摘要： 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.

摘要： 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.

摘要： (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.

摘要： Abatement systems are used to remove harmful pollutants resulting from manufacturing processes. Prior art abatement systems can dangerously back-flash due to, for example, changes in gas velocity and if the inlets become constricted due to clogs. To prevent back-flash a sprayer is introduced to an inlet of the abatement system. The sprayer sprays a volume of a cooling liquid, such as water, into the inlet. In the event of a back-flash, the liquid can extinguish the flame, preventing further damage to the abatement system. The sprayed liquid can provide further benefits, such as cooling the incoming, mitigating effects of reactions within the cooling gases, and flushing away solid particles that would otherwise clog the inlet. These further benefits can allow the abatement system to safely handle additional gases and larger volumes of incoming gas.
