Methane gas processing in Akureyri

Mannvit is involved in the installation of facilities for the processing and delivery of methane from landfill gas for Nordurorka. The operation is located at the landfill site, a discontinued waste tip in Glerárdalur valley. It is estimated that the facility can produce 600.000 Nm3 of methane gas per year.

 

The project is still on-going and involves, among other things, estimating landfill gas emissions and thereby methane formation in the waste tip. A feasibility assessment for gas collection and the processing of the methane was prepared and, in addition, the options for its use in various activities were mapped out. Trial wells were drilled and the capacity of these wells was examined in order to assess the reliability of the processing forecast model. Mannvit was also involved in the selection of technical solutions and the design of the landfill gas collection system, pumping station, underground piping and sites. Mannvit, moreover, provided technical consultancy services and designs for procurement in technical solutions (i.e. scrubbing stations and dispensing stations). Furthermore, Mannvit prepared the tender documents for the earthworks and piping work and provided consultancy services as regards the permits for the operation.

“When the station begins production in mid-2014, the owners of methane fuelled vehicles can travel between Reykjavík and Akureyri on methane alone. This project will lead to a carbon footprint decrease of 11,000 tonnes of carbon dioxide per year.“
