THE GAS RECOVERY SYSTEM Emerging Green Technology ISOBUTANE BARGE THE GRS: CLEANING DEMONSTRATION The Gas Recovery System Capabilities A SUCCESS The GRS recovery system was designed as a multi-purpose and transportable unit for mobile or onsite applications. The KIRBY INLAND MARINE, Channelview, TX. unit recovers vapors and liquids through its highly economical and environmentally friendly process, rather than current Last minute cleaning change from a butadiene to product destruction using a flare or incinerator. The system is isobutane barge was no problem for the GRS. truly unique and its flexibility allows recovery of multiple Adjustments were made and the GRS’s versatility was products at several types of facilities. challenged and demonstrated…successfully. Economical Benefits The GRS patented vapor recovery technology offers a clean The Gas Recovery System and energy efficient method for transport facilities and terminals to unload and clean cargo container vessels and pressure tank vehicles more efficiently. Facilities & operations looking to Environmental Benefits implement the GRS The GRS process eliminates flaring or incineration when •Port & Marine Transport Terminals products are reclaimed and recycled to temporary or permanent storage. The unit also reduces emissions when •Chemical Storage Facilities products are purged, recovered, and destroyed at better •Rail Tank Car Terminals manageable and acceptable rates during cargo cleaning operations. The GRS unit’s minimal sub-PPB or low-PPM •Transloading Terminals 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 non- attainment 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 The GRS Benefits or eliminating flaring and incineration with the GRS will lower emissions, lessen environmental scrutiny, and provide a solution for meeting these costly mandated regulations. Environmentally Safe No Secondary Pollution In addition, the GRS unit is additionally environmentally safe Emissions below industry regulations because no secondary pollution such as acid gases, CO2 Reduces Flaring & Emissions emission, waste-water, nitrogen oxides, dioxins, and other Highest VOC & HRVOC removal efficiency pollutants are created. Adjustable flow & concentration Recovers directly to a flare or storage Products recovered uncontaminated Products recovered on-grade specifications Smallest Equipment Foot-print Proven Reliability Low operating & maintenance costs The 2002 Vopak 6650 CBM VCM Sphere Decontamination Low energy consumption Project in Teeside, Australia resulted in only a small Intrinsically Safe product loss of 2 kilograms, generated 4660 grams in Mobile & Transportable 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 The Gas Recovery System compound characteristics being liquefied. System Process: Liquid nitrogen is then introduced to a nitrogen GRS Gases & Chemical Applications 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 Purging liquefied by heat exchange with the chilled heat Recovery transfer fluid. From the condenser, the liquefied Re-liquefaction product incondensable mixture flows to the vapor & Reclamation liquid separator. Incondensibles, such as nitrogen Cleaning - RCRA Rules vapors, are released from the separator into the Decontamination atmosphere. The condensate is pumped from the Degassing separator liquid collector to storage or to a plant Inspection - Ka-Kb EPA Rules facility. Complete condensation occurs in the condenser and an extremely efficient product Gassing-up recovery is achieved. Cooling-off Pressure Release Recovery The GRS includes a fully integrated control system that provides capabilities to easily adjust flow and concentration rates. The unit has minimal moving Recovery Principles parts, requires minor annual maintenance, and performs with annual low operating costs. The GRS technology increases degassing operations with capabilities to move from product Nitrogen To to product with a simple purging of the system. Atmosphere Purge & Recovery Stage Option 2 The GRS versatility serves as a new method for Recovered Product loading, unloading and transfer of multiple Option 1 To Flare products from various pressure vehicles.
