What is a Gas Booster Pump?

gas booster pump boosts the pressure of gases. It is very helpful for biogas, and also for natural gas pressurization prior to injection into the gas grid. Similar pumps are also for other gases such as nitrogen and helium. The pump works in a simple way. Low-pressure gas gets pushed by the pump and is compressed to become higher-pressure gas.

Gas booster pumps do their job without oil. This makes them great where even a small amount of oil in the gas flow can be a problem. You frequently find them on fuel gas booster skid systems to help deliver the high-pressure needs of engines and turbines.

Different energy sources power these pumps based on what they are used for. Many people use electricity because it's easy to use. That's how a gas booster is!

The gas booster pump should not be confused with gas liquefaction systems. Methane liquefaction requires a different and much higher-pressure type of pump and is used for filling gas cylinders of the type traditionally used for the sale and use of LPG.

Applications of Gas Booster Pumps

Gas booster pumps are used to increase gas flow and pressure in various applications. They play a crucial role in the anaerobic digestion and biogas industry, where they help enhance the efficiency of biogas storage systems.

Increased gas flow and pressure

Gas booster pumps make gas flow faster through the nozzles of gas-burning rings and stoves. They push more gas in less time. This is useful for applications that need a lot of gas quickly or need high calorific heating, like cookers, and power plants with big engines.

Booster pumps take low pressure and turn it into high pressure.

This helps when the source of the gas has bubbled out of the digester tank substrate. At that point, the pressure is low and flows in pipes with a weak to medium force. So, when the endpoint needs a strong gas flow, process designers use a biogas booster pump.

Thanks to this functionality, a biogas booster pump adds great value to all types of biogas systems by enhancing the value of the energy produced.

Anaerobic Digestion and Biogas Industry Applications

Biogas booster pumps play a big part in the anaerobic digestion and biogas industry. But, these are not to be confused with the mixer pumps (e.g. Landia GasMix) that make organic matter break down faster without using oxygen in a biogas digester. They increase the gas yield and hence the flow of gas from the digester tank.

This boosts system performance.

The use of biogas booster pumps helps create a more useful biogas from these systems which in turn generally means that the higher calorific value of the gas after compression is raised.

This is good for both large-scale industries and small-scale owners who need to produce micro-scale or industrial quantities of biogas with little money spent, in order to make a profit.

Benefits of Installing a Gas Booster Pump

Installing a gas booster pump in the pipework between the offtake pipe above the digester tank, from beneath the dome of the gas cover, en route to a gas-holder, offers:

Enhanced biogas storage

Using a gas booster pump can make biogas storage better. It boosts the pressure of the biogas. This higher pressure lets you store more gas in the same space. The pump also keeps the gas safe inside the tank.

So, it's easy to use when you need it later on. Gas booster pumps help keep your biogas system working well and your energy supply steady.

Added Value of Pressurized Biogas

Pressurized biogas has a lot of plus points. It is clean and does not hurt our atmosphere when combusted. It comes from waste – so digester plant operators turn something bad into something good!

Pressurizing the gas also makes it more versatile as an energy source.

The compressed gas burns hot and can power things like stoves, lights, or even large engines.

Another bonus is storing pressurized biogas works well. You keep it in air-tight tanks until you need it. This helps manage supply and demand for energy, especially during peak times of use when it holds a higher sales value.

Preparation for Upgrading Raw biogas to Biomethane

Biogas gets a big lift in value when the methane in it is separated out as pure methane. This makes it a far better product and the cost of upgrading biogas to biomethane usually is less than the increased value. AD upgrading techniques purify biogas into biomethane, which is even better than biogas in terms of sustainability for the future of society/ our children's future.

The mix of impurities in the biogas changes continually within the digester tanks. What we get from upgrading biogas is almost completely methane (CH4) with very little of the other gases left in it.

Gas booster pumps are part of this change. They play a big role in getting raw biogas ready for this important shift to biomethane.

To put it simply these handy pump tools push up the pressure and make sure everything flows right during the biogas production process.

Choosing the Right Gas Booster Pump

When selecting a gas booster pump, consider factors such as flow rate, pressure requirements, and power supply. Find out more, in the section that follows this, about the key specifications to look for in a biogas booster pump that suits your needs.

Considerations for selection

Choosing the right Biogas Booster Pump type and size is crucial. Here are some things to think about:

  1. Check your system's gas-monitored flow characteristics with your design requirements. It should match with the pump for best results.
  2. Look closely at pressure control. Pumps work best if their pressure meets your needs.
  3. The size of your pump matters too. Make sure it fits in well.
  4. Think about natural gas grid system design as well. If you can raise the pressure to the pressure found in the natural gas when fed into the gas grid, you can use it and send it to your buyers via an efficient National Grid pipe network.
  5. Do not forget to read the Operator Guidebook supplied by the pump manufacturer! This book talks a lot about how to make and use biogas, including on farms.

Key specifications to look for

When choosing a gas booster pump for your biogas system, it is important to consider certain key specifications. These specifications will help ensure that the booster pump meets your specific needs and requirements. Here are some important factors to consider:

  1. Flow Rate: The flow rate of the gas booster pump determines how much gas it can handle per unit of time. Make sure to choose a pump with a flow rate that matches the gas production of your biogas system.
  2. Pressure Ratio: The pressure ratio of the booster pump indicates how much it can increase the pressure of the incoming gas. Consider the desired pressure level in your biogas system and choose a pump with an appropriate pressure ratio.
  3. Motor Power: The motor power of the booster pump determines its ability to generate sufficient force to compress the gas. Ensure that the motor power is suitable for handling the gas volume and desired pressure.
  4. Efficiency: Look for a gas booster pump that is energy-efficient, as this can help reduce operating costs and lower environmental impact.
  5. Reliability and Durability: Check for reliable construction and materials that can withstand demanding biogas conditions, ensuring long-term performance and minimal downtime.
  6. Safety Features: Consider explosion-proof ATEX-rated pumps with safety features such as overpressure protection and automatic shutdown mechanisms to prevent accidents or damage.
  7. Ease of Maintenance: Choose a gas booster pump that is easy to maintain, with accessible parts, clear instructions, and availability of spare parts when needed.
  8. Certification: Look for pumps that meet industry standards and have relevant certifications, ensuring quality and compliance with safety regulations.

Single phase and 3-Phase Versions

Biogas booster pumps come in both single-phase and three-phase versions. Single-phase pumps are easier to start but may not be as efficient when used for long periods of time. On the other hand, three-phase pumps require more torque to start but offer better efficiency over extended operation.

When choosing a pump configuration, it's important to understand the power phase requirements of your biogas system. Some applications may require converters to switch between single-phase and three-phase systems.
