It is designed to prevent flow maldistribution in the bed and to avoid movement of the catalyst bed by high-velocity impingement. Inlet Diffuser reduces kinetic energy of feed to ensure that the distribution of feed inside reactor or in the Distributor Tray below is not turbulence directly from the inlet […]

In two phase hydroprocessing reactors with quench in inter-bed, a mixing device is required in order to contact the quench fluid with vapor and liquid media from above catalyst bed for efficient transfer phenomena with uniform composition and temperature profiles in the bed below.

Support Grids are designed to provide sufficient strength to support catalytic beds under normal operating conditions while at the same time without creating any capacity restriction in the column, a suitable support grid selection depends on the type of catalyst as well as maximum design load. The Support Grids surface […]

In the hydroprocessing reactor, the hydrocarbon feed is reacted with hydrogen over a fixed bed of catalyst at an elevated temperature and pressure. For petroleum fractions heavier than naphtha, the mixture of hydrocarbon feed and hydrogen typically consists of two phases: a liquid phase and a vapor phase. In order […]

A series of cylindrical screens arrayed at the top of the upper catalyst bed either to collect metallic contaminates or scales from plugins the top surface of the upper catalyst bed or to increase the total surface area of the upper catalyst bed to extend the bed’s useful life.
