The BTEX Buster®, BTEX eliminator and other BTEX units that route VOCs and HAPs to the burner and the exhaust stack often experience limited effectiveness when dealing with high gas volumes, rich gas and in areas which experience cold temperatures and wide temperature swings.  Initial 99.7% BTEX destruction claims were based upon a basic modeling program under ideal “computer” conditions. None of the BTEX Buster type elimination systems have ever been verified through EPA field-testing except Engineered Concepts EFD (Emission Free Dehydration) system. EPA field-testing verified the EFD BTEX eliminator process actually captured 99.74% of the VOC emissions and used them for sales or fuel. An EFD BTEX removal unit is a closed, highly efficient mechanical system and does not produce chemical bi-products such as brine that require a controlled disposal.

The patented Emission Free Dehydration Technology
(EFD) is the only EPA verifed process that captures virtually all hydrocarbon emissions. The EFD pays for itself by using the captured emissions as valuable fuel products. This technology eliminates odors and creates a safer working environment while reducing fuel requirements and maintenance on any new or retrofit dehydration application.

Stringent EPA Field Testing
The U.S. Environmental Protection Agency verified in stringent field-testing (not computer simulation) that the EFD captures essentially 100% of all HAPs (Hazardous Air pollutants) comprised primarily of Benzene, Toluene, Ethylbenzene and Xylenes (BTEX) plus n-Hexane.

The EPA field test further concluded the process effectively eliminates all Volatile organic compounds (VOCs) and methane emissions associated with the glycol dehydration process.

Retrofits into Existing Systems of All Capacities
EFD may be incorporated into new or retrofitted to existing systems of any capacity without variance in efficiency or functionality. Retrofitting to an existing dehydrator usually requires minimal field construction. EFD applies to small remote wellhead applications, large plant dehydrators, or offshore service—anywhere elimination of hydrocarbon emissions, increased dehydrator performance, and improved safety is desired. The EFD system may be used independently to capture still column vapors or may be installed in conjunction with a VRU to capture all the vapors from the entire location.



Stringent EPA field testing (not computer modeling) verified the EFD process captures virtually 100% of all BTEX and other hydrocarbons.

First in Safety
Unlike other BTEX systems that depend upon ambient cooling, the EFD is a temperature controlled “all-weather” system. By design the EFD is not subject to freezing which results in venting of the emissions. The EFD process is safer because it captures virtually all toxic and explosive vapor emissions. These vapors are either condensed to stable liquids or compressed and used as fuel in the EFD process. Compression and absolute control of the non-condensable vapors by the EFD process is a key environmental and safety feature. The risk of fire or explosion due to the combustion of “free floated," uncontrolled hydrocarbon vapors into the combustion chamber or stack is eliminated.
