摘要

Gas evolution rates represent an important variable to track in biological and certain electrochemical processes.Accurate gas flow rate sensors exist for gas streams possessing a pressure head,such as when pressurized air or oxygen is delivered to a fermentation process.However,these devices impose pressure heads that can inhibit gas production and,therefore,yield false measurements.Examples of effected processes would include electrochemical production of a gas at the electrode (e.g.,electrolysis) or anaerobic fermentation (e.g.,anaerobic production of methane).In this work,we present an on-line gas measurement technique that measures on-line gas production from an anaerobic microbial process that is continuously fed simulated food waste over a 6-month period.Commentary is given on the sensor's accuracy and ease of use within the context of long-term operation,ability to measure both low and high gas production rates,as well as its potential for process control and system-health monitoring.
