The document describes how automated air/fuel ratio (AFR) controls can optimize the operation of natural gas engines to reduce fuel consumption and emissions. It highlights a case study where the installation of the REMVue system on 51 engines in the Gulf of Mexico led to fuel savings of 18-24% and a reduction of 128 Mcf of methane emissions per unit annually. The economic analysis indicates a total cost of $6.1 million for the project, with an average installation cost of $120,000 per unit and a calculated payback period of 1.4 years based on fuel savings.

• The REMVue automated AFR control system, marketed by REM Technology Inc., utilizes electronic control, high-energy long-duration sparks, and mechanical modifications to correct engine imbalances, resulting in fuel savings of 18 to 24 percent.
• In a deployment across 51 engines in the Gulf of Mexico, the technology achieved an average reduction of 128 Mcf of methane emissions per unit per year according to AP-42 emission factors, though vendor factors for similar conditions suggest a higher reduction of 758 Mcf.
• The economic analysis of the 51-engine installation shows a total cost of $6.1 million, with average capital costs of $120,000 per unit and a payback period of 1.4 years based on fuel savings valued at $3 per Mcf.
• A 2004 audit of 20 percent of the installed base showed annual reductions of 3,549 tons of unburned hydrocarbons, 2,309 tons of CO2, and 83,300 tons of CO, while engine availability increased by 2.25 percent.
