  BTEX Removal
 

SouthTex Treaters has patented technology available to remove/dispose of BTEX (Benzene, Toluene, Ethylbenzene, and Xylene) components and aromatics from amine plant vent streams. Our approach to BTEX and aromatic removal costs a fraction of alternative technologies, and is virtually maintenance free.

amine vent stream - btex removalAmines pick up BTEX, along with carbon dioxide. Depending on hydrocarbon content, the BTEX percentages can be high enough on the inlet gas stream that it exceeds the 25 ton permit on the outlet when the CO2 is released again. Our patented process has to do with removing that BTEX, putting it into the fuel system, and burning it so that it’s not a waste of BTU.

Paul Morrow CEO of SouthTex Treaters explains how the patented technology came about by exercising integrity. “When we were building a processing, treating plant for ourselves and basically felt we would fall short to initiate the BTEX within the state permit guidelines we had to try something new. The existing manufactured equipment didn’t meet new requirements, so we made the decision then, if we were really going to honor the state permit specifications, we would have to build something that wouldn’t compromise our standards”.

With SouthTex BTEX-T.rex™ units in place, BTEX and aromatic removal costs are a fraction of alternative technologies and are virtually maintenance free. When reporting the state required data of BTEX emissions from amine plant vent streams, there is a confidence from operators because the BTEX-T.rex™ units exceed permit requirements with consistent and accurate readings.

With a minimum capital investment, the BTEX-T.rex™ stripping unit using the BTEX-T.rex™ engineering services will strip the BTEX components from amine, sending them with the gas to the process heater, where the components are burned safely, transformed into carbon dioxide and water vapor, economically protecting your downstream equipment, all the while in compliance with EPA regulations.

Minimum Capital Investment and Minimum Operating Expenses
The best way to compare the three options for BTEX component removal (activated carbon, vent gas incineration, BTEX-T.rex™ unit) is to compare the installation and operating costs for the same conditions. The table below illustrates economic comparisons for the three options applied to a 600 gpm amine treating plant designed for 150 MMscfd with over 600 ppmv BTEX components.
