    Examples of reactor internals that improve reactor performance by means of reduced fouling and pressure drop build-up include dedicated scale catchers like Topsoe’s proprietary HELPsc that can be installed in the reactor head to capture particulates brought in with the feed before they plug the catalysts beds. Another example would be improved distributor trays with capacity for sediments without obstructing the distribution.

    Continuous development of reactor internals technology will permit use of more complicated feeds in the future. The reactor internals will, in this connection, contribute relatively more to the combined reactor performance. In recent years, some focus areas have targeted renewable feeds fouling and coking potential as well as dealt with the high exotherms. It was necessary to rethink some of the otherwise very successful features used in the ULSD wave and fossil feed processing in general.
