GT-BTX PluSSM

Sun, 15 Jun 2008 15:58:22 GMT

GT-BTX PluS^SM is a variation of GT-BTX® and uses extractive distillation technology for simultaneous recovery of BTX and thiophenic sulfur species from refinery or petrochemical aromatic-containing streams. The technology is useful to produce low sulfur gasoline meeting the 10ppm limit of sulfur, without change in octane value. An alternative use of GT-BTXPluS^SM is to generate a large volume of aromatics useful to produce paraxylene, without the requirement of a typical naphtha reformer unit. The process is especially attractive for use with feedstocks that have been produced from high severity FCC operations.

The process is optimally installed on the FCC mid-cut naphtha stream. GT-BTX PluS^SM removes all thiophenes and partially the mercaptan species from the FCC gasoline feed. The olefin-rich raffinate can be sent directly to the gasoline pool for blending, or to a caustic treating unit to remove the mercaptan-type sulfur compounds before being sent to the gasoline. The desulfurized aromatics extract stream can be directly fed into petrochemical production units instead of recycling to the naptha reformer. GT-BTX PluS^SM provides an excellent solution to meet today's clean gasoline requirement, as well as to convert lower-value gasoline components into higher-value petrochemicals.

Advantages:

Produces high-quality aromatics from FCC gasoline.
Reduces the sulfur content of the FCC gasoline fraction being sent to the gasoline pool
Reduces H2 consumption, only HDS function is required for thiophenic sulfur
No olefin saturation
Greater utilization of naphtha reformer compared to units which recycle the cracked gasoline. Avoids BTX taking a "free ride" through the unit
Opportunity to feed more fresh naphtha and generate more hydrogen.

Process Equipment Technology - Column Internals

Fri, 09 May 2008 17:17:07 GMT

The importance of column internal design is often overlooked in most packed column designs. GTC offers a wide range of GT-SMART^TMcolumn 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

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

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

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

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.

GT-BTX® is GTC's premier aromatics recovery technology that uses extractive distillation (ED) to remove benzene, toluene, and xylene (BTX) from refinery or petrochemical aromatics streams such as catalytic reformate or pyrolysis gasoline. The process is superior to conventional liquid-liquid and other extraction processes in terms of lower capital and operating costs, simplicity of operation, range of feedstock, and solvent performance. GT-BTX® is the most reliable method for grassroots aromatics extraction units and has been applied for revamping all of the established LLE or ED technologies. GT-BTX® is unique in its ability to extract high purity aromatics with nearly complete recovery from 3-carbon boiling range feedstock. This technology is also the optimum choice to meet the gasoline specifications calling for reduced benzene.
