Abstract
The problem of trapping solid particles in a production line with dehydrogenation of C4–C5isoparaffins to iso-olefins in a fluidized catalyst bed was considered. Dust collection of fine catalyst particles for paraffin dehydrogenation units using a standard TsN-15 cyclone and a new dust collector (NDC) with arc-shaped elements was studied. The results of numerical simulation of TsN-15 and NDC were presented. Comparative studies showed NDC to be more efficient than TsN-15 for trapping fine solid particles with sizes of less than 20 μm. The pressure and flow velocity profiles for NDC were shown to change as a regular tendency, without any critical deviations. The gas flow velocity through the arc-shaped NDC elements was shown to be stable in contrast to TsN-15, which creates high flow velocities at the cyclone periphery to increase the probability of dust breakthrough into the flow.
