The importance of column internal design is often overlooked in most packed column designs. GTC offers a wide range of GT-SMART^TM column internals which include liquid/vapor distributors, collector trays, and packing supporting/retaining devices that enable our engineers to offer optimal equipment for achieving the desired design targets.

Vapor and liquid distribution are of critical importance to ensure the efficient performance of distillation columns.

Pre-Distributors for flashing feeds are required to control phase separation, momentum, and direction of the fluids.  Varieties of hooded pipes, perforated pipes, vee baffles, and vapor horns are applied as required.

Liquid Distributors are essential in achieving the high quality initial liquid dispersion for packed columns. Gravity or pressure fed distributors are chosen based on the process requirements.  Improved trough distributors are selected for structured packings.  In certain cases, pan type distributors may be used for random packings.

Vapor Distributors are essential to produce optimum vapor to liquid dispersion ratios.  Chimney risers with hats are typical vapor distributors.  High performance vane diffusers are preferred for low pressure drop requirements.

Collector Redistributor Trays are specially designed for transitions and liquid draw requirements.  Features are customized to suit pressure drop, liquid rate gradient, fouling, slurry and other process considerations.
