Abstract

The opportunity for heat recovery and greenhouse gas elimination from dilute methane emissions from coal mine ventilation air, oil and gas industries and landfill by using a Catalytic Flow Reversal Reactor (CFRR) technology is discussed. The CFRR technology has been experimentally proven to eliminate methane as dilute as 0.1 \% v/v in air, with no requirement for external heat. Indeed, for concentrations above 0.3 \%v/v, the methane heat of oxidation can be recovered with efficiency up to 90\% as 800oC hot air. Utilization of this heat further reduces greenhouse gas emissions by correspondingly decreasing world fuel energy consumption. This paper describes the operating principles of CFRR technology, mathematical simulations and experimental work performed on 500 mm pilot units, for estimating the heat extraction efficiency from dilute (0.1-1.0 \% v/v) methane in air gases. A preliminary economic analysis of an industrial CFRR application is presented.
