Gas Recovery System Now Recovers at Double the Capacity
Purges Recovers
The GRS offers its patented cryogenic technology to the Rail industry. This new emerging technology and its recovery, reclamation, and cleaning capabilities will surpass the current, out dated or single commodity abatement systems especially the cost-intensive steam cleaning process. The GRS multiple products versatile handling capabilities will upgrade rail tank car cleaning facilities to a new efficiency level. The GRS process recovers and reclaims (VOC) Volatile Organic Compounds gases/vapors and liquid heels while cleaning and reclaiming multiple products. The system’s efficient recovery rate compared to current purging, flaring, and incineration processes, also streamlines tank car cleaning and turnaround, while minimizing offline or downtime losses. The Gas Recovery System is seeking to benchmark a new Green standard for (HRVOC) Highly Reactive VOC recovery, and reclamation applications in several markets including marine transport, bulk storage spheres, and rail cleaning facilities. The GRS unit ownership will give tank car cleaning facilities the competitive operations edge to focus on core business of leasing and manufacturing rail tank cars fleets.
Reclaims Unloads
The GRS reclamation capability provides product shippers new revenue streams such as commodity buy-back programs from reclaimed tank car heels. The system’s efficient recovery process will reclaim products at on-grade specifications.
Cleans “Through superior design and foresight, the GRS engineers double the capacity of recovery and vapor flow rates, while the unit maintains the current dimensions and foot-print.”
“The GRS is the only cryogenic, compact, mobile, and efficiently designed system that truly provides purging, recovery, reclamation, and cleaning directly to a flare or storage simultaneously in a one step process.”

“The GRS minimal emissions are limited to sub-PPB or low-PPM levels during recovery operations.”
The GRS system unit was tested and certified at Norway’s SINTEF Energy Research & Refrigeration Labs. For more information on SINTEF, visit www.sintef.no
Our focus is to establish the GRS as industry’s best available technology and a standard in cargo containment abatement. Our mission is to offer this new emerging technology to facilities striving to reduce VOC flaring or incineration emissions. Vapor & Liquid Heel Recovery To Tank Car Temporary Storage Configuration

THE GRS:
The Gas Recovery System Capabilities The GRS recovery system was designed as a multi-purpose and transportable unit for mobile or onsite applications. The unit recovers vapors and liquids through its highly economical and environmentally friendly process, rather than current product destruction using a flare or incinerator. The system is truly unique and its flexibility allows recovery of multiple products at several types of facilities. Economical Benefits The GRS patented vapor recovery technology offers a clean and energy efficient method for transport facilities and terminals to unload and clean cargo container vessels and pressure tank vehicles more efficiently. Environmental Benefits The GRS process eliminates flaring or incineration when products are reclaimed and recycled to temporary or permanent storage. The unit also reduces emissions when products are purged, recovered, and destroyed at better manageable and acceptable rates during cargo cleaning operations. The GRS unit’s minimal sub-PPB or low-PPM emission rates are centrally regulated by the units control system. The Texas Commission on Environmental Quality (TCEQ) has newly imposed the Highly Reactive Volatile Organic Compounds (HR-VOC) Chapter 115 mandate for nonattainment areas, which will vigorously begin to regulate emissions of targeted compounds such as Ethylene, Propylene, 1,3 Butadiene, and Butenes. The GRS together with existing flares, incinerators, and recently implemented on-line emissions measurement devices, is a system strategy will begin help meet local, state, and federally mandated ozone attainment and emission’s cap compliance. Reducing or eliminating flaring and incineration with the GRS will lower emissions, lessen environmental scrutiny, and provide a solution for meeting these costly mandated regulations. In addition, the GRS unit is additionally environmentally safe because no secondary pollution such as acid gases, CO2 emission, waste-water, nitrogen oxides, dioxins, and other pollutants are created.
The 2002 Vopak 6650 CBM VCM Sphere Decontamination Project in Teeside, Australia resulted in only a small product loss of 2 kilograms, generated 4660 grams in emissions, and was completed in 6 days.
THE GAS RECOVERY SYSTEM Emerging Green Technology THE GRS:
The GRS Technology System Summary: The GRS utilizes liquid nitrogen as the system’s coolant. The cargo vapors are simply replaced by nitrogen vapors generated during the liquefaction process. The nitrogen is also used to re-liquefy the cargo vapors, which are then pumped into the unit for complete product and nitrogen separation. The product is then recovered and reclaimed directly to a flare or storage and the nitrogen is released to the atmosphere through the unit’s vent stack as pure nitrogen. System Feature: A direct heat exchange between the liquid nitrogen and the cargo vapors would result in operational problems in most cases, due to solidification of most hydrocarbons at extreme low temperatures. To avoid this problem, a heat transfer fluid is used as the intermediate between both the liquid nitrogen and cargo vapors. The temperature of the heat transfer fluid is adjustable based on the compound characteristics being liquefied.
The Gas Recovery System
System Process: Liquid nitrogen is then introduced to a nitrogen vaporizer. There it is vaporized against the heat transfer fluid with the result of cooling down the latter. In the cargo condenser, the product is liquefied by heat exchange with the chilled heat transfer fluid. From the condenser, the liquefied product incondensable mixture flows to the vapor & liquid separator. Incondensibles, such as nitrogen vapors, are released from the separator into the atmosphere. The condensate is pumped from the separator liquid collector to storage or to a plant facility. Complete condensation occurs in the condenser and an extremely efficient product recovery is achieved.

GRS – Gas Recovery System
VRU – Vapor Recovery System
VPS – Vapor Purging System
A Vapor Recovery Unit (VRU) traditionally only purges vapors for direct flaring. A Vapor Purging Unit (VPU) traditionally functions only by introducing pressure or blowers into cargo containers which forces vapors to a permanent or mobile flare. The Gas Recovery System (GRS) provides degassing, de-heeling, cleaning and includes recovery and reclamation of liquid and vapor heels simultaneously. Products are reclaimed on-grade specification ready for reuse, market resale, or return to the original customer or manufacturer.
Today the GRS is the only true recovery and reclamation system that is a patented technology, multiple compounds friendly, has wide-ranging use, efficient process, a green solution, and provides best available technology.
