Description:
In the natural gas industry, transmission pipeline operators use internal combustion (IC) gas-fired engines to provide the mechanical energy needed to drive pipeline gas compressors. As such, owners and operators of compressor stations are interested in the performance of these engines with regard to engine fuel consumption, reliability, availability, and emissions. MIRATECH Corporation has developed a technology that has the potential to improve engine performance and committed to participate in a verification of this technology. MIRATECH's GECOTIL 3001 Air/Fuel Ratio Controller (Controller) is designed to balance lean-bum engine fuel mixtures and improve fuel economy, maintenance requirements, and emissions performance.
Performance testing of the Controller was carried out at a natural gas processing station in the southern U.S. This station employs several reciprocating engines in support of its gas processing and transmission activities. The design of the Controller is applicable to two of the lean-bum engines at this facility, and these units were used for evaluation of the technology. The verification was executed in two phases of testing. Phase I evaluated Controller installation requirements and changes in fuel consumption and engine emission rates realized through use of the Controller. Phase II evaluated changes in lubrication oil degradation rates realized by using the Controller. Details on the verification test design, measurement test procedures, and Quality Assurance/Quality Control procedures for both phases of testing can be found in the test plan titled Test and Quality Assurance Plan, MIRATECH Corporation GECO(TM) 300l Air/Fuel Ratio Controller (SRI 2001a). Results of the Phase I testing are documented in a separate report titled Environmental Technology Verification Report, MIRATECH Corporation GECO(TM) 3001 Air/Fuel Ratio Controller (Manufactured by Woodward Governor Company) (SRI 200lb). Both can be downloaded from the GHG Center's Web site at (www.sri-rtp.com). This report presents results of the Phase II testing for evaluation of lubrication oil degradation rates.
