method for recovering methane from a reactor liquid effluent, and reactor system for preparing biogas by anaerobic degradation of one or more organic substances

摘要

The invention relates to a method for recovering methane from a liquid effluent of a reactor wherein a waste stream comprising one or more organic substances has been subjected to an anaerobic degradation process in which reactor biogas, comprising methane, has been produced from said one or more organic substances, the liquid effluent comprising dissolved methane, the method comprising transferring dissolved methane from the effluent to a gas phase and using the methane to produce energy.
