Gas Distributor
From a process standpoint, the most important column internals are the liquid distributors. A liquid distributor is required at all locations in the column where an external liquid stream is introduced. In addition to providing a uniform liquid distribution pattern to the top of the packed bed, the distributor must provide sufficient gas passage area to avoid a high-pressure drop or liquid entrainment. The liquid distributor should have a high turndown ratio and be resistant to fouling. The table listed below gives some conventional distributors.
In large diameter column, the gas cannot distribute equably without gas distributor. For the column diameter less than 2 meters, orifice pipe gas distributor is a simple and efficient gas distributor.
For larger diameter column, the riser type gas distributor is more efficient. Trough-Pan Liquid-Gas Distributor is a patented product of Tianjin University. It has very good operation performance such as low spatial occupying, plug proof and low-pressure drop.
New Type Trough-Pan Liquid-Gas Distributor also has the excellences of preventing leak and easily building in. At present, Trough-Pan Liquid-Gas Distributor is one of the internal distributing set that is the most extensively used.
