Reliability Assessment of Landfill Gas Collection System

Abstract

The paper conducts a reliability analysis based on the technical scheme of a simple installation of a landfill gas collection system. This kind of installation should be considered as an object of multi criteria problem, because of that, the calculation was carried taking into account economical aspect as well as environmental one, on reliability schemes prepared for each aspect. Based on obtained results, authors made changes in technical structure of the installation which allowed to eliminate its weakest elements which caused lower values of reliability indexes. After recalculations it was possible to compare obtained results and asses, if proposed changes in the structure of this installation, will cause expected improvement of reliability level of the entire system.
