Essential Interview Questions For Methane Gas Generation System Technician
1. Explain the different types of methane gas generation systems and their applications.
- Anaerobic digesters: These systems use bacteria to break down organic matter in the absence of oxygen, producing methane gas as a byproduct.
- Landfills: Landfills are designed to decompose organic waste, producing methane gas in the process.
- Wastewater treatment plants: Wastewater treatment plants use anaerobic digesters to break down organic matter in wastewater, producing methane gas.
2. Describe the components of a typical methane gas generation system and their functions.
Components of Anaerobic Digester:
- Feedstock: Organic matter that is broken down to produce methane gas.
- Digester: A closed vessel where the feedstock is broken down by bacteria.
- Gas holder: A storage tank for the methane gas produced.
- Effluent: The digested material that is left over after the methane gas has been produced.
Components of a Landfill Gas Collection System:
- Landfill: A site where waste is deposited and decomposes.
- Gas collection wells: Vertical pipes that are installed in the landfill to collect methane gas.
- Gas collection header: A pipe that collects methane gas from the wells.
- Blower: A device that moves methane gas through the header.
- Flare: A device that burns methane gas to prevent it from escaping into the atmosphere.
3. Explain the factors that affect the efficiency of a methane gas generation system.
- Feedstock quality: The type and composition of the organic matter used as feedstock can affect the rate of methane production.
- Temperature: The temperature of the digester affects the activity of the bacteria that break down the feedstock.
- pH: The pH level of the digester affects the activity of the bacteria that break down the feedstock.
- Mixing: The mixing of the feedstock in the digester helps to ensure that the bacteria have access to the organic matter.
- Retention time: The length of time that the feedstock is retained in the digester affects the amount of methane gas that is produced.
4. Describe the safety hazards associated with methane gas generation systems and the measures that can be taken to mitigate these hazards.
- Fire and explosion: Methane gas is highly flammable and can easily ignite, posing a fire and explosion hazard.
- Asphyxiation: Methane gas can displace oxygen in the air, posing an asphyxiation hazard.

- Waste reduction: Methane gas generation systems can help to reduce the amount of waste that is sent to landfills.
- Improved air quality: Methane gas generation systems can help to improve air quality by reducing the amount of methane gas that is released into the atmosphere.
6. Describe the different methods for monitoring the performance of a methane gas generation system.
- Gas flow rate: The flow rate of methane gas can be measured using a flow meter.
- Methane concentration: The concentration of methane gas in the gas stream can be measured using a gas analyzer.
- Temperature: The temperature of the digester can be measured using a temperature sensor.
- pH: The pH of the digester can be measured using a pH meter.
- Mixing: The mixing of the feedstock in the digester can be monitored using a mixer sensor.
7. Explain the maintenance procedures for a methane gas generation system.
- Regular cleaning: The digester, gas holder, and other components of the system should be cleaned regularly to remove buildup and ensure proper operation.
- Equipment maintenance: All equipment used in the system, such as pumps, blowers, and mixers, should be maintained according to the manufacturer’s instructions.
- Monitoring: The system should be monitored regularly to ensure that it is operating properly and that there are no leaks or other problems.
- Safety checks: Regular safety checks should be conducted to identify any potential hazards and to ensure that the system is operating safely.
8. Describe your experience with troubleshooting problems in methane gas generation systems.
I have experience troubleshooting a variety of problems in methane gas generation systems, including:
- Low gas production: I have experience troubleshooting problems that lead to low gas production, such as insufficient feedstock, low temperature, or poor mixing.
- Gas leaks: I have experience troubleshooting gas leaks in various components of the system, such as the digester, gas holder, and gas lines.
