The QLD process consumes or sells all Uncondensed Hydrocarbons
The still column overhead vapors (steam, methane, ethane,Vocs and HAPs) are collected and condensed. The condensing temperature is thermostatically controlled to assure efficient condensation in all weather conditions. Condensed hydrocarbons from the still column vapors form a stable product and are routed to oil storage after separation from the condensed water. All uncondensed hydrocarbons are routed to the fuel system and consumed by the burner of the glycol reboiler or collected by the VRU for sales.

QLD emission free technology retrofits into existing systems of
any capacity without variance in efficiency or functionality.

QLD Process Eliminates Previous BTEX Eliminator Shortcomings
QLD handles problems that other BTEX elimination processes do not address - for example,
the large volume of emissions attributed to the Kimray pumps. Other BTEX elimination systems derive their claims using computer programs rather than “real world” gas streams that often contain more BTEX and Vocs than the limiting constraints of their software.

These still column overhead vapor elimination technologies include flares and thermal oxidizers (incinerators). Flares and thermal oxidizers require substantial quantities of supplemental fuel gas to operate. Since the still column vapors are “free-floated” to the flare or combustion chamber of the thermal oxidizer at essentially atmospheric pressure, improper mixing of these vapors with oxygen results in incomplete destruction of these polluting and explosive vapors. All hydrocarbons - both non-condensable vapors and condensable liquids -that are ineffectively destroyed in this manner are unnecessarily wasted, providing no return to the operator.

In contrast, non-condensable hydrocarbons fuel the QLD reboiler. The hydrocarbons are compressed and are directed to the reboiler combustion chamber without bypassing any of the fuel safety devices, shutdowns, flame arrestor or operator interface devices. In the reboiler combustion chamber, an improved burner system burns the hydrocarbons at an efficient fuel-air ratio. EPA tests verified the QLD’s improved burner system surpassed all EPA threshold limits for NOx, CO2 and unburned hydrocarbons. In fact, unburned HAPs and methane levels were below the detection level of the EPA test instruments.

QLD Uses a Fraction of the Fuel Required for a Flare or Oxidizer
The QLD process provides the majority of the reboiler fuel. If a flare or thermal oxidizer is used to destroy the still column vapors, the entire quantity of required fuel must still be supplied to the reboiler and supplemental fuel must also be supplied to the flare or thermal oxidizer. The fuel consumed by QLD is a fraction of the fuel required for a flare or thermal oxidizer equipped dehydrator, and as a result, the combustion emissions are a fraction of those systems using a flare or thermal oxidizer.

A Thermostatically Controlled “All Weather” Process
Ambient temperature dependent BTEX designs rely on natural draft air coolers to condense still column vapors. operators are left at the mercy of the weather without control of the process. Without control of the process, cold weather can result in venting or flaring of all the still column vapors. In contrast, the QLD process is continuously thermostatically controlled.

Other BTEX elimination designs “free float” the vapors at atmospheric pressure into the reboiler combustion chamber or stack and rely on the stack draft to pull and properly mix the vapors with oxygen. This approach increases the risk of fire or explosion and vents unburned hydrocarbon vapors directly to the atmosphere. The QLD process provides operators complete control of all the captured emissions.

Eliminates Kimray pump Gas Emissions
Pressures as low as 50 psig are no longer impossible operating conditions with the QLD. The QLD process eliminates Kimray pump gas emissions and the low-end pressure barrier created by Kimray pumps in traditional dehydration processes. QLD is flexible and operates over a wide range of conditions.

Your Bottom line is the Bottom Line
With tight regulations, fines and even shut downs due to the detection of BTEX, the QLD provides operators the means to responsibly eliminate dangerous emissions from the dehydration process. Although the capital outlay for QLD may be higher, the QLD pays for itself. The greater the volume - the richer the gas -the faster the payback. Once the QLD pays for itself, it then becomes a consistent and reliable revenue generator for years to come.
