Static Bed Concentrators • DEC.SBC™

DEC.SBC™ (static bed concentrator) is a type of air pollution control device used to remove volatile organic compounds (VOCs) from air streams. SBCs work by passing the contaminated air stream through a bed of adsorbent material, such as activated carbon or zeolite, so the VOCs are adsorbed onto the adsorbent material while the clean air stream is exhausted to the atmosphere.

DEC.SBC™ is the ideal process for treating large volumes of air with a small concentration of solvents, typically 0.1÷0.5 g/Nm³. It is not usually considered an alternative to LEL recirculation systems (DEC.LEL™), which are designed for different concentration and flow profiles.

Once desorbed from the adsorbent bed, the concentrated VOC stream can be efficiently treated in a downstream VOC treatment system, such as a solvent recovery unit or thermal oxidizer.

DEC.SBC™, DEC.RBC™, and DEC.FBC™ are all part of DEC's XBC™ concentration systems family, differing in how the adsorbent bed is configured: static (fixed), rotary (wheel), or fluidized. The right configuration depends on air flow rate, solvent concentration, and the specific process requirements of the application.
