilsesquioxane as well as the type of fluorine-containing polymer matrix and polysilsesquioxane. Ancillary selective pore formation is enhanced by a so-called “autogenous fluorinated gas induced siloxane etching” (A-FISE) mechanism of fluorine-containing polymer/polysilsesquioxane blend precursors during carbonization. Therefore, it is possible to effectively separate gases having a small difference in particle size, which, otherwise, are difficult to be separated with the conventional polymer membranes.

Abstract: (Problem to be Solved)To provide a volatile organic compound recovery device which renders energy saving possible and renders the equipment simple.(Means for Solution)An untreated gas which contains a volatile organic compound is supplied to an adsorption tower (1), whereby the volatile organic compound is adsorbed onto the adsorbent. After completion of the adsorption, a volatile organic compound which has higher adsorbability than that of the volatile organic compound adsorbed onto the adsorbent is supplied to the adsorption tower (1) through a desorption gas supply valve (4). The volatile organic compound which has low-adsorbability and has been adsorbed onto the adsorbent is then desorbed therefrom due to competitive adsorption with the high-adsorbability volatile organic compound fed later, and the high-adsorbability volatile organic compound itself is adsorbed onto the adsorbent instead. As a result, the volatile organic compound which has been adsorbed is discharged from the adsorption tower (1) and recovered.
