Gas & Vapor Recovery Systems

Emissions Reduction Equipment



Since 1980, Jordan Technologies / AEREON has designed, engineered, supplied and serviced Activated Carbon Vapor Recovery Units (VRU). 

Our units recover hydrocarbons (VOCs) in a variety of applications such as truck, rail, marine & tank breathing applications and in a variety of products like gasoline, naphtha, crude oil, BTEX aromatics meeting the most stringent emission requirements. 

Process technology is based on adsorption of the VOC stream onto activated carbon, vacuum regeneration of the carbon and absorption of desorbed VOC in the liquid phase in an absorber column with liquid absorbent circulation. This process has been recognized by several Environmental Authorities as BDT (Best Demonstrated Technology) to recover VOC from fuel loading applications.  A user-friendly PLC control package and SCADA are designed to limit your down time and store all the process data for easy troubleshooting. 

The AEREON / Jordan Technologies Activated Carbon VRU recovers greater than 99% of VOCs generated during product loading providing an attractive pay back on capital investment. Recovery rates for gasoline

Marine Vapour Recovery Unit

In order to comply with all of the United States Coast Guards’ (USCG) rules and regulations as well as international standards (IMO), a vast knowledge and experience of marine loading applications is required to safely design a carbon based Vapor Recovery System.

With a vast experience in the design and supply of Marine Vapor Recovery Units (MVRU) worldwide; AEREON has the complete knowledge of what is required in these systems to allow quick approval by the USCG or to design a Marine Vapor Control System to the most stringent Safety standards.

Dock Safety Units (DSU)

Our DSUs comply with the U.S. Coast Guard regulations as well as international standards which define the level of safety equipment allowed to be installed in marine vapor control solutions.

AEREON has over a decade of experience in the design, engineering and supply of Gas Recovery Systems for different applications. A gas recovery package is comprised of a compression system and auxiliary components which allow reliable and safe operation over the entire design range. Our units are applied in well-head compression, crude oil stabilization and flare gas recovery.

Well-Head Compression

The AEREON natural gas Wellhead Compression Unit is a durable, rugged and reliable solution for depleted or low pressure natural gas wells. The wellhead compressor can also be used in places where line boosting is necessary or can be used to simply increase production. Using AEREON experience coupled with field feedback has helped this product evolve into what is considered one of the most preferred gas compressor technologies.

Mechanical Vapor Recovery Units

Our Mechanical Vapor Recovery Unit (MeVRU) is a pre-engineered, customizable package that is ideal for nonattainment areas where air quality regulations require vapor recovery. It consists of a direct driven compressor, oil coolers, and a precision operating system, which is able to operate continuously and with very little personnel interaction. The unit can be outfitted with a rotary screw; piston or rotary vane compressor powered with either an electric or EPA-certified natural gas engine. AEREON’s standard MeVRU’s come in sizes ranging from 20 – 600 m3/h till 14 barg.

A Flare Gas Recovery System (FGRS) is a System designed to reduce plant/site continuous flaring and recover valuable flare gas to reuse it as fuel or feedstock. A FGRS provides the benefit of conservation of resources and reduction of emissions by recovering process vent gases, often with considerable heating value, instead of flaring. In a FGRS, Flare gas is withdrawn upstream of the Liquid Seal, compressed through a positive displacement compressor, discharged into the Separator, then routed back to the plant. The Liquid Seal maintains a positive pressure on the flare header to prevent air ingress. If flare gas stream exceeds FGRS capacity, gas will flow to the flare. If flare gas stream is less, then FGRS will turn down by staging compressors and/or recycle it.
