Gaspro Compression Corp. has been developing dependable, low maintenance and user-friendly compressor packages that surpass industry standards since 2004. All our packages are engineered for extended, cost-efficient operation and we’re continually improving and innovating our products to keep up with the ever-changing industry demands. Gaspro offers various BTEX emission control systems that can significantly reduce or completely eliminate BTEX emissions. 

What is BTEX?

BTEX refers to the chemicals benzene, toluene, ethylbenzene and xylene. These compounds occur naturally in crude oil and can be found in seawater in the vicinity of natural gas and petroleum deposits. Other natural sources of BTEX compounds include gas emissions from volcanoes and forest fires. The primary man-made releases of BTEX compounds are through emissions from motor vehicles, aircraft and cigarette smoke. BTEX compounds are created and used during the processing of petroleum products and during the production of consumer goods such as paints and lacquers, thinners, rubber products, adhesives, inks, cosmetics and pharmaceutical products. These compounds are among the most abundantly produced chemicals in the world. BTEX are in a class of chemicals known as Volatile Organic Compounds (VOCs) and are toxic to humans. Their capture and/or removal from polluted environments is crucial.

What is a BTEX condenser unit? 

A BTEX condenser unit is an accessory of a natural gas dehydration unit. Producers use these units to condense four harmful vapours (benzene, toluene, ethylbenzene and xylene) into liquid and dispose of them. BTEX condenser units are used for safety, environmental and regulatory reasons.

Where are BTEX condenser units used?

Gaspros’ BTEX condenser units are used in a variety of applications:

  • Glycol dehydration towers
  • Vapour recovery from storage tanks
  • Hydrocarbon recovery


Why are BTEX condenser units needed?

Benzene emissions from glycol dehydration units are regulated in Western Canada. Alberta has initiated a methane emission reduction plan for the oil and gas sector. The major challenge in reducing emissions from dehydration systems is designing systems to capture the gas from the flash tank vent and still column (glycol regenerator) overheads. The still column operates at atmospheric conditions and the vented gas is wet; this leads to additional effort to design a system to handle wet vapour at low pressures. GasPro Compression Corp. has developed a vapour recovery unit to reduce/eliminate BTEX emissions from glycol dehydration plants. The potential BTEX and GHG (greenhouse gas) emissions reduction using the GasPro BTEX VRU is 100%. The recovered gas is compressed and recycled as fuel versus being vented to the atmosphere or simply burned in a flare or incinerator. GasPro’s technology is simple to understand, reliable, robust and requires virtually no operator intervention.

How does a Gaspro BTEX condenser unit work?

Our BTEX VRUs capture emissions from the still-column of the glycol dehydrator, condense it to collect all the liquid droplets and pass the separated gas into the compressor. Gaspro BTEX VRU applies a closed-loop system and is an approved technological solution by the AER (Alberta Energy Regulator) as a 100% solution to the problem, thus eliminating the need for further study requirements as is required by other 95% or 99% solutions. Gaspro’s BTEX emission control systems are environmentally responsible, self-contained and quick and easy to install. 

The features of a Gaspro BTEX condenser unit:

  • Condenses glycol regenerator overheads
  • Streams in Natural gas dehydration facilities
  • Environmentally responsible
  • Quick and easy installation
  • Self-contained
  • Built-in temperature control to eliminate freezing in winter
  • Standard storage tank can be used to contain liquids, minimizing capital costs
  • Recovered gases can be used as clean, moisture-free fuel gas


Gaspro’s BTEX emission control systems are a simple and economical solution to reduce BTEX emissions from glycol regenerators on natural gas dehydration facilities. All our packages are available to purchase, rent-to-purchase and rent; whichever best suits the client. Our team of qualified service technicians ensure that the units operate at optimum conditions and last longer.
