Complete Benzene, Toluene, Ethylbenzene & Xylene Elimination

Benzene is a known carcinogen and a regulated hazardous air pollutant commonly released as a by-product of glycol-based natural gas dehydration systems. As environmental regulations tighten and compliance thresholds become more stringent, operators require reliable, proven technologies to control BTEX emissions at the source.

GasPro provides industry-leading BTEX emission control systems that significantly reduce – or fully eliminate – benzene, toluene, ethylbenzene, and xylene emissions from glycol dehydrators.

Why BTEX Emissions Are a Critical Concern

Glycol dehydrators are widely used to remove water vapor from natural gas streams. During this process, small but regulated quantities of:

  • Benzene (carcinogenic)
  • Toluene
  • Ethylbenzene
  • Xylenes
  • Greenhouse Gases (GHGs)
  • Volatile Organic Compounds (VOCs)

Regulatory agencies, including the Alberta Energy Regulator (AER), require operators to reduce or eliminate these emissions to meet environmental compliance standards.

BTEX Emission Control Systems

GasPro BTEX Emission Control Options

GasPro offers multiple engineered solutions depending on emission levels and site requirements.

1. Condenser Box System

Designed to significantly reduce BTEX emissions by condensing liquid droplets from the still-column vapour stream before release.

2. Condenser + Tank Assembly

Provides enhanced liquid recovery and improved emission reduction performance compared to standalone condenser systems.

3. GasPro BTEX VRU – 100% Emission Control

For facilities requiring the complete elimination of benzene emissions, GasPro’s BTEX Vapor Recovery Unit (VRU) delivers a fully closed-loop solution.

How the GasPro BTEX VRU Works

The GasPro BTEX VRU captures emissions directly from the glycol dehydrator still column and processes them through a controlled recovery system:

  1. Vapour stream is captured before atmospheric release
  2. Vapours are cooled and condensed to collect liquid hydrocarbons
  3. Separated gas is routed into a compressor
  4. Recovered gas is returned to the system in a closed-loop configuration

This process:

  • Prevents atmospheric discharge
  • Recovers usable hydrocarbons
  • Eliminates benzene exposure risks
  • Reduces GHG and VOC emissions

AER-Approved 100% Solution

Unlike partial solutions that achieve 95% or 99% reduction, GasPro’s BTEX VRU is recognised as a 100% emission elimination solution and is approved by the AER as a compliant technological system.

Because it provides full capture:

  • No additional emission study requirements
  • No ongoing uncertainty regarding compliance thresholds
  • Simplified regulatory reporting
  • Reduced long-term compliance risk

Protect Your Facility. Ensure Compliance. Eliminate Risk.

GasPro’s 100% BTEX Emission Control Systems provide a proven, regulator-approved solution for operators who require complete benzene elimination – not partial reduction.

Contact GasPro today to evaluate your glycol dehydrator emissions and implement a fully compliant BTEX recovery solution.

Frequently Asked Questions

BTEX refers to benzene, toluene, ethylbenzene, and xylenes – hazardous air pollutants commonly associated with hydrocarbon processing.

Benzene is classified as a carcinogen and poses serious health risks even at low exposure levels. Regulatory bodies strictly limit benzene emissions.

During gas dehydration, aromatic hydrocarbons absorbed in glycol are released from the still column during regeneration.

It provides a closed-loop, AER-approved 100% capture solution, eliminating the need for further study requirements associated with partial-reduction systems.

Yes. GasPro systems can be integrated into existing glycol dehydration units with engineered customisation.

Yes. Condensed hydrocarbons are recovered, and separated gas is reintroduced into the system, improving operational efficiency.
