- W2094266427 abstract "Abstract With the advent of replacement energy cost pricing for natural gas, the recovery and treatment of methane generated by sanitary landfills has become a commercial reality. The first landfill methane recovery plant, owned and operated by Getty Synthetic plant, owned and operated by Getty Synthetic Fuels, Inc., has been in operation at Palos Verdes, California since 1975. Getty has built a second plant, which has been in operation in the city of Monterey Park, California since August 15, 1979. These two facilities are the only plants in the United States which produce pipeline quality gas from landfills. Although similar to the Palos Verdes facility in some respects, the Monterey Park methane recovery facility is four times as large, and represents a significant advance in the State of the Art of landfill methane recovery and purification. This paper will discuss the similarities between these two operations, but, more importantly, will point out the significant technological advances made over the past four years, which have advanced landfill methane recovery from the demonstration project phase to the large scale, economically viable operation that it is today. Background Historically, the generation of methane from the natural decomposition of refuse in sanitary landfills has long been known, but was considered for years to be more of a liability than an asset because of its potential for underground migration into potential for underground migration into nearby areas. Many landfills have controlled this migration by the use of venting systems or peripheral wells from which the gas was withdrawn under vacuum and pumped to flares. Although the energy value of this gas began to be realized in the early 1970's, there was not sufficient economic incentive to develop it on a commercial scale. The very creation of the natural gas industry itself, and the explosive growth in the transmission and consumption of natural gas was brought about, in part, by an extremely low pricing structure. This continued, artificially set, low gas price discouraged the development of alternative energy sources for a number of years. With the natural gas shortage of 1973, and the rapid increases in the price of natural gas which followed, the possibility of developing landfill methane possibility of developing landfill methane recovery on a commercially viable scale began to come into focus. The world's first landfill methane recovery facility at Palos Verdes, California, was built entirely with private capital by Reserve Synthetic Fuels, the predecessor of Getty Synthetic Fuels, Inc, and began operations in June, 1975. This was a pilot plant, designed primarily to prove the technical plant, designed primarily to prove the technical feasibility of methane recovery and processing on a commercial scale. Since low pressure and volumes would be encountered, a molecular sieve, pressure swing adsorption system was used for carbon dioxide removal, with activated carbon pretreaters to remove other components of the gas stream. Severe technical difficulties were encountered during the first year of plant operation, requiring over $1,000,000 in major plant modifications to correct. Since returning to operation in January, 1977, the Palos Verdes facility has enjoyed a 90%-plus on-stream time for the past three years. The lessons learned in the development of this pilot facility proved invaluable in the design of a second, larger facility at the Operating Industries landfill in Monterey Park, California.
