HiDur® Inert Balls - Random packings

HiDur® Inert Balls are the simplest, regular formed type of random packing, with relatively small surface area per packed volume. Due to the low void fraction, pressure drop is quite high.

HiDur® Inert Balls are mainly used as catalyst carriers and flow straighteners at refineries and other petrochemical industries.

Checklist important parameters

Listed below are a number of parameters that are important to consider when selecting the right type and size of random packing in order to achieve an effective and sustainable solution.

Sometimes it is difficult or even impossible to obtain information and data regarding the specific process. Together with our suppliers, we have extensive experience and we can make sound assumptions as a basis for designing the best solution for the process.
