EFD

Although BTEX is a major concern as a gas dehydration hazardous waste, there are other hazardous
wastes, methane gas, and hydrocarbon components produced by the dehydration process. Most methane
emissions produced by gas dehydration are by Kimray® glycol pumps, gas stripping of the rich glycol,
and flashing as the rich glycol is released from high pressure to atmospheric pressure. Conventional
dehydrator still columns, without equipment to recover or destroy the overhead hydrocarbon emissions,
emit the overhead hydrocarbon emissions directly to the atmosphere.

CH4 (Methane) is 21 times more destructive as a greenhouse gas than CO2 (Carbon Dioxide).

Dehydration is the third largest CH4 (Methane) emission source in the natural gas production industry.

Glycol dehydrator venting produces over 80% of the oil and gas industry’s annual HAP and VOC
emissions.

To address a range of field conditions, Engineered Concepts has 3 varieties of Emission Free Dehydrators
(EFD) and Emission Free Systems (EFS) that, regardless of size, all produce the same results of a 99.74%+/-
HAP (hazardous air pollutants) and VOC (volatile organic compounds) destruction or recovery efficiency.
All of the systems can be operated with or without electricity and generate profit to the operator
throughout the life of the dehydrator.

Retrofitting a dehydrator already in the field requires only minor changes to the dehydrator

A. With Electricity – This system uses an emissions free electric glycol pump, an effluent condenser, eductor, and low-pressure (approximately 4 ounces) liquids removal separator. The electric glycol pump is used to circulate the process glycol. The condenser receives the effluent from the reboiler still column vent. The hydrocarbons and water v***r from the still column are routed through the condenser to the liquids removal separator operating at ounces. Liquids condensed from the still column effluent are sent to storage or disposal. The noncondensable hydrocarbon v***rs are sent to the eductor system. The eductor system captures and compresses the non-condensable v***rs before sending them back to the dehydrator fuel system. The v***rs to the reboiler are compressed to primary fuel gas delivery pressure. By capturing the non-condensable v***rs and sending them back to the fuel gas system, the EFD supplies an estimated 80% of the dehydrator's total fuel gas requirements and, because the emissions are pressurized, they burn efficiently and safely. By supplementing the fuel required to fire the reboiler burner, this system significantly reduces the cost of operating a dehydrator.

The patented Quantum Leap Natural Gas
Dehydration Technology
(QLD) is the only EPA verified process that captures
virtually all hydrocarbon emissions. The QLD 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.

Recovery of all still column overhead v***rs.
The EFD systems can recover all the hydrocarbon emissions created by the dehydration of natural gas including stripping gas. Under normal operation, no emissions, from the dehydration process, are vented or routed to the stack, flare, or thermal oxidizer. 100% of the hydrocarbons are utilized. Hydrocarbon recovery depends on the composition of the inlet gas stream. For most applications the recovery ranges from 1000 to 2100 BTUs of fuel gas plus 0.005 to 0.012 gallons of condensate per gallon of glycol circulated. Therefore, for a dehydrator circulating 1 gpm of glycol, the recovery would be valued in the range of $6,000 to $17,500 per year depending upon the current natural gas prices.

Slug Containment

The Treater-Combo is ideal for gas wells producing by artificial lift. Artificial lift wells produce a slug of liquid with the gas every time the piston operates. The Treater–Combo is designed to separate the gas from the liquids and catch the slug in the HP Separator. The liquids collected are routed to the Free Water Knock Out section and then the Treater for further processing. The HP Separator can be designed to catch any reasonable sized slug, but usually on the order of 5 to 7 barrels.

Slug Containment, Separation, Free Water Knockout and Treating All In One

The Engineered Concepts Treater-Combo can combine all of the functions of a Slug Container, High-Pressure Separator, Free Water Knock Out, Treater, Heater and Fuel Supply on a single skid. These production packages arrive complete, ready to commission - eliminating logistics hassles, delay and costly on-site installations. Combination packages can be designed and packaged to meet any field requirement including combo packages strictly for oil/gas separations. These combination packages can be duplicated so that their operation is consistent unit to unit. Most Treater-Combo designs are a result of Engineered Concepts working with your engineering and field personnel to develop your product. Your production requirements and operating preferences are worked into the final design to satisfy your production needs.

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

Engineered Concepts exclusive PICT technology makes v***r recovery operations reliable and profitable…Finally!
The PICT-V process utilizes unique temperature controlled valves that control recycles caused by the overcooling of the compressed gases (condensation) during cold weather operation in geographic regions that do not experience harsh extended cold weather.
The PICT-L is a self contained closed system that circulates coolant much like an engine cooling system to control interstage temperatures. The PICT-L can be used in all weather conditions.
During cold weather, the PICT-V and L maintain the optimum interstage temperature to keep recycles in check. With interstage temperatures controlled, a PICT equipped compressor is unaffected by cold weather.
