The impact of tower internals on packing performance

The overall tower performance is influenced by the type of both tower internals and random packing. The Raschig GmbH`s most recent development is the Raschig Super-Ring®, the fourth generation of random packings. In 1998, the Raschig Super-Ring No. 2 was tested at the facilities of Fractional Research Inc. A significantly improved capacity and pressure drop over other random packing was observed without reducing the efficiency. A recent retesting of Raschig Super-Ring No.2 using new tower internals revealed that the revised tower internals further improved the performance. Raschig has noticeable experience in designing liquid distributors.
