Succeed at Plant Debottlenecking

noemail@gtchouston.com — Tue, 01 Apr 2008 13:00:00 GMT

You are a chemical engineer with the modest assignment to debottleneck your plant to boost production. The direct approach seems obvious: assess current capacity, determine output limitations, and then vigorously employ standard engineering techniques to upgrade or replace equipment. Perhaps you find 20% reserve capacity eliminating the need for major capital expenditure. Even if you achieve good results, however, you cant necessarily be sure that your straightforward analysis gives the optimum solution. Now, consider a different assignment: expand the plant capacity by 75%, reduce the specific energy consumption by 20%, increase the product yield by 5% - and do it on a shoestring budget. This presents more of a challenge and definitely requires a different, more creative approach to the problem. Not every plant can be revamped to gain such improvements. However, many plants can operate much more efficiently or at a substantially higher capacity than a routine analysis might...

Pyrolysis Value Upgrade with GT-Styrene®

noemail@gtchouston.com — Sun, 02 Mar 2008 18:00:00 GMT

When new petrochemical capacity for ethylene or derivatives is considered, most investors give relatively little attention to the optimum scheme for processing the pyrolysis gasoline (pygas) byproduct. Pygas operators will usually recover the benzene and possibly the toluene from the C6 + stream, but will rarely extract other components. Recent advances in separations technology make it possible to recover high-purity styrene and isomer-quality mixed xylenes from the pygas as well, at a significant upgrade over their alternate disposition into motor fuel. The typical view is that this area of the plant is a required treatment center, so that the bulk of the material can be blended into motor gasoline. Rather than merely coping with the requirements, it is possible to design the pygas processing area to generate substantial additional income from the petrochemicals contained in this stream. Optimization Scope for Pygas Treatment Schemes Inherent inefficiencies and missed...

Extractive Distillation Applied

noemail@gtchouston.com — Sun, 02 Mar 2008 17:00:00 GMT

Extractive distillation (the use of a solvent in distillation to enhance the separation efficiency) is recognized throughout the academic world as a useful means to separate close-boiling mixtures. In recent years, this method has gained widespread acceptance among industrial users. This article will describe how Extractive Distillation (ED) technology can be applied to three important commercial applications to improve profitability of the petrochemical and refining industry. These are: BTX recovery and purification from aromatics-containing feedstocks Styrene recovery from pyrolysis gasoline Sulfur removal from cracked gasoline stock What Is ED? Extractive distillation is a vapor-liquid process operation that uses a third component, or solvent, to effect a chemical separation. The extractive agent creates or enhances the volatility difference between the components to be separated. The extractive agent and the less volatile component flow to the bottom of the...

GTC Technology to Expand Technology Portfolio

noemail@gtchouston.com — Thu, 20 Mar 2008 13:00:00 GMT

Houston, March 20, 2008 - GTC Technology today announced the expansion of their technology portfolio to include GT-BenZap^sm, a benzene saturation process. This new technology was designed as a low cost alternative for lower-capacity refineries, to enable them to comply with EPA’s mobile source air toxics regulations (MSAT II). GT-BenZap^sm offers a simple solution through hydroprocessing, and can be adapted to retrofit existing refinery units.

“Normally we advocate benzene extraction and recovery to meet the new MSAT II regulations, however we have found that in some situations depending on scale or supply chain logistics, benzene saturation is desirable. GTC can work with customers on either extraction or saturation to solve this problem. In addition, GTC can supply modular construction options to speed implementation,” said Ron Cormier, Director of Business Development.

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.
