Abstract
Current concern over the potentially negative impacts of climate change has brought attention to reduction of anthropogenic emissions of methane. Biofiltration of methane is an inexpensive technique to reduce emissions from point sources of methane arising from the production and transport of crude oil and natural gas.
Optimization of the methane biofiltration technique can be achieved through laboratory experiments and long term field studies which are costly and time consuming. On the other hand, mathematical models, verified with laboratory and field data, can be a more cost effective method for generating the necessary information to understand the processes of methane biofiltration and to design and monitor methanotrophic biofilters.
A three-dimensional mathematical model and a one-dimensional mathematical model were developed to analyze methanotrophic biofilters. Biological reactions, mass transport, heat transfer, and moisture transport were incorporated in both models. The models are capable of predicting concentration profiles of individual gases, moisture and temperature profiles, and percent oxidation of methane. Properties of porous medium and environmental data such as precipitation and ambient temperature are given as model inputs. Both models were calibrated and tested for laboratory and field conditions.
