The only EPA Verified BTEX Removal Process
Engineered Concepts’ QLD is the only BTEX elimination process that has been tested by a third party in the field and verified by the EPA (not simulated by an EPA approved computer program). Engineered Concepts’ Quantum Leap Natural Gas Dehydration process captures all still column emissions and routes them to the fuel system or sends them to the sales line. Unlike common BTEX units which rely on ambient cooling to condense the still column overhead products, Engineered Concepts’ QLD precisely controls the condenser temperature to provide consistent and reliable operations regardless of the weather or season. Because the QLD is an entirely different closed (odorless) process, comparison to a common BTEX unit system is literally like comparing summer to winter. All common BTEX units vent uncondensed vapors as evident by the odors on the location. As is commonly known, cold ambient conditions can cause condenser freezes that compound the venting from the common BTEX unit. In contrast, the closed QLD process ensures that virtually all BTEX, methane and VOCs are condensed or used as fuel regardless of the ambient temperature.

Engineered Concepts QLD glycol dehydration and VRSA operate in unison to recover all BTEX and flash vapors and tank vapors. Recovered vapors are used as fuel or go to sales. No flaring! No venting! No emissions! |
A dehydrator incorporating QLD is obviously more expensive than a standard dehydration unit. However, additional income from the recovered emissions can quickly pay for the additional capital outlay. The greater the gas production and the richer the gas, the faster the QLD pays out and becomes a revenue generator. |

This QLD in Colorado processes about 26 MMscfd of rich natural gas. Overall savings attributed to the QLD process is estimated at $138,000 per year @ 4.00 gas prices. Stringent EPA field testing verified the HAP destruction efficiency at greater than 99.74% (+/- 0.01%).
For this particular application, the four main sources of cost savings for the QLD process were:
- Either replace the Kimray pump with electric or modify pump operation or collect emissions and send vapors to VRU.
- Eliminating gas stripping
- Using still column overhead emissions as fuel for the system.
- Lowering thermal oxidizer fuel use.
Total previously wasted gas in the pumps, gas stripping, still column overheads and thermal oxidizer was calculated to be 4.16 MMbtu/hr.
The QLD process can be tailored to meet your particular dehydration requirements and may not include all the equipment or savings noted above.
