Method to remove organic halogenated molecules from gaseous currents and relative plant |
摘要 |
Method to remove organic halogenated molecules from gaseous currents arriving as a residue of industrial working processes or not, the gaseous current being delivered into a reactor (16) containing a fluid bed consisting of at least one solid adsorbent element after having undergone at least one filtration followed by a cooling, the gaseous current cooperating with the solid particles with exchange by adsorption between the gaseous current and the solid particles, the reactor (16) achieving a time of contact between the gaseous current and the solid particles at least longer than 3 seconds, the gaseous current which enters the reactor (16) having a temperature lower than 80 DEG C., but advantageously between 30 DEG and 70 DEG C., the cooling of the gaseous current upstream of the reactor (16) being followed by a gas/water or gas/air heat exchanger (13). A plant to carry out the above method includes a reactor having a first input zone (17) and a second zone of exchange by adsorption between the gaseous current and a solid support in the form of fluid-bed particles kept in suspension, and a distribution plate (18) to introduce and distribute the gaseous current defining the second zone of the reactor (16), the reactor (16) having dimensions such as to achieve a passage time at least longer than 3 seconds, the concentration of solid support within the reactor (16) being between 0.1 and 0.5 kg per each cubic meter of gaseous substance.
