The collector/distributor is equipped with a receiver pipe with offsets that provide the optimal collection and distribution of gas or liquid. These devices have a variety of designs based on a central manifold and distribution taps. Depending on the requirements of the project and reactor’s geometry, perforated pipes, triangular wire slit cylinders, mesh screens, distribution nozzles, etc. are used. The devices are dismountable for ease of installation through the hatch. Different parts are connected to each other using fasteners. Gaskets are made of ceramic fiber or thermally expanded graphite.
