A radial flow reactor vessel is disclosed for use in gas purification, separation or reaction processes and most suitably used in prepurification processes. The reactor has internal baskets for confining a bed of active material. The baskets are rigidly supported at both the top and bottom ends of the reactor and have walls that are axially flexible and radially rigid. The vessel has multiple movable support columns designed to facilitate pre-stressing of the baskets to offset axial compressive loads induced from thermal cycling.

Radial flow reactor with movable supports

A radial flow reactor is disclosed for use in gas purification, separation or reaction processes and most suitably used in prepurification processes. The reactor has two concentric internal baskets which are rigidly supported at both the top and bottom ends of the reactor. The reactor has a removable section in the inner basket to accommodate rotating arms to dense load one or more layers of active materials between the concentric baskets.

Radial flow reactor

A cold isopressing method and mold for compacting a granular ceramic material in which the granular ceramic material is introduced into a cylindrical pressure bearing element of an isopressing mold. The cylindrical pressure bearing element is sufficiently rigid so as to maintain its shape during the introducing of the granular ceramic material. Such element is also sufficiently resilient in a radial direction thereof to deform and bear against the granular ceramic material upon the application of the hydrostatic pressure and to substantially return to its original shape upon the relaxation of the hydrostatic pressure, thereby to allow retraction of the cylindrical pressure bearing element from the granular ceramic material after compaction. In a further aspect, an isopressing method and mold is provided in which the cylindrical pressure bearing element thereof is provided with an enlarged end bore to form an enlarged end section in the finished ceramic tube for sealing purposes.

Cold isopressing method and mold

Particle loader assembly for loading particles into a vessel to form a particle bed comprising inner and outer radially disposed concentric layers of particles the inner layer containing at least one type of particle of different granulometry or composition or both granulometry and composition from a type of particle contained in the outer layer.

Multiple adsorbent loading method and apparatus for a radial flow vessel

The invention comprises particle loader assembly for loading particles into a vessel to form a particle bed comprising inner and outer radially disposed concentric layers of particles said inner layer containing at least one type of particle of different granulometry or composition or both granulometry and composition from a type of particle contained in said outer layer.

An apparatus comprising a rotatable mass of structured packing for mass or heat transfer between two contacting fluids of different densities wherein the packing mass is made up of corrugated sheets of involute shape relative to the axis of the packing mass and form a logarithmic spiral curved counter to the direction of rotation.

Compact contacting device

A uniformly packed bed of adsorbent particles is formed using a particle loader adapted to provide a uniform flow of adsorbent particles across the cross sectional area of an adsorption vessel.
