When no natural gas pipeline is available at a site operators must flare or vent methane (GHG) and Volatile Organic Compounds (VOC). Operators rather not flare. If a pipeline is available, they profit from the sale of all natural gas produced.
Pipeline companies, however, have contractual, safety limits set at a part per million level for the oxygen they will accept into their pipeline. If the binding oxygen limit is exceeded at a production site, the site is stopped access to the pipeline, site pressures will build, and the operator must shut-in, flare, or vent. An oxygen removal system can prevent flaring and emissions.
Our Patent Application for the Exact-ORR is based on GCO LLC uniquely using proven and EPA approved every day in over-the-road vehicles and stationary engines exhaust catalytic converter technology in reverse. As a result, we do not heat the gas to remove the oxygen.
The Exact-ORR works at ambient temperatures and pressures. We enable operators to sell valuable storage tank vapors, meet mandated GHG reduction targets, eliminate costs issued by other processes requiring electric heat and/or pressure for their systems to remove oxygen from your gas.
The Exact-ORR can be profitable to operate with less that a one-year ROI to purchase. Unlike other processes that have high rental costs, require heating the gas upwards of 500 degrees (F) with the hidden costs of renting and running a 480V 3-Phase electricity generator for oxygen removal. Generators burn fuel gas and have emission issues of their own. Other oxygen removal systems create a perpetual net loss for an operator to meet reduction mandated.
Operators do not want to throw away profits, but oxygen tainted gas cannot be sold unless the oxygen is removed. Vapor Recovery Unit (VRU) systems are a proven process for capturing, pressurizing, and selling tank vapors. Storage tank vapors at an oil and gas site also have one of the highest BTU values, and operators profit from the sale of high BTU valued gas.
The majority of oxygen intrusion and GHG emissions at an site can be traced back to the storage tanks. Unfortunately, VRU systems have inherent risks of oxygen intrusion, so operators are reluctant to use VRUs.
Everyone uses an air filter at ambient temperatures on an engine to remove dirt; a catalytic converter on an exhaust to remove emissions; now operators can simply bolt-on the Exact-ORR in their piping at ambient temperatures to remove oxygen.
Operators are still allowed to flare, so when push comes to shove, it is more economical to send tank vapors down a VOC line to a flare or vent. Federal and States are mandating greenhouse gas emissions reductions.
Colorado says "To achieve the state’s 2025 and 2030 emissions goals, methane emissions from the oil and gas sector as a whole will need to be reduced by at least 33% by 2025 and over 50% by 2030. "
