DuPont Clean Technologies (DuPont), the supplier of scrubbing and other environmental technologies, has introduced a new, advanced steam plume suppression solution for its MECS® DynaWave® scrubbers in SRU applications.
Called Sennuba, the technology employs two heat exchangers and a heat transfer medium to heat stack gas from the wet scrubbers, that are used to remove pollutants from flue gases, with steam produced with the heat of the gas at the inlet of those scrubbers. This solution avoids the high operating costs associated with other methods of steam plume control, as it recovers otherwise lost heat from the process to generate the necessary steam to suppress the visible plume. Sennuba is designed with a heat transfer medium so there is no chance of leakage of the process gas directly to the stack gas. In this design, there is no forced circulation of the heat transfer medium.
