Predicting Wobbe Index and methane number of a renewable natural gas by the measurement of simple physical properties

摘要: Abstract This study describes a fuel quality prediction strategy that predicts the parameter and component composition of Renewable Natural Gas (RNG) containing CH4, C2H6 CO2. Onsite measurement gas properties in renewable natural is necessary to ensure an expected level quality, which must be maintained for better combustion efficiency. The Wobbe Index (WI) methane number (MN) are indicators used. To predict WI, MN, composition, data set consists thermal conductivity sound velocity gaseous mixture as function its temperature, pressure was created. Through regression analysis set, model estimates MN from physical (temperature, pressure, velocity), developed. results including can accurately estimate presented this paper.
